OK,
Buy a new "cheap" Tesla - about $35,800 right now.
Remove the battery pack.... ;-)
You guys on the west coast make it sound like you have Tesla's sitting
on the side of the road with "$500 or best offer" sale signs.
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.
