Finally finished the Dual Battery setup. I researched a few different people's builds and watched dozens of videos, read through lots of forums and tried to do my own research as well. Thanks to another forum member for some guidance and providing some info as well. I'll keep from naming him just in case he wants to remain out of the spotlight.
I stuck with the OEM LA battery for the starter battery. All the rest, is the list of items I used; sans multiple trips to hardware store for different bolts, nuts, electrical components, etc.
UPS, FEDEX, and USPS were showing up on the daily for about 3 weeks straight while gathering all the components.
- C4FAB battery tray
- Duracell Deep cycle Marine 70AH AGM
- REDARC 1225D DC DC charger
- REDARC 40amp fuse
- Two 40amp resettable circuit breakers (blue sea)
- 4AWG terminated Battery cables (ordered to length) for under hood and from aux batt to rear power box
- SDHQ battery terminals
- NOCO genius GEN2 (20amp / 2 bank)
- NOCO Extension for shore power plug-in
- 9"x6" sealable hard plastic box (power distribution box)
- Victron Battery monitor (BMV-712)
- Voltmeter (blue sea)
- USBs (blue sea)
- USB + USBc
- cigarette lighter style 12v socket
- Anderson power pole connector
- 1/2" 12x24" black plastic starboard
Still waiting on Dometics DC hardwire kit to add to power box, fridge plugs into socket on top of box for now.
This was my attempt at combining a few things I saw from different builds. I'm no expert, and could've had some cleaner wire groupings, but didn't want to mess with cutting and re-terminating battery cables. I chose to make the power distribution box removable, so it's connected by an Anderson connector and hangs on my MOLLE panel in the rear compartment. I had to get somewhat creative at mounting the NOCO, and with little real estate under the hood, decided to mount it on top of the fuse box hard mounted to a plastic base. I left enough slack to rotate it up to easily access fuses and relays. Seems to work just fine. I'm pretty happy with it, and will most likely add solar within the next year or so.
