Jeep JL & Gladiator Gen 3 Dual Battery Kit Installation Guide 

We could look into that!

Any updates on the above question by Bizz Fo?

@@GenesisOffroad Absolutely great idea ...many ppl dont feel comftrable / warranty wise changing the system up the relocation kit would be a great sale \-/

Ok

I would definitely buy stock relocating aux battery

Thank you very much!

Awesome, thank you!

Thank you!!

How’s it working? Did it cause any problems with the JT’s computer?

@@onebridge7231 no issues since installing. Has been great!

​@@off-roadskys4250 does the green light around the switch stay on?? I installed mine yesterday and it hasn't shut off

@@onebridge7231 no problems at all.

Yep, you can thank the EPA and their retarded policies that are not even constitutional! They are just a thug three letter agency, that is making laws, with no accountability & reports to no one. YJ's and TJ's are awesome. Easy to work on.

I’m about to buy a gladiator but keeping the TJ for sure. I wish they’d make new cars with old tech

You’re going to love switching to the JL eventually. It is 100 times better in every way!

Thank you for the feedback! You are correct about the dipstick, it is easy to bend it towards the engine slightly. Sorry we forgot to mention that in this video. It was included in our original video before the Gen 3 kit was released. And you are correct that the top plate is grounded, since the tray is bolted to the body, and the lid is bolted to the tray, it does conduct to the body ground, but then again, so is the fender, and hood, and engine, etc.

The diesel Gladiator kit is available now! www.genesisoffroad.com/gen3-diesel-jt-dual-battery-kit

@@GenesisOffroad any for Wranglers? Or is that later this year.

The diesel Gladiator kit just launched! www.genesisoffroad.com/gen3-diesel-jt-dual-battery-kit The diesel/392 Wrangler kit is now available too! www.genesisoffroad.com/gen3-diesel-jl-dual-battery-kit

Have you solved you problem? I had the same issue so I just deleted my Aux battery from for 2018 JL.

Yes. Our DIY kit comes with just the battery tray and a bare lid, with no wires or electronics - www.genesisoffroad.com/jl-diy-dual-battery-kit

If you installed our kit into your JK, then you could definitely install the JL version, it is actually an easier install than the JK kit.

Nice! We keep kits in stock all the time for super fast shipping!

Diesel JT kits should be shipping by 3rd or 4th week of October. Diesel / 392 Wrangler kits should be available in November.

Yes, this video will walk you through how to do it step by step.

Yes the entire stock plastic battery tray gets removed including the area that held the small aux battery. You can see that around the 13:08 mark. We do ship to Canada. Our website will show you some shipping rate options before you checkout. Please be aware that our website is not able to calculate any additional import duties or fees that the Customs office may add when it crosses the border. There were no changes to the battery compartment area for the 2024 models, so yours should look just like this video. We have lots of customers that run our dual battery kit even without hardly any aftermarket accessories. You'll still benefit from getting rid of the small aux battery, and be able to jump start yourself if your cranking battery gets too low to start the engine. Then later if you do add some accessories, those things will be able to run from the second battery and will not drain your cranking battery. We carry Odyssey and Full Throttle batteries. Both are excellent high quality batteries, you can't go wrong with either one. The Full Throttle one does have a little bit more capacity than the Odyssey though. Hope this helps! -Shane

You can email us your zip code and we'll respond with the nearest installer. The short answer to the warranty question is no. For more details, please watch this video clip - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tRe2Mjps0sg.html

The problem is that your factory positive and negative post clamps do not have any slack on them at all, so they will not reach over to the other side of the battery if you have the posts reversed. We have had some customers who added a one foot long battery cable onto the stock post clamps to extend them over to the other side. It will work, but it will look really messy, and you'll have to be very careful that your factory clamps do not touch the wrong posts on the batteries - your factory positive would end up being right next to the negative post on your battery. This is why we specify Group 25 batteries are required. All the wires will fall perfectly into the right place. Also, the top plastic cover is not intended to be removed because there are no end-user serviceable parts under there. Changing any of the wires under the cover will void your warranty.

Yes we have lots of customers running the switch pros box with our kit. The owner of Switch Pros also uses our kit.

