General charging question
I'm curious about the possibility of "back flow" in a charging system, given the multiple charging sources on most RV's (shore power, generator, alternator). What keeps one charging source from potent...

Perdy simple if you ask me,.....
Their all charging a 12v system, its all about voltage.
A charging system can't tell the difference between a battery, or another charger, except the difference in voltage. If you have 1 charger connected putting out 13.8 volts, connecting another charger will see it as a full charged battery, and just go to float,......or if capable of a higher voltage, may raise the system voltage for a regulated time, shutting down the other charger completely. Equal voltage chargers may even share the charging equally.
12-15 volts is a 12v system voltage, whether its in a battery or another charger, it really doesn't care.
