Dual battery setup

[PatDes]

I'm looking to do a dual battery set up on my 2004 pathfinder. I wonder if anyone here has done it and how they positioned the batteries. Photos would be appreciated!

Best set up I’ve seen is by XPLOx4

“I installed dual batteries for emergency starting purposes, since I occasionally drained the main battery during long camping trips while using my 12v refrigerator. The main battery is an X2Power SLI34AGMDPM battery, and the emergency starting battery is a compact Odyssey PC680. The batteries are kept in isolation using a Hellroaring battery isolator, except when using a dash-mounted switch to connect the two together.”

give this a read for sure

I had 2 at one point. I turned the original 90*, moved the fuse box a tiny bit back, removed the battery clamp, slid the original as far as i could to the passenger side, then fit the second one beside it. Had to extend the ground cable.

Thank you! I would love a picture, if you have one!

Hmm, I'm intrigued! How are those batteries supported and secured?

[RainGoat]

Are those in series, as opposed to isolated?

[dustinp]

They are isolated I have them triggered when the car is on to open up. I also added a switch just in case the main went dead. They are supported by a metal plate on the bottom. I don't want to talk about how they are secured at the moment haha. It's on the todo list to secure it properly, but it's been on that list for a couple years.

Oh yeah, I get that!

That Expedition Portal link...it's an okay read, but I wouldn't go past the first few pages unless you want to be suffocated by electrical theory and conversations rendered useless after people deleted their posts.  I've seen some better links.  I found this one especially useful for the basics: http://www.outbackcrossing.com.au/FourWheelDrive/Basic_Dual_Battery_System.shtml

 

This post had a lot of pics: 

 

I dig @XPLORx4's setup, too.  That's probably the route I'll probably take eventually, though I may run my camping accessories off it instead of having it solely for jumpstarts (but I would have a switch for that purpose, too).
