Quick Connect for Extra Batteries in truck bed?

Looking for recommendations for power connections for extra batteries in my truck bed?

I have carried 2 extra batteries in bed of truck for years now to power my inverter for 110 AC power for my CPAP. Have just run cables out thru one of the "basement" side hatches to connect. While this works, it is way past time to replace this "make shift" solution. I really like the absolute separation from the "house" system batteries, so neither system can drain the other by mistake.

I am thinking of something like the twist locks often used on marine shore power systems, but think there must be something made for 12 volt systems other than the classic cigarette lighter style plug/socket set. The ones I have seen so far just don't seem like they would take the load.

Also know i have seen threads about adding extra batteries in truck bed, but I am not coming up with the right search terms to find them. Suggestions both for plug in connections and search terms for thread or links?

Thanks.

  • We use a bunker industry one on the wrecked that is 175A for 1/0AWG gauge wire.
  • Yah, the plugs that I use, are quick connects..

    Takes a little bit of Crimping to put the wires in depending upon gauge etc.. but they're kinda kewl as I use them for the additional 8 6vt in the white boxes... and when off loading just disconnect them...
    I also have a 10' extension so I can keep camper off loaded and truck by it's side and reconnect them....

    Here's a link for the pics, you'll kinda have to browse thru them, but I had 2 batts each in the black boxes and swapped them out for 4 batts in the white boxes... Watch the gauge of wiring... I went from 2 gauge to 4/0000... It makes a big difference..

    Hope that helps...
