The cells which are in parallel will auto-balance when inserted. It's true that putting an empty cell and a full cell in, can indeed lead to a unextinguishble fire due to thermal runaway. But from the factory, cells will be very close already. They will auto balance once inserted (the parallell cells). Every single charger in existence will then balance the series cells actively on every charge cycle. So "terrible idea"? No, but maybe something to leave to the bike shop. Still better than throwing away the pack. And maybe fuses between every cell would help for protection against
(Gouach co-founder here) Exactly! The first kits are DIY for our early adopters, but we are working on an assembly pipeline in France, China and the US for our models in the coming months. Clients (B2C and B2B) will receive pre-assembled batteries
We are also looking for bike-shop owners who want to train on our batteries (it can be learned in one hour or so) to get a new revenue stream by offering to repair and assemble our batteries!
