Proper Voltage unlocks next-generation battery chemistries for the $108B+ middle-voltage market (5V–120V). Our Battery Operating System (bOS) eliminates the voltage and integration barriers that prevent chemistries like LTO, sodium-ion, and lithium-sulfur from entering mainstream applications such as e-bikes, power tools, drones, forklifts, and robotics. By decoupling battery chemistry from product design, Proper Voltage allows manufacturers to adopt the best-performing batteries regardless of voltage, without costly redesigns or long integration cycles. Our proprietary system delivers constant voltage output, adaptive charging profiles, and software-defined power optimization, enabling compact, safe, and high-performance battery systems across industrial and consumer segments.
