@rosedale: why? To confirm what I said? If that's the case, there's no suspense at all: higher C rating means lower IR, means less sag under load, means higher operating voltage when full, means more power output... means hotter running device. But at the cost of shorter capacity (it's one or the other you can't have both) If you want to go this route try the LG HB6. Or well, don't, I did it for you already and the capacity is ridiculously short, maybe 1.5 sessions with my usage pattern vs 3 with the larger capacity cells. But oh boy does it run hot... for a very short while heh!
