That is correct. Remove the charge source once you've reached full charge. You may want to check with Stark if the BMS (battery management system) does that for you. The BMS I'm getting from Electrodacus, does that as part of the management system.
I've been looking at my current 2xAGMs, solar, and IOTA wiring and planning for my lithium/bms arrival. I'll need to do some changes the way the IOTA is hooked up to the system. The IOTA currently is wired directly to the fuse block. There is a on/off switch that connects/disconnects the AGM battery to the fuse box. The IOTA charges the AGM's via this connection to the battery. That is why, if you are plugged into shore power, the battery will not charge unless the switch is on. If off, the battery is disconnected from the fuse block and therefore not receiving current from the IOTA but the rest of the camper is still powered by the IOTA.
A little complicated but this is the best I could figure out. If your bms shuts down the charging, then your okay the way you have it, otherwise you may need to disconnect the shore power once the batteries reach 100%.
