Maintenance Tips
-
Maintenance‑Free BMS Protection: Built‑in Battery Management System safeguards against overcharge, deep discharge, and short circuits — no watering or routine cell maintenance required.
-
Use a LiFePO₄‑Specific Charger: Always charge with a charger designed for LiFePO₄ (≈14.2–14.6 V) to prevent overcharging and maximise battery lifespan.
-
Maintain Healthy Charge Levels: Keep the battery charge above ~20 % and avoid deep discharges below ~10 V to extend service life.
-
Regular Terminal Care: Inspect and clean terminals periodically to prevent corrosion and ensure solid electrical contact.
-
Secure Mounting: Ensure firm battery installation to minimise vibration stress on internal components.
-
Monitor Voltage Occasionally: Use a multimeter to check voltage (~12.8–13.6 V when charged) during routine checks.
-
Storage Best Practices: If unused for long periods, store at ~50–80 % charge in a cool, dry place and disconnect to prevent parasitic drain.
-
Temperature Awareness: Operate and store within moderate temperatures; avoid extreme heat or freezing conditions to preserve battery health.
