Hey guys! We're engineers/designers from France, and we've built the Ultimate DIY Battery that you can repair and refill!

It works with 90% of the bikes/motor brands on the market, so I assumed that some people here might be interested, if they got a non-functional batteries but they still want to use their e-bike?

We believe that everybody should have control about stuff they own, and we should fight against planned obsolescence!

Here are a few videos about our founder on the battery itself, why we built it, and how to assemble it:

- Presentation of the fireproof and waterproof casing: https://www.youtube.com/watch?v=EDJpt7RDbRM

Here are the juicy bits: https://docs.gouach.com

We'd love some feedback from the e-bike DIY builder community

Oh, and it's launching as a Kickstarter in September and there is an offer for early-backers here https://get.gouach.com/1 for a 25% discount on the battery!

Super cool! Any plan on making different form factors? For electrified cargo bikes, the battery is better placed bellow the cargo [0] so a squarish and flatter pack would be nicer.
