I'm getting pretty sick of my old cordless drills and multi-tools, but I'm not buying replacements until these next gen lithium cells come online. How long until we have product lines of tools using combinations of single Tesla battery cells? Will Dewalt come out with a line of tools using to take Tesla tube cells, or will we just recharge their proprietary batteries off our solar arrays/Powerwalls? I'd like to see a scenario where I own maybe 60-80 individual Tesla cells, a 24 cell charging station in my garage and a whole series of tools that are battery operated by any number of cells. The drill takes 4 cells at a time, the flashlight two, the vacuum 12, the lawnmower and snowblower 20, etc.... Just like cars, more(if not all) household tools will be electric soon so it'll be even more logical to have a universal and interchangeable power source. Why not the normal Tesla cell? Is that likely to happen? Are they powerful enough to mow a lawn on a say 18+ cells?
