NOCO HM408 4D Commercial-Grade Battery Box

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.

It is definitely capable of doing what a battery box needs to do. Very well built!

Upgraded lead acid batteries on camper to one large lifepo4 battery. This was the perfect solution. Very solid construction but a bit on the pricey side. Top quality.

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.

Purchased 2 of these to house our 2 large 4D batteries that are used for emergency backup for our water pumps. The boxes do a pretty good job at keeping the batteries covered, but they are NOT weathertight. They're also a bit more expensive than I think they should be, but when you need it, you need it. I'd still recommend them.

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.

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.

Installed on my rv to hold a lifepo 200 ah lithium battery. It’s nice having it bolted down instead of the cheesy nylon straps that come with most other boxes

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.

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.

Seems a very good product.solid and easy to install. Not waterproof as it comes, but fine for my purposes. Looks like good value.

Seller is definitely not reputable.. good product bad seller. Pay attention to who sold and shipped by
