At https://get.gouach.com we're also battery hackers (focusing on light electric vehicles, mostly e-bikes for now!) and we've designed our BMS and our battery design to make them easy to repair / refill!
We're also quite cost-efficient, so you might be interested by our design in the future!
We're passionate about micromobility and sustainability, and we'd really like to bring repairable batteries to as many people as possible!
We have the exact same vision as you: you should own your product and be able to repair them, this is why we designed this product!
Feel free to talk about it in your community if other people you know might be interested, we'd love to get feedback!
