Maintenance Tips

• Keep charge levels between 20%–80% during regular use to maximize lifespan (up to ~5,000 cycles).
• For storage, maintain ~50% charge and recharge every 3–6 months to prevent deep discharge.
• Avoid charging below 0°C unless the internal low-temp protection is active; use built-in heating feature in cold conditions.
• Ensure proper ventilation and avoid installing in sealed, high-heat compartments above recommended operating range.
• Regularly inspect terminals for tightness, corrosion, or heat discoloration to ensure safe high-current performance.
• Use a compatible LiFePO₄ charger or MPPT controller with correct 24V settings to prevent over/undercharging.
• Do not exceed manufacturer-rated charge/discharge limits to protect the internal BMS and extend battery life.
• Keep battery clean and dry; wipe with a dry cloth only—avoid water or chemical cleaners.
• Check Bluetooth monitoring data periodically to track voltage, cycle count, and cell balance status.
• Secure battery firmly during RV, marine, or mobile use to prevent vibration damage to internal components.
