Maintenance Tips  

• Charge correctly: Use a compatible LiFePO₄ charger only; avoid lead-acid modes or overcharging above 43.2V.
• Avoid deep discharge: Recharge before dropping below ~20–30% to preserve long-term capacity.
• Temperature care: Charge between 0°C–55°C; avoid charging in freezing conditions unless the built-in heating system is active.
• Storage best practice: Store at ~50–70% charge in a cool, dry place if unused for long periods.
• Keep terminals clean: Check M8 terminals regularly for corrosion, looseness, or salt buildup (marine use).
• Monitor via Bluetooth: Use the built-in BMS app to track voltage, temperature, cycle health, and prevent imbalance issues.
• Avoid overloads: Stay within 100A continuous discharge limit to prevent BMS cutoff.
• Rinse & protect (marine use): Wipe exterior after saltwater exposure; maintain IP67 integrity by avoiding pressure washing ports.
• Regular use helps: Periodic cycling prevents long-term storage imbalance in LiFePO₄ cells.
