As indicated on the silk screening of the front panel of the USRP(s) they are
powered by 6V DC @ 3A (Center pin is positive, outer negative). It's fairly
easy to find battery solutions that meet this criteria directly without using
the AC adapter. I have built light weight Li-Ion solutions for USRPs also, you
need to take a little more care with these, there nominal voltages tend to be
significantly higher than 6V and the details of what USRP/daughter board is
being used can be important. Stick with a lantern style battery or gel cell if
you want to keep it simple and safe.
