Lithium SuperPack drop-in replacement feasibility

Hi, I've been reading though all the posted questions but can't find a clear answer.

I'm considering replacing the current AGM house bank on my boat with SuperPack batteries, and I'm trying to understand what it would involve.

Below an attempt to visualize my current setup:

I understand that I'll have to replace the shore charger for a Lithium one, but beyond that, is there anything else I would have to replace/modify, or will the SmartPacks be a simple "drop-in" replacement?

My main doubt is:

Since the BMS is integrated, what will happen if the batteries are fully charged and the engine/alternator is running? Is there a risk the BMS will trigger the over-charge protection and disconnect all the loads (e.g. loosing plotter and instruments when approaching an anchorage/marina)


Any other suggestion/input is highly appreciated, like: does the Argo Fet still make sense with the SuperPack, or should I replace it with an Orion-Tr DC-DC charger? Do I need a separate external BMS to protect the batteries from overcharging?

Thank you!
