As to lithium batteries yay or nay. Looking for a lighter drill for med/light duty. This 62 yr old with a dicey shoulder doesn't like holding a 18v nimh makita (6lbs) for doing the job. Gee, you go online and look at the feedback on amazon and you'd think that between the dicey batteries,the wobbly and poorly clamping(the bits)chucks that all the makers can't make a decent drill (and impact driver). TIA Pat
