Used my Ridgid/k-drill combo with 4ah battery for the first time last weekend. 8" auger through 10-12" of ice in about 12 seconds. Drilled 7 holes. Got home 5 hours later and was only down 1 bar on the charger. The Ridgid barely meets the specs for inch pounds of torque recommended. The Fuel is waaay beyond what is recommended. For no more than I ice fish, the Ridgid will do the job for me just fine. I believe I got the drill/impact combo plus two 4ah batteries a couple years ago for like $185. I carry the combo around at the chuck on the drill. Can't see how that could possibly be doing any harm. There is nothing in the literature provided by k-drill that suggests carrying the combo around by the composite flights could potentially damage the drill. As mentioned above, get the $15.00 clam adapter for the ice anchors. Talk about making a PITA job easy...wow.
