What is the purpose of Bat Sense pins (BAT_SP and BAT_SN)? Can I leave them floating? Do I ever need to use them?

    Hi Morgan, 

    The purpose of the Bat Sense pins is to output direct battery sensing measurements to the user. If these measurements are not planned on being accounted for in the application, I believe they can be left floating.
