BMW X5 F15 battery upgrade

[Mwitkowski859]

Hello, I'm new, my name is Michał and I come from Poland. I came here because I'm looking for a way to repair my car and I hope I've come to the right place
So, errors started appearing from the drive, charging and other strange things. It turned out that battery no. 3 is damaged, one cell has a voltage of 3.64v when the rest have 3.70v, looking at it you can even see that there is something wrong with it.
So I bought a Hv battery from a newer BMW, i.e. 330e. From 2021, mine is from 2016 so the warranty is already over. Somewhere on YouTube or another website I saw that they change to such cells but it didn't show how, so my question is whether anyone has done it and is able to help? Plug & play does not fit, the plugs have a different pinout although they look very similar

Are you looking to change a single module internally, or swap the entire pack?

Much more info is on the Wiki: https://openinverter.org/wiki/BMW_Hybrid_Battery_Pack
The X5 one has a different configuration to the smaller models.
