Apparently you guys didn't notice that the Ebay guy selling Tesla cells
had already sold over a hundred of those battery packs.
So I doubt he got them from crashed Teslas.
To me buying a used Lithium battery makes only a little more sense than
buying a used Lead Acid battery.
I bet I could buy a bunch of used 6 volt golf cart batteries from the
golf courses around me as well..
If those battery packs were $300, it would be one thing, but at $1200
plus, I don't see that as much of a deal.

There seems to be a pretty good supply of battery packs from wrecked Tesla
Model S cars, often with fairly low mileage. People have been taking those
apart to shoehorn the modules and one or both motor drivetrains into various
other vehicles. Of course by doing that they lose the crash protection of the
aluminum battery housing. One person flipped an empty Model S battery upside
down, attached a couple of trailer spindles and fenders and a tongue to make a
little flatbed trailer.
I think it'd be fun to 'gassify' a Model S. Either convert the empty battery housing to a
fuel tank or build a tank to fit in its place, then stuff some FWD drivetrain in the
"frunk".

I do have to wonder though... if these Tesla cells were no longer usable
for a Tesla, why would anyone think they would be good in a stationary
application unless they were derated by quite a bit.
$1200 is far from free.

Here is a fairly common surplus Tesla module:

If these have have not been abused after they were removed from the
car they should last many thousands of deep cycles. They are 6s but a
7th s can be added in order to cycle them deeper on a common 24 volt
system.
My system (single, living in an RV) is close to this except I am using
two Johnson Controls modules rewired as 7s:

This technology is changing so quickly that it is hard to keep current
and reviews become stale in a month or two.
