Vehicle Conversions

Thank you for your inquiry. A123 Systems no longer offers any cells or battery systems for electric vehicle conversions. Our previously offered product, the Hymotion™ L5 Plug-in Conversion Module for the Toyota Prius (model years 2004-2009), has been discontinued. A123 is now focused on bringing its advanced lithium ion battery technology to market at a large scale via direct partnership with global automakers.

We thank our Hymotion customers for supporting what was the industry’s first fully certified Plug-in Conversion Modules, and we appreciate their pioneering efforts in helping demonstrate the feasibility and desirability of vehicle electrification.
