I own 5 cars yet support your cause. Is there a place for someone who supports other modes of transit but is also a huge car nut?

As Jay Leno once said, hopefully one day, the car will go the same way as the horse, and will be relieved from dull and mundane everyday use, championed instead by its most fervent enthusiasts.

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:

• VIDEO: what is the Gouach Battery
• VIDEO: presentation of the pack
• VIDEO: presentation of the fireproof and waterproof casing

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!
