PD or Iota for my upgrade?
I'm thinking about a converter and battery upgrade. The batteries will be wet cell lead acid 6 volt Possible T-105s or the 230AH, EGC2 from Sam's club. I'll probably go for four. (Does nayone have...

I'm assuming you meant Voltage "/" 10.
I multiplied 14.5 volts by 10 to display it as 145 - so the number on the graph is "Voltage x 10." You are correct that you need to divide the number on the graph by 10 to get the voltage. :)
I don't see much sign that the PD is doing anything particularly odd.
1) I'd like to see what effect changing the input AC voltage has.
2) It wouldn't hurt to bump the boost voltage to the spec of 14.6 (up from 14.55) or even up to 14.8, which is what is specified for Trojan flooded cells. Studying the circuit diagram and circuit board, I can see where that change would be fairly easy. If the Iota is using 14.8 as the boost, that would give it an edge when it's in that mode, but I like the PD's capability to manually override and set the voltage/mode.
3) I'd like to explore the automatic boost mode more. The PD sets a flag that tells it it entered boost manually, and that limits the boost time. If it enters on its own, that flag isn't set and it behaves differently.
4) I also wonder if 1/0 cables versus 4/0 would make much difference, particularly in that 3-4 hour region.
5) If I get a chance, I'll measure the voltage drop across the cables next time I do this. Right now we're prepping for a long trip, but I couldn't resist grabbing some time for this first test.
