Yes!! however you havent specified which batteries you intend to use. Remember that a USB power pack is merely a battery at it's heart.
As several have alluded to you can run directly off the batteries and now the RPI2 has a switch mode regulator it's less fussy than before but still all 5V powered sections of the RPI would be at risk of damage at excessive voltages say much more than5.25/5.5V or just not working at low voltages.
You will in practice require 5Volts from some where in the case of batteries this could be 6V(4 AA bateries for example) or more into a decent switchmode regulator.
We would need to know your intentions for the device including what batteries you intend using to make more specific suggestions.
Personally I would use a USB battery pack as they are cheap and powerful as well as been simple to use
