You can easy fit 2 battery, see this:

Thanks
You're right. I got the 2009, but I guess that 120A is on the weak side for a 160A alternator. But, that being said, 160A would flow in the marine isolator only if the deep cycle battery was completely depleted, and the crank battery was full and no accessories (fuel pump, etc) was on. So I think that even with the 160A alternator and the 120A marine isolator, you'll be fine because I would be surprised it would charge at more than 120A.

I have this kit installed for a while now, and my alternator is 140A, and I depleted the deep cycle battery a few times now, and everything is still working as it was when I installed it.

Hope this helps. I guess you could find a marine isolator for more than 120A, like this one from blue sea (the same brand I got mine): https://www.bluesea.com/products/cat...Relays/ML-ACRs

This one is rated 500A, so you got plenty of room...

I used this tray: Rugged Ridge 11214.53 - Rugged Ridge Dual Battery Tray Quadratec. The installation was pretty straight forward. There were a couple steps in the instructions that could have been a little more clear.

If you read the installation instructions on the link, the following comments should make sense.

In step 5, there are four additional bolts that need to be removed to get the fuse box bracket off before the battery box can be removed in step 6.

In step 6, one of the bolts also holds the fender liner retainer. I found it on the floor under the Jeep. I was wondering what it was and where it came from.

In step 8, the fit of the tray was not perfect. It needed a little twisting and turning to line up the bolts. However, it did go in with no additional drilling or cutting.

In step 10, the evap solenoid doesn't quite want to go there. A bit of repossitioning the lines is needed to get it on the tab without kinking them.

Other than that, It went well. I did have issues with some items I've previously installed, such as my aux. fuse box being in the way. But that is no fault of Rugged Ridge.

CombatDiver Both responses are helpful. I think I'm ready to get a dual battery finally and with the plan to add some additional lights only pushes me that way.

4-LOW I know this post is about a year old but I found that the Genesis Offroad system is great! I just installed the kit and it is very high quality and totally complete! No wiring needs to be assembled! Ready to go and instructions are very complete.

It's been nearly a year since I installed my dual battery system, and I haven't had any issues so far with the stock alternator. The way the Cole Hersee solenoid works is that if the combined voltage of the two batteries is below 12.7v for more than 1 minute, the solenoid isolates the batteries. When you start your engine while the batteries are isolated, only the main battery will get charged until the main battery has maintained a voltage of at least 13.2v for a duration of 2 minutes. Then the solenoid will pair the two batteries, allowing the auxiliary battery to get charged. This design is intended to not stress the alternator with charging two drained batteries simultaneously.

CombatDiver That's unfortunate that Benchmark Designs doesn't appear to be in business anymore. There are other dual battery mount options out there and have to inquire on whether or not anyone upgrades their alternator to help maintain both batteries or is the stock alternator adequate? I just ordered a larger alternator (for other reasons) but my next planned purchase/upgrade is the dual battery on my 2009 Jeep Wrangler.
02-20-2013 02:59 PM
yomondo For those of you who are not aware, it appears based on posts I read on various forums, that Benchmark Designs has been out of business since at least last July. Their website (www.benchmarkdesigns.com) no longer exists, and the email address I had for John (john@benchmark-designs.com), which worked last April, no longer works.
10-05-2012 12:05 PM
Rob1980 I think that looks very clean. And in your application, quite practical. Well done. May do the same.

- lighted switch to turn on/off power to both 12-volt power ports
- separate 40 amp fuses and relays for each 12-volt power port
- voltmeter
- 2 amp fuse on the power line for the switch led, the relay coils and the voltmeter
- 600 watt pure sine wave power inverter connected directly to the battery with a 150 amp fuse

I figured this could really come in handy at camp, as well as provide emergency power at home.

It may make it less reliable, in the sense that obtaining a replacement alternator, if necessary, would not be as easy. For the typical application of Overland travel, you want replacement parts that are easy to source should you be stuck in a remote location.

But, on the flip side, if the actual reliability of the stock alternator is sub par, or some manufacturer boasts some kind of increased performance guarantee, then this would be worth considering.

It would make it more Robust, though. Being able to quickly recharge your depleted batteries is always a plus. But there is a trade-off to be made.
06-20-2012 08:26 PM
Vin Think of it as a hose filling a bucket with a hole in it. The hole being your accessories, the bucket your battery and the hose the alternator. Too small a hose and the bucket will empty out, too large and the water just overflows and is wasted.

Vin Well, I just got an email from the guage pod guy. Problems with manufacturing so I was refunded my money. I think I'm going to order a couple of stinger voltage gauges and mount them on my A pillar along with an led for when the batteries are connected.

However, logically, you can buy their isolator (or a similar one), and a similar box with monitoring features such as this: Amazon.com: MinnKota Trolling Motor Power Center: Sports & Outdoors

That marine battery box has the voltage monitoring system, 2 12V outputs that have circuit breakers built in (low power and high power) + access to the posts.

What else do they provide? battery terminals and cable. That's about the extent of it. So, if you wanted to use their isolator at list price of about $160. That's $160 + $70 = $230, I'm sure you can get cables and terminals for less than the remaining $470... so hence why it seems bogus to me.

Sure, other will argue about box quality. But, the extra heavy duty boxes are $40 more, still putting you over $400 ahead.

LBrito Finally received most of a tray from Benchmark for my 2012 Wrangler. They actually ended up going with the vertical stack, not the usual side by side method used for the 07-11 JK's. Of course, I'm still missing the top clamp and hardware and stuff, so can't install it. But, at least the base is here... progress... going on 4 months now, but I guess since its the first run of these, others may have better luck when they figure out all the details.

I must say, the battery tray is top notch quality. The welds are great, penetrate thoroughly through the very sturdy metal they use. The finish is also top notch. I'm actually impressed with the tray, despite the extra long wait. Looks like they're making some changes there as well, as I've been getting regular emails with status. Even if it's always, "not yet, later, we're working on it" it makes the whole wait process easier not feeling like you're possibly getting ripped off.

I'll stop by and see him tomorrow if he is working. Right now, it's raining here like a tall cow p***ing on a flat rock! I'll get some photos and info. for you. I know his is a smaller panel and keeps a trickle charge on everything. Kind of a cool setup really!

Omar Brannstrom Hi

You have great dual setups

I would like to have that to but it will cost some for the 2012 Wrangler, cost about 435$ from Benchmark designs and then add two batteries and labor.

I will probaly install it later but know I am going for a 5 days camping trip and I will run my Waeco fridge cf-40 on the main battery on the day and on the night I will run the fridge on a secondary 80A battery. I have not done this before.

I use this item



Then I put my battery in a Batterybox and couple it to the fridge. I do not use fuses here because the fridge have two fuses.

More advanced setup here that I found on Youtube
