If you encounter issues with your ECO-WORTHY battery, refer to the following common troubleshooting steps:

• Battery Not Charging:
  • Check all cable connections for tightness and correct polarity.
  • Verify the charger is functioning correctly and is compatible with LiFePO4 batteries.
  • Ensure the ambient temperature is above 32°F (0°C) for charging, due to low-temperature protection.
  • Check the battery's status via the Bluetooth app for any fault codes or warnings.
• Battery Not Discharging/No Power Output:
  • Check load connections and ensure the device being powered is working correctly.
  • Verify the battery's State of Charge (SOC) using the Bluetooth app. The BMS may cut off power if the battery is over-discharged.
  • Ensure the ambient temperature is above -4°F (-20°C) for discharging.
  • Check for any overcurrent conditions that might have triggered the BMS protection. Reduce the load if necessary.
• Bluetooth Connection Issues:
  • Ensure Bluetooth is enabled on your smartphone and the app has necessary permissions.
  • Restart the app and try reconnecting.
  • Ensure you are within close proximity to the battery.
