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.

@Marduk73 water cannot extinguish electrical fires. I remember you had to use a fire extinguisher with CO2 or foam (can't remember exactly which, but if it was burried I think it's the former)

You are right for fires involving electronics, cables and alike. However, the German Accident Insurance Institution (DGUV) actually recommends water for extinguishing burning lithium ion batteries and forbids the use of anything other (CO2, anti metal fire powder, ABC powder, BC powder,... )
If an EV is burning the fire fighters extingush the fire with water and as soon as the EV is cooled enough to allow some handling it is put into a container filled with water for a quite long time.

wtf? why don't they allow this? after all it is a matter of life and death!

"Forbids" here is more like "are not to be used", as against recommendations, rather than illegal.

Perhaps, as the medium shall fulfil either of both tasks, keeping oxygen out and cooling, the others are not effective enough in cooling.

Unless I'm reading it wrong, that pertains to small LI batteries for household objects, like laptops and wireless screwdrivers, ie. stuff that can plausibly fit into a basin full of water. not sure it would apply to a whole car.

See this site (unfortunately in German, but some pictures) on how it is done with EVs.
