Maintenance Tips
- Keep all terminals, busbars, and cable connections tight, clean, and corrosion-free to ensure stable high-current performance.
- Use a compatible LiFePO4 charger or inverter-charger with correct 24V lithium charging profiles to protect battery health.
- Regularly monitor system voltage, state of charge (SOC), and load to avoid deep discharge and extend cycle life.
- Maintain proper ventilation and keep the battery bank in a dry, temperature-stable environment away from direct heat or moisture.
- Avoid charging below freezing temperatures unless the system includes low-temperature protection or heating features.
- Inspect interconnect cables and fuses periodically for heat damage, wear, or loose fittings, especially under heavy loads.
- Ensure batteries are evenly balanced by allowing periodic full charge cycles when recommended by the manufacturer.
- Keep firmware (if using smart BMS monitoring) updated and check BMS alerts for over-voltage, under-voltage, or temperature warnings.
