www.chargery.com page 2 total 9
Welcome to the CHARGERY 620B intelligent balance charger designed especially for 2 to 6 LiPo and
LiFe cells. Please read the instructions carefully before using the charger.
Special Features
Built-in balancer for LiPo and LiFe cells
The CY-620B has a built-in individual cell balancer. LiPo/LiFe batteries are automatically
balanced during charging ensuring that when the battery is fully charged it is also properly
balanced.
High power and high performance circuit
CY-620B employs the high efficiency circuit. As a result it can charge 6 series of LiPo batteries
with maximal current of 3. 0A. and the case is only 110*68*15.
Perfect safety design
Battery temperature limit
The battery temperature will rise by its internal chemical reaction. The charging process will
be stopped forcibly when the temperature reach 60℃.
Charging time limit
The charging time can be restrained to prevent from any possible defect. When the charging
time reach 5 hours, the charging process will be terminated.
Input voltage monitor
To protect the car battery using as input power from being damaged the input voltage always
monitored. If it drops the 10.0V the charging process will be ended automatically.
At the same time, when you use the AC adaptor or transformer as input power, if the input
voltage is more than 18V the charging process will be terminated to protect the CY-620B from
being damaged.
Light and attractive AL alloy case
High-quality aluminum case is light and durable and very efficient to cool out the internal
heat.
Protection function
Reverse polarity and short circuit protection( input and output)
Over charge and Over current protection
For the battery voltage is less than 2V/cell (for LiFe) or 2.5V/cell (for LiPo), the CY-620B
do not charge to prevent battery damaged.
6 LEDs indicate charging current
6 LEDs display each cell in balancing
1 LED indicate the charging status
With Special Connector Conversion Board(CCB-7KT-XH CCB-7KT-EH CCB-7BC
CCB-723 CCB-723TPQF) and conversion wire(CEHN-7) to fit all kinds of battery
connectors
Charge 2*3S or 3*2S battery packs simultaneously the 2 or 3 packs should be
connected to the CCB firstly and then connect CCB to CY-620B.

Operating instructions
1. Connect the DC power or AC Adapter (12V, up to 5A) to the CY-620B. The charging Current
LED (0.3A) will be on. All LEDs turns on and then off. The beeper will sound. The charger
finished initializing.
2. Choose the battery type by moving the switch in the right of the CY-620B
3. Connect the 2 - 6S battery pack to the CY-620B through the Adapter Board (CCB- KT) and
conversion wire (CEHN- ). The Balance LED will flash; the quantity of flashed LED indicates
the battery count. If the quantity is 5, the battery pack voltage is 18.5V (5S). If the battery
pack is un-balanced, the corresponding LED will blink, start to balance.
4. Press the Current Selection button to adjust the charging current, the corresponding LED
is on.
During the charge, you can press the Current Selection button to adjust the current again.
5. Charging indicator LED should be RED.
6. When the charging indicator is GREEN, and all balance LEDs are off, the battery pack is fully
charged and balanced. When the battery is fully charged, the beeper will sound 10 times.
7. While charge is over if you want to charge another battery with the same battery
type (LiPo or LiFe) please unplug the full battery and then connect the new
battery.
But if the new battery is different battery type with the full battery such as the
new battery is LiFe battery and the full battery just charged is LiPo battery. Please
operate as below:
a) Unplug the full battery
b) Move the switch of battery type to right position.
c) Connect the new battery to the unit.
While charging, the built-in balancer will monitor the voltage of each cell of the battery pack and
control the charging current feeding to each cell to balance the voltage.

cu
There is a Current Selection button on the right of the CY-620B, press the button to choose the
charging current, 6 types of current is be used for the different capacity, we suggest the charging
current is no more than 1C, if the battery capacity is 1000mAh, the charging current is lower than
1000mA.
And switch is for choosing the battery type, lithium polymer or Li-ion battery and LiFe battery cell
can be charged.
For the LiPo battery or li-ion battery, the full charged voltage is 4.2V, and for the LiFe battery, the
voltage is 3. V.
If you need charge the lipo battery to be stored, please choose LiFe battery mode. This is a very
useful feature.
Warning and error message
During charge do not unplug the battery pack from the CY-620B if you want to stop
charging please disconnect the DC POWER or adapter firstly and then unplug the
battery pack.
Do not move the switch to change the battery type during charge. Please choose
battery type before connecting the battery to the charger.
Choose the battery before connecting the battery to the charger.
During charge, any cell voltage is lower than 2V/cell for LiFe battery and 2.5V/cell for LiPo
battery, CY-620B will alarm and stop charging, the charging indictor blinks and the beep
sounds.
When all cell voltage are over 4.25V, all balancing LEDs will flash till the voltage under 4.25V
and the cell voltage is balanced.
When any cell voltage is over 4.30V, the charging indicator is Green, the CY-620B stop
charging. The balance LEDs blink till the battery pack recovery the balance status. If the
battery is balanced, all balance LEDs are off.
Reverse polarity connection on input or output, the CY-620B will not work.
