Aux battery system

ninster · Sep 15, 2024

Hi all , hope you are having fun with your INEOS . I purchase mine with the aux system, when I received it the sales rep said that I didn’t have the aux battery due that I purchased the upgraded entertainment system and the battery could not fit . I am supposed to have all the wiring in place . How can I do a work around to get the power I need ? Can’t see the truck battery to support a campsite .
Thanks

In the back under the rear seat I have a JBL woofer , I don’t have a thing else in that side . Sale rep stated the power system will work from the main battery . I do not see how . Now wondering what I paid for

So you paid for all the wiring and switches on the roof. You have all the fuses and what your missing is the aux battery and the Smart pass 120. Even on the grenadiers with dual batteries, all the switches and everything run off the main battery. The Smart pass 120 then trickle charges the main battery from the aux battery. To replicate, you need to buy a battery, Smart pass 120, battery holder, busbars and cables to wire everything up.

Instead of replicating the factory aux battery setup, I would add a lithium auxiliary battery and join that to the vehicle's electrical system via a DC-DC charger such as a Renogy DCDC-MPPT. This would charge your aux battery when the vehicle is running. Wire all your camp loads like lights, fridge etc to the aux battery only. This way your camp loads will never drain the starter.

The battery will fit under the rear passenger seat, but you may need to buy or make battery holder. You may not be able to fit a large 100Ah battery with the factory subwoofer there, but you should be able to fit at least a 50Ah. There is also space under the rear passenger seat for your DCDC charger and other related wiring.

Sorry to bump this thread back up

I am in the exact same situation. Is there a way to move the JBL subwoofer elsewhere while will installing a 100ah battery?

I bought the battery and I want any kind of advice that I can get.

I haven't seen the factory sub and don't know it's sizing, but these guys make a complete system, including a custom sub that fits perfectly under the front seat. THey would probably sell it separately instead of only as part of a system. https://shop.car-u-audio.de/fahrzeugspezifisch/ineos.html There's a youtube video somewhere that shows how they built the enclosure for the sub. Maybe you could do something similar with the factory sub.

I installed a sub, not JBL, above the handbrake mechanism on a home made bracket.

I don't know the size of the JBL as to whether it will fit there.
