You can probably disable the Genesis solenoid by simply unplugging the connector on the Cole Hersee charge controller. The solenoid will never energize and connect the two batteries that way. If you ever need to combine the two batteries because the starting battery is run down, just plug the charge controller back in, and use the start boost button.
The DC-DC charger input power wire (from the starting battery) does need to be on its own ignition activated solenoid though, so it will switch off when the engine isn’t running. I’d put a fuse in the ignition activated wire close to the solenoid in an in-line fuse holder, and use that to disable the DC-DC charger in the event you need to combine the batteries.

Connect the input to the start battery. Connect the output to the accessory battery.
Remove the other charge control relay.

It was partially my intention, yes. But also, it still doesn't address the need to properly charge the starting battery, since the OEM alternator will not do that properly for these types of batteries.
What is the purpose of connecting the DC to DC charger input to the Genesis output? Why wouldn't I just completely remove the Genesis isolator? Trying to learn here...

disconnect the second battery, connect the dc-dc charger to output of the second battery wiring from the genesis kit, and connect the output of the dc-dc to the second battery and that should be it.

Any idea what the potential repercussions might be? Everything seems to be working correctly with the battery sensor disconnected, other than the voltage just sits there at 14.7V instead of fluctuating with engine speed.
At a continuous 14.7V, you will kill your battery in MONTHS !

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. )
