Troubleshooting
The Miady LiFePO4 battery is equipped with an advanced Battery Management System (BMS) to prevent common issues. If you experience problems, consider the following:
- No Power Output: Check all connections for proper seating and polarity. Ensure the battery is adequately charged. The BMS may have activated due to over-discharge, over-current, or short-circuit.
- Not Charging: Verify that you are using a compatible LiFePO4 charger. Check charger connections. The BMS may prevent charging if the battery is too cold (below 0°C/32°F) or if an over-voltage condition is detected.
- Reduced Performance: Ensure the battery is fully charged. Extreme temperatures can affect performance.
- Over-Temperature Protection: The BMS will shut down the battery if it detects an unsafe operating temperature. Allow the battery to cool down before attempting to use or charge it again.
