Dual Battery Question

[enjoitheride]

Hello, everyone. Since the 2025’s are absent of the dual battery, I have a question:

Is the truck still setup for a dual battery? I know Genesis is coming out with a Redarc unit, but I can tell if that’s just to power/charge starter battery with solar and alternator.

Am I missing out on not having the factory dual battery system? There was some confusion from the dealer in explaining the current setup and I thought it was all there, but I had to pick my own battery of choice. They made it sound like people weren’t happy with the factory secondary battery, and that customers wanted to choose what went in there.

Thanks in advance.

Dual battery is no longer an option from INEOS. Lynn Calder interview tells you why.

There are only third party options now. You are not missing out if you choose a good third party supplier, suited to your needs.

Thank you for the reply. I will have to look around and see who’s going to make the best dual battery option. I like really high quality.

Sorry, I must have misread your post. I thought you were asking about the roof shelf.

For a dual battery, you'll need a specific kit. The main challenge is finding space under the hood. Check what aftermarket suppliers like Red Winch or Bison Gear offer for the Grenadier, as it's likely the same for the Quartermaster. A professional installation is a good idea to keep the warranty intact.

It isn’t a proper “house” battery set up like nearly all of us have had in the past. As such, if I had my time again I would have not got it (although it was standard with the trialmaster) and spent my money more wisely.
That said, I’ve had a few instances where dormant draw has meant I’ve been down to 50% battery after a couple of weeks of no use which might have meant a single battery would have been flat.

These days, I reckon a dedicated car charger serving something like a Bluetti power station is a much more versatile set up than a traditional dual battery set up. I’m seriously looking at using that to power my fridge and other bits and pieces on long trips going forward.

Are you suggesting a dual battery system is fitted under the hood . That sounds like an AI answer

The Ineos Dual system is a redundant system not house battery. for reliability in the field, i kinda like that. I've done it both ways, and I've found complaints to be much ado about nothing. Even tho power stations suck up valuable space, if you have the dual battery, and you run one of the smaller power stations off of the primary, you've got yourself a rather resilient but simple system that's less likely to leave you hanging in the empty quarter than a complicated but poorly designed or monitored dual house battery. I guess it all depends on how "techie" and needy you are. I carry a cot and a tarp for reference.

I wanted it just for that; redundancy. I have an AEV GMC 2500 for my travel/ camp rig.

There are clearly some guys here that love automotive wiring, and I’m not one of them. I’ve used this on more than one rig. What I like about it, is I put a momentary contact toggle on the dash and I can combine the batteries for jump start or to mitigate voltage drop during winching. If you put a second battery in the open battery slot of a ‘25, I don’t know why it wouldn’t work… other than… if this would cause issues with a smart alternator. I don’t know why it would, but I must be dumber than a smart alternator as I prefer a gm one wire for a remote travel truck

No, it is not an ai answer. the Grenadier, check if your specific model has a second battery under the hood. It was an option, not standard on all vehicles.

Really that's the first I've heard of this. Every Grenadier I've looked at has had the optional Auxiliary battery under the rear passenger seat and the online workshop manual only shows the battery there, no where else. I also struggle to see how INEOS could fit a battery under the hood without major component repositioning.

If you could provide any supporting evidence it would be appreciated

Alright, I'm intrigued. Please tell me more about this second battery under the hood option. And to be clear, you're talking about up front in the engine compartment? (hood = bonnet in other parts of the world)

I'm very confident that all Grenadier and QM to date have the starter/main battery fitted under the rear seat. If the auxiliary battery option is installed then it goes under the rear seat on the opposite side. That's the factory configuration. Aftermarket might do something else.

Its clearly someone confused. there is no second battery under the hood. there isn't even a first battery under the hood.
The first batter and (if so equipped) the second battery sits under the rear passenger seats. This guy must be thinking of another manufacturer.

to the OP. I personally didn't get a factory dual battery option. I added the RedArc DC-DC alpha50 to my car and attached a battery in the same space as where the factory placed the second battery under the passenger seat. I added a lithium battery since that aligned better with what i wanted.

to mount this i got brackets for both the redarc and the battery from more4x4 in australia (i picked it up on a business trip). There are others who make similar brackets, GP Factor in the US makes a highly regarded bracket.

I considered a battery in a box in my trunk - a bluetti and others. But in the end i chose to prioritize having trunk space. The space for the battery under the seat was free so that is what i used. i don't think you can go wrong by picking either one approach.
