It's all fun and games until one of those thousand batteries decides to go exothermic :-). This is a really amazing story and I'm impressed by the diligence and amount of effort they put into recovering and reusing all of these batteries. A couple of dendrites though, a lightning strike, there are things outside of their control that could turn the building holding this collection of batteries into a very impressive incendiary device. If you've ever seen a fire at a battery factory, it is both fascinating and scary af. People are still trying to assess the long term damage from the Moss Landing grid scale battery fire in California.

I had an 18650 flashlight and saw a video of them spontaneously turning into a flare with rocket thruster like flames and got rid of it immediately. These batteries are scary powerful when it gives off the magic smoke.

That they are, energy is energy. I was part of a Battlebots team and that is where I learned the smell of various rechargeable battery chemistries when they burned :-). We also had an exothermic adventure with a battery pack we built, fortunately it was not at an event, it was in earlier testing, but it forever gave me a healthy respect for those batteries.
