3. Intended Use
The charger "V-Charge 120 Touch Duo" has two charge/discharge channels independent of each other.
The charger is operated via a contact-sensitive colour display on which all required displays and operating elements are shown.
The charger is used to charge and discharge rechargeable batteries of the type NiMH/NiCd (1 - 15 cells), LiPo/LiIon/LiFe (1 - 6 cells) and lead acid batteries (1 - 10 cells, 2 V - 20 V).
The charging current can be set between 0.1 A und 12.0 A for each of the two channels. The maximum charging output per channel is 120 W; the total charging output of the charger is 240 W.
The discharging current can be set between 0.1 A and 5.0 A for each of the two channels. The maximum discharging output per channel is 10 W; the total discharging output of the charger is 20 W.
For each of the two charge/discharge channels, there is a connection for a temperature sensor available for battery monitoring (not enclosed, can be ordered as an accessory).
For multi-cell lithium rechargeable batteries, each charge/discharge channel has a separate balancer. Two matching balancer boards (with XH-connections) are enclosed.
The charger has an integrated mains unit to permit operation on mains voltage (switchable between 115 and 230 V/AC, 50/60 Hz). The charger may, however, also be alternatively operated on a stabilised direct voltage of 11 - 18 V/DC (e.g. via an external vehicle lead battery or a suitable mains adapter).
The safety notes and all other information in these operating instructions always have to be observed!

If the charger is operated via the DC input (11 - 18 V/DC), disconnect the charger from the voltage/ power supply.
Then disconnect the connected rechargeable battery from the charger. Do not use the charger again ­bring it to a specialist workshop.
d) Operation
• The charger may be operated either via the mains voltage (switchable 115 V/AC or 230 V/AC, 50/60 Hz) or via a stabilised direct voltage of 11 - 18 V/DC (e.g. via an external vehicle lead battery or a suitable mains adapter).
Use only one of the two connection types, but never both at once. This may damage the charger.
• Do not wear any metal or conductive materials, such as jewellery (necklaces, bracelets, rings, etc.) while you are working with the charger or batteries. A short-circuit at the rechargeable battery or charging cable poses a danger of burns and explosion.
• Do not operate the product unattended. Despite a considerable number of protective circuits, it is impos­sible to exclude the possibility of malfunctions or problems during the charging process.
• Ensure that there is sufcient ventilation during operation. Never cover up the charger. Leave enough of a distance (at least 20 cm) between charger and other objects. Overheating causes a danger of re!
• The charger must only be used to charge (or discharge) rechargeable batteries of types NiMH, NiCd,
LiIon/LiPo/LiFe and lead batteries. Never charge any other rechargeable battery types or non-recharge-
able batteries. There is great danger of re or explosion!
• Always connect the charging cable to the charger rst. Only then must the rechargeable battery be con-
nected to the charging cable.
When disconnecting, proceed in reverse order - rst disconnect the rechargeable battery from the charg­ing cable, then the charging cable from the charger.
If the order is chosen incorrectly, there may be a short-circuit of the charger plugs; there is a danger of
re and explosion!
• Never connect several charges to each other.
• The charger has two charging channels that are independent of each other, so that up to two recharge-
able batteries/rechargeable battery packs can be charged (or discharged) at once. However, only con­nect a single rechargeable battery/rechargeable battery pack to each of the two charging channels. Never connect the charging channels to each other!
• Only operate the product in moderate climate, never in tropical climate. For more information on accept­able environmental conditions, see the chapter "Technical Data".
• Never operate the device immediately after it was taken from a cold room to a warm room. The resulting condensation may lead to malfunctions or damage!
Let the product reach room temperature before taking it into operation again. This may take several hours!
• Avoid operation in direct proximity of strong magnetic or electromagnetic elds, transmitter aerials or HF
generators. This can affect the control electronics.

6. Rechargeable Battery Notes
Although use of rechargeable batteries in everyday life is a matter of course today, there are many dangers and problems. In particular, with LiPo/LiIon/LiFe rechargeable batteries with their high energy content (in comparison with conventional NiCd or NiMH rechargeable batteries), various
regulations must be observed in order to avoid the danger of explosion and re.
For this reason, always ensure that you have read and understood the following information and safety information when handling rechargeable batteries.
If the manufacturer of the rechargeable battery has provided any other information, read it carefully and observe it!
a) General
• Rechargeable batteries are no toys. Always keep batteries/rechargeable batteries out of the reach of children.
• Do not leave rechargeable batteries lying around openly. Children or pets may swallow them. If swal­lowed, consult a doctor immediately!
