Product Description


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

Magnification calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A working current.
In the use of the battery is hot, that means the battery rate is not applicable, this situation can not be used for a long time, the battery will be damaged quickly.
