I am drawing 12 volts at 1/2 amp for 6 hours a day off of one 12 volt car battery battery which is powered by a 2 amp solar charger voltage goes to almost 14 volts when charging I then added two more car batteries voltage is under 13 volts when charging with the same load is it better to use only one battery as voltage is higher when charging then with three or does this not matter?
