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.

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.

Fast etrailer delivery. The box is extremely well made, high quality mounting hardware included. Easy to install, good directions. Design of the lid allows install in a tight location.

Could not ask for anything better from seller. Contact and shipping was first rate. Ordered one day and it was delivered two days later. Install was by the book as soon as I pulled my head out. Looks great and feel a lot safer.

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.

Review from a similar PowerArmor in Battery Boxes


I’m not impressed, this box is very expensive for what you get! First off, this fancy ‘secure’ box comes with the most basic lock that has extremely generic keys! A tubular lock is needed at the very least. Secondly, as the diamond plate is simply pop-riveted into place there was a large gap that I had to caulk as it would’ve let excess rain/moisture/dirt right into the box. I also had to re-drill the holes in the divider so it actually fit. On the good side, Powder coating is nice, lid seems solid, and e-trailer’s delivery was super fast! Shipping it into Canada was cheaper than purchasing from local RV vendors by more than $200… but this box is still very overpriced! I was in a rush this time, but for the price I could’ve bought all the materials and a small welding unit… Just some food for thought! Also, definitely don’t waste your money on the solar version, the tiny panel wouldn’t come close to keeping 4 to 5 GC2 batteries charged!

Thank you for letting us help you today. With the PowerArmor Battery boxes being designed for automotive lead-acid batteries, they are not water tight. Lead-acid batteries need to be vented to keep fumes from building up inside the box. As far as water getting inside the box there are slots in the bottom of the box for mounting, so any water that gets inside would drain naturally.

Review from a similar PowerArmor in Battery Boxes


This custom battery box addition looks like it was original to the trailer. The diamond metal matches perfectly with our Outdoors RV travel trailer. It is beautiful and perfectly designed. We did discover, unfortunately, that you must be careful with sharp turns, as the corner of the battery box is able to touch/dent/crack the rear taillamp of our Dodge Ram truck on a tight turn. The replacement lamp was relatively inexpensive and easy to install ourselves. Now we know how far to turn and to watch for this in the future. LOVE the box and how secure it keeps the batteries!!

Review from a similar PowerArmor in Battery Boxes


I leave my trailer in a remote location for six months of the year. I wanted the security of a lockable box for my batteries. I purchased the TorkLift PowerArmor Solar Locking Battery Box, converted my trailer to two x 6 volt batteries and added the solar panel. Super great choice. The batteries are trickle charged when I am away and box is super secure! Installation was easy. I had to purchase two extension arms for the box as my spot was behind my gas tanks. Called the team a etrailer and they quickly the additional hardware. I also called about solar charging of the batteries. This team is super knowledgable and offered a tremendous amount of information. This has been a great purchase and I have shared with my fellow campers too! Thanks guys for all the help!


Comments
It has been a super product. I think that the only weak link is the connector from the panel to the outside of the box. That is clearly showing UV damage. I do not know if any of your customers ever used the external female plug to the battery for anything else - I did and found the box is wired backwards based on RED being hot! I did check all my wiring to make sure red is to positive inside the box. Since I dry camp, I bring in 30-40 gallons of water per trip. I purchased a 12v self priming water pump and proceeded to connect the same type trailer connector to my pump Did not want to have to keep opening the box up. To my surprise the pump ran backwards. I used the alligator clips to the battery and the pump ran correctly. I determined that female connector on the outside of the box is not wired with red to the positive. I simply reversed my connection and the pump runs correctly now. Great product. Wish you had a ventilated security box for my honda e2000 generator.

At this time we do not offer an enclosed security box for your Honda e2000 generator at this time.

