by:

Sturdy and holding up well on the front of the trailer.




by:

Worked well holding size 24, then size 31 replacement. One of the clips holding the lid on doesn’t release easily. Should be able to push in with both hands to release quickly. Takes some manipulation to remove.




by:

Box works as intended but I used sheet metal screws and fender washers to mount it more securely. The plastic footmen loops are good enough to keep the top on




by:

Not yet installed.
Box cracked during
storage,but I will repair it.




by:

I ended up installing 2 extra batteries in my camper so I never used this for a battery box, but it makes a great tool box!




by:

Installed with a new DC converter, AGM battery, and new DC outlets and charging station in our popup camper. Perfect fit with the battery and space and once I figured out the strap, I like how it secures the lid and box. Can't wait for our next boondocking adventure! As always, etrailer is the best. Easily changed my order to substitute for the out-of-stock charging station.




by:

Worked perfect for my trailer!




by:

Do not change a thing.




by:

The tray worked great




by:

Everything showed up as advertised,great shape,and works great.Thanks for excellent service.

Works great for the larger class batteries. It has a little divider piece so the smaller batterie aren't bouncing around.

Exactly what the doctor ordered to get power to my 12000lb winch on my custom trailer.

Box is sturdy and has a nice feature to custom fit your battery. Realized I could have gotten the same product for 1/2 price from AutoZone .. but the product does what I wanted.

After a year the box is still going strong. I do t keep it covered from the summer sun or winter snow and it has weathered well.

The battery box came quickly and it was just what I needed . I love etrailer because of their thorough description of each product compared to that other online retailer.

  • Internal Length of Snap-Top Battery Box with Strap for Group 24 to Group 31 Batteries
    In regards to the Snap-Top Battery Box with Strap for Group 24 to Group 31 Batteries part # 329-HM318BKS, the internal length is 14" and the external length is 14.2" which you can see in the photos below.

  • Recommended Battery Box For Tongue Of Trailer
    We have an option that will work exactly how you are wanting. I recommend the Snap-Top Battery Box with Strap for Group 24 to Group 31 Batteries - Vented # 329-HM318BKS which can be mounted to the tongue of your trailer and would be perfect for carrying an additional battery. I included a video of the # 329-HM318BKS for you to take a look at.

  • Availability of Battery Box for 2001 Ford F-150 with 5-1/2 Foot Bed
    I do have an option for you, however the TorkLift Hidden Power Under-Vehicle Battery Mount # TLA7729 you referenced is only designed to mount to the underside of certain model year Ford Vans. It has not been tested with your 2001 Ford F-150 and there is a good chance there won't be enough space along the frame rail to mount the unit. There is not a custom under-vehicle battery mount available for your truck but you can take a look at the more universal design of the NOCO Battery Box #...

  • Can the Deka Battery Isolator DW08770 Be Used On a Boat
    Yes, the Deka Battery Isolator part # DW08770 can be used on a boat to separate the starter and auxiliary battery but you would need to mount it in a location that is least likely to get wet, like in a battery box, the NOCO Snap-Top Battery Box with Strap part # 329-HM318BKS.

  • Will a Car Battery Fit in Curt Battery Box for Breakaway Kits C52090
    In all likelihood the Curt battery box # C52090 will not be large enough to hold a car battery. This box is only 5-7/8" long x 3-1/2" wide x 5-3/8" tall which is the size of the average 5 amp breakaway battery for a trailer. We do have larger boxes such as # 329-HM318BKS. Inside it is 14" long x 7-1/8" wide x 9-5/8" deep. If you can tell me the size of your battery and where you want to mount it I can make other recommendations.

  • Powered Trailer Jack Blows Fuse on 2017 Chevy Suburban
    Assuming you had the jack powered directly from the 7-way trailer connector, rather than a trailer mounted battery, you have blown the 12-volt feed fuse to the trailer connector. GM refers to this as 'Trailer Battery' and it's in location 67 in the fuse box under the hood, as shown in the provided diagram. I'd also recommend you check the power supply wire for the jack, as sometimes there will be an inline fuse. For best results, I'd recommend installing a battery on the trailer. You can...

  • How Does Battery Get Added to Trailer for Powering Interior Lights
    Best way would be to run the power wire of your trailer connector to the positive post of a trailer battery and then running the power wire of all of the accessories to the positive post of the battery. That way it's drawing from either source but the battery still gets a maintenance charge when connected to tow vehicle. Basically it's a matter of installing a battery box so that you can securely install a battery and then running the 12 volt acc circuit of your 7-way to the positive post...

  • How To Install a Battery On a Trailer for Use with Electric Jack
    I have attached a photo for you that shows how a 7-way trailer connector is wired. If you take a look at the trailer side trailer connector you will see a terminal labeled "12V Power". If you were to run a wire part # 10-1-1 (per foot) from this terminal on the 7-way trailer connector to the positive terminal on the battery that would then provide a maintenance charge while the trailer is attached and the vehicle is running or the key is in the ACC position. This will depend on how the...

