I'ts not a simple swap, this involves making 6 new T- wiring looms because the newer battery packs use only one CSC and only 3 NTC's per cell pack instead of 2 CSC's and 6 NTC's.
the dimensions of the packs are the same, the new packs arer around 0,9 kg heavier because of their higher energy density.....
I reset some self-learning adaptation values and will have to see on a longer term how this translates in a higher mileage but al least the packs are 6,5 years younger so that's already worth the money without a doubt....

Wow, great work! How much did it all cost for the batteries alone?
Any update on range increase? You should get a good 50% extra, 24-30 miles ish total (in comfort, not e-drive).
