Special Features

Balancing Individual Cells Battery During Discharging

During the process of discharging, SKYRC D260 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.

Fast Charge and Storage Mode of Lithium Battery

Function of the two modes differs from each other. “FAST CHG” minimizes battery charge
time, while “STORAGE” has the capacity to control the final battery voltage, which is
necessary and helpful for a rarely used battery.

Re-Peak Mode of NiMH/NiCd Battery

In re-peak charge mode, the charger can peak charge the battery once, twice or three
times in a row automatically. This is good for making the battery fully charged.

Delta-peak Sensitivity for NiMH/NiCd

Delta-peak sensitivity for NiMH/NiCd battery: 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.

Cyclic Charging/Discharging

1 to 5 cyclic and continuous process of charge > discharge or discharge > charge is
operable for battery refreshing and balancing to stimulate the battery's activity.

Automatic Charging Current Limit

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

Battery Voltage Meter

The user can check battery's total voltage, the highest voltage, the lowest voltage and
each cell's voltage.

Battery Internal Resistance Meter

The user can check battery's total internal resistance and each cell's internal resistance.

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.

Processing Time Limit:

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

USB Power 5V/2.1A

You can charge your phone and tablet using the built-in USB power output port.

Warning And Safety Notes

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

A battery pack which consists of different types of cells (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, LiPo 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 are
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.

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 battery manufacturer about charging methods,
recommended charging current and charging time. Especially, the lithium battery
should be charged according the charging instruction provided by the manufacturer
strictly.

· 06

D260

Warning And Safety Notes

Attention should be paid 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 capacity by the number of cells with total voltage stay the same. The voltages
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.

Commonly Used Terms

Commonly used terms

Final charge voltage: the voltage at which the battery's charge limit (capacity limit) is
reached. The charge process switches from a high current to a low maintenance rate
(trickle charge) at this point. From this point on further high current charging would cause
overheating and eventual terminal damage to the pack.

Final discharge voltage: the voltage at which the battery's discharge limit is reached. The
chemical composition of the batteries determines the level of this voltage. Below this
voltage the battery enters the deep discharge zone. Individual cells within the pack may
become reverse polarized in this condition, and this can cause permanent damage.

A, mA: unit of measurement relating to charge or discharge current.1000 mA = 1 A
(A=Ampere,mA=Milliampere)

Ah, mAh: unit of measurement for the capacity of a battery (Amperes x time unit; h = hour).
If a pack is charged for one hour at a current of 2 A, it has been fed 2 Ah of energy. It
receives the same quantity of charge (2 Ah) if it is charged for 4 hours at 0.5 A, or 15
minutes (=1/4 h) at 8 A.

'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers recommend
charge and discharge currents based on the battery 'C' rating. A battery's '1C' current is the
same number as the battery's rated capacity number, but noted in mA or amps. A 600mAh
battery has a 1C current value of 600mA, and a 3C current value of (3 x 600mA) 1800mA or

1.8A. The 1C current value for a 3200mAh battery would be 3200mA (3.2A).

Nominal voltage(V): The nominal voltage of the battery pack can be determined as follows;

-.NiCd or NiMH: multiply the total number of cells in the pack by 1.2. A 8-cell pack will have a
nominal voltage of 9.6 volts (8x1.2).

-.LiPo: multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will
have a nominal voltage of 11.1 volts (3x3.7).

-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in series will have
a nominal voltage of 7.2 volts (2x3.6).

-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiIo wired in series will have
a nominal voltage of 13.2 volts (4x3.3).

-.LiHV: multiply the total number of cells in the pack by 3.7V. A 4-cell LiHV wired in series will
have a nominal voltage of 14.8 volts (4x3.7).
If the nominal voltage of the battery is not printed on the battery's label, consult your battery
manufacturer or supplier. Do not guess the rated voltage of battery.
