48v is under the motor as said - appears midway if you look at this vid of a removal \ replacement

The 12V battery is where it has always been on the RHS of the boot.
The MHEV battery (48V i think) is underneath the car.

Congratulations on the new car.
As far as I know the 12v battery is still behind the drivers side panel in the boot.
It definitely is on my 2021 D300 unless it has been moved on the later cars.
If you remove the small panel where the jack is you have to get your hand in and move a slide back at the top of the adjacent panel.
This is not a great design and is awkward to get to but once you know how it works it's ok.
I believe the 48v battery is under...

Just got a new 26 Metropolitan D350 MHEV

Does anyone know where the 12v and 48v batteries are? Noticed the boot doesn’t seem to have the removable panel where my previous MY18 12v battery was.
