RE: On the workbench tonight....
Joe, I think that your incorporating two batteries of two different voltages and capacities is a kind of "first time" for this forum.I know that some fellas run two batteries in paralell for highercurrent capacity,but of course they use batteries of the same capacity and voltage.In your example
though,you were able to employ two different capacities and voltages,each one assigned a different circuit.I have neverseen that arrangement used on this forum before.Good problem solving,Joe.
