Maintenance Tips

• Maintenance‑Free LiFePO₄ with BMS: Built‑in Battery Management System eliminates watering and regular cell maintenance, protecting against overcharge, deep discharge, and short circuits.

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

• Keep Charge Healthy: Maintain battery above ~20 % and avoid discharges below ~10 V to maximise lifespan.

• Clean & Inspect Terminals: Regularly check terminals for corrosion or looseness; clean and tighten for reliable starts.

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

• Manage Temperature: Operate/store within moderate temperatures (e.g., avoid extreme cold charging).

• Long‑Term Storage: If unused, store at ~50–80 % charge in a cool, dry place and disconnect to prevent parasitic drain.

• Periodic Voltage Checks: Use a multimeter occasionally to confirm proper voltage (≈12.8–13.6 V).
