Group 31 equivalent size LIFEPO4 batteries?

[BrunoTPM]

Greetings all. Have been looking for Group 31 size equivalent Lifepo4 batteries for my motorhome. Thusfar have only found these DigiMarker batteries on Ebay with a stated capacity of 135AH each. Am curious if anyone has experience with these batteries or any other ~ 135AH rated Lifepo4 batteries. My reason for looking at these is that 2 of them should fit perfectly in the existing Kwikee slide out battery tray compartment on the MH which would maximize the capacity of the existing space by adding an extra 70AH of capacity over using the "standard" 2x100AH Lifepo4 batteries wired in parallel configuration (270AH vs 200AH).

Thank you for your consideration.

That's nearly 3 inches longer than a group 31.

"it's a smoke"? Anyway, my bad - was looking at a different DigiMarker listing that included 100, 135, and 200 AH batteries and misread the dimensions. The 135AH is indeed too long at 16" to fit in the battery tray (which is 14" x 14"). Oh well, guess I'll stick with 2 x 100AH when I upgrade. Thanks for the catch.
