Indeed there's been a LOT of e-bike battery fires, so that's why with designers and engineers in France we've spent some time designing a battery casing that efficiently contains explosions and flames, to safeguard your home, you can check it here if interested! (it's also a repairable battery, so it saves CO2 compared to a standard battery over the long term. Oh, and we're in the process of doing the UL certification right now)
I've got a tern e-bike with a Bosch motor, I love taking it on long rides. You've made a compelling case for replacing the existing battery, but what does the story look like for replacing cells in 5 years? Do I have to replace them all at once? One at a time as they fail?
Also, how swappable or parallel are the batteries? I'd love to be able to have two batteries for days when I want to ride 100 miles. My existing Bosch battery only has a ~60 mile range and I'd love to push that up.
Also, do they have a usb port on the battery for power? Running lights, charging my phone, or powering a GoPro from the bike battery would be so helpful.