• Rechargeable batteries must not be short-circuited, taken apart or thrown into re. There is a risk of re
and explosion!
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin when touched without the use of adequate protective gloves.
• Never recharge normal (non-rechargeable) batteries. There is a risk of re and explosion!
Non-rechargeable batteries are meant to be used once only and must be disposed of properly when empty.
Only charge rechargeable batteries intended for this purpose. Use a suitable battery charger.
• Batteries must not get damp or wet.
• Place the charger and battery on a non-ammable, heat-resistant surface (e.g. stone tiles). Maintain enough distance from ammable objects. Leave enough distance between the charger and the re-
chargeable battery - never place the rechargeable battery on the charger.
• As both the charger and the battery heat up during the charge/discharge procedure, it is necessary to ensure sufcient ventilation. Never cover the charger or the rechargeable battery!
• Never use battery packs made up of different cells.
• Never leave the charging/discharging batteries unattended.
• Never recharge a battery directly in the model. Always remove the rechargeable battery from the model
for recharging.
• Always observe correct polarity (plus/+ and minus/-) when connecting the rechargeable battery to your model or charger. Connecting the battery incorrectly will not only damage the model but also the re-
chargeable battery. There is a risk of re and explosion!
This charger has a mechanism that protects against connecting the poles incorrectly. Nonetheless, it is possible that an incorrectly connected battery may lead to damage in certain situations.
10
Page 11
• The charger has two charging channels that are independent of each other, so that up to two recharge­able batteries/rechargeable battery packs can be charged (or discharged) at once. However, only con­nect a single rechargeable battery/rechargeable battery pack to each of the two charging channels. Never connect the charging channels to each other!
• If the product is not to be used for an extended period of time (e.g. storage), disconnect any connected rechargeable battery from the charger and disconnect the charger from the voltage/current supply.
The charger has no mains switch. If you operate the charger via the mains cable, pull the mains plug from the socket when you no longer need the charger.
• Do not charge/discharge any battery that is still hot (e.g. caused by high discharging current from the model). Allow the rechargeable battery to cool down to room temperature before attempting to charge or discharge it.
• Never damage the exterior cover of a battery. There is a risk of re and explosion!
• Never charge/discharge damaged, leaking or deformed batteries. This can result in a re or explosion!
Dispose of any unusable rechargeable batteries in an environmentally compatible fashion. Do not con­tinue to use them.
• Remove the battery from the charger when it is fully charged.
• Recharge the rechargeable batteries about every 3 months. Otherwise, so-called deep discharge may
result, rendering the rechargeable batteries useless.
• Keep rechargeable batteries in a suitable location. Use a smoke detector in the room. The risk of re (or
the occurrence of toxic smoke) cannot be excluded. Special rechargeable batteries for the model con­struction area are subject to great stress (e.g. high charging and discharging currents, vibrations, etc.).
b) Additional Information about Lithium Batteries
Modern batteries with lithium technology do not only have a clearly higher capacity than NiMH or NiCd rechargeable battery packs but they also have a considerably lower weight. This makes this type of re­chargeable battery very interesting for application in model construction; so-called LiPo batteries (lithium­polymer) are often used here.
Rechargeable lithium batteries require special care when charging/discharging, as well as during operation and handling.
For this reason, we would like to provide you with some information in the sections below about the dangers and how you can avoid them, thus helping such batteries to maintain their performance for an extended period of time to come.
Additionally observe chapter 6. a).
• The outer shell of many rechargeable lithium batteries is only made of a thick foil and therefore very sensitive.
Never destroy or damage the battery, never let the battery fall and do not pierce the battery with any objects! Avoid any mechanical strain on the battery; never pull the connection cables of the battery!
There is a risk of re and explosion!
These guidelines must also be observed when the battery is inserted into the model or when it is re­moved from the model.
11
Page 12
• Ensure that the battery does not overheat during usage, recharging, discharging, transport or storage. Do not place the battery next to sources of heat (e.g. speed controller, motor), keep the battery away
from direct sunlight. There is a risk of re and explosion if the battery overheats!
The battery must never heat up to more than +60 °C (observe any additional information from the manufacturer!).
• If the battery is damaged (e.g. after the crash of an aircraft or helicopter model) or the exterior cover is soaked/has expanded, do not use the battery. Do not charge it anymore. There is a risk of re and explo-
sion!
Handle the battery with care, use suitable protective gloves. Dispose of the rechargeable battery envi­ronmentally compatibly.
Never keep such rechargeable batteries in an apartment or a house/garage anymore. Damaged or
bloated lithium rechargeable batteries may catch re suddenly.
