6. Charging Instructions

The ECO-WORTHY LiFePO4 battery can be recharged using two primary methods:

6.1 Using a Battery Charger

Connect a compatible 10A-20A LiFePO4 battery charger to the battery terminals. Ensure the charger's voltage setting is between 14.4V and 14.6V. A full charge typically takes 1.5 to 3 hours.

6.2 Using a Solar Panel

Connect the battery to a solar panel array (120W-400W recommended) via an MPPT solar charge controller. Set the charging voltage on the controller to 14.4V-14.6V. A full charge with solar power typically takes 1 to 4 hours, depending on sunlight intensity and panel wattage.

7. Maintenance

• Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean as necessary.
• Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% state of charge and stored in a cool, dry place. Avoid extreme temperatures.
• Cleaning: Keep the battery clean and free from dust and debris. Use a dry cloth for cleaning.
• Avoid Deep Discharge: While LiFePO4 batteries tolerate deep discharge, it is best practice to avoid consistently discharging below 20% to maximize lifespan.

8. Troubleshooting

If you encounter issues with your ECO-WORTHY LiFePO4 battery, consider the following:

• Battery Not Charging:
  • Check charger connections and ensure it is plugged in and functioning.
  • Verify the charger is compatible with LiFePO4 batteries and its voltage settings are correct (14.4V-14.6V).
  • If using solar, check solar panel connections, charge controller settings, and sunlight availability.
• Battery Not Discharging/No Power Output:
  • Ensure all load connections are secure.
  • Check if the battery is fully charged.
  • The BMS might have activated a protection mode (e.g., over-discharge, short-circuit). Disconnect the load, wait a few minutes, and try reconnecting. If the issue persists, a small charge might be needed to reset the BMS.
• Unusual Heat or Smell:
  • Immediately disconnect the battery from all loads and chargers.
  • Contact customer support. Do not attempt to use the battery.
