Expert Answers about Battery Boxes


  • Small Vented Battery Box Recommendation For Trojan 6V Batteries
  • I recommend using the Tow-Rax Battery Box # 329-HM426 for your upgraded 6V Trojan batteries. This box has internal dimensions of 11-25/32" long, 8-27/64" wide, and 10-15/16" tall which should be more than enough space to fit one battery. You will have to use two boxes if you are using two batteries.

  • Recommended Battery Box for 2 Batteries
  • I may have a solution for you, but I'm not aware of any in floor mounted double battery boxes that aren't custom fabricated for the trailer. However, you might be able to make the TorkLift PowerArmor Locking Battery Box - 6V and 12V Lithium Batteries - Powder Coated Aluminum # TLA7700L work for your application. This is a locking battery box that can hold up to 2 batteries and you could potentially figure out a way to mount it in the floor of your trailer if needed with some fabrication. I've...

  • Recommended Battery Box for 6 Long x 2-1/2 Wide x 3-3/4 Tall Battery
  • Based off the measurements you provided, the Replacement Clamp-On Battery Box for Tekonsha Trailer Breakaway Kit # TK2018 will fit your existing breakaway battery. It's right at 5-15/16" long x 3-3/8" wide x 5" tall so it will be a tight fit, but it's the only box we have available that fits all 3 of the measurements.

  • Parts Needed To Power Interior Lights On an Enclosed Cargo Trailer
  • It looks like you already have everything you need to complete this mission. The only thing left to do would be to drill a hole or find an existing wire path into your trailer from the battery box and run the wiring to your lights. The last thing you'll want to make sure you have is some silicone # 0160297 to seal the holes and keep water out.

  • Parts Needed to Add Rechargeable Breakaway Battery to Gooseneck Trailer

  • Battery Box For 4 Optima Blue Top Marine Batteries
  • I'm assuming that you're speaking of an Optima Blue Top battery like their D34M which measures 10 inches long x 6.88 inches W x 7.8 inches tall. We do indeed offer a box that would accommodate 4 batteries of that size, with some room to spare. I'd recommend the # TLA7710R from Torklift. The box measures 58-1/2 x 7-5/8 x 12-3/4 inches, so it would accommodate up to 5 batteries of that size. Torklift doesn't offer a vent setup, but the box does slots for proper ventilation.

  • Parts Needed To Install a 12 Volt Battery To an Off Road Trailer For Lighting
  • Frist you will need a Battery # BRW34FR. This is a deep cycle battery which is designed to be drained and recharged as needed. I recommend using the TorkLift PowerArmor Solar Single Locking Battery Box # TLA7720RS to secure the battery to your off road trailer. This steel box will protect the battery and includes a small solar panel to help maintain the battery power while the trailer is unplugged. You will be able to disconnect it from the lighting using a Disconnect Switch # SE29VR which...

  • Battery Dies After Installing Curt Harness # C56208 On My Vehicle
  • There could be a few reasons that is causing your battery to drain after installing The Curt Harness # C56208. I recommend first testing to see if you have a bad converter box. While the fuse is in place, test the 4-way flat connector on the harness without any vehicle lights on using The Hook Probe Circuit Tester # PTW2993. You will need to test each pin. If you're getting a constant power at any of the pins with the vehicle lights off, then the converter box is bad and would need to be...

  • Reverse Light, Battery Charger Recommendations for Utility Trailer
  • To add two reverse lights, one on each side of the rear of the utility trailer, I recommend the Sealed, 6-1/2 inch LED Clear Oval Trailer Utility Light, 10 Diode, # BUL72CB. You will also need a rubber grommet, # a70gb, for each light, and a pigtail, # A45CB, for each light. To mount the lights, you can use Mounting Bracket # BK70BB. You would then need to wire the lights to come on with the tow vehicle reverse lights. You would need to convert the tow vehicle and trailer from 4-Way to...

This is a little larger than what you were looking for, but it would work for you. To see a product description video featuring the box I recommended, just click the provided link.

  • Recommended Circuit Breaker and Wire Gauge for Wiring 7-way Trailer Connector
  • For a circuit breaker, I recommend using a 40 amp circuit breaker, like the Pollak 40amp In-Line Circuit Breaker # 9510. The wire that runs to the battery will connect to the gold post, and the line that connects to the junction box will connect to the silver post. Usually, 10 gauge wire is used for the 12V power. I recommend using # 10-1-1. This 10 gauge wire is sold by the foot. To make connections with this wire, you will want to use 12-10 gauge wire ring terminals # DW05705-1 or 12-10...

  • Available Replacement Battery Box Lid for Pro Series 50-85-315 Break Away System with Charger
  • Unfortunately, Pro Series doesn't offer a replacement lid or even a replacement box for their # 50-85-315 trailer break away kit. Your best bet would be to replace the system. The good news is that they aren't horribly expensive, and this way you'll get a new battery so you'll be good to go for quite some time. I"ve linked to an installation video that you might find helpful.

  • Parts Needed to Add Interior/Exterior Lights and a Battery to a Trailer
  • I have attached a basic wiring schematic for a travel trailer for you to check out. We don't have anything that would be more detailed than this but you would basically just splice into the wiring on your trailer depending on how you want your exterior and interior lights to work. Aside from the wiring and lights there are a few other things you will need. The switch that you use will depend on how much draw you expect to have, which is determined by the amount of lights you have and the...

  • 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...

  • How To Power Small AC Household Electronics In A Van Without Using Solar Power Or A Generator
  • I recommend using a power inverter like the Power Inverter 1000 Watts with Three AC Receptacles # WC3720. What this will do is allow you to use your vehicle's electricity to use household appliances like the mini fridge, the box fan, and the LED lights you referenced. Realistically, you're going to need a sizeable battery bank to power all your electronics and run them on demand. My suggestion is to calculate how much energy is used in a day. Once calculated, follow the chart linked on...
