5. Maintenance
5.1 Charging
Always use a charger specifically designed for LiFePO4 batteries with appropriate voltage and current ratings. Avoid overcharging or undercharging, as the BMS will protect against these conditions, but consistent proper charging extends battery life.
5.2 Storage
For long-term storage, charge the battery to approximately 50% of its capacity. Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures. Periodically check the battery's state of charge during storage and recharge if necessary.
5.3 Temperature Considerations
The battery features a low-temperature cut-off function to prevent damage in cold conditions. It will stop charging below 0°C (32°F) and stop discharging below -20°C (-4°F). Ensure the battery operates within its specified temperature ranges for optimal performance and longevity.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging. | Charger not connected, charger malfunction, temperature too low. | Check charger connection and functionality. Ensure ambient temperature is above 0°C (32°F). |
| No power output. | Battery discharged, BMS protection activated (over-discharge, over-current, short-circuit), loose connections. | Recharge battery. Check the Wattcycle APP for BMS status. Inspect all wiring connections. |
| Bluetooth connection issues. | Out of range, Bluetooth disabled, app malfunction. | Ensure device is within 300ft range. Verify Bluetooth is enabled. Restart the app or device. |
| Battery feels warm during operation. | Normal operation under heavy load, insufficient ventilation. | Some warmth is normal. Ensure adequate airflow around the battery. If excessively hot, disconnect and contact support. |