Review from a similar PowerArmor in Battery Boxes


No more wanting to take the travel trailer out and go to find the batteries dead or even worse stolen. I would absolutely say this lockable battery box with solar panel is a great product and very well built. Even before I installed this on my travel trailer the sun was hitting the solar panel at an angle in the garage and I tested the for voltage, (19 volts DC). I was totally sold on the ability of this solar panel, the solar panel was in my garage and not in direct sunlight. Although I could have installed this box with all supplied parts and hardware I took it a step further, cut some angle iron and welded the angle iron mounts on top of the frame. Turned out real nice and looks real nice too! This box looks like it should have come with my travel trailer manufacturer. Very happy costumer, feel secure about the ability to lock up my batteries and they stay charged too!


Comments
Thank you for following up on your products. We are very happy with our purchase and so glad that your products are such good quality. Have had many camping friends ask questions about were we purchased our secure battery box and we just had to share! As we travel around the state parks and camp grounds we always have people asking us were we got this setup, hope this helped your sales go up. We just know everyone is as happy as we are and thank you again for such a nice product!

Review from a similar PowerArmor in Battery Boxes


Nice battery box, I have four golf cart 6V batteries, and they fit perfectly. If you use the divider there is room for other equipment like a charge controller, etc. I am using this for a small solar power system. I had to work with the lock a little to make it work, I shortened the strike lever and bent a little bit but no big deal. Nice product.

The item showed up and the top would not slide into place and lock. I had to bend the welded C channels so it would work properly. It was not a huge deal, but it was a bummer I had to do this on such an expensive product.


Comments
Thank you for your review. I am glad that you fixed your item but this product has a limited lifetime warranty so if something happens to your item in shipping, this would have been covered.

I had been looking for a quality propane tank lock and this one is exactly as described. The lock is robust and allows you to lock two propane tanks and a regulator with the lock and built in key.

Great, heavy duty battery box with solar panel. I bought it about one year ago and it is still rugged and wiring well. The heavy duty locks and construction keep My batteries stare and charged by the sun.

Review from a similar PowerArmor in Battery Boxes


I have 4 Trojan T-105 6 volt batteries installed in this box. They fit nicely with a little room at each end, ( as it is designed for up to 5 ). I installed a couple of 2x2 aluminum angles to keep the batteries in position. The box is great, keeps my batteries securely anchored and safely stored out of sight. The box sizing was a perfect fit behind my propane tanks. The lock on the box was a little sticky but I ground the tab down a bit and it works fine now. The aluminum checker plate has not oxidized and the black wrinkle finish is tough and durable. Just don't try to wax it. I'm still trying to get the wax out of the little grooves :) 5 stars all the way.

Review from a similar PowerArmor in Battery Boxes


Earlier this year I decided to upgrade my DC Power systems on my travel trailer. The project included two roof mounted 160Watt solar panels, 6volt golf cart batteries, and a 2kW AC Inverter. I chose the Torklift 5 battery security box because I needed to fit in 4 @ 6 volt deep cycle golf cart batteries. With this box, which can contain up to 5 batteries, I installed 4 golf cart batteries, and used the divider to create a separate section for my power junction and switch box. This was extra convenient because I wanted a secure space to install the source / disconnect switch and 300Amp fuse for my 2,000 watt inverter. (See pictures) I had plenty of room to install an A/B/Both/Off marine switch, a common bus, and the 300 amp class T fuse block, safely segregated from the battery compartment. The solar keeps the batteries topped off at all times, and the inverter will power everything in the coach except the Air Conditioning (which in Alaska I never use). The Battery box fit perfectly between the twin propane tanks and the forward bulkhead of the coatch body. The securely locking cabinet will prevent theft of the batteries while in storage. Love it !

TorkLift's battery box has exceeded my expectations. It houses four 100AH lithium-ion batteries that are maintained by the attached solar panel. The box was installed in minutes on my trailer and locks keeping the batteries safe from theft. The quality of the material and the workmanship are first rate. By using some additional solar panels I can now boon dock for much longer periods of time.

This battery box worked out perfectly. Greg was awesome in helping me figure what I needed. Just to help clarify, the box does come with a 8amp power regulator. It's hidden under the solar panel and you have to remove the panel from the lid to see it, otherwise you would not know it's there.
