5. Operating Instructions
5.1 Charging
- Use a dedicated LiFePO4 battery charger with appropriate voltage and current settings.
- Recommended charging voltage: 14.4V - 14.6V.
- Maximum charging current: 50A.
- Charging temperature range: -20°C to 55°C.
- Avoid charging below 0°C without a low-temperature charging function, as this can damage the battery.
5.2 Discharging
- Maximum continuous discharge current: 120A.
- Discharging temperature range: 0°C to 60°C.
- The BMS will automatically cut off power if the discharge current or temperature exceeds safe limits.
6. Maintenance
- Regular Charging: If the battery is not in regular use, it is recommended to charge it every three months to prolong its lifespan.
- Terminal Inspection: Periodically check battery terminals for corrosion or loose connections. Clean as necessary.
- Storage: Store the battery in a cool, dry place, ideally at a state of charge between 50% and 80%. Avoid extreme temperatures.
- Cleaning: Clean the battery casing with a dry cloth. Do not use solvents or abrasive cleaners.
7. Troubleshooting
If you encounter issues with your battery, refer to the following common problems and solutions. For complex issues, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected, faulty charger, BMS protection activated (over-discharge) | Check charger connection and functionality. Ensure charger is compatible. If BMS is active, try a low-current charge to reactivate. |
| No power output | Loose connections, BMS protection activated (over-discharge, over-current, short circuit), battery fully discharged | Check all cable connections. Charge the battery. If BMS is active, remove load and allow it to reset. |
| Battery overheating | Excessive load, poor ventilation, high ambient temperature | Reduce load. Ensure adequate ventilation around the battery. Operate within specified temperature ranges. BMS will shut down if temperature is too high. |