• Only use a suitable charger to charge lithium batteries or use the correct charging procedure. Due to a risk of re and explosion, conventional chargers for NiCd, NiMH and lead batteries must not be used!
Always choose the right charging procedure depending on rechargeable battery.
• When charging a lithium battery with more than one cell, always use a so-called balancer (one is already integrated into the supplied charger).
• Charge LiPo batteries with a max. charging current of 1C (if not indicated otherwise by the battery manufacturer!). This means that the charging current may not exceed the capacity value imprinted on the battery (e.g. battery capacity 1000 mAh, max. charging current 1000 mA = 1 A).
With LiFe and LiIon batteries, you must observe the instructions of the battery manufacturer.
• The discharging current must not exceed the value printed on the battery.
For example, if a value of "20C" is printed on a LiPo battery, the max. discharging current is 20 times the battery's capacity (e.g. battery capacity 1000 mAh, max. discharging current 20C = 20 x 1000 mA = 20 A).
Otherwise, the battery will overheat, causing deformation/bloating of the battery or explosion and re!
The printed value (e.g "20C") does not generally refer to the constant current, but to the maximum cur­rent that the battery is capable of producing in the short-term. The constant current therefore should not be higher than one half of the given value.
• Observe that the individual cells of a lithium rechargeable battery must not be deep-discharged. A deep discharge of a lithium rechargeable battery will lead to permanent damage/destruction of the recharge­able battery.
If the model does not provide protection against total discharge or possess a visual display indicating a low battery, remember to switch off the model in time.

The max. charging and discharging currents are indicated with the capacity value "C".
A charging current of 1C corresponds to the capacity value imprinted on the battery (e.g. indicated battery
capacity 1000 mAh, max. charging current 1000 mA = 1 A).
Also observe the correct voltage setting for multi-cell battery packs. For example, the individual cells in a
two-cell battery pack may be switched in parallel or in series.
If the maximum permissible charging current for the rechargeable battery is exceeded or a wrong cell
number/voltage setting is chosen, there is a danger of destroying the rechargeable battery. There also is a
danger of re and explosion from the rechargeable battery!
Further notes on the max. charging current and the cell number/voltage can be taken from the data sheets
or the labels of the rechargeable batteries; these data take precedence over the information in the above table.

a) Connection to a Voltage/Current Supply
The charger offers two different options for operation:
• Operation via the mains voltage (switchable 115 V/AC or 230 V/AC, 50/60 Hz)
• Operation via stabilised direct voltage (11 - 18 V/DC, e.g. via an external vehicle lead battery or a mains adapter)
Attention!
Before connecting the charger to the mains voltage, the right mains voltage must be set at the charger.
Never use both operating modes at the same time. This may damage the charger. Loss of guarantee/war-
The charger has a maximum total charging output of 240 W. If the charger is to be operated via the direct voltage input, the power supply strength must be chosen depending on how high the actually used charging output is (depend­ing on the rechargeable battery type, cell number and the charging current set).
If the charger is not to be operated at a 12 V vehicle lead battery, but via a xed voltage mains unit, it must
When using the direct current input, observe the correct polarity when connecting (plus/+ and minus/-).

b) Connection of a Rechargeable Battery to the Charger
Please observe the following points before connecting or charging/recharging the battery:
• If you have not done so already, please read chapters 5, 6 and 7 completely and ensure that you have understood the information there.
• Do you know all of the information you need to know about your battery? Unknown or unlabelled batter­ies, the necessary values of which you do not know, must not be connected/charged/discharged!
• Have you selected the correct charging/discharging program for the type of battery you are using? Incor- rect settings will damage the charger and the battery; there is a danger of re and explosion!
• Did you set the correct charging or discharging current?
• Have you selected the correct voltage (e.g. for multiple-cell LiPo batteries)? A two-cell LiPo battery may
be switched in parallel (3.7 V) or series (7.4 V).
• Are all connector cables and plugs undamaged, do the plugs stay rmly in the sockets? Worn plugs and
damaged cables should be replaced.
• Connect only one single rechargeable battery or rechargeable battery pack to each of the two charging/ discharging channels of the charger, but never several at once per charging channel. Never connect the two channels to each other! Each of the two channels is independent of the other.
• When connecting a rechargeable battery to the charger, always connect the charging cable to the charg- er rst. Only then must the charging cable be connected to the rechargeable battery. When disconnect­ing, proceed in reverse order (rst disconnect the rechargeable battery from the charging cable, then the
charging cable from the charger).
