1: Please wire strictly according to the wiring diagram,can not short circuit!
2: After the wire is connected, it needs to be charged first then output.
3: When connecting 4 batteries in series, please make sure that the voltage of each battery is the same. If not, please full each battery separately and use it in series. In the discharge test, the battery with the fastest voltage drop was the bad battery.
Do not mix good and bad batteries together! The capacity/internal resistance of the 4 batteries is as close as possible (2 good batteries + 2 bad battery = 4 bad batteries).
