2018+ Jeep JL / JT Stock Battery Relocation Kit

Easier Access to the Small ESS Battery

We may never understand why Jeep decided to put the ESS battery in an inaccessible location under the fuse box, but we have a fix for that. This kit will relocate the stock ESS battery on top of the fuse box for easier access for servicing it in the future. 

This kit is perfect for Jeep owners who like the ESS system and do NOT want to disable it, but want an easier way to maintain or replace the small stock battery in the future. No more removing the factory fuse box or pulling out the inner fender liner to access your small battery!

This kit can be easily upgraded to our full dual battery system by replacing the top bracket with the Gen 3 Power Hub

Battery Requirements

Requires the stock Aux 14 size ESS battery and the stock Group 94R Crank battery.

* NOTE Jeep used 2 different sizes for the large battery. Depending on your vehicle's options, your stock battery may be a Group 48 or a Group 94R. This kit is designed to hold the Group 94R size only. If you are replacing your original stock Group 48 battery, you'll need to get the 94R. They are normally the same price but the 94R has more capacity and more cold cranking amps so there is no benefit of using the smaller Group 48 size.

You can use any battery brand. We offer the Aux 14 size from Odyssey, and the Group 94R from both Odyssey and Full Throttle. These are the highest quality AGM batteries on the market. Add one or both of these from the options above.

Batteries ordered from us will ship separately from a warehouse located in Southern California.

ESS Functionality

All wiring remains 100% stock, with no changes to the ESS (Engine Stop Start) system at all.

Install Time

Approximately 2 hours on a stock vehicle. Add time as appropriate if you need to move some aftermarket devices or reroute accessory wires.
