5th Gen 4Runner Electrical Management System/Dual Battery

I wanted to share a project I've been working on for a few weeks. It's not quite finished yet, but it's to a place where I'm comfortable sharing. Things left to do include replacing the starter battery with a group 35 odyssey and getting 4x 50w Renogy Eclipse panels mounted in series to a slide out under my roof rack. The slide out will be controlled off a starter relay system and a linear actuator will extend and retract the panels with the cars ignition out over the hood, of course there will also be a manual override. The panels will also be removable so they can be set up remotly or angled to track the sun.

I have installed the Shrockworks dual battery tray, vacuum pump relocation bracket, and ACR/Fuse tray. In the tray I have a Odyssey Group 25 65ah battery, they are automatically joined using a Blue Sea ACR. All of the main cables are 1/0 and were purchased from Custombatterycables.com for the most part they already have the cable lengths/terminal sizes figured out. Most smaller cables are 4 awg. The battery cables are protected with dual 400a ANL fuses in Littelfuse holders. I can't thank [MENTION=135780]krayton444[/MENTION] enough for bringing the custombatterycables.com to my attention, the fact that they already knew what cables/lengths and terminal were needed for the dual battery 1/0 awg wire really saved me a ton of time!

I made a custom circuit breaker/fuse panel out of 1/4" plastic and attached it to the top of the battery tie downs. Everything is capped for safety. Circuit breakers are for 1. Under hood Blue Sea Fuse Panel 2. Constant 12v to the rear blue sea panel 3. Ignition hot 12v to the rear blue sea panel. The 200a PAC controls the ignition hot feed.

Shrockworks vacuum relocation bracket made a great place to mount my Victron BMS-702 500a shunt. Hopefully a ARB twin compressor will sit atop all this shortly.

NOCO Genius 110 input plug. This feeds the CTEK 7002 AC/DC charger and the rear shore power. The ARB is always connected to 110v and 12v, when 110v is plugged it is automatically switches over so the CTEK can focus on charging the batteries not running the fridge. (Thanks for the NOCO plug location idea [MENTION=56922]NoOneBetter[/MENTION])

This is the ARB on a Easyslide 150 drop slide, behind it is the RAGO Modular Storage Panels (they are awesome!) (Thanks [MENTION=143767]maddiesel67[/MENTION] for the Easy Slide idea)

This photo shows the rear circuit breaker, Blue Sea dual buss fuse panel (12v con/ign./ground), Victron MPPT 100/30 solar charge controller (panels on order), and shore power strip. You can also see that I'm using a key retractable reel to automatically control both the 110v and 12v fridge cables. It works beautifully! Key-bak

Finally, in the cab I have a Victron BMS-702 mounted along with the handy bluetooth dongle installed. This lets me check the batteries from outside the vehicle on my iPhone. I used a cravinspeed steering column mount. (@LOLSNOW brought this gauge to my attention, thanks!) There is room for another gauge, (hopefully a Magnuson Superchargers boost gauge :Wow1:). You can also see the Blue Sea ACR switch just peaking through the steering wheel on the bottom right.

I also whipped up a custom dual battery voltmeter that fits in a switch blank in the overhead cluster (Idea belongs to [MENTION=123786]Keith_PDX[/MENTION], awesome mod for <$15)

Finally thanks to [MENTION=137555]Sleeter[/MENTION] for brining the HKB voltage booster to my attention. This little alternator fuse bumps my alternators voltage about .5-.7v higher than factory which keeps the Odyssey happy and lets the ACR work in the stubborn 4Rs. Thank you to @dwh and @DiploStrat for sharing your knowledge and answering stupid questions.

Jerad,
Whats next a Flux Capacitor? L.O.L.
Nice clean job. I especially like the drawer system.

I wish! My next project is a trailer! Put a deposit on this bad boy today, it's blank canvas. I can't want to start designing it as soon as I get hit home!

[MENTION=15690]jerad[/MENTION] ...between your electrical setup, your rear storage system, and that TB Trailer... You are quickly becoming my DIY hero. :thumb:
 
Noob question: for the BlueSea dual bus fuse panel in the rear, where in the 4runner do you wire the positive feed back for ignition only power and where do you wire back for the ‘always on’ power?

Does the Shrockworks vacuum relocation set come with the hose or did you have to go out and get one? If you purchased it yourself what type did you use? Currently planning to move my pump and curious on what you did.

It comes with everything you need. You cut and reuse pieces. Not a super hard install just time consuming. Instructions are very good as well.

A few questions

Can some info or wiring diagrams be provided on your shore and solar power setup? I would be interested in what is auto switching between shore power and solar. What gauge wire gauge did you run from battery to the mppt controller?

I like the concept, I am getting ready to install the off grid engineering dual battery kit and I am interested in working in both shore and solar capability.
 
What amperage does that charger output? Do you use that just as a maintainer or to run/charge up the system?

Like the setup though!
 
THAT'S SOME NICE ELECTRICAL WORK !!! :thumb:

YEP... it fits nicely!... :thumb:
You will need a remote airchuck due to height restrictions, but that's an easy lift'...

And even if you went with the reservoir relocation...

Digging up your thread...

When camping in the rain, did you have problems with the NOCO Input Plug if you connected to shore power and it rained?

I like the location but if it fills with water while the cover is open and plugged into shore power....
 
That seems to be a lot of work for a dual battery setup. What I have is a portable dual battery setup. In my case, the only thing i did on my 4runner is wire a 6 guage positive wire from the battery to trunk and connect my everything there, negative was attached to the body. battery, charger controller, outputs and inputs, fuses are all in one box. this way, i can use it for something else in the house, for the 12v fridge and stuff. check my youtube video here. https://www.youtube.com/watch?v=ZbVtZvK-f9s&feature=youtu.be
