Dual Battery Setups! Let's see them! Multiple Batteries Thread!

when it comes time I can help ya, while it’s currently a bit broken... I’ve got a solar set up and duals on my truck

 

I have a friend who's going to run 3 Group 35's, under the hood.
Using Off-Grid Engineering's Dual battery setup and their Aux tray.
He like's ice cream and has a dual fridge/freezer to keep running.

 

Disco lights and a hot tub. That's gettin it done..lmao

Currently went with a goal zero yeti 1500x when the REI 20% discount came around. Seemed like the price limit to spend before building my own. Plus I can move it around. However I still want a dual battery in the hood just did redundancy

 

And much more

 

1+1+1=3


More to come

 

Mark, you're not supposed to break the internet on the first day of the year....LMAO. Looking like a epic install.

Tons of great info here - thanks to all for your contributions!

I’m new here and want to be able to run a heated blanket (180watt) for ~8 hours. I would like to find a 150+ amp hour dual battery set-up (where I have 150+ AH) on my house battery. Anyone know of a set-up or battery I could use for this?

 

I think you'll be out on the edge of the battery world with that requirement. I'd look into a good down sleeping bag because the batteries you'll need cost thousands...lol.
I'm no expert. You're looking at 4-5 hours of use at that level and that's a big battery.

Reserve capacity is based on 25A draw. A battery with 90 minute reserve supplying a 5A blanket would last 5*1-1/2 or 7-1/2 hrs. 2 of them would do a 10A blanket for 7-1/2 hrs. 180w is 15A*12v so you’d need 3 or more batteries with 90 minute reserve capacity.

 

My wife uses one of the small 12v electric blankets to stay warm in her zero sleeping bag. It has a 30 min shutoff. She will use it four or five times a night for 30 min. We have never consumed more than 15Ah in a night. This might be a way to conserve power. 150 Ah is a lot of battery.

Very cool. That's a game changer.

I think I am going to sell my solar/dual battery setup. Wish some of you guys were closer to me to make the sale easier. First thing is to sell the 100w solar panel

Im not getting out, just going to start over with new and bigger stuff.

 

How did that goal zero work out for you?

 

I admittedly don't know much about dual batteries nor have I read this whole thread, so sorry if I'm


Anyone have experience/feedback with some of the cheaper or used lithium options? Looks like they're getting closer to the price point of the high-end AGM batteries.

Looking at making a simple dual setup with a DC to DC charger to run my fridge and maybe a couple other small things this summer while I live out of the truck for a few months.

 

Damn you posted this 6 days ago, and didn't get a like or anything...lol. You would have thought you called someone's dog a poodle. Ahahahahahha
