Parasitic Draw on RV?
I am getting ready to add a small solar system to the top of my 5er to keep the batteries topped off when we leave the camper at the lake for extended periods. My wife and I generally pull the camper ...

yes, if the batt is full with no loads then at first light the voltage will climb to abs voltage and it will take very little power to keep it there (lots of off time). During use you may draw the battery down enough so it goes back to bulk charging (no off time) and once it gets back to set pt voltage of 14.?v the off time increases.
Others may suggest that the current tapers as the battery charges but what actually happens is the OFF time increases so that the average current over time tapers.
