The 54 volt 2.0 amp battery charger for Lithium electric scooters and e-bikes uses a coaxial (or "barrel") connector and has been optimized for use with Lithium-ion batteries.
For longer life of your scooter charger, please handle it carefully and store in a safe, dry location when not in use. As electric scooters are predominantly used outdoors, many times the delicate electronics of these types of electric scooter charger cannot withstand a drop on concrete or asphalt.
