54.6V AC/DC Adapter for Rad Power Bikes

This 54.6V AC/DC adapter replaces the original charger for Rad Power Bikes RadRover series models including Rad Rover 5, 6, Plus, 6Plus, Step-Thru 1 and StepThru 48V lithium battery e-bikes. It accepts worldwide input voltage of 100-240VAC at 50/60Hz and comes with a 10 ft long power cord. The unit is manufactured with high-quality materials and holds FCC, CE and RoHS certifications. Safety features include over current, total power, over voltage and short circuit protection.

48V Lithium Battery Charging Capacity

The adapter delivers 54.6V output designed for 48V lithium battery packs used in the compatible Rad Power Bikes models. It provides a complete charging cycle for depleted batteries and maintains charge during storage periods. The smart chip monitors temperature and voltage to prevent overheating and overcharging. The 10 ft cord allows flexible positioning between the wall outlet and the bike's charging port.

Replaces Original Kunshan ST Smart Charger

This adapter directly replaces the Kunshan ST Smart Charger model STC-8137LD-R supplied with the listed Rad Power Bikes. The upgrade is worth it when the original charger fails, is lost or shows signs of cable wear or connector damage. It is not for riders using non-Rad Power Bikes e-bikes, different voltage battery systems or proprietary charging connectors not matching the STC-8137LD-R specification. The 12 month warranty covers manufacturing defects.
