If you like this stuff Jehu Garcia on YT does this
Those scooters in the streets get discarded/buy em in bulk and re-use the batteries for ex
Sitting congressman Massie also has a few videos on YT about buying a wrecked Model S to scavenge its battery to power his house. Not quite the same as it's just one big battery, but cool idea nonetheless.
They are rather short and show the setup more than the construction and nitty gritty, IIRC
Where can I get one? I have seen that the Chinese manufacturers who made the scooters for Bird, etc. have been taking advantage of the discarded units by selling conversion kits to turn them into normal eScooters.
From what I've seen, some people buy them from Police or city auctions. Scooters that are "towed" because they're left in an inappropriate place, often are not picked by the companies that own them, so they're left for the city to auction them or whatever.
I'm not sure where, I've just seen some of his videos where he takes apart scooters
