There is a guy that rides the trail near me thats riding an ebike with a triangular battery pack that looks identical to one some HNer built here - He's too fast and I havent been able to stop him.
Another question for the DIY e-bik crowd, is what kind of OTS motor could one harvest, like a motor from an electric lawm mower, or edger, weed-wacker? Are there power tools where the electric motor is useable? (like how people originally used mower engines in goKarts and such?
Also, for fireproofing - mix Powdered Aerogel into a Silicon Slurry and dip the battery in that - the silicon and aerogel will make a heat sleeve thats quite fire resistant.
Thanks for your message! The battery is already designed and in production, it's running on 1500 free-floating e-bikes in France without issues since around 2 years
We're doing a Kickstarter because we're a startup so we need the upfront money to buy the parts and build the battery! We expect to ship to Kickstarter customers in November 2024!
If Kickstarter is starting in Sept, then I guess it will be another 1-2 years.
