2023 22023 25FBT International Battery Box dimensions

Can anyone tell me the battery box dimensions on the 2023 22023 25FBT International?

I just bought a 2023 25FBT International and can't measure mine because it has not yet arrived.

Why do I want to know this? Due to a $2K markup, I am not going to have the dealer supply me with batteries.

So this leaves me to ask you all for recommendations on what I should get - The 2023 trailers all autodetect battery type so I could drop anything in there that will physically fit. I intend to do most (but not all) camping without hookups - so want the most amp hours, and at the same time just want to drop them in without any mods, So I want some that will fit into the existing box and connect up with the existing wires. ie: Drop in.

I see that the Battle Born 100Ah 12V GC2 LiFePO4 are recommended by AirStream - but was wondering if I could squeeze more Ah into the existing box?

My battery box measures: 13 x 15 x 10.75. There is also a lip on the box for the lid that limits the size a little so the opening is about 12.5 x 14.5

I haven't seen any Lithium batteries that are >200Ah that will fit better than the 2 GC2 batteries or some of the other brands.
