Maintenance Tips
  • Charge after each use using the recommended lithium/CAN charger; avoid deep discharges below ~20%
  • Do not fully drain the battery—shallow cycling improves long-term lifespan and stability
  • Store at 40–60% charge if not used for extended periods (week+ downtime)
  • Keep terminals clean and tight to ensure stable power delivery and prevent voltage drop
  • Avoid extreme temperatures—do not charge below freezing or expose to excessive heat
  • Use compatible charger only (CAN/BMS supported) to protect the built-in Battery Management System (BMS)
  • Update/monitor via Bluetooth app (if equipped) to track health, voltage, and cycle behavior
  • Disconnect during long storage and recharge every 1–2 months to maintain balance
