Andrey said:While I'm waiting Cor to reply - did anyone try to replace sockets on G2 battery (power & control) or wires on G1 Leaf to attach G2 battery to G1 Leaf without swapping cells?
There's "retrofitting procedure" https://testing-public.carmd.com/Tsb/Download/126060/NTB14-059c available for G2 battery, but it assumes you buy already modded battery with right sockets and do several mechanical things outside the battery to fit it to G1.
G1 == Leaf 10-12 , G2 == Leaf 13-17
My Leaf`12 has cold climate package, if that help.
Cor has primarily done cell swaps, but he's done a lot of them. He did at least one battery exchange and didn't mention anything about wire differences, but did mention that the cover panels underneath the pack differ from G1 to G2.
Dala noted that the G1 and G2 harnesses were different. When I did my pack swap, the wiring all hooked right up, so it appears that if you order a replacement pack (or get a warranty replacement), the pack comes to wire to the car--not with adapters and wiring harnesses.
