Auxiliary battery question

Hi,

First time posting, sorry in advance if wrong forum.

I have M550i 2018 with 2VF option, Adaptive M Suspension. I want to retrofit / change / upgrade it to 2VW, Adaptive M Suspension Professional.
Got a donor, everything is fine etc., but right now I am confused.

G30 technical papers told me that in M550i xDrive one should use 24 V steering rack.

Ok, fine. After that I find that part:


Awesome. I need third battery. Continue reading, find this picture:

And here the problems begin. There is no auxiliary battery in BMW Catalogues, that is mounted in the luggage. The only thing I found is extra battery (10 Ah), but it has to be mounted in front of vehicle, not behind. Here is a picture from catalogue -


As far as I understand, I need a part number 12. But there is literally zero information available about it.

Maybe someone had an experience and could help me with this? Thank you in advance.
