Question Isolating coach batteries from house batteries.

[lostinfla]

Since I've changed to lithium for house power, I've been toying with the idea of not using the engine alternator to charge the house bank as it will last much longer than the daily drive to power what we use before plugging in again, then the inverter takes over the program. I have a lithium BIM installed and wondered if removing and isolating the coach line side from it would do the job, or eliminate it all together. What say ye?

I, too, am interested in the replies and how difficult will taking the charge away from the alternator?
