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!
