thats funny.. does anyone race nicds anymore? i know the cheapo power tools use those. nimhs are in the mid level tools now and various lithium chemistry are in the high end ultra bad *ss construction tools. Because shaving a pound of battery weight makes "Joe Construction's" job easier on his back/arm/hand/whatever. Since just about day one (1) we've been running the same batts in our toy cars just with a shiny label.
