5 pcs/lot BMS 4S 14.8V/16.8V 20A 18650 Li-ion Charge Protection Board Balancer for LicoO2 Limn2O4 Charging
4 series 18650 16.8V 16V 14.8V
14.8V (Li-ion 18650 or li-ion rated voltage)
16.8V (Li-ion full charge voltage)
14.4V ( Lipo 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 , 2000mah equals 2ah*1=2A max working current.
3C rated 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 charge and discharge;
5) low standby current consumption.
