4S 14.8V 16.8V 20A

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

 

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)

 

Applications:
4S Li-ion18650,LiCoO2,LiMn2O4,Li(NiCoMn)O2 rechargeable batteries
4S Lipo rechargeable batteries

 

BMS solder instruction:
B+ connected battery positive;
B1 the connect point between battery 1 and battery 2
B2 connect the point between battery2 and battery 3
B3 Connect the point between battery 3 and battery 4
B- connect to battery negative end
P- + connection charge / discharge positive;
P- connection charge / discharge negative

P+ P- input output with the same mouth, when combined, the battery capacity, voltage, and internal resistance should be the same. If the combination is good, there is no input and will be charged with an 8.4V voltage, the output must be charged at 16.8V after combined.

Note:
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.
