I can say that it draws 2.5-4W, depending on load
I think my rpp has a slightly defective power supply chip,
for the 1st few days all I got was a flashing green light,
this is a 5V -> GRD connection. So, nothing worked... at all
2 or 3 different power bricks, then I hooked it up to my bench ps,,
and it will start to work at 7V, but not boot,,, maybe my bad ps chip?
I ran it for a few days at 13V, no problem
(the bricks all had a 1 V ripple, 11v to 12v, the brick that works has a 1/4 V ripple)
The schematic says up to ~18V, so you have some headroom
So... why not 3 lithium bats in series, this might give you 6-8 hrs run time
(depending on C of bats and what you have hooked up)
There is a direct connection to pcie port, so maybe not overvolt anything in it
