3 string 11.1V lithium battery protection board 10A Working

3 string 18650 lithium battery 10.8V 11.1V 12V 12.6v protection board (can be used for 3 strings and more, maximum support 20)

note:

      This protection board can not be used for iron ion polymer batteries, electric fish battery packs, electric bicycle battery packs, customers who use the above combination purchase, please pay attention! .

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.
