A business imports Teslas, strips the batteries. A single Tesla battery can be split into 10-12 household rechargeable batteries that can power lights in an apartment for up to 10 hours.

The Ukrainian power system has been damaged to the point where the power is only on for 4 hours a day in some areas.

Basic science knowledge why water is not-so-good idea on lithium-fires:

  • Lithium oxidizes the air alone and can self-ignite.
  • It is one of the few metals that can react with Nitrogen (N2) and CO2 in the air. So it will continue to react even if all oxygen is depleted from the fire.
  • Water + Lithium => Hydrogen => kaboom.

This means you have a "two-legged fire triangle" situation. The only way to stop the fire is to cool it down with something that it doesn't react with (sand), since you can't entirely remove the surrounding air. So the best option is really to just bury the thing in a sand pile.

The fact there is a ton of energy charged in a battery pack basically ensures all of the lithium will react if the battery shorts. If you ever see one puffing or rapidly heating up, you have maybe 5 seconds left to yeet the battery or the scene.
