Exactly. Sandy Munro has an excellent video with multiple different battery packs torn down and compared: https://www.youtube.com/watch?v=4JiDZVO9NdM

You can see that the cooling channels in the Tesla pack are these hollow undulating aluminum shapes. Can imagine they're not very cheap. Also the Tesla packs are filled with some kind of bonding foam, making repairs near impossible.

> bonding foam

Is that maybe to reduce the spread of fire? I know Tesla put a lot of work into that. Others too, I hope.
