Product Description

Feature:
4 series 18650 battery 16.8V 16V 14.8V
14.8V (Li-ion 18650 or li-ion battery rated voltage)
16.8V (Li-ion battery full charge voltage)
14.4V ( Lipo battery pack rated voltage)
Note:
1. This board is not suit high power electronic tools, if use for screwdrier 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.
Features:
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.
