Post Your Auxiliary Battery/Fuse Box/Power Setup (1 Viewer)

[GOTLOCKED96]

I know over the last couple of years options have expanded for adding dual batteries, auxiliary fuse boxes, and running auxiliary power to the rear.

It would be extremely helpful for newer members like myself to see pictures and specs for some of these set ups.

Thanks Fellas.

All my aux power is tapped from the main battery and run to my home grown rear passenger quarter panel. Here's the most recent pic of the QP area.

The front battery is an X2 crank/deep cycle model. I may add a 2nd but I've not needed it in 7x years. If I do, it would be wired in parallel with this one to avoid any rewiring and give me around 180 hours of reserve time. I have solar on top that keeps everything happy including the ARB 50 fridge that runs 24/7.

Very impressive. Clean work my man. What are the skate board wheels for?

Maybe something to hold an air hose?

Yeah the first reply kind of crushed it..

Not very exciting but proven rock solid and seamless operation. Powers fridge, several outlets, large compressor, inverter, heated poptop along with several accessories. I subscribe to the set it up and forget it system.

Dual batteries that DONT ever separate
2nd battery in the rear corner
100watt of solar
No additional fuse panel just breakers under the center console
Large breakers for batteries
Shore power
Small plug in inverter

The set up sees over 100 nights of use per year and has for several years without ever a glitch.

This is in my future! Subscribed.

My setup is (almost) as simple as it gets. Switch allows for none, battery A, battery B, or both. Battery B has ANL fuse near battery and then 4 gauge wires to the rear. This then runs an inverter and a couple of power ports. I plug my fridge into one and the other gets used for things like USB power, etc.

When camped, I put switch to A only so that battery B is disconnected from everything and runs the fridge and inverter. This way they cannot drain the other battery. Normal driving has it in dual mode and when parked for any length of time (yes, it sits for weeks unused), I put it to none. Just yesterday, I went to start it. I had left it on A and apparently a parasitic draw was enough to make it barely crank after a month. Just switched it to B to start it and then to both to charge both back up.

Thank you. Those are to fit a Water Brick over to hold it in place on the shelf. The wheels fit perfectly in the 2x holes in the brick and keep it from moving horizontally. I can stack 2x bricks (7gal total) and have a long eye bolt that secures them so they can't move vertically (screws into the long nut above the wheel).

How do you wire your switches with the bluesea block? I sure wish Bluesea made a relay box.

My block will just run radio, led lights, some aux 12V ports. I don’t think a relay is necessary and my OTTRAM switches handle up to 20Amps. I don’t see myself running anything over 20A in automotive application tbh. So I have have it go directly to the switch.

Makes sense. I love repurposing things. That’s why I don’t throw sh1t away!

I added a second battery for house/aux loads. 92AH Deka AGM deep cycle 27M.

Blue Sea ML-ACR with cab switch for combining and separating start and house batteries.

Redarc BCDC 1225d to charge aux battery thru alternator and/or solar.

Blue Sea 6 circuit fuseblock behind start battery wired to start battery mainly for lighting needs.

Blue Sea 12 circuit fuseblock under drivers seat wired to aux battery for all interior power needs.
Multiple Blue Sea AMG and ANL blocks for compressor load and other high amp loads.
In cab Ammeter and dual voltmeter for monitoring.
Winch to start battery with 500A switch on positive.

This setup allows me:
Self jumpstarting
Isolate parked/camping electrical loads to one battery
Charging to aux battery while parked with sun using accessories (fridge, usb, radios)
Force combine batteries during winching or compressor use
Ability to float charge both batteries to 100% when parked outside
No need for occasional shore power charger to top up batteries
In the odd case of 1 battery failure, I can still start and drive the truck with other battery.

There is definitely a bit of redundancy and complexity to my setup since I added the Redarc after I had the Blue Sea ACR. I did that so I can properly charge my agm batteries. Solar is rad as well since it constantly keeps the batteries full on days I don’t drive or if I feel like using power, it’s no worries.

Sadly I had to buy a complete set of wheels from the local skate shop. Those things are pricey!

Would have been awesome if the the story included: “took the Vision Blurrs of my old Caballero (insert your old skateboard) Pool deck!” Yup, I confess, mid 1980s to early 90s skater here. Got my license in 91 so it’s been cars since then.
