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...

Go and measure your PD. Take a look at the error amp circuit.
I understand what you're suggesting, but the true "error amp" is inside the UC3846 Unitrode chip. There's nothing to look at there. There are really multiple error amps - current and voltage. They receive inputs from circuits that monitor the voltage and current.
The voltage monitoring is a pretty simple circuit, but the current monitoring is more complex. Still, it should be possible to check the inputs to the error amps in the Unitrode to see if it's getting the wrong signals from the monitoring circuits about current or voltage.
Before doing that, however, I need to actually see a problem. The reports I've seen about problems relate mostly to the AC input power to the PD, and the most controlled tests show that with good power it works as designed. If there is truly some kind of odd interaction between a battery and the PD, I would need to be able to see it before I could diagnose the cause.
And someone should kick me. I'm thinking about skipping a trip to camp by a river this weekend - so I can test my new battery and charger system - that I want to work optimally - so I can spend more time camping by the river. Where are my priorities??? :)
