True true. Li-ion is nothing like Li-Polymer.......which don't hold charge well. Not that I have LiPo's in my MagLite, but Li put my brain immediately into RC car mode......which is one industry anxiously awaiting Li-ion technology. I think the issue still is current draw. Not sure if technology has caught up yet, but Li-ion could never supply the high amps needed for RC brushless motors a few years ago. I would imagine there is a pretty significant C draw with this saw motor, so maybe the tech has indeed caught up.
I hear you on the RC cars, thats where my brushless comment came from earlier. I am sure, like you said, the squints have figured out how to utilize lith-ion in a higher current application.
I haven't looked into the technology, but lets say you have a solar panel mounted on a pack that you wear. Keep your new lith-ion saw topped up as you work, as long as its sunny enough.
