4S 14.8V / 16.8V 20A peak li-ion BMS PCM battery protection board bms pcm for lithium LicoO2 Limn2O4 18650 li batteryNOTE:
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.
