I'm playing with the idea of charging our 200 AH house battery bank (two x 100 AH LiFePO4 BattleBorn batteries) using the current generated by the Sprinter alternator. My system diagram is here:

1. What are the practical limits to how much current I can expect to draw from the NCV3 alternator?
My datamb.com profile claims that we should have a 220 A alternator: "14 V/220 A ALTERNATOR"
Though presumably some / most of the current is needed for running various systems in the van. Is that a valid assumption?
2. I understand that one way to accomplish my goal is to install a DC-DC charger such as these Renogy devices:
https://www.renogy.com/12v-dc-to-dc-on-board-battery-charger/
Are they downsides to this approach?
Are there substantially superior dc-dc chargers which I ought to research?
3. Are there other / "better" ways to accomplish this goal?
