Started with the kdrill clam plate setup and a dewalt 996 with 5ah batteries. Got a 9ah flexvolt battery the next year, and it worked a lot better. The 5ah batteries always seemed to make the auger catch at the bottom of the hole, The flexvolt seemed like it produced a touch more power. I have since gotten a lite flite and don’t have the issue with either battery combo. Even with he flexvolt/kdrill combo I could barel use up the 9ah battery in a day.
