Years ago when we started the project we thought we were being smart using stock production car parts in our build such that the junk yards would be full for years with spare parts. In reality we missed a consideration. What we did not count on was the solar market buying the junked battery packs from the yards in bulk. After a couple of months we found a replacement BMS, and after 4+ months we decided to bite the bullet and buy two brand new modules from Nissan. We tested several modules in our current pack, between 3v-4.2v they take on 56Ah. Thus our pack is in very good condition. The used modules for sale online seem to be at a max 70%SOH. As we understand how the pack would function, the entire pack would drop to the 70%SOH performance level with installation of these modules. So rather than reduce the performance of the pack significantly from day one we have opted to pay ridiculous funds to Nissan for two new modules.
TAKE TWO.
One of the new modules is already bloated, reject.
OK, now we have two good modules out of the four available in the U.S. One came from New Jersey, the other from Illinois. The bad one was from Maryland, our last hope would have been in California...
We hope that over Thanksgiving break we can get the wiring error determined, the packs installed, and maybe the car back rolling!
