Hello,
A generic recommandation is to avoid locate lead batteries under a multiplus because of H2 generation during charging.
For a lack of space, I had to put the 250 A.h 12V Gel batteries right under the multiplus.
As ATEX norm is applicable only above a 10 kW charging power, is this implantation really risky ? Do you have some experience with similar implantation (boat, van,..) ?

It is not generic, but for actual reasons. And the reasons are not as uncommon as you think.
1. Offgassing and corrosion.
You can have fans to clear the gasses to reduce this issue and charge them correctly (no excessive bulk and temp compensated charging, no over amping) to prevent any excessive gassing. (Good anyway since you want the longest lifespan you can get)
2. If batteries catch fire/explode, it affects the inverter and worse.... to get to it to switch it off is more dangerous.
There are probably other reasons those are the main 2.
I mean you can still do it. just be aware that you will need to do some other things to keep safe.
@Alexandra Thanks for your quick feedback.
Even with a charging current of C/10 (25A for 250A.h batteries = 1200W under 48V) you or Victron have a bad experience of this layout ?

Ok, thanks for your support
