Maybe somebody can help me with the following question on batteries: I
have several batteries which I have to charge from different sources.
I have solar panels on the roof of my RV, 2 by 3 meters. On a sunny
day, they can charge maybe the equivalent of a 100 ah battery. But if
I run appliances during the day, or it's cloudy, the charge from the
solar panels does not carry me through the night. So I bring reserve
electricity with me in the form of several batteries that I fully
charged at home. I understand that it's unwise to combine different
batteries in a bank because of different charging parameters. But I
wonder whether different batteries of the same voltage could be used
in a parallel circuit for discharge cycles only?
What I would do is this: disconnect the solar controller in the
evening, then do a parallel circuit of the half charged battery
usually connected to the solar panels, plus 2 batteries at different
charge levels remaining from charging at home. Then I would have
enough electricity through the night, and an additional rationale
would be that none of the batteries get fully discharged.
