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)
