Maintenance Tips
- Monitor battery status regularly via Bluetooth app; check voltage, SOC, temperature, and cycle health to ensure optimal performance.
- Keep terminals clean, dry, and tightly secured; inspect every 3–6 months for corrosion or loose connections.
- Avoid discharging below the recommended low-voltage cutoff to maximize lifespan and protect the BMS.
- Ensure proper charging using a compatible LiFePO4 charger or solar charge controller with correct 12V settings.
- Operate and store within recommended temperature ranges; use the built-in heater function in cold climates before charging below freezing.
- Maintain good ventilation and avoid enclosing the battery in airtight compartments without airflow.
- Check for physical damage, swelling, or abnormal heat during regular inspections and discontinue use if detected.
- Periodically verify firmware/app connectivity and update if manufacturer updates are available.
- Secure battery firmly in place for RV, marine, or mobile applications to prevent vibration damage.
- Do not parallel or series-connect beyond manufacturer specifications (12V system limits only unless explicitly approved).
