Looks like, finally, we will be getting samples of Lithium Sulfur batteries-new plant! And lithium sulfur should be around 2x energy dense as lithium cobalt. Also, safer.
These cells will need 2 in series for 4 volt. Maybe, 3 series for true buck switching driver for 95% efficient driver, as opposed to the 70% amc7135 linear buck.
They look to me like the ideal cell for headlamps and left wrist lights (for left had use). Probably could also shrink the edc.
(As noted, and expressed before, I hate the runtime and lux of typical edc.)
