Being lithium technology is so new I don't expect a lot of feedback on this question. I plan on putting (2) 12v 200ah prismatic lithium batteries in my boat in the next month. From what I understand my Xantrex Freedom Marine 20 inverter/charger will work with them on shore power but my 105 amp Fleece Neville alternator will most likely toast! So me question is should I get this fancy $2k Balmar 200 amp alternator, regulator and serp belt? I could probably just get the regulator but charging would take a long time. I have seen other high amp alternators but not many regulators. Or would getting a Victron DC to DC charger make more sense?
