Note that this is coming straight from a SW guy, but since you don't care about being competition legal, and since the cRIO doesn't require 24V, but instead needs a minimum of 9 or so volts, another approach is to use a second battery instead of a PD. The cRIO draws very little power, and in the past we've run it for I believe four hours on a small lawnmower battery.
