I think if you are putting it in your 4Runner you need to look at this:

But if it were me I would call these guys:

They really ae the Toyota experts in the country.

What about for an '04? Same setup? WOuld it work for it as well with the bottle jack out? I was hoping to use two yellow top Optimas. Do you think it would work with this type setup?[/QUOTE]
My buddy has an '04. I'll take a look and see if the fitment is the same relative to the surrounding interference. I suggest you contact Mike Aedo at [mike@aedo.net] and ask him if the tray is any different for the '04.
If the tray fits then, yes, you could put two yellow tops in there. I put one red and one yellow Optima in mine and still had room to mount the solenoid for the two of them.

If you're not in a rush to get yours installed, Overland Journal will be testing dual-battery management systems in the winter issue.

What is the benefit of going with a dual setup as opposed to one *large* single? Apparently a class 31 Odysey fits in the factory LR tray?
Is it just in case something kills the primary, you have a backup to start the vehicle? Just curious, if it's just about the reserve capacity, it seems everything I read states dual batteries are a hassle?
For a backup just to crank the truck, what about a small Odysey? I have a small one in my trackday cary. About 1/4 size of your typical car battery, but puts out plenty of amps. Just no capacity. Might be good as a backup in tight spaces.

Right, I took a smart pill and called and spoke to John Lee at EE. He enlightened me about the 31, and I have already ordered it. I was thinking of a B/U scenario for startup, but JL said that I should not experience a total drain with the 31, unless I let it sit for many days. He said he has never experienced any problems running the 31 on expeditions. These guys are great, and I trust them completely. My expedition are close, but still a few years off. Once I am an empty nester, I will be taking a few longer trips, for now I am set with a couple of days of camping or so.:bike_rider:

I started with an Optima blue top as a replacement for the original battery at the recommendation of John Lee. It fits great in the Disco's huge battery well. Plus, it has extra terminals that are convenient for auxilliaries.
Eventually I decided to go with the dual battery set up for the sake of having a backup. Something about having redundant systems that just makes sense to me when I'm out in the middle of BFE. Old military training I guess.
I haven't found it to be a "hassle" (to quote Rob) having dual batteries. I find that having an automatic battery management system and battery monitors is quite handy. It's reassuring to know that I can manually connect the two, replace one with the other or even transfer one to another truck if I need to.
All that being said, a large marine battery like a 31 works well in a Disco. The same cannot be said for some more recent model Rovers where low battery voltage from something as inane as running your fridge can shutdown your ECU and prevent you from even starting the truck.

Which Odyssey are you suggesting as the backup, specifically? I would like to throw one in just in case....consdiering hey have a shelf life as long as 10 years, this is a great idea.
Hi folks
I'm curious if anyone here has the National Luna dual battery management setup and some feedbacks please. I've ran several Optima batteries, yellow/yellow, red/yellow, red/blue and now red/red and I use the Painless Wiring setup. My latest issue is that my aux red top drained and when I start the Rover and flip the switch to charge both batteries - the voltage on the aux side did not "spike" up. I've had my setup for a couple of years now and I just don't feel 100% sure of its reliablity. First I thought the yellow top was the culprit then my blue top toast on me and now this. I've checked for short/draw in the system but can't seemed to oint the finger yet. Anyone running the Hellroaring and why is this a better system. Thanks.

National Luna ...
Well I went with the National Luna setup via Sierra Expedition for redundancy, and from what I have read it seems like a very reliable system.
I am currently installing this with twin 1500 Odyssey Batteries. I run a Webasto heater and eventually a Engel 45 fridge. Also to get the max from the Warn 9.5 XP dual seemed to be the way to go.
When I'm done on this build :

I will report back.

I ordered the setup from Sierra Expedition and paid the advertised price.
