Maintenance Tips
  • Maintenance‑Free LiFePO₄ with BMS: Built‑in Battery Management System protects against overcharging, over‑discharge, and shorts — no watering or routine cell checks needed.

  • Use a LiFePO₄‑Compatible Charger: When charging externally, use a charger intended for LiFePO₄ (~14.2–14.6 V) to avoid stress and maximise lifespan.

  • Avoid Deep Discharging: Recharge before the state of charge drops below ~20% to preserve battery health.

  • Clean & Inspect Terminals: Periodically check for corrosion or loose connections and clean terminals for reliable starts every time.

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

  • Manage Temperatures: Operate and store within a moderate temperature range; extreme heat or cold can affect performance and life.

  • Storage Best Practice: For vehicles not used regularly, keep the battery at ~50–80% charge and disconnect to prevent parasitic drain.
