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

You get what you pay for sometimes more and sometimes less. In this instance poor noco plastic box - unstable plastic continues to cure or shrink resulting in non parallel side panels and smaller openings than officially advertised etc. Over priced - not pleased with this Noco product. Ultra thin. disappointment - should have returned the junk but made the mistake of giving it a chance.

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.

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.

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.

It does its job well enough, but the gaskets it comes with to ‘seal’ the lid are awful. They are plastic (instead of rubber or silicone), and disintegrate within a year.

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.

The battery box is sturdy though the plastic was bowed in slightly in the middle. I am glad that it has a place to secure the box in each corner though I plan to run a strap over the top as well. There are two small holes in the lid, likely for ventilation, but I prefer to keep the moisture out of the box. My lifepo4 battery does not need the ventilation so I filled the holes with black rtv. I also used the packaging that came with the battery to prevent any movement from occurring. It is a perfect fit with the packaging.
