upVolt Information

upVolt GmbH is a Swiss specialist in professional e-bike battery repair, diagnostics, and refurbishment, based in Basel. We focus on complex battery issues that cannot be addressed through standard replacement options or conventional repair shops, including BMS-related faults and component-level cell replacement. We restore and upgrade lithium-ion e-bike batteries from brands such as Bosch, Yamaha, Panasonic, Stromer, Flyer, and BionX. We also sell new and refurbished e-bike batteries. All refurbished batteries are tested and come with a two-year warranty. In addition to e-bike batteries, upVolt offers Second-Life stationary battery systems for selected home and commercial applications.
