Diver300:
I'm using the comparator, not the ADC for voltage control. Microchip also recommends a 10K input impedance limit for this function.
Looking at the original Walther schematic, that I posted earlier, the voltage divider consists of R8, which is 10 meg and R9, 300K.
As I recall, the battery current draw with charged capacitor was 28ma. My simulation suggests initial current draw with discharged cap can be 2.2 amps for 1millisecond. This suggests that keeping the pulser on may allow the power supply to function at a voltage, below which, it is able to start from zero charge.
I haven't experimented with cap front loading an ADC. I'll look into it.
