After we monitored many battery fires, we decided to build a casing which can sustain lithium fires for typical e-bike batteries: https://www.youtube.com/watch?v=v0NXXfCA2CY

Maybe complement that with a CT-scan of your batteries and AI to detect defects.

Would be interesting indeed! For now we don't build our own cells (the most important part for defects), in order to let our users choose their own depending on their needs (18650, 21700, brand, second-life, etc)