Glad you got it figured out! Feel free to give us a call if you need any more help! 901-214-5337

@@iliketocamp1342 yes it does

@@henrybucki7813 Thank you,I was worried I screwed up the easiest mod ever. 😅

@@iliketocamp1342 every time ive looked under hood while it was in the basement where the lights are dimmer than outside i see the light on the switch lite up

@@henrybucki7813 Did you have any issues with yours being against the dip stick? Thanks for all your help

yes

Yes you can connect the trickle charger to the bus bars and it will charge both batteries. I'm assuming your tow controller has a low voltage cutoff feature. That's fine, just connect it to our bus bars. Our system will protect the cranking battery from being drained down by anything that is connected to the bus bars.

This is what I like to know as well

Yes

No, our dual battery system will not make any noise like that. It will make a very noticeable click sounds when it connects or disconnects the batteries, but that's all.

???

This should work with the ESS system. I asked them the same question a while back and they confirmed it.

No. For right hand drive JLs, we'd recommend our new kit that puts the second battery and the electronics under the back seat - www.genesisoffroad.com/gen3-diesel-jl-dual-battery-kit

Yes, and we can certainly understand the concern. The cost of every single component has gone WAY up over the past couple years, along with everything else everywhere. The price is where it must be for us to operate a business. We have kits in stock for quick shipping when you're ready!

2 grand ????????????

You'd need to relocate it somewhere else.

Our kit links the batteries in parallel, which keeps it a 12v system. There are aftermarket devices that can convert 12v to 24v. You can connect that to our bus bars so that your 24v accessories would not drain down your cranking battery.

Here's the diesel/392 kit for the Wrangler - www.genesisoffroad.com/gen3-diesel-jl-dual-battery-kit

We have seen pictures of that snorkel installed with our kit on the Jeep Gladiator's Only facebook group. However, we have also heard from some customers that they couldn't get it installed. I think it can be done, but will probably need some modifications.

The brand doesn't matter, it just has to be a Group 25 size to fit into our tray and also so that the factory wires line up properly with the posts. For more details, watch this video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JopB0I1CRzY.html

When we come up with new features for the G Screen that are solely software based, then we do those upgrades for free. If the new features requires a change to the hardware, such as when we added the port for plugging in the optional air pressure sensor cable, then there will be a small fee for swapping out the hardware, but we try to keep that as minimal as possible.

Wow!! I wouldn’t buy it just for the fact that it’s $100 shipping!

All the components in our kit are rated for under hood temperatures, up to 105c, or 221F.

The positive wire from the small battery will be connected to the positive of the cranking battery. The negative wire from the small battery is not reused.

@@GenesisOffroad aren’t you basically doing an AUX battery delete by not utilizing the AUX negative cable? Please explain if this new set up makes the Accessory battery the new AUX battery or if the AUX battery is now 100% eliminated. Thanks

@@omarvilla7476 Allow me to clarify. When we say we are eliminating the aux battery, what we mean is we are not reusing the small factory battery under the fuse box. We are adding a second full sized battery which will be the new aux battery in our configuration. The one closest to the fuse box is the cranking battery, and the one towards the front of the vehicle is the new aux battery. The factory negative cable originally went from the small battery up to the big battery's negative post. Our kit comes with a new heavy duty cable that links the 2 negative posts together, so therefore the original cable is no longer needed. You can see more details on that in the video at the 22:12 mark. I hope this helps!

We don't have a dual battery tray for under the hood of the right hand drive JL, but you can use our new kit that puts the second battery and the electronics under the back seat. You can see that kit here - www.genesisoffroad.com/gen3-diesel-jl-dual-battery-kit

Yes, you can upgrade your existing kit to the new Gen 3 Power Hub. Here's a brief video about that - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rG_FAdel8sI.html and you can order the power hub upgrade here - www.genesisoffroad.com/25-power-hub

Yes, the kit and the install process is the same for the e-torque models.

The short answer is no. For more information about that, please watch this clip from our 'Top 9 Questions' video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tRe2Mjps0sg.html

Sí, este sistema elimina la pequeña batería auxiliar y la reemplaza con una segunda batería de tamaño completo.

