3S 10A 11.1V BMS lithium battery protection board 18650 or 3.7V overcurrent 20A current limit AOD403 +8254AA program

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.
note:
This protection board can not be used for iron ionized polymer batteries, electric fish battery packs, electric bicycle battery packs,
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.
