I’m about to buy several Tesla model S modules from an 85kwh battery. The seller is a breaker. I am going to pick them up in person and would like to do some me basic tests before paying for them.

I have extensive practical and theoretical knowledge of electronics, but no EV experience and haven’t worked withTesla batteries before.

I’ll visit ally inspect them, but I’m guessing a full discharge-charge cycle might be too much to ask the seller to go thru.

The seller seems reputable and is known on this forum.

I just don’t want to end up with a dud module, even inadvertently.

Give them a good visual inspection and then measure the module voltage (nominal ~23V). If that looks good then if possible look at the wreck for fire damage and the documents for mileage. If all looks good then I'd say you're fine to proceed

good visual inspection = check top and bottom sides for intact fuse wire on each cell
