I've been using Lithium Ion batteries for years in electric RC. They are, as u/iamonlyoneman states, extremely vulnerable to discharging or charging too fast, or discharging or charging too much. Lion batteries should never be discharged below 20% remaining capacity. Doing so, damages the cells. Too see how violent this is, with a Lion battery consisting of just 4 cells is, check out https://www.youtube.com/watch?v=0nrsoMsEMNU. Go to the 5:50 mark in the video.

Now, I don't know how many cells those buses have, but the explosion and fireball out the side of the bus in the video is classic Lion battery explosion.

If you append &t=<seconds> to youtube links it will start where you want. I felt the action happens more around 6 mins, or 360s, so https://www.youtube.com/watch?v=0nrsoMsEMNU&t=360

I've seen single vape bats go up in people's pockets.... Scary.

Thousands. The tesla automobile uses thousands and it's just a little car. The battery in a city bus must have many times more.
