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...

Originally R32 (point 1) connects to the filter capacitor located after the PWM stage. That voltage should be 13.7V. I added a 100 ohm resistor that now senses voltage directly at the batteries. The new diode is for safety. Should the bell wire open up we lose regulation and the converter would increase voltage to unsafe conditions. Should this happen, the diode conducts and limits max voltage to about 14.4 V. The circuit is bullet proof. ;-)
The mod more than doubled the performance of the Parallax 7345.

Just as a matter of interest, I can see you added a diode, a 100 ohm resistor and the bell wire to do the remote voltage sensing. They connect at point 1 to R32 at the error amp. What was originally connected to point 1 and the input at R32? IOW, how did it originally monitor its own output voltage before you added the remote sensing wire?
