Probably a dumb question and unlikely, but can one of the new 20volt Lithium Ion batteries fit into the 12volt line of tools? I'm tired of having 4 different brands with all the different chargers and want to stick to one system. So far, I'm narrowing down to Dewalt and Bosch.
I'm interested in getting both a new 20v Drill and Impact driver, but would like the flexibility to use the batteries in some of the 12 volt lines tools and accessories.
