Precautions
1. Do not solder while powered .
2. The mainboard has only +/- terminals; soldering while powered carries a risk of short-circuiting due to hand tremors. Please disconnect power before soldering and connect the mainboard +/- terminals first. Solder the battery pack's negative terminal last!!! The two mainboard wires cannot balance the battery cells; cell balancing and protection functions are handled by the lithium battery protection board.
3. The chip uses a coulomb counter to calculate battery level; the initial reading may not be accurate upon first pow
