Exactly as described. I like that there were multiple ways to mount with all the hardware you would need. My 2 Group 31 lithium batteries fit just fine and unlike another brand having the hole for the battery cables on the top make perfect sense. But I’m not sure why this box is so expensive.

Great box. Much better solution than a cheap tongue storage box. Installing this on a small Brinkley and I cant use the supplied mounts. I had to fabricate my own. Space inside the a-frame is too tight. Need a mount that will allow the box to go forward enough to contact the a-frame.

by: Neil 03/07/2025

Anyone looking at this well made solid box. Needs to look at the dimensions carefully. Not all trailer tongues are the same. I new that and modified to fit. Very happy with this box

The box was perfect for my 2 batterys. The trailer didnt accommodates for batterys like that. RV manufacturer should consider building a tounge that would.

@Neil I'm glad it worked out well for you! What kind of trailer do you have the batteries on?

by: David 07/22/2019 One Year Later

I purchased this battery box and installed it almost two years ago. It is expensive, but very well worth it. I installed it to carry two 6V batteries because we do a lot of dry camping and need the durable battery power. The box looks great installed and provided excellent protection from thieves. I installed interior hold down brackets to insure the batteries do not move during travel. I can't take claim to the install, I copied someone that had previously put this install online. It works perfect and is a very clean install. I've had many people comment that the factory should have this as an option. I added an additional lock, the the lock on the right side is not adequate and is keyed to a CH751 lock that's on every trailer out there. Not secure at all. With the added lock I'm very confident my batteries are safe. Well worth it!!

This is a great product. Well built, easy to install because all the extras need were included with the box.(including battery hold-downs and mat for the bottom. Construction of the box was very good with tight rivets.
Would highly recommend this box. One of the few that hold 2 group 27 batteries.

We took a 7000 mile 82 day adventure and the box looks and operates as good as the day we installed it..

by: KCS 09/23/2017

I installed this on the front of my travel trailer to provide security for my dual batteries. Great box, very well built and looks nice. Comes with hardware and clear instructions for different mounting options. Only negative is the lock, which came keyed to the very common CH751 key. Google CH751 and you will find that everyone probably has this key who has an RV, gas cap, etc., which negates the otherwise great security the box provides. I opted to replace the lock with a higher security tubular keyed lock. The lock is easy to replace, but plan on spending an additional $20 or for a different lock. I also mounted a battery switch on the side of the box.

Excellent Product, Well built and sturdy. Processing and shipping time was slower that I would like (Ordered on June 7 didn't even ship until June 13 arrived July 2nd to Alberta Canada) But installation was a breeze and I am happy with the product!

The battery box arrived a day earlier than expected and was in great shape. Lot's of mounting options with hardware included. I have to point out that they provide first class hardware for mounting. Much better than what you would get at the big box hardware store etc. The battery box looks great, is very well built and easy to install. Exactly what i was looking for.

Fit well. Had to mound a board to the frame because it was too wide to fit in available battery brackets. Our Imagine has too much of a slope which interferes but we are pleased with how it turned out. Looks much cleaner than what we had and our propane cover now fits. Thank you. Worth the price.

Great Product. Included everything required to install on a variety of configurations. It was easy to install on top of the a-frame of my camper. The batteries fit perfectly. The pass-through hole for the battery cables seemed a bit sharp. A grommet would have been nice, but a pool noodle fit OK. The only reason for 4 stars instead of 5 is the price - it isn't cheap.

After a year the box still performs flawlessly. But the real story is the customer service. I set weight distribution bars against the locked lid and lowered the camper, breaking the locking mechanism on the lid. This was 100 my fault. I called the company to buy a new lid and they sent me one for free. The first one didnt fit, I contacted them again offering to pay to return the first lid and they sent me another lid for free and told me just to keep the first one. This was outstanding customer service. Ill give them five stars now.

It holds two 27 series renagoy batteries. It is a tight fit would be nice to have a little more length for these type of batteries.

by: Denise 06/22/2020

This is a really nice battery box and is exactly as described. Our new batteries are quite expensive, so it's really nice that this box also locks. We received it within a week but haven't installed it on our trailer yet, so I can't provide a picture.

I want to add that customer service is fantastic! A rarity these days.

It works great! The lock can be tricky, but that is the only issue weve had.

by: Michael 06/22/2021 One Year Later

Despite some confusion on the measurements that required clarification from etrailer support when I ordered, I'm very happy with this battery box. It fits two Expertpower 100AH LiPO4 batteries (slightly shorter BCI Group 31) perfectly, with enough play to get them in and out with heavy gauge wiring. The box is plenty strong enough to stand on, convenient for loading the top rack of the camper. The powder coating is a nice quality and has held up over the past year.

The product exceeded my expectations. One recommendation though. Being as it is used for batteries, you should ask the purchaser if they would like the inside of the cavity coated with a non static rubber base. As I did this myself, it prevents any positive leads from touching the case and creating aark. Use that is you would.Otherwise its is an excellent product.

