Installed on nose of car hauler to store a marine battery. Works great and looks factory. Battery used to operate tongue jack and lights. Paired with redarc charge unit, fused disconnect, and 120v charger. Charges while towing and when connected to AC. Would be 5 stars if the battery mounting was better. Comes with a fabric strap.

Used on my boat trailer to secure the battery for a power winch install. This is the way to go over hand winching.

Item arrived with large scratches on the lid, and was missing mounting parts. RV dealer was able to make it work without the mounting hardware. Lithium battery fits inside the TorkLift battery box. I wanted a box with a lock so I can keep the expensive battery secure. This box serves that purpose.

Built with excellent materials, powder coat, brackets, and the installation hardware, looks great. However the provided key lock uses a key that is used on all travel trailer, so it looks visually secure but the key to open is everywhere that makes the box pretty useless. It would also be nice if a plug could be provided to plug the 2” hole if not used.

The box is very nice but it suffers from on FATAL FLAW, namely, that it isn't secure against anybody but the most casual thief. Why? Because it is keyed with the infamous CH751 key, which anybody can buy offline for a couple of bucks.
This isn't etrailer's fault, of course--they only sell the thing and didn't design it. But now I gotta figure out a way to add security to an already costly box.
I must say that service from etrailer was great--the box arrived at my house just 3 days after I ordered it.

This TorkLift PowerArmor Single Locking Battery Box is the most ingeniously designed battery lock-box ever - the lid comes completely off with just a slight adjustment toward the narrow end. No worries about battery-access, even in the tightest spot, so long as there's about an inch front/back of the box to accommodate the lid's front lip & the back "tabs/hinges" - simply shift the lid slightly toward the narrow end, open it and lift it off. This allows for complete and open access to the entire inside of the box. The cable access hole is dead-center just below the lid on the back/hinged side. I might have to make access holes to the left and right of that hole in order to get my seemingly shorter cables attached - shortest route would be best for my configuration, anyway. If that's the case, I'll have to figure out how to plug the hole, but that's the least of my concerns - securing my RV battery is paramount and this box is sure to do the job - and look mighty stylish at the same time.

Nice secure box for the battery. I did change out the lock to a barrel lock which matched my other locks on my trailer. But the box itself is really nice and had enough room for the batter and the shunt for my battery monitor.

I'm using this as a battery box for my custom truck. I built a bracket to mount it to the inside of the frame. The box is ok. Upon opening the lid I found a couple of deep scratches on the back of one of the diamond plate walls. I get it... it's inside the box and out of view, but it still bothers me a little. The lid is finicky. When I rotate it down to close it, I have to "jiggle and wiggle" it before it is able to slide into the close (locking) position. My last gripe (so far) is the huge sticker with the TorkLift logo that's stuck to the front of the box. I paid a fortune for this thing, and there's no way I'm going to advertise for them on top of it all. It took a lot of effort (heat, goo gone, etc) to get that thing off. That alone is what motivated me to come on to review it. I also believe it is over-priced for what you get. After seeing it, holding it, and adapting it for my requirements... I should have just built one myself.

