2 - 12 volt batteries in parallel

8 posts in this topic

I want to hook up 2 12 volt batteries in parallel this weekend to make sure I have enough duration. Can I just set the 2nd battery next to the rv battery and run a wire from the red to the red and one from the black to the black?

That's more or less what I did on my last Motorhome. Went all the way to Yellow stone in the spring using the heater, frig, and VCR and never lost power.

That will do it Dave.  I would use fairly thick wire, since it will be carrying half of the load current.

I bought 2 battery lead cables and I'll hook the second battery up when I get where I'm going tonight. Thanks!

I ended up having plenty of power with one battery and never needed to hook up the second one but now I have the cables and know how to do it if I need to.

I know the is a little late in the game, but I have to series 29 batteries in a box that I cobbled together from 2 battery boxes and leave them that way all season.  The few exra $$ is little compared to not have to worry about running out of juice over a weekend, especially a rainy weekend where you spend more time in the RV.

Just wire them up now so they share the load instead of having one battery that does all the work and one that sits there. They will charge and discharge together. If you want to keep them seperate, you can buy a marine battery switch that lets you disconnect one or both of the batteries as needed.

    • Glad Lavine is gone! Added nothing but slam dunks to the team. I've been out of town for the past week, so I was very delighted to hear about this trade today.
    • Not unless they ban the toothpick crossbow here too. Takes those beetles out clean.   
    • That's called seasoning. Two years ago I took a trip to Germany and we spent a few days in the black forest where I got to see some authentic old world smoke houses dating back to the 1500's and the amount of buildup on the walls, hooks, poles etc is part of what gives their hams,bacon and sausage their flavor. They use juniper wood for smoking. Absolutely delicious.  But yeah, foil, Pam and other things can help. You can also use a power washer to clean them.
    •   "We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that."   Thanks for making my nite.  
    • Also woodpeckers beat on stuff to mark their territory.   I am pretty sure that there aren't any bugs on my metal downspouts.
    • You will often discover that birds are picking very small insects from decks and other woodwork around your house;  they do the same with trees and any other structure that might hold the bugs. We see them often on our decks and they usually pick a little bit and then move on,  perhaps just checking to see if there is anything edible there. These rascals also love hummingbird or oriole nectar, sunflower seeds and of course suet in winter. We have discovered  many species that will head straight for the nectar for orioles or hummingbirds and also plunge their beaks eagerly into the grape jam bowls orioles love. Birds will eat a greater variety than you might think. We have found they do not like limburger cheese, hot dogs, or Makers Mark bourbon.  I am thankful for that.
    • And pretty soon there'll be little chinese restaurants springing up everywhere...there goes the neighborhood. 
    • I use the ball of aluminum foil, too. Works well.
    • lay them in the grass over night and wipe off in the morning.  the dew soaks in if it's moist out.  other wise lay them out and place wet towels over them for awhile..
