You may be able to benefit from our failure. We used a 9000mile 2013 Nissan leaf pack to build our car. In June we pulled the pack as two of the modules had failed. We tested a couple of modules and found we were still in the 90% SOH range. The best used modules we could find were in the high 60% range. Adding these to our pack would have effectively cut our range by a 1/3. We just last week found one new module in NJ for and arm, and another in MD for a leg through the dealer network. Turns out the MD one was SWOLLEN and will be going back. We found supposedly the second to last in the USA yesterday in Chicago. What we have learned is that we should have got a couple of spares when we got the originals to ensure replacements as if this happens again to us it looks like we will need to replace the entire pack. i.e. even if you do not need the blister pack, get it for spares. We thought we were doing great to use commercially available modules that would be available for years...
