A tester claims about 12 hours battery life with
motion M1200 (P3M 933 MHz), continuously downloading
(from MSDN hehe) through wifi.

****Report said it was ~ 3.4 lbs, which is believable,

max60 is about the same, except it's 6,6Ah (95Wh), is
probably really "1.08kg or 2.38lbs", and charging time
is 3 ($350).

Seems easier to use than NiMH, but you might still
need a dc-dc transformer, and its size isn't exactly
in the small range.
