I ran a Power Gate on my Disco. Very easy to set up and requires no input from you. It does it all itself. Far more efficient than the usual isolators out there.

I'll take one single, top-of-the-line high quality battery over two Costco Optimas any day.

If you have things that drain the battery with the truck off like a Webasto and you live somewhere cold, it is a smart idea. You want the starting battery at 100%. It also is "safer" in case you do something stupid and drain the battery.

I'm surprise with your experience that you would write that Chris...for me the redundancies ensure (for the most part) that my expedition goes well, but more over it's a self reliance thing...knowing and doing everything for myself. Every trip is practice and refinement...the battery, solar, water heater, turbine, refer...all the simple little things to tweak. It's all part of the "Tinker". Don't need it but it's all to do with my interests...just like the D90.

Good comments. Having done the dual battery thing, with the painless kit, in my last truck I've found it to be overkill and not without issues (aka Optima quality control) and would NEVER do it again with Optimas.

I ran a fridge full time, winched plenty, and generally dogged the crap out of my single battery truck for the past year with no issues on a 2 1/2 year old Autozone gold whatever edition.

I'm all about redundancy and ensuring critical systems are backed up-if I was traveling alone I'd consider a jump box before going to a dual battery setup personally, unless it was for a protracted period where a dual battery solution would make sense.

I think it's my experiences with single battery that have made me a believer, rather than steer me away. I've run this setup in the desert in 100-degree temps with the Engel running nearly constantly all afternoon and overnight and it still started just fine.



I've also used it for three years in Park City, UT, parking it on the street in sub-zero temperatures at night and it never once let me down.


Ben Little runs the same setup. He once left his Engel 45 plugged into his D1 in his garage and went on a weeklong trip to Jamaica. When he came back, he realized what he had done and tried to start the truck....and it started right up.



I'm genuinely curious if anybody here runs an Odyssey PC2150 and has succeeded in killing this battery in the field.

These batteries are tough, tougher than most folks realize. I see no harm in carrying a foldable solar panel in my Pelican spares+tools case. When it comes to the fancy dual batteries, though, I'd rather spend the money on stuff that will truly make me self-sufficient, like a full set of recovery gear.

Dual batteries have saved my ass a couple times when the main ran dry or it was too cold or Amps not enough to turn over the Tdi fast enough. A flip of the switch and the other battery kicked in. I was running the Painless kit with a manual switch.

To caveat this, I was running dual Optimas, but never again.

I was trying to remember another reason aside from expedition related needs, don't know why this escaped me...twice I had alternator failures. One just stopped putting out and the other was cranking out 20 amps (or something like that)...so the benefit of having two is that I had plenty of reserve capacity to make it home.

Well, first things first. Had to replace original battery today. It was shot. Next step is dual hookup.

My truck was actually at the long term parking at SLC Intl. for four days. In the middle of summer.

The single Odyssey is where it's at. High quality basics. Not shitty quality overkill (dual optima - any color).

I can't figure all of the Optima hate. I personally have five in use and have never had a problem, it's the only battery I can say that about. We've even started using them in company vehicles now.

That aside, I'm far more curious about this $400 Odyssey situation. Is it really worth twice the price of a similar Interstate?

I've had 3-4 red tops (2 were good, 2 were shit), 2 yellow tops (1 & 1) and a decent blue top. The problem I have found is the trend line over time has been more crappy than good with them.

You do t need to get an optima with dual batteries. Not sure how a discussion on dual batteries turns into a discussion on battery brands.

I'd be less surprised if a discussion on batteries turned into a discussion on free climbing Mount Vesuvius. I mean, have you seen how off-topic we can manage to bring things?

Not much to Vesuvius I think, no harder than Old Rag-unless it blows up again.
