Built-in Protection Functions 1. **Reverse Polarity Protection**: Prevents damage when positive and negative terminals are connected reversely. 2. **Short Circuit Protection**: Automatically cuts off output in case of short circuit. 3. **Over-temperature Protection**: Automatically reduces output power or shuts down when overheating. 4. **Over-current Protection**: Limits output current to protect charger and battery. 5. **Over-voltage Protection**: Prevents excessive charging voltage. 6. **Full Charge Cut-off**: Automatically stops charging once the battery is fully charged.

Charging Operation Steps 1. Confirm your battery is **4S 12V LiFePO4 battery pack** with built-in BMS protection board. DO NOT use for other battery chemistries. 2. Check the connector polarity. Connect the charger output plug/clips to your battery correctly: Red = Positive(+), Black = Negative(-). 3. Plug the AC power cord into the charger first, then plug the AC plug into the wall mains socket. 4. Charging starts automatically. - Charging indicator ON: Charging in progress - Full indicator ON: Battery fully charged, charging finished 5. After charging completes: Unplug the AC mains power first, then disconnect the output connector from battery.
