Maintenance Tips
-
Keep terminals clean: Inspect monthly for dust, corrosion, or loose connections. Wipe with a dry cloth and tighten as needed.
-
Maintain proper charging habits: Use the recommended charger only. Avoid full discharges; recharge when the battery reaches ~20–30% to extend cycle life.
-
Store in a safe environment: Keep the pack in a cool, dry area between 50°F–80°F (10°C–27°C). Avoid direct sunlight, high humidity, or freezing temperatures.
-
Balance charge regularly: Perform a full balancing charge every 1–2 months to maintain peak performance and even cell health.
-
Check BMS indicators: Monitor the Battery Management System for alerts, temperature warnings, or abnormal voltage readings.
-
Inspect cables & housing: Ensure all wiring is intact and the case is free from swelling, cracks, or impact damage.
-
Avoid high-load stress: Do not exceed recommended continuous discharge rates to prevent overheating and reduce wear.
