3S 12V 13 A lithium battery protection board

The power range described applies to the following products:

     Low power inverter, massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring standby power supply, and other products.

Note: For discharge products above 3A, the discharge rate of the battery should be more than 3C.

Magnification calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A maximum working current.

3C rate battery, 2000 capacity is equal to 2AH*3=6A maximum working current.

In the use of the battery will be hot, the battery rate is not applicable, this situation must not be used for a long time, the battery will be damaged quickly.

Note 1: In strict accordance with the diagram wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B +), do not intentionally short circuit!

Note 2: After the line is connected, it needs to be charged and activated before there is output.

Note 3: When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please fill each set of batteries separately and use them in series. . . In the discharge test, the battery with the fastest voltage drop is the poor battery.

For some customers with poor electronic foundation, please explain: Do not mix good battery and poor battery! The closer the capacity/internal resistance of the three batteries is, the better! (The effect of 2 good batteries + 1 poor battery) = 3 use of poor battery).
