TET Board for 4S, 14.8V / 16.8V 20A Li-ion Batteries

414.8V 3

 

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 suitable for high powered electronic tools, if used 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.

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.
