Water-epoxy filled step-down converter for e-scooters and e-motorcycles. 12V 10A (120W) output, optional 5V 2A USB port for phone charging. Custom power ratings available.
Modern e-scooters and e-motorcycles run a 48V/60V/72V battery pack, but headlights, turn signals, horn, dashboard and GPS all need a stable 12V supply. This DC-DC converter drops the pack voltage to a clean 12V, fully potted in epoxy inside an aluminum housing so it survives rain, mud and vibration on the road.