Failure to do so presents the danger of a short circuit. This can result in a re or explosion of the re­chargeable batteries!
• If you wish to charge battery packs that you have manufactured yourself, the cells must be identical in their construction (same type, same capacity, same manufacturer).
The cells must also be charged to the same level (lithium batteries can be balanced out using the bal­ancer. This is, however, not possible with other battery packs such as NiMH or NiCd).
• Before connecting a rechargeable battery/battery pack to the charger, disconnect it completely, e.g. from a ight or speed controller.
Important when charging/discharging a lithium battery pack with balancer connection:
Multi-cell lithium battery packs usually always have a balancer connection. This permits the charger to monitor the voltage of every single cell separately at all times.
The charger adjusts the voltage of all cells to each other if there are deviations. The balancer prevents that one or
several cells are over-charged or other cells not sufciently fully charged by this. The balancer therefore protects both from over-charging (which may cause re or explosion) and from deep discharge of a single cell, and thus ensures
best performance of the battery pack in your model.

Procedure when connecting a battery pack to the charger:
1. Connect the charger to the voltage/current supply.
2. Select one of the two charging channels. First connect the charging cable to the two 4 mm round sockets of the corresponding charging output (1 or 2). Ensure correct polarity (red cable = plus/+, black cable = minus/-).
The charging cable must not be connected to the rechargeable battery yet! There may be a short-circuit of
the charger plugs; there is a danger of re and explosion!
3. If you want to connect a multiple-cell lithium rechargeable battery to the charger with a balancer cable, connect a balancer board to the respective socket of the charger.
4. Connect the charging cable to the rechargeable battery now. Ensure correct polarity (red cable = plus/+, black cable = minus/-).
5. Connect the balancer plug of a multiple-cell rechargeable lithium battery to the corresponding connection of the balancer board. Do not use any force for plugging in! Ensure correct polarity.
If the balancer plug of the rechargeable battery does not match the shape of the socket on the balancer board, you need to use a matching connection cable (or another balancer board).
Proceed in the following steps when disconnecting a rechargeable battery:
1. If you have connected a lithium rechargeable battery with a balancer cable to the charger, disconnect it from the charger/balancer board.
2. Then disconnect the charging cable from the rechargeable battery.
3. Last disconnect the charging cable from the charger.
Always proceed in this order!
The rechargeable battery must always be disconnected from the charging cable (and from the balancer

10. Lithium Batteries (LiPo, LiIon, LiFe)
a) General
The rechargeable battery programmes for LiPo, LiIon and LiFe rechargeable batteries generally differ only in the volt­ages and the permitted charging current, see table in chapter 7.
When charging a lithium battery, there are two different phases. First, the rechargeable battery is charged with a consistent current. When the rechargeable battery reaches its maximum voltage (at a LiPo rechargeable battery, e.g.,
4.2 V), charging continues at constant voltage (the charging current drops). When the charging current drops below a
certain threshold, charging is ended and the rechargeable battery is fully charged.
If the rechargeable battery has a balancer connection (usually this is the case in almost every lithium bat-
tery with more than one cell), the balancer connection must be connected to the charger as well as the rechargeable battery's cable for charging/discharging.
There are different types of balancer plug. Therefore, do not apply any force if the plug does not t! in the

c) Charging Batteries with Balancer Connection ("BALANCE")
In contrast to the simple rechargeable battery programme "CHARGE" (see chapter 10. b), the rechargeable battery programme "BALANCE" monitors the voltage of every single cell of a multiple-cell lithium rechargeable battery and corrects it accordingly if there are any deviations.
Besides the two normal rechargeable battery connections (plus/+ and minus/-), the balancer connector for the re­chargeable battery must also be connected to the charger via the enclosed balancer board.
There are different types of balancer plug. Therefore, do not apply any force if the plug does not t! in the
charger or the balancer board! The matching adapters for the balancer plugs are available as accessories.
If you use self-customised rechargeable batteries, the balancer plug must be correctly assigned.
The black cable is the minus pole of the rst cell. The next connection pin is the plus pole of the rst cell;
The last connection pin of the balancer plug of the rechargeable battery therefore is the plus pole of the last

Important!
Only a battery pack with exactly the same voltage for each cell provides the maximum performance and
service life for a model airplane/vehicle.
Variations in the quality of the materials used and the internal structure of multiple-cell lithium battery packs
mean that the cells may have different voltages once discharged.
Charging such a rechargeable lithium battery without balancer will quickly cause large differences of cell
voltage. This not only shortens the operating life (as one cell may have a very low voltage), but also dam­ages the rechargeable battery as a result of a total discharge.
