New Genesis Offroad battery products for the ESS system

[bd100]

Both versions keep the ESS system.

One version relocates the ESS battery up top to make it easy to change.

Another version replaces the ESS with a group 25 battery, and the starter with another group 25, both up top in the same tray. Unlike their dual battery system, this one just acts like the normal ESS system but with matching batteries, which may last longer being both of the same size.

Either one can be upgraded to their full dual-battery system later if you have the need. The full system has their intelligent charging system intended for use with overlanding-style applications.

Love ESS but hate the battery location? 2 new options from Genesis Offroad!

My take:

Both versions make it a little harder to get to the fuse box, but that's a small price to pay compared to the hour or more it took to replace the ESS battery through the fender liner in the cold and wet the night before the deep freeze arrived. Now having two fresh new batteries, I'd start with the relocation system to get my money out of those batteries before maybe upgrading later. If you have older batteries it almost makes sense to do the relocation or replacement system now at your leisure before they go bad at some inconvenient time.

Also, some have mentioned that it isn't easy to source group 25 batteries. You almost have to have them on hand before needing them, or swap out early as a preventative measure. Otherwise you may end up having to use whatever you can find locally in an emergency.

Finally, I currently use the ESS system as an early warning of battery failure. I usually forget to turn the system off, so at some point it shuts down the engine at a traffic light. If that happens then I know the batteries are still pretty good, and I turn the ESS off and continue down the road, keeping the system off so the truck can recharge to full if possible. I might turn the ESS back on if stopped for a freight train, but otherwise I want the engine to continue charging.

If days pass where it never shuts off when I thought it might, then maybe it's time to upgrade the batteries.

I plan on keeping my system stock except for a taser to turn off the ESS. I'll upgrade to Odyssey batteries.

This is a really great solution! Especially for those wanting to retain a stock setup and still have a Genesis style control system for aux batteries. Man great work at developing new things.

Why are group 25 batteries so expensive? Also not very easy to find.

I just ordered their stock battery relocation tray. Although it relocates the Aux battery up top above the fuse box, that part just bolts on. Being I am deleting the Aux battery, this kit will alow me to use the stock battery size instead of duel group 25 batteries. So really the only thing I get out if it is a cleaner, not as bulky battery box - that is good enough for me!!!

Dayusmc , if you are deleting the ess battery, why bother with their tray system , why not eliminate the ESS system and battery then swap out the stock battery for a larger 94R battery which fits in the standard tray by removing the spacer at front of tray, it is just taking a screw out. I did it on my wife’s JL when battery went ,even cut the insulation cover to put on larger battery….Jack

PS: I do like Genesis, and it is a great idea if you want to keep ESS, and am installing their dual battery system to help with my fridge, but getting rid of ESS.

My Mojave came with the 94R battery from the factory. I like the cleaner look of the Genesis battery tray over the stock one, that is why I am changing it. It looks like it will also give me more access around it to clean the engine compartment over the stock one.

Dayusmc, just did a Genesis dual battery in my Mojave today, deleted Aux battery, all the wiring including the negative from main battery, jumper on N1 to N3, turned out real nice, just have to remount my Warn winch control box now! When you loosen the four screws inside fuse box, make sure they are all the way loose, they hold the plugs tight to fuse box…..Jack

That looks so clean. Should come factory.

I will be doing mine soon, once my cables come in....

Iagreee putting the aux. battery, under the fuse box is nuts, it takes awhile to get it out, there is enough room that factory could have fit it in next to main battery somehow.....Jack

@Jaxmax
What year is your Mojave?

 

[Jaxmax]

My Mojave is a 2021, I did unwrap the cable from battery to Aux battery, so there is only two wires there now....Jack

I know there was a change in the wiring harness some time in 2021. Did your remove your PCR also?
