Peace of mind at last! Replaced main battery with a premium H7/Group 94 battery

I have the diesel, so they put the second batt in the bed Screw that, i dont want to lose bed space. Im putting the air comp/tank under the bed, so no more room for a battery

You'll know what you're looking at here better than I do.
Doesn't look like a lot real estate for something larger.

Back to the batteries...i know the aux batt wont drive a winch, pretty much a no brainer. What i was wondering was if a larger battery could fit in the space of that little motorcycle batt. Fab a tray that will take the larger size, put it where the baby batt used to be. i have not torn into to look it over, wanted opinions before i go that direction. Add an invertor, around 1000w to send power to the bed. Use the main batt for starting, switched accesories, and such.

The Aux battery, in the gas models, is in a small plastic box and held up with three bolts. It won't handle heavy loads, and isn't intended to. The space isn't large enough to do anything else with.

The batteries are paralleled together all the time, except during ESS events and the startup test, so it adds some capacity to the setup. I added a third battery that is connected through a Smart Isolator. It is paralleled in with the Main and Aux batteries, adding to overall capacity. The Smart Isolator separates it when the voltage difference increases beyond a certain level, which leaves it able to start the truck (unless you drain it with loads that are only connected to the third battery). What I installed is essentially a DIY Genesis system, except their version removes the Aux battery and mine leaves it in place.

Went wheeling today. Was worried a little, but not about the battery.

Noticed Odyssey has an Aux now: ODS-AGM14 so you can get "matched set". =D

10 Day report since I modded my Jeep:

Everything is working as expected.
My investment accounts are up.
I ran 5 miles today and scored a personal best.
My sex life is much improved.

Peace of mind is important.

All those ducks on the dash and they still needed help?

I was out with the local Jeep club. It is always an interesting mix of drivers on a ride like this. The green Jeep is a very nice ride. The street tires on it were not made for wet red clay. The son of the owner was driving, and the Jeep slid into the ditch without any input from him. I went back two weeks later. It had rained the day before, so the road was very slick. I had to use lockers to get up the hill. The ride down was tricky too. My tires packed up with mud because of the slow speed and after that I was just a passenger. ) Good thing I had "Peace of Mind."

Being around red clay all of my life, I can smell that video.
When it's just right you can barely even stand on it. Slick and stick.

I live in Edgefield.... over off Sweetwater. I don't like playing in the mud... at least not anymore.

I don't mind when roads get muddy, but I wouldn't take my Jeep to an off-road park to wallow in the mud. I hate the clean-up after.

The aux battery can't (shouldn't) be used to power a winch, but it can power a restart if the main battery gets drained powering a winch.

I removed the aux battery, replaced the main battery with a premium H7/Group 94 battery, and installed a SmartStartStop device. Ahhh! No more worries except for peace and world hunger.

Smart Stop Start - HOME BTW, send the seller an email for a possible forum discount.

No offense I just don’t know but what’s the big deal here why so worried/relieved?

I would hope that unless it's in deep water, that engine would be left running, ideally with a faster idle speed. The battery should not be the main source of power for a winch - the alternator should be contributing as much as possible, with the battery sending what can't otherwise be supplied to the winch. In all electric systems - the battery should be a buffer, or make-up pool, not a main source. If you are drawing the main battery down that far, you are deep-cycling and reducing life span.

I understand that there are cases where letting the engine run can lead to problems - but most of the time it's to get over or around things and the engine can easily be left running (and should be)

Keep it running if possible, high idle if you have the software or hardware (JSCAN or Tazer will do that. I can set idle speed with my phone, selectable RPM)
