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...

We agree on the issues in regards to the PD. I don't however believe you can fix the problem by modifying the PD front end. "By "front end", I presume you mean the capacitor peak charge circuit. I believe the transformer is at fault. It doesn't have enough turns-ratio to output 14.4 at minimum cap bank voltage.
The minimum ac voltage the converter is supposed to supply full current is 105Vrms. That translates to a cap bank voltage of:
V_cap = 105Vrms * sqr2 - 2 * Vd = 152V - 2V = 150Vpeak
You want to operate at least 20V below peak voltage.
The minimum transformer turns ratio is:
N_min = (V_cap - 20V) / V_reg
N_min = 130V / 14.4V = 9
If you look at the PD patent, I bet you'll find the transformer turns ratio is higher than 9.
