These cells look fantastic... they can discharge at 50C and only get to 34*C (93F), wow.
-They have even better cycle life than A123 cells.
-More power than lipo, possibly by a long shot, but W/kg not known.
-Safe like A123's
-Perform just as well at -30*C as they do room temp.
-Energy density appears to be the same as A123 tech, is the only downside.
-2.5V/cell terminal voltage