Based on the brief info here, it sounds like your cranking battery may be low. Do you have the G Screen to check its voltage? If not, a handheld voltmeter would help verify. If it is indeed low, just put it on a battery charger overnight (one that can put out at least 20 amps) and then check it again. Our engine on sensor cable will prevent the smart isolator from separating the batteries while you are driving. If that cable were not working properly, then you may see the accessory battery going low. The cranking battery gets power from the alternator all the time. Hope this helps. If you need to talk through it more, please give us a call. 901-214-5337

@@GenesisOffroad what would be considered low?

@@advapp AGM batteries are fully charged at 12.83v. If it is down below about 11.8 or 11.9, then the engine probably won't start. If it's not starting the engine, you'd definitely want to charge it. Then for general maintenance, if you see it below about 12.3 or so, it would probably be beneficial to throw a charger on it overnight to top it off. That will help extend the lifespan of your battery.

@@GenesisOffroad why wouldn't my alternator charge it That's my question? Cuz it's brand new and I look inside my gauges on my JL and it shows 14 to 14.5 volts charging?

@@GenesisOffroad and I know it's not your system I'm just trying to get to the bottom of it because it's hard to Google this you know cuz most people don't have dual batteries.... When I go to test it if I just turn the switch to off which would disconnect the batteries would that be a good way to test it or should I just remove the terminals all together off the crank off the accessory battery?

That is not necessary.

@@GenesisOffroad but can it be? Even if not necessary?

@@jojobernard625 Sure. It would just create a loop, that's all. Certainly won't hurt anything though.

No, the Wrangler 392 kit is different. We expect to launch the 392 kit very soon. Check this page for availability details - www.genesisoffroad.com/gen3-diesel-jl-dual-battery-kit

Our system eliminates the small aux battery and gives you a second full size battery.

We recommend using the Tazer from Z Automotive for disabling the stop/start system - www.zautomotive.com/product/z_tzr_jlm/#camera-kit

when the green light is on it simply means the batteries are connected together. They will remain connected until they drop below approx 12.7v. Then the light turns off to indicate the batteries are isolated. For more details check it this video which talks in depth about the green light as well as the G Screen. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4TO7FXf_GLs.html

@@GenesisOffroad I was just worried, thanks

Yes! You can see that kit at the link below. We also have a detailed installation video for it on our youtube channel. www.genesisoffroad.com/gen3-diesel-jt-dual-battery-kit

We haven't had an opportunity to check that yet, but I'd say it probably will work. The Gen 3 version is very nearly the same physical footprint as our earlier model, so it should work. When we get confirmation of that, we will add that info to the 'Fitment' tab on the website here - www.genesisoffroad.com/gen3-jl-dual-battery-kit#tab-7

Ill let you know soon mine is supposed to be delivered tomorrow ......

@@mrr.6313 Thanks! :)

@@GenesisOffroad sooo I finally got it installed today......I have a 2020 jlur.....with the amfib snorkel .......it fits but by less than the skin on your teeth.....the aux battery positive post sticks right up in front of there the snorkel meets the air box ..but because of the rubber connections at this point the rubber flexes over the post and the clamps sit on either side of the post .....the bus bar lid has to be slightly modified to close properly ...just notched the corner out and it worked ....the snorkel sits ever so slightly higher and you have to push the hood closed gently as it hits the insulation for the hood ....those are the major points ....but yes t will work if you work it in .....

Yes. This video has more info about solar panels - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tRe2Mjps0sg.html&feature=shared

After looking at their pictures on this page - store.switchpros.com/jeep-jl-jt-mounting-kit-19-23/ it looks like their bracket hangs down into the space that is consumed by the batteries in our kit. I'd recommend talking to them about alternate mounting options. Perhaps it could be mounted on the firewall over the fuse box.

@@GenesisOffroad ok thanks I’ll check into it

It has to be a Group 25 size to fit into our tray. For more details on why, watch this - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JopB0I1CRzY.html

@@GenesisOffroad thanks. Just placed an order for Gen 3

@@kazochrymowicz3076 awesome, thank you!

Lithium batteries have several benefits, but also several drawbacks. They do not like high temperatures, and they cannot be charged at below freezing temperatures. They also don't like high amp draws, such as when using a winch. For those reasons, we feel AGM is still the best choice especially for our kits that put 2 batteries under the hood.

