The overlay would be nearly mandatory in my opinion - otherwise why graph the data? Can the data at least be output as a text file to graph it in excel?
One more suggestion I would have is the ability to do 2v and 4v lead. Yes, I have a 4v lead battery. It would seem an easy couple lines of code to allow it?
That is a good observation about testing packs. The PL-8 is a great tool for that. In addition to watching the charge and discharge curves, you can hook this instrument up when running a motor, for example, and monitor the pack to see how it reacts to actual loads.
I can't answer your question about overlays, though I agree it would be a good thing to be able to compare subsequent cycles. We will put that in the hopper to ask the engineers.
And, yes, the PL-8 has Preset adjustments for Lead Acid charging from 1 to 12 cells. Does that do it for you?
Keep these good questions coming.
