French firm Gouach makes replaceable e-bike battery cells

Gouach, a French company, has developed the "Infinite Battery" for e-bikes, allowing users to easily replace individual battery cells and extend battery life. The Infinite Battery uses a durable, fireproof casing and a screwdriver-based system to swap out 18650 cells. It also features a Bluetooth-connected app for monitoring cell performance and is designed to be compatible with most e-bike brands. The company's design, which took four years to develop, uses custom-printed circuit boards and a robust casing to withstand vibration and water damage, addressing common e-bike battery issues.
