    I mean there are quite many fires in China started by those e-bikes but I thought it was because of bad quality.

      There are chemistries that are less volatile But they’re less energy dense as well.

      The biggest problem I see on most of the Chinese stuff is a lack of safety in the battery packs. They’re just mass-producing cells and shoving them together, It wouldn’t be very expensive to put a small battery management system on every cell. Watch each cell for voltage and temperature. Have them shut down when they’re out of safety margins

        From what i know the issue seems to be too lax safety margins in packaging, to increase density.
