My concern with re-using wrecked packs is not knowing what kind of internal damage they might have ESPECIALLY after reading about this golf cart battery fire/explosion on the Escapees forums:

Definitely not something to take lightly, and without some technical understanding.

If I were to do it:

1. The pack would be fully disassembled, down to it's smallest module size.

2. Each module would be checked to see if it's in-spec in terms of voltage, and for signs of physical damage.

3. Each module would be charged stand-alone, outdoors, to full capacity, and then drained to 20%

4. Modules would be assembled to achieve target voltage / current, and then charged as a pack, outdoors, and then drained, as a pack to 20%

5. A BMS with over discharge, over charge and temperature monitoring would be employed.

Only then would I be comfortable putting pack built from a wreck into service.

If it is a leaf battery a lot of those checks can be done with Leaf Spy software and the obd port. Lots of leaf owners do this with their leafs. (not me, I just drive the heck out of it :) )
