Protect your cranking battery from getting drained by your accessories.
The OMEGA system is a plug-and-play aux battery system for the Ineos Grenadier. It is completely pre-wired and designed to fit under the back seat, with a Redarc Alpha 25A DC-DC charger, 50A Anderson plug for solar panel input, bus bars for connecting your electrical accessories, and an adjustable battery bracket for your choice of various sizes of lead acid, AGM, or lithium batteries.
Aux battery sold separately. See FAQs below for more battery fitment details.
Important Fitment Notes:
For Grenadier owners with the factory JBL Nano speaker, we have an optional Relocation Bracket with wire harness extension to easily mount it under the front passenger's seat. See options below.
This kit is compatible with Grenadiers with OR without the extra switches in the overhead panel (the High Load Auxiliary Switch Panel & Electrical Preparation package) which has an extra fuse box under the back seat.
This kit is designed for Grenadiers that DO NOT have the factory second battery option (this option was discontinued for the 2025 year model). To use our kit instead of the factory second battery option, the factory electrical components under the back seat would need to be removed first. We will offer documentation on that process in the future.
Some base model Grenadiers that do not have the factory speaker may not have the factory brackets under the back seat which are used to secure the new battery in place. We are currently working on sourcing those factory brackets. More details coming soon.
OUR GOAL IS SIMPLE:
POWER YOUR ACCESSORIES WITHOUT DRAINING YOUR CRANKING BATTERY

The Redarc Alpha and charger has an integrated MPPT solar charger controller built in. No additional charge controller device is required. The Omega lid includes a 50 amp Anderson plug for connecting directly to your solar panels. If your brand of solar panels come with a different connector such as MC4 connectors, you will need an adapter to plug them into the Anderson plug.
To use a traditional battery charger while the engine is off, you can connect it directly to the positive and negative posts of the battery that you wish to charge. The Omega system does NOT link the batteries together, so that means each battery will need to be charged independently.
Please keep in mind that your factory fuse box gets its power directly from your cranking battery all the time. The Omega system does not link the batteries together in parallel, but with the Alpha charger, you can use its 'Start Recovery Mode' feature which will charge up your cranking battery by powering the Alpha charger from the accessory battery for 15 minutes to help get the cranking battery recharged enough to start the engine.
Most factory battery post clamps are made of light duty stamped sheetmetal, and stretch or wear out over time. First, make sure the post clamp is fully seated all the way to the bottom of the battery post. Try loosing up the post clamp nut so it is very loose, then use a large socket and gently tap the clamp down onto the post. Now tighten the clamp nut and see if it is secure. You can also try using a battery post shim, available from your local auto parts store, to fill the gap between the clamp and the post, allowing the clamp to tighten down more securely.
The sPOD unit should be connected directly to the bus bars. This way, anything that you are controlling through the sPOD will get power from the aux battery, and will not drain down your cranking battery. Any other aftermarket electrical accessory wires should also be connected directly to the auxiliary bus bars to avoid accidentally draining down your cranking battery.

RELOCATE THE FACTORY JBL NANO SUBWOOFER WITH THIS KIT
This kit will relocate the Grenadier's factory JBL Nano subwoofer from under the back seat to under the front seat. You can select from the options below for mounting it under the front left or front right seat.
If you are installing our dual battery system in your Grenadier, or any other accessory that needs to mount under the back seat, this is the easiest way to relocate the factory speaker.
Included is the bracket to mount the speaker and a 42" wiring extension harness. Installs with factory bolts under the seat, and reuses the factory screws to attach the speaker to the bracket.
The speaker is mounted high enough off the floor to fit the factory tool kit bag and an umbrella under it.
Also fits Right Hand Drive vehicles.
Available for mounting the speaker under either side. Choose left side (the driver's side in USA, passenger's side for RHD vehicles) or right side (the passenger's side in USA, driver's side for RHD vehicles) from the option below.
Overall rating: 4.8 / 5 from 6 reviews.
This thing is great! The install was relatively straight forward, just needed to go out and get a T50 bit. My vehicle is a 2026 Trialmaster with the high load aux system. Also has the JBL subwoofer under the rear seats. The install video does not have the high power load aux system, so there were some differences in my install such as not being able to access one screw, which is fine with me. Not sure why they did not include the BCDC 50A over the 25A, like some of the other competitors.
Great pre built kit which was super easy to install with the help of the install video. Delivery was super quick to Australia and the team were fantastic answering all my questions before purchase. Would 100% recommend.
Fitted it to a two seater Grenadier which i'm guessing you don't have your side of the Pond. I had to modify the mounting chasis to avoid a hinge mounting for the one piece cover that hides the batteries/electrics. If you guys get the two seater, it would not be a major change to do a "one fits all" set up. Cheers 4 now. BM.
Ineos Grenadier OMEGA Dual Battery System
Store owner replied: Thanks Brendan, I'm glad you're happy with the Omega system! I think you're referring to the Utility Wagon version - we are already working on adapting our Omega system to fit that one, it should be ready sometime soon. Please let us know if you have any questions or need anything, we're here to help! -Shane
Kit seems to work great. I erroneously ordered the kit not realizing until after my Quartermaster showed up that it had the factory dual battery set up installed. SO....I had a much more involved install to remove the factory system to install this system. Once the factory system was removed the install was remarkably simple, although the bolts holding down the redarc were a little too short in a quartermaster install as it seems like the quartermaster seat base mounts just a little differently than a station wagon so the bolts supplied needed roughly 1/8" longer to reach the studs, absolutely would NOT thread with supplied bolts. Fantastic system.
I ordered the auxiliary bracket but this was not included in the shipment. The other parts work really well and the install video was most helpful. The packaging was amazing and the best I have seen to date. Great product and service to match.
Amazing product!! As all the genesis products .. this is the second battery system that I got from them and everything is perfect… installation is a breeze and it looks like it comes from factory with it!! 💪🏻💪🏻💪🏻
