Maintenance Tips

• Maintenance‑Free LiFePO₄ Design: Built‑in Battery Management System (BMS) protects against overcharge, deep discharge, and short circuits — no watering or routine cell checks needed.

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

• Keep Charge Healthy: Maintain charge between ~20 % and 100 % and avoid letting the battery drop below ~10 V to protect cells and extend service life.

• Inspect & Clean Terminals: Check for corrosion or loose connections regularly; clean and apply dielectric grease to ensure a reliable electrical connection.

• Secure Mounting: Ensure the battery is firmly installed to minimise vibration stress and preserve internal components.

• Temperature Awareness: Operate and store within moderate temperature ranges (LiFePO₄ performs best roughly –4 °F to 140 °F); avoid charging below ~32 °F.

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

• Avoid Lead‑Acid Jump‑Starts: Do not jump‑start with a lead‑acid battery; harmful voltage spikes may damage the BMS — use LiFePO₄‑compatible jump equipment.
