I don't know if the lithium powered drills are lighter per se, but there are a wide range of models of powered drills available. Some are much lighter than others, but you might as well go to Lowes or HD or somewhere and pick them up and see. If you aren't driving screws into pressure treated wood, I would think the lightest model you can find and hold would be up to most limited duty tasks (anything it can't handle you shouldn't be doing probably).
