Wiring precautions:
1. Installing the protective board requires a certain amount of
technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad
position to the total negative terminal of the battery (the B- wire
should be soldered to a short and thick wire) and solder the wired
terminal to the battery pack first, and then insert the protective
plate.
3. The connection between the battery terminal B- and the
protection board terminal B- should be short and thick, otherwise
it will cause the protection board to charge and discharge in
advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