When charging a rechargeable lithium battery with different cell voltages without a balancer, there is the
risk of overcharging one cell.
22
Page 23
Example:
A dual-cell LiPo battery pack charged without the use of a balancer appears to have a voltage of 8.4 V and thus ap­pears to be fully charged. The individual cells, however, have a voltage of 4.5 V and 3.9 V (one cell is dangerously overcharged, the other half discharged).
A cell overcharged in this way may leak, expand or, in a worst case scenario, catch re or explode!
If this LiPo rechargeable battery is inserted, e.g. in a model plane, the ying time will be very short, since the voltage
of the half-charged cell will break down quickly and the rechargeable battery will not supply any current anymore.
If your rechargeable lithium battery has a balancer connection, it must be connected to the charger at all
times in addition to the two regular rechargeable battery connections (plus/+ and minus/-) (via the balancer board); always use the charge programme "BALANCE" then rather than the "CHARGE" one.
d) Fast Charge ("FAST CHG")
When charging a lithium rechargeable battery, the charging current reduces continually due to the charging method used, the fuller the rechargeable battery becomes (when the rechargeable battery has reached its maximum charging current and the charger switches from continuous current to continuous voltage charging). This will, of course, also extend the charging time.
At quick charging, the continuous voltage charging method uses a higher charging current. However, this reduces the capacity, because the charge process is terminated earlier due to the safety cut-off in the charger.
This means, a LiPo battery, for example, cannot be fully charged using the fast charge function. Only approx. 90% of the capacity achievable with the normal charge process is available.
Therefore, fast charging is only wise if the battery has to be used again as quickly as possible.
The procedure when setting the charging current and voltage/cell number must be performed as for the rechargeable battery programme "CHARGE"; see chapter 10. b).
e) Storing Batteries ("STORAGE")
This rechargeable battery programme can be used if you want to store the rechargeable battery for an extended period. Depending on the rechargeable battery type set, the rechargeable battery is charged or discharged to a
specic voltage.
Depending on the cell voltage, the battery is either charged or discharged. Of course, with a multi-cell bat-
tery pack, this is only wise if a balancer connection is available and connected to the charger.
At extended storage of a lithium rechargeable battery (e.g. when storing a ight battery over winter), the
The procedure when setting the charging current and voltage/cell number must be performed as for the rechargeable battery programme "CHARGE"; see chapter 10. b).
rechargeable battery should in any case be checked every 3 months and treated with the rechargeable battery programme "STORAGE" again to prevent harmful deep discharge.
23
Page 24
f) Discharging Battery ("DISCHARGE")
Normally, it is not necessary to discharge lithium batteries (contrary to NiCd batteries) before charging. The battery can be charged immediately, independent of its current status. If you want to discharge a rechargeable lithium battery anyway, you can set the discharge current.
The maximum possible discharging current depends on the battery type, battery capacity and number of
cells. The max. discharge output of the charger is 10 W per channel. This limits the max. possible discharge current of rechargeable batteries with multiple cells.
Discharge a lithium rechargeable battery only to the minimum permitted discharge end voltage per cell (see
table in chapter 7 or observe information of the rechargeable battery manufacturer). If the rechargeable battery is discharged any further, this deep discharge will permanently damage it and render it useless!
The procedure when setting the discharging current and voltage/cell number must be performed the same as when charging, see chapter 10. b), except that the rechargeable battery is not charged, but discharged after starting the rechargeable battery programme.

11. NiMH and NiCd Rechargeable Batteries
a) General
The rechargeable battery programmes for NiMH and NiCd rechargeable batteries generally differ only in
the internally used charging procedures. The settings in the menus are the same.
The charger must be in the main menu.
Use the buttons "NiMH" or "NiCd" to select the battery type match­ing the rechargeable battery used. The respective interface is marked in colour.
If you push the same button again, the charger will start setting mode for the selected rechargeable battery type.
In the gure on the right, a NiMH rechargeable battery has been
chosen. The menus for NiCd rechargeable batteries are the same, however.
"CELLS" = Cell number of the rechargeable battery
"MODE" = Charging/discharging mode
"CURRENT" = current
"MORE" = Display further settings
"BACK" = Return to the previous menu
"START" = Start the set charging/discharging mode (keep the button pushed for 3 seconds)
The following charge/discharge modes exist for NiMH and NiCd rechargeable batteries:
• "CHARGE": Charge rechargeable battery
• "AUTO CHG.": Select the charge current according to the rechargeable battery
• "DISCHARGE": Discharging the rechargeable battery
• "RE-PEAK": Repeat the charge end recognition
• "CYCLE": Perform multiple discharge/charge cycles
25
Page 26
b) Charging Batteries ("CHARGE")
The charging current to be set depends on the rechargeable battery's capacity and is usually 1C (also see chapter 7). High-quality rechargeable batteries also can stand a charging current up to 2C. However, you should always observe the battery manufacturer's instructions.
