48 V Lithium Battery Charger

This AC/DC adapter delivers a regulated 54 V to 54.6 V output at 1 A to 1.5 A for 48 V lithium battery packs used in e-bikes, electric scooters and health-care mobility devices. It accepts a universal 100 V to 240 V input at 50 Hz or 60 Hz and terminates in a 5.5 mm by 2.1 mm DC plug.

Installation and Common Issues

Connection is straightforward: plug the IEC mains lead into the adapter, insert the DC barrel into the battery charging port, then apply mains power. The 10 ft total cord length gives flexible placement. The unit includes over-current, over-voltage, short-circuit and total-power protection, so the most frequent issue is simply a mismatched barrel size or polarity on the target device.

Compatibility Check Before Ordering

Verify that your battery pack is rated for a 46.8 V nominal / 48 V system and that its charging specification calls for 54 V to 54.6 V at 1 A to 1.5 A. Confirm the charging port accepts a 5.5 mm outer diameter, 2.1 mm inner diameter barrel with centre-positive polarity. Ensure the mains socket in your region matches the supplied IEC lead or have a suitable adapter ready.

Questions about this item

How can I confirm the adapter is charging my 48V battery correctly after connecting the 5.5x2.1mm plug?

The adapter outputs 54V to 54.6V at 1A to 1.5A, matching the required charge voltage for a 48V lithium pack. A solid indicator light on the unit and a rising battery percentage on your device confirm normal operation.

What comes in the box and do I need to buy a separate mains lead?

The package includes the adapter unit with a fixed 10 ft power cord already attached. No separate mains cable is required; the 100-240VAC input works worldwide with only a local plug adapter if the socket differs.

Should I choose the 1A or 1.5A version for my 46.8V DC scooter battery?

This single model delivers 1A to 1.5A automatically based on battery demand. Use it for any 48V nominal pack (46.8V DC) that accepts a 54V-54.6V charge profile; the adapter regulates current within that range.
