Playing with the 10440 Li-ion battery and chargers and rates and

true, it then no kidding even beats the Quark X AA 1x 14500 on High-mode.

the only downside is the runtime: the iTP A3 XP-G R5 runs only for max. 3 - 14mins before it reaches the 2.75V mark (protection PCB trips!). The runtime depends on the temperature of the little torch (and its 10440 cell). With optimal conditions you get the 14mins of runtime, i've clocked it.

Since the iTP A3 doesnt support protected 10440's (well, you need 2 rings to make the Protected grey Ultrafire 10440's 47.1mm work reliably in the iTP A3 Aluminum version) the only practical sense/use is imho to show it off in front your folks. That's actually a very good and sensible practical use hehe
