I've thought about doing this, but I envision the legal headaches and DRM that will inevitably creep into the batteries being not worth the effort. It's even possible to DRM at the cell level, and I fully expect OEMs to do that.

The bigger problem is batteries have moved into "structural elements" in the current "skateboard" designs. Removing the batteries potentially damages the foundational structure of the car and may need expensive mitigations.

You can't get DRM "at the cell level". The batteries are just simple Panasonic 18650s, adding some DRM component to each and every one of them would be cost-inefficient and would also cause a huge problem if the chip fails during warranty. The controllers are black boxes though, but you can get 3rd party units for Tesla batteries _today_. JerryRigEverything on Youtube built his own EV Hummvee on the military chassis using some Model X batteries and all 3rd party electronics. It wasn't plug and play, but perfectly doable in a semi-well stocked home garage.
