Jazz 59... I think what Jmo says is what Ted might have said to me in the past regarding moving up the Tesla SC pattern. I have a very similar cable selection, so I am interested in what you find out... perhaps a call to Ted at SR would throw everything into sharper focus. If you do call, let us all know what you learned!
It's also my impression that the Tesla PowerCell at this point in your system pattern might be an important alternative.
