Fits 2, LiTime LiFePO4 Smart Batteries
I'm replacing the 6v golf cart batteries on my camping trailer with 2 x 12v LiTime LiFePO4 smart batteries. These are just a bit larger than Group 24 or 27 batteries, so it's hard to find either a single or double battery box to fit them. I wasn't sure this would fit either, but since Amazon's return policy is great, I took a chance, thinking I might need to stand the batteries on end to fit them in. Upon arrival, the batteries fit perfectly end-to-end with a couple of small foam spacers to keep them from sliding around. What's more, the case is also wide enough that I can move the shunt from my battery monitor from it's separate box into the main battery case. This simplifies my setup a lot and removes excess clutter from the front of the trailer. Boxes look very robust, lid screws on securely, no ugly battery box straps to deal with, and I think I'll be very pleased with the purchase.

Good sturdy box
2nd one of these I got to hold a 40D battery in my RV. Easy to install, sturdy top, plenty of cable room.

great battery box
I use this in my tear drop trailer to hold a 200ah LiFePO4 battery. Works great. Easy to secure in place. Would buy it again.

Solid battery box, beneficial upgrade
I had to upgrade my super small battery box for my camper with this one so that I could use my newly upgraded large battery. This battery box is very durable and strong, the walls are thick and the product is solid. It has a nice appearance with my camper, and it fits well.

Sturdy with a capital S
The box is thick and robust. Whatever you put in it will be well protected. I bought mine to hold my 200amp lithium battery on the front of my travel trailer. It's a tight fit but will work. The only negative is it lacks a simple way to lock the lid. But I won't subtract a star for that.
