SPECIAL FEATURES

Optimized operating software

iMax B6 features the so-called AUTO function that set the feeding current
during the process of charging or discharging. Especially for Lithium
batteries, it can prevent the overcharging which may lead to an explosion
due to the user's fault. It can disconnect the circuit automatically and
alarm once detecting any malfunction. All the programs of this product
were controlled through two way linkage and communication, to archive
the maximum safety and minimize the trouble. All the settings can be
configured by users!

Internal independent Lithium battery balancer

iMax B6 employs an individual-cell-voltage voltage balancer. It isn’t
necessary to connect an external balancer for balance charging.

Balancing individual cells battery discharging

During the process of discharging, iMax B6 can monitor and balance each
cell of the battery individually. Error message will be indicated and the
process will be ended automatically if the voltage of any single one cell is
abnormal.

Adaptable to various type of Lithium battery

iMax B6 is adaptable to various type of Lithium battery, such as LiIon,
LiPo and the new LiFe series of battery.

Fast and storage mode of Lithium battery

Purposes to charge Lithium battery varies, ‘fast’ charge reduce the
duration of charging, whereas ‘store’ state can control the final voltage
of your battery, so as to store for a long time and protect useful time of the
battery.

Maximum safety

Delta-peak sensitivity: The automatic charge termination program based
on the principle of the Delta-peak voltage detection. When the battery's
voltage exceeds the threshold, the process will be terminated
automatically.

Automatic charging current limit

You can set up the upper limit of the charging current when charging your
NiCd or NiMH battery; it is useful for the NiMH battery of low impedance
and capacity in the 'AUTO' charging mode.

Capacity limit

The charging capacity is always calculated as the charging current
multiplied by time. If the charging capacity exceeds the limit, the process
will be terminated automatically when you set the maximum value.

Temperature Threshold*

The battery’s internal chemical reaction will cause the temperature of the
battery to rise. If the temperature limit is reached, the process will be
terminated.
* This function is available by connecting optional temperature probe,
which is not included in our package.

Processing time limit:

You can also limit the maximum process time to avoid any possible defect.

Input power Monitoring

To protect the car battery used as DC input power from being damaged, its voltage
keeps being monitored. If it drops below the lower limit, the process will be ended
automatically.

Data store/load

The maximum five batteries’data can be stored for users’convenience. You can keep
the data pertaining to program setting of the battery of continuous charging or
discharging. Users can call out these data at any time without any special program
setting.

Do not connect more than one battery pack to this charger at
any one time.

Never attempt to charge or discharge the following types of
battery.

“ A battery pack which consists of different types of cell

(including different manufacturers)

“ A battery that is already fully charged or just slightly

discharged.

“ Non-rechargeable batteries (Explosion hazard).
“ Batteries that require a different charge technique from

NiCd, NiMh, Li-Poly or Gel cell (Pb, Lead acid).

“ A faulty or damaged battery.
“ A battery fitted with an integral charge circuit or a

protection circuit.

“ Batteries installed in a device or which are electrically

linked to other components.

“ Batteries that are not expressly stated by the

manufacturer to be suitable for the currents the charger
delivers during the charge process.

Please bear in mind the following points before commencing
charging:

“ Did you select the appropriate program suitable for the type of

battery you will be charging?

“ Did you set up adequate current for charging or discharging?

“ Have you checked the battery voltage? Lithium battery packs

can be wired in parallel and in series, i.e. a 2 cell pack can be

3.7V (in parallel) or 7.4V (in series).

“ Have you checked that all connections are firm and secure?

Make sure there are no intermittent contacts at any point in the
circuit.

“

Do not attempt to disassemble the battery pack arbitrarily.

Charging

During charge process, a specific quantity of electrical energy is fed into the
battery. The charge quantity is calculated by multiplying charge current by
charge time. The maximum permissible charge current varies depending on the
battery type or its performance, and can be found in the information by the
battery manufacturer. Only batteries that are expressly stated to be capable of
quick-charge are allowed to be charged at rates higher than the standard
charge current.

Connect the battery to the terminal of the charger: red is positive and black is
negative. Due to the difference between resistance of cable and connector, the
charger can not detect resistance of the battery pack, the essential requirement
for the charger to work properly is that the charge lead should be of adequate
conductor cross-section, and high quality connectors which are normally gold­plated should be fitted to both ends

Always refer to the manual by the battery manufacturer pertaining to charging
methods, recommended charging current and charging time. Especially, the
Lithium battery should be charged according the charging instruction provided
by the manufacturer strictly.

It should be paid attention to the connection of Lithium battery especially.

Do not attempt to disassemble the battery pack arbitrarily

Please get highlighted that Lithium battery packs can be wired in parallel and in series. In the
parallel connection, the battery s capacity is calculated by multiplying single battery s
capacity by the number of cells with total voltage stay the same. The voltage s imbalance may
cause fire or explosion .Lithium battery is recommended to charge in series.

Discharging

The main purpose of discharging is to clean residual capacity of the battery, or
to reduce the battery’ voltage to a defined level. The same attention should be
paid to the discharging process as charging. The final discharge voltage should
be set up correctly to avoid deep-discharging. Lithium battery can not be
discharged to lower than the minimum voltage, or it will cause a rapid loss of
capacity or a total failure. Generally, Lithium battery doesn’t need to be
discharged. Please pay attention to the minimum voltage of Lithium battery to
protect the battery.

