1) this board is not suit high power electronic tools, if use for screwdriver and drill, please don't buy
2)Above 3A device,means the battry discharge rate is more than 3C.
1C rated battery, 2000mah equals 2ah*1=2A max working current.
3C rated battery means 2ahx3=6A Max working current.
1 x 4S 14.8V 20A Peak Li-ion BMS PCM Battery