The engine compartment is way to hot for lithium batteries. Even more important is that if your "2" batteries are heavily discharged, the current acceptance rate of the lithium batteries will overheat your alternator and destroy it. Several videos on You Tube about this. A Jeep Wrangler is not an acceptable use for lithium batteries even if you add a DC-DC charge controller.@@GenesisOffroad

@@ronrosenberg4058 good points.

Excellent question! The reason we made it an optional add on rather than including it in every kit is because most other vehicles do not need it. We have only had a handful of customers with the JL/JT report the issue with the alternator turning down its output low enough to cause the isolator to separate the batteries while driving. Therefore we didn’t want every customer to have to pay for the sensor cable, in an effort to keep the price as low as we could.

We do not do any labor for customers, however, your local 4x4 shop will typically bill you for 2 hours of labor to install this dual battery kit on a stock vehicle.

Yes

You can use the cig lighter / 12v power outlet circuit.

Because not every vehicle needs it.

Yes

We have kits specifically for the diesel Wranger and another one for the diesel Gladiator. Check our channel to see overview videos and detailed installation videos for both.

That's awesome! Your kit was designed to be super heavy duty, and outlast your vehicle! But if you do decide one day that you'd like to have the features of the Gen 3 system, it's an easy upgrade. Check here for more info! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rG_FAdel8sI.html

Yeah just installed mine two weeks ago. Asked them the same question got a thumbs up 👍🏻 no response. After spending $1400.00 kind of makes you feel ripped off.

@@photoapeal Why? The Gen 2 kits are still available, and they are still as high quality today as they were 2 weeks ago. As far as timing with the new kit, it's one of those things like buying a new cell phone and then the next day a new model comes out. Just how it is sometimes, but doesn't mean the original phone is obsolete or anything.

@@GenesisOffroad You feel like you just purchased the lesser model since improvements or fixes came out within a few days of your purchase and you got the older version which doesn't have those. You feel ripped off since if you had known you wouldn't have purchased the older version which is inferior to the new version as stated in your video. It was $1400 bucks in my case since I purchased the batteries with it.

@@photoapeal I hear ya. But we certainly don't want you to feel bad about your purchase. We have had several customers order the Gen 2 kit instead of the Gen 3 kit already. Partially because the Gen 2 kit is less expensive, but also partially because they had been researching our system for quite a while and decided to go for it and knew the Gen 2 would work great for their purpose.

We have plenty of kits and batteries in stock when you’re ready!

The batteries are $329 each. So you think we should include two of them with the kit for $699? Which basically means the cost of the kit itself goes from $699 to $40? I don't think that's gonna work. As for the sensor cable, not every vehicle needs it, and we did not build the cost of the cable into the price of the kit. But maybe we should just charge everyone $714 for the kit, whether they need the cable or not? YIKES.

@@GenesisOffroad no I don’t think batteries should be included. But for what IS included. I think there’s wiggle room to include the $4-7 COST Sensor. It’s a very nice kit. And I don’t think your profit margin will suffer with the sensor.

That’s ok! You could have your local shop that you trust do the install for you. They will only bill 2 hours of labor for installation.

I just installed my Gen 3 version today. It took me about 2.5 hours to do and that included getting my winch cables re-routed and hooked up. Doing it yourself is rewarding!

What leads are you referring to? Send us a picture to info@genesisoffroad.com and maybe we can help.

@@GenesisOffroad I can send one tomorrow. I cut both rings and then was able to stretch them over the middle post. Then I was able to attach the aux positive to the post on the left. It’s all back together now. I will test tomorrow. I added my six switches after I bought the gladiator. The positive leads (2) attach to the post on the left. Makes it just hair to thick to attach the aux cable (I did flip it per instructional video). It’s all good now I think. Thank you for replying. It glooms like a great product so far.

The diesel Gladiator kit launched on November 1. The diesel/392 Wrangler kit is now in stock and will be available to purchase on our website as soon as we get pictures and videos.

I'm sorry I'm not familiar with that kit. I just looked it up on their website and the only pictures I saw under the hood had the device mounted by the brake booster. Was yours a custom installation?
