Conditioning/"formatting" new batteries: update in 1st post

Mex, somewhere north of Mammoth and south of Tahoe -- we will be moving around, looking for high altitude boondocking to escape the heat. And someplace we can camp in the shade but then put my new panel in the sun. And then I will proceed to bore my poor wife to tears while taking readings off the panels and the batteries while experimentally moving the panel around to find the best angle.
