I have confirmed that even the first schematic I posted is perfectly stable with a good power supply. I still haven't been able to boot with the serial adapter power or 2x Energizer Ultimate Lithium batteries that run at 3.4v. Still seeing a huge voltage drop on the batteries. Not seeing a ton of amperage, but not sure its reading right. Seeing 200mA draw max.
