Dual Battery Setups! Let's see them! Multiple Batteries Thread!

Im going to do something like that. Already have the 2nd battery in that location, and my solar charger (which I want to switch out to a CTEK or Redarc)(And I hope its waterproof because its been outside for over a year ). I just need to get some wires and loom and work on making my stuff clean like that. I wont be putting my air compressor there.

 

How is it running an agm and a lithium at the same time?

 

On that picture? Id think that one is the starting battery, relocated to the bed. And maybe the Redarc is inbetween?

 

Ahhhhh.....makes sense now. A relocation is a tricky thing.

 

Looks like the odyssey is the starting battery relocated to the bed with the Lithium as the house battery. Controlled by a REDARC BCSD1250 in the top right corner controlling them.

 

I have a gel and a agm. But they are not linked.

 

Maybe there are three batteries? OH HOLY BATTERY MYSTERY....LOL
My truck has a starting battery, (wet) because that's what it's supposed to do, and I have a AGM in the bed, for lights, refer, radios and when it's time, I may add a 3rd for the winch, air compressor, and welder.
Let the MIND PHUCK BEGIN...lmao

its @adventure.discovery on instagram. Dont know if he is on here. Maybe @LTDSC knows what his username is on TW

 

I'm sure I should read more before I ask, but is that your truck?


EDIT: Shit shoulda just read more ^

 

So for those 2nd gen guys with the in-cab ML-ACR switch.. where did you mount the rocker switch?

I know Ive seen pictures of it mounted to the left of the A-TRAC but I cant for the life of me find any pics of it. It looks like there would be a pretty significant amount of trimming required to get it to fit there. All the spots to the left of the steering wheel are full in my truck, so thats a no-go.

Any other good spots people have used or seen?

 

Just to your point about trimming, the ACR remote switch is a Carling size switch. The ACR remote switch can’t really be trimmed- it’s one sealed unit. Hope thats useful or at least confirms what you already were thinking.

 

Yup, guess I meant trimming the plastic dash piece where those two blank switch pockets are. They are definitely not big enough for a Carling style switch.

 

Def not. An adaptor plate has to exist someplace so you don’t have to chop things up!

 

Honestly I have no idea why someone would relocate the truck battery to the rear of the truck except for weight distribution and safety as in drag racing. The old school theory of having some extra weight on the right rear is sort of a myth but if anything, I'd want that weight up on the left front...lol. Just sayin.

Edit; for the record, this guy is having a lot of fun @adventure_discovery insta. lol

 

You want as much weight over the rear axle as possible for go fast performance - look at spare tire and fuel cell location in trophy trucks and prerunners. Our trucks core support can’t handle weight of one battery doing serious off-roading as well. Look at this:

If you’re just putzing down fire roads then yeah, doesn’t matter where batteries go.

 

Do you have to have there switch?
Aka do you have to have in cab disconnect and/or connect?
You can use a ch4x4 or mictuning factory style switch, you just loose one of the functions.

for me I chose to keep the force connect, so I’ve got a push button under the hvac controls in a stock blank. Force disconnect can be don’t at the ml-acr

 

That is a possibility. I really like the status feedback given by the Bluesea LEDs though. Plus I do actually use it quite a bit in the cab

 

Depending on where you mount the acr you can hear it connect and disconnect.
I’ve used the force connect to make sure it’s connected at time since running solar but over all there lights seam rudemetric
