My setup is in a 2020 Sprinter van with a large (700ah) lithium bank of batteries used as the 'house' battery for all of my loads. This is used as a camper van and a common use case would be to park somewhere fun and not start the engine for days.
All the coming/going from the van through the day triggers the van dash computers to come on and it puts a beating on the starter battery. It isn't uncommon to get a low voltage warning after a few days of not driving in this scenario.
I want to setup a battery maintainer that I can just set and forget. All of the devices I have seen for this use case run on AC power, but I do not run an inverter 24/7 so my solution will need to be DC.
I bought a Victron Smart Orion-TR 12/12-18 charger for this purpose. It is wired to charge the starter battery from the house and only gets activated when the van engine is OFF. However I have read conflicting information online about if it is healthy for the battery to leave this on 24/7. So I currently manually flip this charge on/off using breakers when I think it is appropriate.
What I am hoping to gain here is confidence/knowledge on two questions:

What I am hoping to gain here is confidence/knowledge on two questions:
- Is it healthy to keep an AGM battery ( Specifically this battery ) on float all the time. Basically anytime the van is off the charger would activate, and in most scenarios I would expect it to very shortly end up in the 'float' stage of its charging profile as the vans own charging system would have just finished charging the battery.
- If it is healthy to keep a battery on float, are there any tweaks I would want to make to the float voltage in the Victron profile.
