I think it would be better if the two Odyssey’s were separated all the time, except when you need them for emergency starting. That way, a DC-DC charger could be installed between them, and it would be simply another load on the starting battery and it’s charging system. But then you would need to make sure all of your “engine stopped” accessory loads are connected to the second battery. )
Yeah, that's not really a possibility without rewiring the entire Jeep, which is more than I want to try to take on.
I'm starting to think my best option is just to put it on the charger a couple times a week to keep the batteries topped off so they don't sulfate.
I might also look at installing a switch for the intelligent battery sensor, so I can enable and disable it manually. That way if I ever need to ensure my batteries get charged by the alternator, I just disable the intelligent battery sensor, which will trick it into doing 14.7 V until I enable it again.
