aa battery power DAC+PRO?

Hi Daniel,

I want to power my DAC+PRO with a separate power from raspberry pi. So I desolder the r14 resistor and connect the 2 pins to a battery bank with 4 2500mah aa rechargeable battery in series with each having 1.2v nominal voltage. I wonder if the 4.8 voltage is sufficient for this dac to work? Also because I am still using a wallart to power pi3, do I need to connect the ground pins together(and  how if needed?)

Thank you for answering the questions from a newbie:)
