1s 3.7v 2a/3a/4.5a/6a/7.5a/9a bms 18650 li-ion lithium ba-ttery charging protection board 1/2/3/4/5/6 mos power bank cell Description: 1. Before installing the protection board, the ba-ttery must be well matched (the voltage difference between each ba-ttery must not be 0.05v, the internal resistance difference is not more than 5mq, the tolerance is less than 30mah), the smaller the ba-ttery voltage difference, the better the protection board. 2. Batteries are connected in parallel and then connected in series, and the soldering is correct (18650 ba-ttery nickel spot welding, other batteries are soldered), not screw, easy to burn out the IC protection board. 3. If it is an old ba-ttery change board, please pay attention: please confirm the ba-ttery is normal before purchasing? 4. When installing, use a multimeter to check if the tension of each string is the same? The performance failures with a difference of more than 1.0v are: running not much, starting and shutting down, charging time is short, basically the ba-ttery core problem is more. The protection board fault is as follows: the ba-ttery cannot be charged, and the ba-ttery has a voltage and cannot be discharged.
