About Us

Higher Wire Energy specializes in the analysis and repurposing of Second Life lithium-ion batteries. We have a proprietary technique to estimate battery state-of-health (SOH) for remaining life. We then manufacture battery assemblies for energy storage and mobility applications, and supply cells and equipment to the DIY community.
