Short cut protection: protector, repair size change: 35 * 35 * 3.0mm
BMS welding instruction  :
B + battery connected positive;
B1 the connection point between battery 1 and battery 2
B2 connect point between Battery 2 and Battery 3
B3 Connect the point between battery 3 and battery 4
Connection B to the negative end of the battery
P- + connection charge / positive discharge;
Connection charge P / negative discharge

Note :

1) This table is not suitable for high-power electronic tools, if it is used for screwdrivers and drills,
please do not buy.
2) By 3A Above the device, it means the battery discharge rate is more than 3C.
1C rated battery, 2000mah equals 2ah * 1 = 2A maximum operating current.

Nominal 3C battery means 2ahx3 = 6A maximum working current.

Package Included of BMS 4S 20A LI-ION :

1 x 4S 20A Li-ion Lithium 18650 Battery BMS PCM Protection PCB Board
