Maintenance Tips
-
Use a LiFePO4-Compatible Charger – Ensure the charger is designed for LiFePO4 batteries (14.2V–14.6V) to avoid overcharging.
-
Charge Management – Keep the battery between 20% and 80% charge for longer lifespan. Avoid discharges below 20%.
-
Inspect Terminals – Regularly clean and check battery terminals for corrosion and ensure a secure connection.
-
Temperature Considerations – Avoid extreme temperatures; store and use in environments between 32°F and 113°F (0°C to 45°C).
-
Minimize Deep Discharges – LiFePO4 batteries handle deep cycles, but frequent discharges below 20% can reduce longevity.
-
Built-in BMS Protection – Rely on the Battery Management System (BMS) to prevent overvoltage, undervoltage, and overheating.
-
Proper Storage – If storing for extended periods, keep the battery at ~50% charge in a cool, dry place.
