Precautions:
1. Never solder while energized. When soldering the main placa's + and - wires, ensure they are de-energized to prevent 99.99% of accidents.
2. The main placa only has + and -. Soldering while energized risks burns from hand tremors. Always disconnect power before soldering, connecting the main placa's + and - first. The battery pack's negative terminal must be soldered last! The motherboard's two wires cannot balance the battery; the balancing protection function resides on the lithium battery protection placa.
3. The first power-on may not pantalla 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 pantalla, but this does not affect other functions. There is no need to worry about overcharging or over-discharging.

Frequently Asked Questions
1. Protection placa wiring: For a 4S battery pack, starting from the negative terminal, the first positive terminal is B1 (4.2V for LiFePO4, 3.6V for LiFePO4). Subsequent terminals are B2 (8.4V), B3 (12.6V), and B+ (positive terminal at 16.8V). Connect the protection placa's P+ and P- to the main placa's positive terminal.
2. If the battery has charge but fails to power on after connection, first activate it by charging via the C port. All batteries require activation regardless of initial charge level.
3. After charging activation, the pantalla may show 0 or 100%. Initial power-up may not accurately reflect charge level; normal pantalla resumes after one charge/discharge cycle.
4. During use, charging stops at 80% or discharging halts at 20% due to voltage inconsistency. In severe cases, a fully charged battery may show 4.2V while others drop below 3V, rendering the entire system unusable.
Important Notes
1. Solder with power disconnected. Connect the main placa's + and - terminals first; solder the battery pack's negative terminal last.
2. The main placa's two wires cannot balance the batteries. The balancing protection function resides on the protection placa. An additional lithium battery protection placa can be added.
