4S10A BMS For Li-ion Lithium Battery 14.8V 16.8V Protection

4. Use manual:
. Connect 4pcs lithium battery at B+,B3,B2,B1,B- . P+ and P- is output or input

5. Using attention:
1>. Please strictly follow the wiring diagram: 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B+), do not intentionally short-circuit!
2>. After connecting the wire, it needs to be charged before it has output.
3>. In series 4 batteries, please ensure that the voltage of each battery is the same. If it is different, please charge each battery separately and then use it in series. In the discharge test, the rapidly decreasing of voltage battery is the
poor battery.
4>. Don’t mix good batteries with bad batteries!The more similar the battery capacity or internal resistance, the better!(The effect of 2 good batteries +2 poor batteries = The effect of 4 poor batteries).

6. Caution:
1>. The battery protection board cannot be used for lithium iron phosphate battery, hernia lamp, hand electric drill battery pack, electric fish electromechanical battery group, electric bicycle battery pack, children’s car battery, 775(4A) above the motor, 1W fisheye LED light.
2>. For the discharge products with 3A current and above, the discharge ratio of the battery should be above 3C.
3>. Multiplier calculation formula:1C multiplier battery, 2000mAh capacity is equal to 2AH*1=2A upper limit working current.3C multiplier battery, 2000mAh capacity is equal to 2AH*3=6A upper limit working current.
4>. In use, if the battery is hot, it means that the battery multiplier is not applicable. This situation cannot be used for a long time, and the battery will be damaged quickly.

7. Application:
1>. Small power inverter
2>. Massager battery pack
3>. LED lamp backup power
4>. Electronic products
5>. Solar street lamp battery pack
6>. Monitoring standby power supply

Note:- Actual Product may be a little Different but the working principal & other features are the same as describing.This BMS not for LFP batteries
