I currently don't have a way to keep my starting batteries charged while my rig is sitting. I have plenty of solar and battery capacity, but I haven't figure out how to transfer energy from my battery pack or solar to my starting batteries, since the house system is set up to handle the lithium pack.
Currently, my best idea is to install a Victron Orion 12v 9amp DC-DC charger and set the output voltage to 13.4v. Then control it via one of the additional outputs of my SBMS0 so it's only active when my house pack is at a set SOC, maybe 85-90%.
But I don't know much about lead acid batteries. Will always holding them at a set voltage hurt them? And will the Victron unit get damaged when I start the truck and the chassis side is sitting at 14.6 volts from the alternators?
I've included a simple schematic showing the major layout of my electrical system for reference.
Edit: Increased size of schematic.