Some rechargeable batteries have a memory effect. If they are partly used and
recharged before the whole charge is accomplished, they remember this and
will only use that part of their capacity next time. This is a ‘memory effect’ It is
said that NiCd and NiMH batteries are suffering from memory effect. NiCd has
more memory effect than NiMH.

Lithium batteries are recommended to be discharged partially rather than fully
discharged. Frequent full discharging should be avoided if possible. Instead,
charge the battery more often or use a battery of larger capacity.

Full capacity cannot be used until it has been subjected to 10 or more charge
cycles. The cyclic process of charge and discharge will optimize the capacity of
battery pack.

Lithium battery. There are three kinds of
Lithium battery: LiFe(3.3V), Lilo(3.6V) or
LiPo(3.7V). This information is of critical
importance that you have to check the
battery carefully to make sure it is set up

+

correctly. If it is different from correct

INC

value, explosion can occur during charge
process.

To avoid from erroneous setting by
users,iMax B6 detects the cell count of
Lithium battery automatically at the
beginning of charge or discharge process.

+

But battery that is deep-discharged can't

INC

be detected correctly. To avoid this error,
the time term can be set to verify the cell
count by the processor. Normally, 15
seconds are enough to detect the cell
count correctly. You need to extend the
time term limit for the battery of large
capacity. But the charge or discharge
process may come to an end within the

+

time term because of the time limit

INC

decided by the wrong count if you set too
long time limit for the battery of small
capacity. This may cause fatal error. You
have to extend the time term if the
processor detect the cell count incorrectly
at the beginning of charge or discharge
process. Otherwise, default value is

+

recommended to use.

INC

This shows the trigger voltage for
automatical charge termination of NiMH
and NiCd battery. The valid value ranges
from 5 to 20 mV per cell. Setting the
trigger voltage higher brings a danger of
overcharging; whereas setting it lower
brings a possibility of premature

++

termination. Please refer to the technical

INCINC

specification of the battery.(NiCd
default:12mV, NiMH default:7mV)

of overcharging; whereas setting it lower brings a possibility of premature
termination. Please refer to the technical specification of the battery.(NiCd
default:12mV, NiMH default:7mV)
There is a 3-pin port on the left of the charger used as USB interface or
temperature sensor port. If the screen displays temperature, you can use
the optional temperature probe to connect to the surface of the battery. If it
displays the USB port, you can connect the charger to your PC through the
optional USB cable to monitor the charging process through optional
software.
The maximum temperature of the battery can be set during the charge
process. The process will be terminated automatically to protect battery
once the temperature of battery reaches this value. This feature is
accomplished through temperature probe (optional).

The battery becomes warm after
cycles of charge/discharge process.
The program will insert a time delay
after each charge/discharge process
for the battery have enough time to
cool down before beginning next
cycle of charge/discharge process.
The valid value ranges from 1 to 60
minutes.

When the charge process starts, the
integrated safety timer starts to run
simultaneously. If error detected or
the termination circuit can not detect
if the battery is fully charged, this unit
is programmed to prevent
overcharging. Please refer to the
following to calculate the time you set.

The program provides maximum
capacity protection function. If the
Delta-peak voltage can not be
detected or the safety timer times out,
the charge process will stop
automatically, when the battery
reaches the user-set maximum
charge capacity,

The beep to confirm users' operation
sounds every time a buttons is
pressed. The beep or melody sounds
at various times during operation to
confirm different mode change.
These functions can be switched on
or off.

This function monitors the voltage of
the input battery used to power this
charger. If the voltage is lower than
user-set value, the program will end
forcibly to protect the input battery.

Safe timer Calculation

When charging NiCd or NiMH batteries, divide the capacity by current,
then divide the result by 11.9, set this number of minutes as the value for
safety timer setting. If the charger stopped at this time threshold, about
140% of the capacity will have been fed into the battery.
For example:
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes

Lithium Lilo/LiPo/LiFe program

The program is only suitable for charging/discharging Lithium-polymer
batteries with a nominal voltage of 3.3/3.6/3.7V/cell. Different batteries
have different charge technique. There are two methods termed as
constant voltage and constant current. The charge current varies
according to battery capacity and specification. The final voltage is very
important; it should precisely match the voltage of the battery: LiPo is 3.6V,
LiLo is 4.1V and LiFe is 3.6V. The current and voltage of the battery should
be correctly set.
When you want to change the values of parameters, please press
START/ENTER key to make it blink and then use DES or INC to change the
value. Then press START/ENTER key again to store the value.

Pb lead-sulphuric acid battery program

This program is only suitable for charging Pb lead-acid battery with
nominal voltage from 2 to 20V. Pb lead-acid battery is completely
different from NiCd/NiMH battery. These batteries can only deliver current
lower in comparison to their capacity. The same restriction applies to the
charging process. Consequently, the optimum charge current can only be
1/10 of the capacity. Pb battery can not be used for fast-charging, please
follow the instructions provided by the battery manufactures.

You can press START/ENTER key to make it blink and alter the value of
parameters using INC or DEC key, press START/ENTER key to store the
value.
