Today we're going to review part number TLA7740. This is the TorkLift HiddenPower Under-Vehicle Battery Mount, with the Battery Box. This is a custom fit part. It is designed to fit the Dodge Ram 2500 and 3500 trucks starting in 1997. What I would recommend for you to do is go to our website, use our fit guide, put in your year and model vehicle and it will show you how it will work for your application. These parts will let you add a battery that ties into your truck's electrical charging system.
This will not include the battery. You would have to supply that yourself. This is designed to be an extension of your RV's battery when the RV is plugged into your truck and it will help provide extra battery power in your camper or RV to significantly extend the time that you can run on your 12 volt system. It is designed to work with lead acid, AGM, sealed, and gel cell batteries. This part includes everything shown here on the table. It will include this battery box.
It includes the mount itself that clamps onto your frame. It includes the mounting hardware, a nice battery hold down strap, and these 2 pieces are the quick disconnect power connectors, show you how those work in a minute here, and it comes with a nice set of detailed instructions. This nice, sturdy polymer battery box is included. As you can see it has the lid. You just push in on the tabs on the side.
Do that and then pop the lid off and you can see on the inside it's very large, has even a divider. If you need it for a large battery you just put it on the very end. If it's a little bit shorter battery you can just slide it in, helps hold it into place when it's a shorter battery. If you'll notice on the lid right here, there's a couple vents that will vent a lot of the gasses out from building up inside the battery box and also right here, these are vents also so when you put your lid on and strap everything down you get vents right here and right up at the top so you don't have any gas build up in the box itself. This mount right here, this is designed to clamp onto your frame beneath the truck. It's an easy, no drill installation and it includes the necessary mounting hardware right here and, again, the battery strap to hold the battery box down.
Basically your battery box would go right in there with the battery and this would be all up under the truck out of the way. Then on the quick disconnect power connectors, it even makes it even easier to install and remove the battery, because what you end up doing is these will come with connectors that you'll connect to your wiring and it will allow you to, one would be to the battery, the other would be to your wiring on the vehicle, and what you end up doing is just line these up, just like that, and you push it together and it will make your connection. Then, if you need to remove the battery, you can just disconnect them very easily. Very simple to do. These parts are made in the USA and they do come with a lifetime warranty. That should do it for the review on part number TLA7740, the TorkLift HiddenPower Under-Vehicle Battery Mount with the Battery Box. .

Installed this about a year ago and have not had any issues with it. It works as advertised! Its not "easy" to install or remove with my current set up and heavy AGM battery. I likely have to many heavy lines going into the box and then connected a fuse box/distribution box on the outside of the box. I have been off road and have not damaged it at all! Great product to keep the "house Battery" out of the bed of my truck and attached low and out of the way! Trying to figure out if I can mount a second one!! 619125
Review from a similar TorkLift Hidden Power in Battery Boxes
The bracket is solid, but the mounting/securing of the plastic box to the bracket leaves a bit to be desired. It does protect the battery well from the elements, but it does not secure the battery down well. If you wanted to spend more money, you could get a battery box from the Offroad manufacturers that fits within the plastic box and bolt it down, which would be more secure. I’m going to be modifying the bracket and box so that I can attach a ratchet strap in place of the provided strap to make it secure as possible without breaking the bank. Eventually I might take some all thread and clamp down a bar across the top of the battery, similar to some older OEM battery securing mechanisms. 637084
