I ran out to Boyd to test out a battery cable I made to connect my drill/driver to a larger 12V battery for more juice, so I can drill more holes with my auger attachment. The ice is not terribly thick there, so it wasn't that big a deal, but it worked fine. My drill is a 14.4 V, though. I have a feeling, it would work better with one of the newer high-torque 12 V models. I have access to one I'm going to try to bring to Elevenmile to try with the auger.