  • Battery, Battery Box and Charger Recommendation for a Superwinch Tiger Shark Series Off-Road Winch
    I'd go with a quality "starting battery" for your winch. The nicest one you can afford and keep it charged up between uses. We do not carry those batteries, but we do carry battery boxes. The Deka Battery Box part # 329-HM318BKS would probably work well for you, but you would have to compare it's inner dimensions to the external dimensions of your battery. This box has inner dimensions of 13-3/8" long x 7" wide x 8" deep. For a good charger I would recommend the CTEK MULTI US 7002 12-Volt...

  • Can Master Lock Electric Trailer Winch # 2953AT Be Powered from SUVs 12V Accessory Outlet
    Electric winches such as the Master Lock Electric Trailer Winch # 2953AT can pull significant current when under load. This particular winch draws 20 amps at its rated capacity. An SUV's accessory 12V power outlet cannot deliver the required current to operate a winch at full capacity. These outlets are intended for lower-current-demand items like emergency lights or small air compressors. Optimum winch operation requires a higher-capacity connection directly to a battery, preferably to...

  • Adding a Battery to a Snowmobile Trailer for Interior Trailer Lights
    Start with mounting a battery. Since the trailer is enclosed, it would be a good idea to mount it on the trailer frame using a battery box like # 329-HM318BKS. Next, you will need to have the right kind of connectors on the truck and trailer. I would use a 7-Way RV style if you do not already have them on the truck and trailer. There is a 12 volt circuit on a 7-Way. You can run a wire from the 12 volt circuit on the trailer side connector to the positive battery terminal. The battery should...

  • Recommended Battery for Bulldog Winch # 15019
    For the Bulldog Winch Trailer Winch - Wire Rope - Roller Fairlead - 4,400 lbs # BDW15019 the battery requirements are simply 12V and exceeding the max power draw of the winch at 340 amps. The recommended battery size from the manufacturer for maximum power is 650 Cold Cranking Amps. Since you will be putting the battery directly next to the winch, I recommend the NOCO Battery Box with Strap # 329-HM318BKS or the Tow-Rax Battery Box - Polished Aluminum # TWSP12BP.

  • Adding a Second Trailer Battery to Power Trailer Accessory Lights
    While you can add a second battery to power lights, this is going to require a second, 12 volt auxiliary battery; this is the same concept you were thinking of but a breakaway system battery isn't going to have the power or amp hours needed for your lights. Doing this is fairly simple as you will just need to start by mounting Battery Box # 329-HM318BKS to your trailer frame with some self-tapping screws and washers, like you can see in the linked video review of this box. Then to charge...

    It really power your observation camera from your 2018 Toyota Highlander, the first thing you will need is a 7-way with a 12 volt charge, so start by installing the 7-Way RV Upgrade Kit # ETBC7L, which is generally used for wireless brake controller compatibility but is perfect for what you're looking to do. You'll also need the Bargman 7-Pole Round Connector w/ Hardware - Trailer End # 54-67-525 for your trailer and can cap off the unused wires on both of the 7-way connectors and you...

  • How to use 12V Power Jack With Trailer That Doesnt Have a Battery
    Since your trailer doesn't have a battery I am under the assumption that it has a 4-Way flat connection. Rather than installing a battery, battery box, and a 7-way with charge line circuit you can attach the 7-Way Molded Trailer Wire Connector # H20044 to the Stromberg Carlson Electric Trailer Jack # JET-5000 and use the vehicle battery to operate the jack. To do this simply connect the black wire of the connector to the black wire of the jack. The white wire of the connector will need...

  • Adding Interior Lights to Trailer and Keep Battery Charged
    The best way to get interior lights in your trailer is to have a dedicated 12 volt battery, and battery box like # 329-HM318BKS mounted to the trailer. This gives you the power needed while you're not hooked to your truck. For lights I recommend LEDs because they require much less power, and last longer than incandescent bulbs. Which lights I recommend depends on how many you want to add and the way you want to mount them. You'll need wire # 12-1-1 and ring terminals # 44-5310A for each...

  • Upgrading Trailer Battery on Horse Trailer from SLA1055 to a Standard 12V Battery Size
    It appears you are using a breakaway style battery for your trailer power. If this is correct, you will still need the breakaway battery separate by law, but you can absolutely add a larger battery (often deep cycle) to your trailer. To add that larger standard 12V trailer battery, you will need a location to house it. If you don't already have a location, then I recommend the NOCO Snap-Top Battery Box with Strap for Group 24 to Group 31 Batteries - Vented # 329-HM318BKS. Then you will...

To do so you would use a battery box like you mentioned, the NOCO Snap-Top Battery Box with Strap for Group 24 to Group 31 Batteries - Vented # 329-HM318BKS, but you would also need a charger for that battery.
