Having sold my 2019 Sub, I am passing on my dual battery setup using GM parts and the HellRoaring BIC-100M. In this setup, the driver's side battery is purely a starting backup battery. When the truck is running it is being charged if necessary. When not running, the driver side back-up battery is disconnected. Everything runs off the primary passenger side battery. If you run the passenger side battery down having hooked to your camper, or by falling asleep listening to your tunes, you just flip the switch and the driver's side battery will start you up. I previously had this in my 2011 Suburban, and it can be modified to work in the previous model with a modified B+ cable length. I will also send several dual battery stickers AND my upfitter connector from which I obtained switched power for my dash cam.
What is included:
GM Aux Bat to Block B- cable
GM Aux Bat Fuse Housing
2 Gauge cable from Aux B+ to HellRoaring BIC-100M
2 Gauge cable from HellRoaring BIC-100M to Starter B+
HellRoaring BIC-100M
BIC-100M Instructions (if I can find them, otherwise get from the HellRoaring site)
3 or 4 Dual Battery Caution stickers
The Aux battery hold down
Pics and videos I took of the system when I uninstalled it.
You may have to buy the Aux tray as the one shipped now doesn't have the hold down bracket and is not tapped for the hold down bolt. But you could bend a bracket easily, and drill and self tap a hole as well. If I was going to do it again I would probably follow this route. But the trays are readily had and inexpensive. This is a relatively easy install. Hardest part is taking off the front tire to get to the starter B+ stud.
An upfitter connector for the upfitter panel in the driver footwell with instructions. I had this connected to my dash cam with the wire running hidden up through the A pillar and headliner. I have pics of that setup as well.
$50 + shipping or $50 with free local pick-up. Cincy-Dayton area.
PM me and if we have a deal I will mark this sold.
