Installation-space checklist

  • Create a full-size cardboard template from the listed dimensions and test it inside the frame.
  • Allow extra clearance for the bag, straps, cables, connectors, and removal path.
  • Confirm the controller and charger are intended for the battery's nominal voltage.
  • Confirm continuous and peak discharge requirements against the current BMS specification before purchase.

Motor-kit matching

For a 3000W conversion kit or 5000W conversion kit, motor wattage alone does not establish compatibility. Send the controller label, connector photos, charger details, and available frame measurements for confirmation.

If you require a specific cell brand, BMS current, charger, certification document, or transport document, request confirmation for the current production batch before ordering.
