3. Maintenance

The KEPWORTH LiFePO4 battery is designed for minimal maintenance, offering a significant advantage over traditional lead-acid batteries.

• No Daily Maintenance: Unlike lead-acid batteries, this LiFePO4 battery does not require regular watering or acid level checks.
• Temperature Management: The built-in BMS includes low-temperature cut-off protection, ensuring safe use in various environments. Avoid prolonged exposure to extreme temperatures outside the recommended operating range.
• Cleaning: Keep the battery terminals clean and free from corrosion. Use a dry cloth to wipe down the battery case as needed.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% capacity and stored in a cool, dry place.

4. Troubleshooting

The KEPWORTH LiFePO4 battery's Smart BMS is designed to prevent most common battery issues. If you experience problems, consider the following:

• No Power Output:
  • Check all cable connections to ensure they are secure and free from corrosion.
  • Verify the battery's charge level using the mobile app. If the battery is deeply discharged, the BMS may have entered protection mode.
  • Check for any fault indicators on the mobile app, which can provide specific error codes or warnings.
• Charging Issues:
  • Ensure you are using a compatible LiFePO4 charger. Lead-acid chargers are not suitable.
  • Confirm the charger is properly connected and receiving power.
  • The BMS may prevent charging if the battery temperature is too low (low-temperature cut-off). Move the battery to a warmer environment if necessary.
• Reduced Performance:
  • Check the battery's state of health and individual cell balance via the mobile app.
  • Ensure the battery is fully charged before use.

For persistent issues or advanced diagnostics, refer to the detailed information available through the Bluetooth mobile app or contact KEPWORTH customer support.
