PatDes Posted September 11, 2018 Share Posted September 11, 2018 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!

RainGoat Posted September 11, 2018 Share Posted September 11, 2018 Best set up I’ve seen is by XPLOx4 https://xplorx4.shutterfly.com/437“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.” Link to comment Share on other sites More sharing options...

johann_peralta Posted September 11, 2018 Share Posted September 11, 2018 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. 1 Link to comment Share on other sites More sharing options...

01Pathmaker Posted September 11, 2018 Share Posted September 11, 2018 Hmm, I'm intrigued! How are those batteries supported and secured? Link to comment Share on other sites More sharing options...
RainGoat Posted September 12, 2018 Share Posted September 12, 2018 Are those in series, as opposed to isolated? Link to comment Share on other sites More sharing options...
dustinp Posted September 12, 2018 Share Posted September 12, 2018 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. 2 1 Link to comment Share on other sites More sharing options...

RainGoat Posted September 14, 2018 Share Posted September 14, 2018 It's on the todo list ..... but it's been on that list for a couple years. Oh yeah, I get that! 2 Link to comment Share on other sites More sharing options...
hawairish Posted September 14, 2018 Share Posted September 14, 2018 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). 1 Link to comment Share on other sites More sharing options...