The value "1C" means that the charging current is equivalent to the battery's capacity. A charge current of
3 A therefore must be set for a 3000 mAh-NiMH battery at 1C.
A value of 0.5C means that the charging current corresponds to half the capacity value. At a NiMH re-

• If you push the button "START" for the duration of 3 seconds, the charger will review the connected rechargeable
battery (the display will show "CHECK BATTERY.....").
Charging starts when everything is OK.
If errors are found (e.g. if no rechargeable battery is connected), the corresponding message will be displayed. The button "BACK" will return you to the previous menu in that case.
• After charging starts, various information is displayed.
• Use the button "GRAPH" to get to the graphical display of the
voltage curve and charge current.
• Push the button "STOP" to manually interrupt or terminate charg-
ing.
• When charging is complete, the charger will emit a sound and
a corresponding message will be displayed. The button "STOP" will take you back to the setting menu.
c) Automatic Charge Mode ("AUTO CHG.")
In automatic mode, the charger checks the rechargeable battery condition (e.g. the inner resistance) and calculates the charging current from this. You need to set an upper limit for the charging current so that the rechargeable battery is not damaged by a too-high charging current.
Depending on the rechargeable battery and its inner resistance, shorter charging times may be achieved in the rechargeable battery programme "AUTO CHG." than in the rechargeable battery programme "CHARGE" (chapter
11. b).
Proceed as in the rechargeable battery programme "CHARGE" for setting and operation (chapter 11. b).
The only difference is that you do not set the actual charging current, but the limit for the maximum charging
current that the charger must not exceed.
27
Page 28
d) Recharge Rechargeable Battery Again ("RE-PEAK")
The charger automatically ends charging of NiMH and NiCd rechargeable batteries when the rechargeable battery is fully charged. Recognition of when the rechargeable battery is fully charged is according to the delta-U procedure.
The rechargeable battery programme "RE-PEAK" performs this recognition again. This way, you can not only ensure that the rechargeable battery is truly fully charged, you can also check how well the rechargeable battery can take quick charging.
Proceed as follows:
• First, charge the rechargeable battery completely (see chapter 11. b) or chapter 11. c)). Then select the recharge­able battery programme "RE-PEAK".
• After you have set the rechargeable battery data and charge current, push the button "START" for 3 seconds.
• An input eld will appear, indicating how often the recognition processes for the delta-U charging procedure are to
be performed. Set the number with the "-" and "+" buttons.
• Keep the "START" button pushed again for 3 seconds to start the rechargeable battery programme "RE-PEAK".
The remaining operation corresponds to the rechargeable battery programme "CHARGE" (chapter 11. b).
e) Discharging Battery ("DISCHARGE")
To put partially charged NiMH/NiCd rechargeable batteries into a dened starting condition, they can be discharged
with this rechargeable battery programme.
The maximum possible discharging current depends on the battery type, battery capacity and number of
cells. The max. discharge output of the charger is 10 W per channel. This limits the max. possible discharge current of rechargeable batteries with multiple cells.
Specically NiCd rechargeable batteries should not be recharged from a partially discharged condition, since the
capacity may reduce by this (memory effect). This is usually not a problem in modern NiMH rechargeable batteries.
The rechargeable battery can also be used to measure the capacity of rechargeable batteries.
The procedure when setting the discharging current and voltage/cell number must be performed the same as when charging, see chapter 11. b), except that the rechargeable battery is not charged, but discharged after starting the rechargeable battery programme.
28
Page 29
f) Cycle Programme ("CYCLE")
To test rechargeable batteries, form new rechargeable batteries or refresh older rechargeable batteries, you can perform up to 5 cycles in sequence automatically. The two possible combinations are "Charge/Discharge" and "Discharge/Charge".
The discharge current used will be the value you have set in the charge programme
("DISCHARGE").
Proceed as follows:
• Set the discharge current in the rechargeable battery programme "DISCHARGE" (see chapter 11. e).
• Switch to the rechargeable battery programme "CYCLE". Set the rechargeable battery data (cell number, charge
current) here as usual.
• Keep the button "START" pressed for 3 seconds.
• A new input eld appears.
