This is the battery tray that I am using. You will need a Redarc BCDC charger to keep the spare battery charged correctly.
I spent alot of time researching this and then spent a bunch of money I didnt need to in order to get it to do what I needed it to do.
I could literally write a story about stuff that I researched and learned about this. Do you really want to go into that kind of detail or do you just want the
cliffnotes?

It's a lot of work, but a full write up on what you've learned for future reference would be a huge benefit to T3G. If you're willing to write it up, I say go for it. 👍

Ive been running a dual battery setup for a few months now. Currently im just using the odyssey battery as my aux battery, I do have plans to replace the starter battery later this fall to match the aux battery, but so far no issues with the current battery setup.

OffGrid makes a great mount, I had some challenges getting it to fit for some reason but it worked out in the end! I also am using their mount for the redarc bcdc1225 system underneath the starter battery. I do have plans to change the charge from the alternator to get up to 14.7V with OVtune's new VFtuner (currently running 2.0), which will allow me to fully charge the aux battery instead of the normal oem 13.4V (not really a full charge on the aux battery).

I went the lazy route and bought the full off grid system. they weren't offering Redarc when I bought (been running it awhile now). interested in VF tuner after he releases 2.0 for it.

I went and purchased the upgrade to VFTuner yesterday. I'm awaiting my codes to activate. Looking forward to a few simple features to add to my build like increasing the voltage my alternator produces to 14.7 to keep my AGM battery healthy.

I'm a cheapo so I installed a "Battery Doctor" isolator. I used a SDHQ Aux Battery Tray assembly with SDHQ battery hold downs for both batteries......included with tray assembly. Then pieced the rest of it together using circuit breakers, terminals, and wire that I had on hand. Going on a year and a half, running this setup. So far, so good.

I am very interested in this. Do you have any info on it? This would make it so my main battery charges at 14.7 also.

Yep. Basically OV (Orange Virus Tuning) has released their new VFTuner software allowing the user to change many parameters of the vehicle. ECU tuning, transmission tuning, and even auxiliary items such as increasing the voltage put out by the alternator. Pretty cool stuff. I just ordered the other day and will be doing some of the changes as soon as I have the full software setup and accessible.

For those who already have the OVTune software n their truck, you can order at the reduced "upgrade" rate via this link.

Oh yeah. I had the basic OV tune when I got my gears installed and I was a little underwhelmed with the amount of change I saw with the gears. Then the 5.29 specific gear tune was released and once I installed that I saw a massive difference in performance. The factory tune, and the factory gearing OV tune are both set up to shift way too early for the 5.29s.
