6. Maintenance

6.1 Battery Management System (BMS)

The Redodo LiFePO4 battery is equipped with a 100A BMS, which provides comprehensive protection to ensure enhanced safety and longevity. The BMS protects against:

• Over-current
• Over-charge
• Over-discharge
• Short-circuits
• High-temperature

This robust protection contributes to the battery's impressive lifespan of 4000+ cycles and over 10 years of use.

6.2 General Care

• Keep the battery terminals clean and free from corrosion.
• Store the battery in a cool, dry place when not in use for extended periods.
• Avoid exposing the battery to extreme temperatures.
• Regularly inspect the battery and connections for any signs of damage or wear.

7. Troubleshooting

If you encounter issues with your Redodo LiFePO4 battery, consider the following common troubleshooting steps:

• No Power Output: Check all cable connections to ensure they are secure and properly tightened. Verify that the battery is adequately charged. The BMS may have activated a protection mode (e.g., over-discharge) if the voltage is too low.
• Charging Issues: Ensure your charger is specifically designed for LiFePO4 batteries and matches the battery's voltage requirements. Check the charger's connections and power supply. If the battery is very cold, it may not accept a charge; allow it to warm up to an appropriate temperature.
• System Overload: If the battery suddenly stops providing power during use, the BMS may have activated over-current protection. Reduce the load on the battery and attempt to reconnect.
• Unusual Heat: If the battery feels excessively hot, immediately disconnect it from all loads and charging sources. This could indicate an internal issue or an external short circuit.

For persistent issues or complex problems, refer to the detailed troubleshooting section in the full user manual or contact Redodo customer support.
