7. Troubleshooting

If you encounter issues with your ExpertPower LiFePO4 battery, consider the following:

• No Power Output: Check all connections for tightness and corrosion. Ensure the battery is adequately charged. Verify that the BMS has not activated a protection mode (e.g., due to over-discharge or over-current) using the Bluetooth app.
• Charging Issues: Confirm that your charger is compatible with LiFePO4 batteries and is functioning correctly. Check charging cables and connections. Ensure the ambient temperature is within the recommended charging range.
• Bluetooth Connectivity Problems: Ensure Bluetooth is enabled on your device and the battery is within range. Restart the app or your device if necessary.
• Reduced Performance: Over time, battery capacity may slightly decrease. Ensure the battery is not consistently over-discharged or exposed to extreme conditions.

For persistent issues, refer to the detailed specifications or contact ExpertPower customer support.
