Narrow and long LiONFe4 batteries?

I'd like to put two (or four if necessary) 12v lithium batteries in my existing bay that's set up for 4x Group 31 batteries. I'll run them in series or series/parallel to make a 24v setup. Goal is to stuff as many amp hours as I can into the space. Think I should easily be able to get 800 or so in there.

G31 batts are about 13" long, 6 3/4" wide and 9.5" tall.

Most of the lithium batts I'm seeing are somewhat wider than this.

Anyone aware of a battery that's designed to fit in these slots? Thank you. Sorry if wrong forum.

FWIW, I could not find 140Ah or 165Ah Li batteries in the Group 31 size on the Li Time website:
https://www.litime.com/search?type=product&q=G31&page=1

Here's the highest Ah capacity Group 31 size lithium battery I've been able to locate - I don't know how they pack so much Li storage capacity in that small of a battery size:

Look on Amazon. There is sometimes stock there that may not be available direct. There is also compact 300's now. Maybe 2 of them. Going for 24 volts I would also look at using 24-volt batteries. Multiple batteries in series are not as forgiving as parallel combinations.

Others have mentioned sizing ; I'm questioning " 24 volt set up " .

I'm also curious about which Class C has a coach battery bay with four group 31 batteries.

Can you post your coach , year make and model ?

Thanks for the more detailed info on your coach .

Now that the site moderators have moved your thread to the Class A forums can you post your coach year and explain why the 24 volt set up .

Last thread that mentioned 24 volt Lithium , had the OP come back saying he needed a new thermostat and fridge control board.
