I am new to this engine but to solve this problem could you put an electric clutch pully in so that when you are looking to use engine for propulsion you could disengage the alt/generator? In this I mean have a normal smaller alt running base systems and a larger gen unit on a separate drive with clutch pully for extra charging.

Are you looking to boost your amperage? I've seen a DC to dc amp booster that I want to try. Hook alt to it than it to batteries. I've seen 20 40 and 60 amp versions.

A DC-DC charger cannot really do much to boost the power output from the alternator, the laws of thermodynamics come into play.
1. You can't win
2. You can't break even
3. You have to play
At best they act like a MPPT solar charge controller and get a *little more* out of an alternator by converting a lot of amps but sagging voltage into a little less amps and a little more voltage. The tiny gains would not be even close to being worth what they cost for that purpose.
I very much plan to use one of these to charge a lithium bank when I get one, but for different reasons including limiting the power going to the bank and using the correct charge profile.
