Style Name: Dual 6V Verified Purchase
Well made except it just doesn't have the bottom and top vent ports that are needed for RV batteries. I purchased this to house 2 Trojan T-105 batteries in our Toy Hauler trailer. I used a hole saw to cut out the top and bottom vent ports on the original single battery box, then a smaller hole saw to cut corresponding holes in this box. I then attached the ports using rivets with a layer of silicone between surfaces to seal them. Now the bottom vent port sits in the same hole in the trailer floor and the top port connects to the original vent hose that goes out the side of the trailer.

I replaced my trailers single battery and battery box with two 6 volt golf cart batteries. It has worked great. I had to make minor modifications to get this to fit. I had to move the propane tanks a few inches to allow for the extra space of this larger battery box. Although this trailer box is intended for marine applications, it works great for RV trailer as well. I installed this on a 1972 Silver Streak Continental 28 foot trailer. The box has great openings on the lid which open downward so that the batteries are protected from rain, snow, dust, and dirt, and you can run your electrical wires wherever needed for your particular application. This top lid also has two screw down handles which really ensure things stay put. Due to the expense of batteries, I would also recommend you install steel straps or bars around this box to keep it secure from theft and to help keep it secure to your trailer or boat. There are four installation screw holes in the bottom of each corner to also keep this securely in place. This is a well designed battery box from NOCO. I have had very good experiences with NOCO battery chargers and maintainers, and now their battery boxes as well. This box is great for allowing one to run two 6 volt golf cart batteries in series so that the net result voltage is 12 volts.

First of all, It's a great battery box that fulfilled my needs. I mounted it on the tongue of an enclosed race trailer. Although I couldn't use the mounting holes I simply drilled through the bottom where I needed too and used fender washers. The 2 things I wish it had are a locking lid and a way to close off the unused wire holes. I understand this box was really not intended for the purpose I'm using it for so other than that it's all good

This box is heavy duty and deep, perfect for our two 6 volt RV batteries. It seemed pricey but when it arrived I was so glad I ordered it.

Style Name: Dual L16 Verified Purchase
I have 2 of these enclosures for my (4) L16 AGM batteries in my home battery backup system. They are very durable. The cable holes accommodate my #2/0 wire for my inverter/charger. The enclosure is not completely sealed, I would not use it indoors with a flooded lead acid battery, unless modified to be properly sealed and vented.
Only issue I have had is the top being difficult to close with my 12" long #2/0 battery interconnect cables. I think shorter cables about 8" long would solve the problem.

Style Name: Dual L16 Verified Purchase
Used this to mount two L16H-AC Trojan batteries on the tongue of my toy hauler. Very nice and sturdy, easy to mount. I always use a primary battery fuse, it was a little tricky to mount a 100A thermal breaker directly on the terminals. Beware that it is not air tight, so an installation in an enclosed space would release hydrogen gas and create a hazard. Not a hazard outside on the tongue.
