I do a lot of BBB work with 1S, 2S, and 3S LiPo packs. Remember, the lower the voltage the higher the current requirements are going to be on the batteries. Pretty sure that I've run from a 2xAA alkaline pack but I know that the LiPos can easily supply the current. During boot I've seen spikes up to 1A at 3V - which is typically where you'll see the brown outs. I'm using a buck/boost regulator that allows for a large input voltage range (3-14V).