• For "CYCLE COUNT", you can enter the cycle number (1....5), for how often the charging/discharging process is to
be performed.
• In "MODE", you can set the sequence. "Chg>dChg" means "Charging/Discharging" and "dChg>Chg" means "Discharging/Charging".
• Keep the "START" button pushed again for 3 seconds to start the rechargeable battery programme.
The remaining operation corresponds to the rechargeable battery programme "CHARGE" (chapter 11. b).

12. Lead Batteries (Pb)
a) General
Lead batteries are completely different from lithium, NiMH or NiCd batteries. Despite their high capacity they can only provide low currents. The charging process is also different.
The charging current for modern lead batteries must not exceed 0.4C; 1/10C is perfect for lead batteries.
A higher charging current is not permitted; it would overload the rechargeable battery! This not only causes
danger of explosion and re, but also danger of injury from the contained acid.
Also always observe the information printed on the battery or the information provided by the battery
The charger must be in the main menu.
Push the button "Pb". The button is highlighted in colour.
If you push the same button again, the charger will start setting mode for the selected rechargeable battery type.
"CELLS" = Cell number of the rechargeable battery
"MODE" = Charging/discharging mode
"CURRENT" = current
"MORE" = Display further settings
"BACK" = Return to the previous menu
"START" = Start the set charging/discharging mode (keep the button pushed for 3 seconds)
There are the following charging/discharging modes:
• "CHARGE": Charge rechargeable battery
• "DISCHARGE": Discharging the rechargeable battery
manufacturer on the permitted charging current.
30
Page 31
b) Charging Batteries ("CHARGE")
The charging current to be set depends on the battery capacity and is usually 0.1C (also see chapter 7). High-quality lead batteries also can stand a charging current up to 0.4C. However, you should always observe the battery manu­facturer's instructions.
The value "0.1C" means that the charging current is equivalent to one-tenth of the rechargeable battery's
capacity. For a lead battery with a capacity of 5000 mAh (= 5 Ah) the charging current at 0.1C must be set to 0.5 A.
Proceed as follows to charge a lead battery:
• First select the rechargeable battery type in the main menu, as described in chapter 12. a) ("Pb").
• Select the cell number in "CELLS" with the buttons "-" and "+".
• Push the button ">" in "MODE" repeatedly until the mode
"CHARGE" is displayed.
• For "CURRENT", use the buttons "-" and "+" to set the charge current. Keep the respective button pressed for quick adjust­ment.
• Another input window appears when you push the button "MORE".
For "CHARGE", a maximum cell voltage can be set when charg­ing.
For "DISCHARGE", you can set the minimum cell voltage when discharging.
• If you push the button "START" for the duration of 3 seconds, the charger will review the connected rechargeable battery (the
display will show "CHECK BATTERY.....").
Charging starts when everything is OK.
If errors are found (e.g. if no rechargeable battery is connect­ed), the corresponding message will be displayed. The button "BACK" will return you to the previous menu in that case.
• When charging is complete, the charger will emit a sound and a corresponding message will be displayed. The button "STOP" will take you back to the setting menu.
31
Page 32
c) Discharging Battery ("DISCHARGE")
To put partially charged lead batteries into a dened starting condition, they can be discharged with this rechargeable
battery programme.
The maximum possible discharging current depends on the battery type, battery capacity and number of
cells. The max. discharge output of the charger is 10 W per channel. This limits the max. possible discharge current of rechargeable batteries with multiple cells.
The rechargeable battery can also be used to measure the capacity of rechargeable batteries.
The procedure when setting the discharging current and voltage/cell number must be performed the same as when charging, see chapter 12. b), except that the rechargeable battery is not charged, but discharged after starting the rechargeable battery programme.
32
Page 33
13. Voltage indication
The charger can also display the current voltages of the cells of a lithium rechargeable battery.
For this, the rechargeable lithium battery must have a balancer connection that must be connected to the
charger (via the balancer board).
For NiMH, NiCd and lead batteries, the overall voltage of the connected rechargeable battery is displayed. Display of individual cell voltages is not possible for construction principle reasons (these rechargeable batteries have no balancer connection).
Proceed as follows:
• Connect the rechargeable battery to the charger via the charging cable as usual. Connect Lithium rechargeable batteries with a balancer connection to the charger via the balancer board as well.
• Push the button "BATT.METER" in the main menu to call the voltage display.
• The display shows the total voltage ("MAIN") of the connected rechargeable battery.
• If a Lithium rechargeable battery is connected to the charger via the balancer connection, the individual cell voltages appear (depending on the cell number of the connected rechargeable battery; the gure on the right shows a 6-cell Lithium recharge­able battery).
