Grover, I believe you're on the right track if your new batteries have a built in charge controller. As far as alternators not being able to fully charge house batteries, that's non-ยข. A steady charge at 14 volts for a full day of driving will fully charge lead/acid house batteries. If you are concerned about over heating you alternator with Li batteries, why not put a temperature sensor on the alternator before and after the battery change and see what happens. I see so much hype about burning out alternators but no solid evidence.

1. 14 volts will NOT fully charge a lead acid battery in a full day of driving. It is unlikely unless there is a dedicated alternator that 14 is available for the entire day.
2. Victron has a different opinion that yours on burning out an alternator.