Fabulous. Well made, simple to mount. Clean and tidy. I have 2 Group 27 12V batteries. Just enough room, c/w tie-down straps (included). I added an isolation switch and resettable fused overload for the power tongue unit on the exterior, along with a solar panel receptacle. All work great. Clean, tidy, and secure.

Quality is solid! Mounting hardware gives you everything you will require for a solid install. Lock works well in all conditions (below freezing). Great fit for 2 new Trojan T105’s AGM 6 V.

But, like other reviews the batteries will require some custom work to secure them in the box. The straps they provide are temporary! For the price of this item it should have something better. I used a single heavy strap that took some time and adjustments weaving it through the bottom slats and then moving the batteries accordingly till the batteries were solid.

It has been a year since my install and I am very pleased with this addition.

by: Bryan 10/31/2023 One Year Later

Not cheap, but well worth the money! I recently transferred the box to a new travel trailer and had fortunately kept all the original accessories. Given those mounting parts, the (re-)installation was a breeze.

by: Robert 07/24/2021

The battery box was very easy to install. The existing rails on my trailer were too narrow, but the battery box included all of the hardware needed for installing cross rails and the box. Looks great on the front of the camper and was a perfect fit for my two new GC2 batteries.

Do you have a question about this Battery Box?

Carrying 2 Batteries and 2 Propane Tanks on a Trailer Tongue
Propane tanks can't be store inside of an enclosed container like a toolbox. If they build enough pressure it has to vent out to open air. That is why the plastic propane tank covers you see on trailers are open at the bottom. I recommend a traditional dual tank cover, # CAM40532, for the propane tanks so you are nice and safe there. The batteries can go into a box. I recommend box # TLA7708R which is designed for batteries. It is 26-3/4 inches long, 8-3/16 inches wide, and 13 inches tall...

How to Mount 2 Batteries on A-Frame Trailer with Limited Space on Tongue
I do have a possible solution for you but unfortunately there aren't any battery boxes available that will hold two 12V batteries and fit within a 21" length and 8" width. The closest thing we have is the TorkLift PowerArmor Locking Battery Box # TLA7708R which measures 26-3/4" long x 8-3/16" wide x 13" tall and as you can see from customer pictures the batteries fit in there pretty snug. Your batteries actually don't have to be side by side so you could potentially put one inside your...

Availability Of Replacement Lid And Lock For TorkLift PowerArmor Locking Battery Box TLA7708R
Hello Bryan, thanks for reaching out. I am sorry to say that we do not offer a replacement lid or lock for the TorkLift PowerArmor Locking Battery Box # TLA7708R. We actually brought this up to TorkLift and they said the lock core is not replicable, so they don't even offer them. If your lid and lock are destroyed, the only solution I can offer is a whole new box.

TorkLift Battery Box Recommndation for 2 Renogy Core Mini 300Ah Batteries
Hey Paul, thanks for reaching out! The divider inside the TorkLift PowerArmor Locking Battery Box # TLA7700L is welded in place so while it technically can be removed, it wasn't designed with that in mind. The best option we have for you is the TorkLift # TLA7708R, but you'll need a box for each battery, and the box will be a bit roomy for the battery so I actually recommend checking around online first to see if you can find one that has more of a custom fit for you and then circling...

How to Power Enclosed Trailer Lights Off of 12V Battery
I can tell you exactly what you'll need to power your enclosed trailer's lights off of an independent 12V battery, though there isn't an adapter. You first need to mount the battery with a battery box for 12V batteries like # TLA7708R, and then use junction box # 38656 to tap into your trailer's 7-way. You will also need ring terminals # 44-5310A, and wire # 12-1-1 to run to each light, and to turn the lights on, a light switch such as the Pollak rocker switch # PK34308 or toggle switch...

Can Trailer Lights be Powered When Not Connected to Tow Vehicle
You'd need to put a battery in your trailer so that you can power the trailer lights when you aren't connected to your tow vehicle. It would be a matter of just running a power wire from the battery to the lights. You'd need to charge the battery whenever you get a chance though like with a charger # CTEK56865. If you wanted a way to power the lights and charge the battery you can use the RV Charge Panel part # PD4560K18LS8 which would plug into a wall outlet.

Best Way to Power Lights in Enclosed Trailer

Powering Interior Lights of Enclosed Trailer With 12 Volt Battery
There is a simpler way than a generator, as this would be difficult, and most generators that have a 12 volt outlet require that only to be used for battery charging. So I recommend a standalone battery on your enclosed trailer, and I'm sure you can find somebody to do it for you, yes. You'll need to utilize local resources though to find someone such as a local handyman possibly or some other individual comfortable with wiring. What you'll do is use a 12 volt battery mounted on the trailer....
