Show HN: Sustainable and repairable e-bike battery (that's also fireproof)

Hey everyone!

I’m Maël, one of the co-founders of Gouach, and I’m so excited to introduce the Infinite Battery, that we believe is a revolutionary step in e-bike battery design!

Traditional e-bike batteries fail often just for one or two faulty cells, but the entire battery has to be replaced because they're glued and welded together. We’ve developed the Infinite Battery to fix this. It’s fully repairable in under 10 minutes with no special tools required. We’ve made sure it’s compatible with major e-bike brands, and our universal mounting system works with most bikes. Plus, it’s waterproof, fireproof, and built to last.

Our team has been testing these batteries in real-world conditions with free-floating e-bikes in France since 2022, and the feedback has been incredible. We’ve added tons of features—like a smart BMS with sensors, a rugged aluminum casing, and more—all with the goal of creating the safest and most durable battery on the market.

We can’t wait for you to check it out and help bring a new standard of repairability to the e-bike world!

I'm a regular lurker here, so feel free to ask any question, and me or someone from the team will do his or her best to answer!

Cheers, Maël Co-founder @ Gouach
