When leaving a campground with partially drawn down house batteries, the engines alternator will slowly recharge them.
Can I charge those batteries faster by starting the in house generator at the same time charging from two sources?
So. . . . . I've gotta ask the obvious (at least to me) question. Why are you leaving the campground without fully (re)charging the batteries? (assuming you have shore power and camped overnight)
Simple answer. NO. Two charging sources will compete with each other. The one with the highest charging voltage wins. It tricks the other charging source into thinking the battery voltage, or state of charge, is already high enough so it tapers the charge off.