• Use the button "BACK" to return to the main menu.

14. Loading/Changing/Saving Rechargeable Battery Data
The charger has a total of 6 memories in which you can save rechargeable battery data/settings. They can
be loaded again on demand. This way, frequently used rechargeable battery programmes with the associ­ated rechargeable battery data can be loaded without having to tediously set them again.
The charger must be in the main menu.
Push the "PROGRAM" button to set up the memories.
In the delivery condition and after a reset, all memories are pre­assigned (e.g. 2-cell LiPo battery), but can, of course, be changed according to your wishes.
Select one of the 6 memories by pushing the corresponding key/ button as usual.
Use "EDIT" to change the data of your memory; see below.
Use the button "LOAD" to load the rechargeable battery data of the memory. The charger will then jump right to the respective rechargeable battery function where you can start the associated rechargeable battery programme.
Use the button "BACK" to return to the main menu.
If you have selected "EDIT", you can now change the memory.
You can use the buttons to select the rechargeable battery type and the cell number, charging procedure (depending on the recharge­able battery type set), the charge current and discharge current.
Push the button "CONFIRM" to save the settings made.
The saved data are not lost if the charger is discon-
nected from the operating voltage.

15. System Menu
Various basic settings are summarised in the system menu of the charger, pre-dened with the most common values.
The charger must be in the main menu.
Push the "SYSTEM" button to show the system menu.
The following functions are available:
• "KEY": You can switch the conrmation sound for every push of
a button on ("ON") or off ("OFF") here.
• "BUZZER": In this function, the signal sound for various func­tions/warning messages can be switched on ("ON") or off ("OFF").
• "LANGUAGE": Select the language for the menus and informa­tion in the display.
• "INPUT LOW": If the charger is connected to a car's lead battery (instead of via the mains cable), you can set the voltage limit here. If this is undercut, the charger terminates charging of the connected rechargeable battery and a warning sound is emitted.
This setting protects the vehicle lead battery from deep dis­charge.
• "LCD LIGHT": Set the backlighting brightness of the display here.
• "REST TIME": For the cycle program at NiMH/NiCd recharge-
able batteries, you can set the duration of the break that the charger is supposed to make before charging/discharging or discharging/charging here. This gives the rechargeable battery
time to cool off sufciently before the next cycle starts.
• "ABOUT": The charger displays the version number of the rmware. There also is a function here to restore all fac-
tory settings ("LOAD FACTORY"); all settings and memories will be deleted after a prompt.
• "SAFETY OPTION": The chager displays another setting menu; see next page.
• "BACK": Use this button to return to the main menu.
35
Page 36
On the rst page of the system menu, push the button "SAFETY OPTION", another setting menu appears.
"TIM.": If charging starts, the internal safety timer starts as well. If the charger cannot detect whether the battery is fully charged for whatever reason (e.g. with delta-U-recognition), the charging will be terminated automatically after the end of the time set here if the safety timer is on. This protects the battery from overloading. The safety timer can be switched on ("ON") or off ("OFF") by pushing the button "TIM"; the time for the safety timer can also be changed with the buttons "-" and "+".
Do not set the time too short, since the rechargeable battery cannot be fully charged then because the
safety timer will cancel charging prematurely.
Calculate the time for the safety timer as follows (examples):
Battery capacity Charging current Timer time
2000 mAh 2.0 A 2000 / 2.0 = 1000 / 11.9 = 84 minutes
3300 mAh 3.0 A 3300 / 3.0 = 1100 / 11.9 = 92 minutes
1000 mAh 1.2 A 1000 / 1.2 = 833 / 11.9 = 70 minutes
The factor 11.9 is used to permit charging 140% of the rechargeable battery capacity (the rechargeable
battery is guaranteed to be fully charged then), before the safety timer trips.
"CAP.": This safety function of the charger terminates charging automatically when a certain capacity has been "load­ed" into the battery. The safety function can be switched on ("ON") or off ("OFF") by pushing the button "CAP"; the capacity can also be changed with the buttons "-" and "+".
However, do not set a capacity which is too low; otherwise the rechargeable battery cannot be fully
charged.
"TEM. CUT": The charger can automatically cancel charging/discharging if the rechargeable battery exceeds the temperature set here. Set the temperature with the button "+" or "-".
To use this function, an external temperature sensor is required (not enclosed, can be ordered as an ac-
cessory). It must be connected to the respective socket of the respective charge/discharge channel of the charger.
• "BACK": This button returns you to the previous setting menu.
