Shameless plug: we're building a repairable e-bike battery where you can use your own cells at https://infinite-battery.com https://infinite-battery.com We worked on a very sturdy casing, with some specific features to release pressure and limit the fire event propagating cell to cell, you can check it here https://www.youtube.com/watch?v=v0NXXfCA2CY https://www.youtube.com/watch?v=v0NXXfCA2CY

That’s pretty cool, but it took me quite a while on my phone to figure out what I need. Been doing e-bikes since 2007. Also, the little plus next to the shop was confusing to somebody that had a beer. I think your product is hot, thanks for making something that the world needs.

Are these rated? My local bike shop won't sell anything without that specific safety rating. I forgot the exact number. I've seen that more and more common lately

  Yes! We have the EU certification and are undergoing the UL certification, it should be complete at the end of the year!

    Nice. My bike shop will only sell batteries or bikes with UL because their insurance requires it. Good luck!

I'm confused why your value proposition is that you can replace individual cells but your website also says it's recommended to replace all cells at once. Isn't that the same as the current situation where we have to buy a new battery assembly rather than replace the failed cells? > When an E-bike battery fails, 90% of the time, its just 1 or 2 cells that are dead inside or a single electronic component. But since traditional batteries are spot welded and glued, there is no chance to replace the faulty part and you need to replace the complete battery.The infinite battery is different. It uses a technology that makes it easy and safe to replace any parts, including lithium-ion cells. It doesn't require any specific tools nor knowledge. It takes less than 10 minutes. > For safety and durability, it is recommended to change all cells at once. https://infinite-battery.com/products/infinite-battery?_pos=2&_sid=270a7b26e&_ss=r&variant=50485270020386 https://infinite-battery.com/products/infinite-battery?_pos=...

  You should definitely replace all cells together - a new cell will have a different capacity and could "charge" an adjacent older cell to rebalance, causing a fire (but a good BMS won't allow that - on the other hand you'll be limited by your weakest cells despite having put some new ones in) For me the value proposition would be to avoid what happened with my previous ebike: after 3 years I wanted a new battery as the old one was on its last legs, and it wasn't produced anymore. Or what's happening with my current ebike: to avoid the same story with the battery, I am thinking of buying an extra one now while it's still produced, and it's outrageously expensive (550EUR for roughly 500Wh, which is about 7..10x the price of the cells if you are a careful buyer). (You can fit a new battery to any bike with (sometimes lots of) extra work, but esp. my previous one had a weird solution where it slid into a rail above the rear wheel and it would have been a PITA to reengineer.) So yeah if their thing works I'd consider a bike using it, on economical grounds mainly.

    Exactly! That's precisely why we designed the battery, to let people be in control of their own stuff! Our batteries have now be running for close to 3 years on shared mobility ebikes, so they are well-tested indeed! If you want more infos, send us an email at contact@gouach.com :)

I payed 1$ in July 2024 to reserve a launch-day discount. I never received any emails from Gouach after the receipt. You moved from Kickstarter to you own website. Are you actually shipping to costumers? I was super excited back then about your product and company, but the rebrandings and lack of communication made me wary.
