Maintenance Tips

• Maintenance‑Free BMS Design: Built‑in Battery Management System protects against overcharging, deep discharge, and shorts — no watering or routine cell checks like lead‑acid.

• Use a LiFePO₄‑Compatible Charger: Always charge with a charger made for LiFePO₄ chemistry (~14.2–14.6 V) to prevent overcharging and extend battery life.

• Avoid Deep Discharge: Keep the battery charge above ~20 % and avoid letting it fall below ~10 V to maximise service life.

• Inspect & Clean Terminals: Check for corrosion or loose connections regularly; clean terminal posts and use dielectric grease for secure contact.

• Secure Installation: Ensure the battery is mounted firmly to minimise vibration stress on internal components.

• Temperature Awareness: Operate and store within moderate temperature ranges; avoid charging below ~32 °F (~0 °C).

• Long‑Term Storage: If unused for extended periods, keep ~50–80 % charge and disconnect to prevent parasitic drain.

• Monitor BMS Alerts: Allow the Battery Management System to reset if it shuts down due to protection triggers before attempting to recharge.