- Will the TorkLift PowerArmor Single Locking Battery Box Fit a Brinkley model I275?Hey Winston, congrats on the new trailer. I don't know the dimensions of the battery box that comes with a 2026 Brinkley model I275. We don't have access to that information. I can tell you that the TorkLift PowerArmor Single Locking Battery Box item # TLA7720R measures 17-3/4" Long x 8-3/16" Wide x 11-1/4" Tall. TorkLift makes quite a few different battery boxes in this style. If you could tell me what size the one is on your trailer and what type of battery it is, lithium or a standard...
view full answer... - Will TorkLift PowerArmor Battery Box Fit In Same Space As Plastic Battery BoxHey Mike! Those plastic battery boxes vary in size, even for the same battery, so you will have to measure to see if the TorkLift PowerArmor # TLA7720R will fit the same footprint. The outside dimensions are 17-3/4" long x 8-3/16" wide x 11-3/8" tall. Compare that to what you have now to see if modification will be required. Did you upgrade your converter as well? I would double check to make sure it is lithium compatible. 2021-2022 is is around the time they started switching those at...
view full answer... - TorkLift PowerArmor Locking Battery Box Dimensions- Will It Fit Patriot Power 1800 GeneratorWhile I don't know what the dimensions on the Patriot Power Generator 1800, I can tell you that the TorkLift PowerArmor Single Locking Battery Box # TLA7720R is 17-3/4" Long x 8-3/16" Wide x 11-1/4" Tall. If your generator is under that size, this locking battery box will do the job. I've also attached the link to the rest of our locking trailer battery boxes that fit 12v batteries in case that doesn't work for your generator. You'll find that we've got a pretty good variation of sizes...
view full answer... - How Wide Is TorkLift PowerArmor Battery Box BaseHi Chris; that 8-3/16" wide measurement listed on the TorkLift PowerArmor # TLA7720R is actually the width of the base, not the lid. Unfortunately, that means this battery box is too wide to fit in your available space. We don't have any others that feature a lock and the aluminum diamond plate construction that would fit there either. The only option would be to modify where you mount it or mount it in another location.
view full answer... - Battery Box Options for Dual Group 31 BatteriesThe TorkLift PowerArmor Solar Locking Battery Box part # TLA7700LS is not wide enough to fit two group 31 batteries. Group 31 batteries are 13" long by 6.72" wide by 9.44" tall. The only option that's big enough is the Commercial Grade Battery Box # 329-HM485. This is designed for dual 8D batteries which are a bit bigger, but it will work well with your two group 31 batteries. If you're set on a solar powered battery box, the only other option is to use a TorkLift PowerArmor battery box,...
view full answer... - How to Power Winch at Rear of Chevy SilveradoWhat you would normally do for a front-mounted winch is use an auxiliary battery and Isolator # PK5231201 between your Silverado's battery and the aux battery but the issue, as you mentioned, is the distance to the rear of your truck. The best option then is going to be using a battery box mounted on your truck and wired to your winch. You should use the TorkLift PowerArmor Single Locking Battery Box # TLA7720R because it has an access hole for wiring and locks to keep your battery protected. Using...

- Availability of Mounting Brackets for TorkLift TLA 7712 Battery Box Torklift doesn't sell the mounting brackets as a separate item, but they are included with the # TLA7720R battery box, however it isn't absolutely necessary to use the brackets. As you can see in the linked video for the # TLA7720R battery box, we simply installed it directly into the trailer A-frame using existing holes in the underside of the box.
view full answer... - Recommended Single Locking Battery Box for a Lithium BatteryIt will Doug! It's going to be a tight fit but your Epoch Lithium Battery Model 12300AH Battery will indeed fit inside the TorkLift PowerArmor Single Locking Battery Box item # TLA7720R. The issue you're going to run into is the narrow gap at the top to run your wires through. The pictures you saw were on a box that had been modified to have the wires come out through the side. I do not have a comparable alternative to suggest that doesn't require modification. The TorkLift PowerArmor...
view full answer... - Would TorkLift PowerArmor Single Locking Battery Box be Easily StolenThe lid of the TorkLift PowerArmor Single Locking Battery Box # TLA7720R is locking and then the box itself bolts to where it installs using included brackets and hardware. The box and the contents of it would not be easily stolen based on that. I attached a review video for more info on this box for you to check out as well.
view full answer... - How to Add Battery to Utility Trailer to Power LightsTo protect the battery and prevent theft you'd want to use a battery box like the Torklift part # TLA7720R which you can mount on the a-frame or in the trailer. Then from there you'd want to run the 12 volt accessory circuit of your 7-way to the positive post with 10 gauge wire like # 10-1-1 and run your lights directly from the battery terminals. We also have a version of this box with a solar panel with part # TLA7720RS.
view full answer... - Battery Box with Solar Charger for Boat Trailer Equipped with StrongArm Electric WinchThe Dutton-Lainson StrongArm Electric Marine Winches come in varying capacities and all are shown on the linked page. For example, the 4K model # DL25200 will draw 40-amps and the 9K model # DL25215 will draw 70-amps current so the right battery box and charger will depend on which one you own and what size battery you'll be using to power it. For a locking battery box with integrated 10-watt solar charger the TorkLift PowerArmor item you referenced # TLA7720RS is a good choice if its...

view full answer... - Will TorkLift PowerArmor Locking Battery Box Fit Group 34 BatteryYes, a Group 34 battery typically measures 10-1/4 inches long by 6-13/16 inches wide by 7-7/8 inches tall and the TorkLift PowerArmor battery box, part # TLA7720R, has internal dimensions of 16-3/4 inches long by 9-3/4 inches wide by 11-1/2 inches tall. According to TorkLift this box is guaranteed to fit all Group 24 to Group 35 batteries.
