CY- B8+ is designed specially for 3 to 8 LiPo cells in series; it can detect and balance each cell
in a pack while the battery pack is charged. It is important to read the instructions before using
the balancer.
There is 1 balance socket and 2 leads on the right of CY – B8+. You should assure the
connection in accordance with CONNECTION DIAGRAM.
The Chargery LiPo Balancer is an extremely smart device. It can balance any 2S to 8S lithium
polymer battery pack, and automatically cut off the charging process while any cell voltage is
over 4.25V.
Two working ways to balance the battery pack:
Stand-Alone Mode --- without input power.
Balance while Charging mode --- using a LiPo professional charger
Features:
Balance while charge
Balance 2*4S, 2*3S or 4*2S battery packs simultaneously
Automatically cut-off charging circuit while detecting the voltage of cell is over 4.25v
Automatically detect and indicate battery balance status for any 2 to 8 cells pack
Audio alarm for over voltage
Audio alarm for under voltage
LED(s) display each cell in balancing
Reverse polarity an short circuit protection (input an output an Balance
connector)
With Special Connector Conversion Board (CCB) to fit all kinds of battery connectors
Use CY-B8+ to etect an balance (Stan -Alone Mo e):
1. Connect Li-Poly Battery Pack to the CCB
2. Connect B8+ to the plug F on the CCB through the special wire with 9pin connector
3. Press the Start/Stop button,
4. Wait 2-3 seconds until the balance LED indicates battery pack conditions as below:

A: The voltage ifference of the cells in series is un er 0.020V: Blue status LED
and red LED(s) is on for 1-2s, and then off.
B: The voltage ifference of the cells in series is 0.02 to 0.20V: Blue status LED is
off, the red LED(s) flash (on for 5s and off for 3s). These cells are balanced until the red
LED(s) is off.
C: The voltage ifference of the cells in series is over 0.20V: The buzzer will beep
3 times every 5s, at the same time the blue status LED is off, then the red LED(s) flash
(on for 5s and off for 3s). The cells are balanced until the red LED(s) is off.
5. Press the Start/Stop button again to stop the balancing process.
Use CY-B8+ to balance the battery while charge:
While balancing, you can charge the battery, but we suggest you use the professional lipo
charger such as C 50 as the Power supply.
The operating steps are as below:
1. Connect the DC power supply to the lipo charger C 50
2. Connect the B8+ to the CCB through the Special wire
3. Plug the balance connector of the battery pack into the CCB
4. Connect the DC OUT（+）of the B8+ to the battery positive power leads
5. Connect the DC IN (+) of B8+ to the DC out (+) of C 50
. Connect the DC OUT (-) of C 50 to the battery negative power leads
7. Press the Start/Stop on the B8+ to start the balancing process
8. Press the START/ENTER button on the C 50 to start charging process
NOTE:
DC OUT Power lea s is shorter than DC IN power lea s. The shorter power lea is only
been connecte to the positive of the battery pack, an the other is use to connect
the CHARGER such as C650 an Battery pack.
During the charge, the balancer continues to detect and balance each cell as Stand-Alone mode.
When the battery is full charged, the battery is also balanced.
The charging current and the charging voltage will vary depending on the charger. During the
charging process, when the voltage of any cell is over 4.25V or lower than 3.0V, the balancer will
cut off the charging circuit forcibly, at the same time, the blue status LED flash quickly and the
buzzer will beep continuously.
During the charge, the balancer continues to detect and balance each cell, when the difference

of any cell voltage is more than 20mV. The warnings and actions are as below:
Fully charge an balance finishe alerts: all LED is OFF ------- keep the connection
between CY-B + and battery pack
The ifference of any cell voltage is over 0.20V while charging: the buzzer will
beep 3 times every 5s, blue status LED is off, and the red LED(s) flash ( “on” for 5s and
“off” for 3s.) ---- Please reduce charge rate to 0.5A and carefully monitor the balance
status.
Error Alarm an possible reasons:
Red LEDs flash Corresponding cell is balancing and the difference of cell voltage is less
than 200mV. Or any cell voltage is over 4.2V
