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

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.
3) 1C rated battery, 2000mah equals 2ah*1=2A max working current.
4) 3C rated battery means 2ahx3=6A Max working current.
