dual battery management

http://www.wranglernw.com/pc-6372-79...1993-1997.aspx

found this seems $$. Anyone have much insight to offer on wiring up for winching duties. Did a search but didnt really read much. Anyone running this setup?

I'm not running their management system, I have the Hellroaring Battery Isolator; however, I do have the tray.

It 's a great platform for any single or dual battery setup.

I've been using a surepower isolator, but that looks interesting. How long have you had it? I'm curious about longevity.

I have had the Hellroaring system for about 7-8 years - without any issues.

Why do you need a tray when dual Optimas fit in a stock NAS Defender with no mods??

I am running the National Luna Split Charge system. I like it.

What makes it cool:

1 Will not discharge main battery if accessory battery goes down.
2 Charges second battery automatically
3 No manual switch to pick witch battery gets charged.
4 Alarm to let you know if battery drains too low. And you need to start the truck. Like if you are running fridge or work lights when camping.
5 You can jump start the starter battery from the aux battery with the push of a button.
6 You can connect the batteries with a with same button for more power for winching.

I bought the parts from Expedition Outfitters. I did not buy the kit to save some money, but a probably spent the difference at NAPA and gas to get there and back like 4 times. Next time I will buy the kit.

Itís kind of expensive, but $375, but worth it so far. Kinda sounds like an addvert. Sorry

I'm running that system, Phil. I don't have the tray though. Yikes, I don't remember having paid that much for it!
No complaints with it after about 4-5 years. Came in handy a couple times, most recently when one of my batteries crapped out on me. I just flipped the switch and had a fresh one to get me going. Seems to give some extra cranking power in extreme cold when I flip the switch to run both at once.

I believe they do, but for some reason I seem to remember the drivers side of the box creating a slight incline. Are all NAS defender battery boxes the same? I don't know.

However, the tray increases the mountable surface inside the box, which might allow for larger batteries, but also supplements an extra J-hook between the batteries. Although in the picture on their [WNWPP] website I only see two. Mine has three and keeps the cross bar from warping.

I always had problems with the OEM J-hooks; they kept popping out of the floor mounts allowing the batteries to slide all over the box. It was a complete disaster. Any material that seeped into the battery box acted as 60-grit sandpaper. I replaced the OEM with some generic hooks, but the problem ensued. Serendipitously, I dropped by Wrangler NW to pick up some equipment when they asked if I would like to be the guinea pig for their tray. I installed it, provided pictures with notes and my opinion.

I went with the painless dual battery kit. Just had to replace one of the yellow top optimas, but other than that problem the system works well.

I have the TJM IBS in my D2 with dual yellow top optimas... installation was rather easy and it has worked flawlessly since I've installed it... The biggest problem though is the cost, it was quite pricey..
