Precautions:

1. Never solder while energized. When soldering the main board’s + and – wires, ensure these wires are de-energized to prevent 99.99% of accidents.

2. The main board only has + and – terminals. Soldering while energized risks burns from hand tremors. Always disconnect power before soldering, connecting the main board’s + and – first. The battery pack’s negative terminal must be soldered last! The main board’s two wires cannot balance the battery; the balancing protection function resides on the lithium battery protection board.

3. The first power-on may not display the battery level accurately; it will recover after a few cycles.

4. The default capacity is 500mAh per cell. Significant variations may cause inaccurate battery level display, but this does not affect other functions. There is no need to worry about overcharging or over-discharging.
