Hey Eddie! Yes, Group 31 batteries can fit in the TorkLift PowerArmor Locking Battery Box # TLA7700L. Your typical Group 31 battery measures 13" long x 6.8" wide x 9.4" high. The internal dimensions of the battery box are 31" long x 7-5/8" wide x 12-7/8". The length of the space between the side and divider is 13-3/8". See the attached photo with the full dimensions.

I do recommend measuring your batteries just to be sure. There are some slight variations between manufacturers so those battery measurements aren't absolute.

What trailer are you outfitting with the battery box?
