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 battery 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) high-accuracy voltage detection circuit;
2) terminal of the charger using high voltage device;
3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);
4) MOS transistor can control the battery charge and discharge;
5) low standby current consumption.
