• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% state of charge. Store in a cool, dry place away from direct sunlight and extreme temperatures.
• Self-Discharge: LiFePO4 batteries have a very low self-discharge rate, reducing the need for frequent recharging during storage.

7. Troubleshooting

• Battery Not Charging:
  • Ensure the charger is properly connected to both the battery and a working AC outlet.
  • Check if the charger's indicator lights are functioning correctly.
  • Verify the battery is not in a low voltage protection state (the 0V charge function of the charger should address this).
  • Check for any tripped circuit breakers or blown fuses in your system.
• Bluetooth App Connectivity Issues:
  • Ensure Bluetooth is enabled on your smartphone.
  • Make sure you are within range of the battery.
  • Restart the app and/or your phone.
  • Ensure the battery is powered on.
• Reduced Performance/Range:
  • Verify the battery is fully charged.
