I've been looking at the A123 cells as well, but there's something I don't understand. The way I calculate:
One A123 cell: 2300mAh, 3,3V, 70 grams. Hence, 108mWh/gram.
My LiPo pack: 4000mAh, 22,2V, 890 grams. So, 150mWh/gram.

Ergo, per gram the LiPo holds 50% more energy. Is'n't that what we want, flying?

Anyway, my budget didn't allow for A123s anyway, we'll see where I get with the LiPos. And I seem to run out of ideas to lighten the plane, but I want to get to 2500 grams take-off weight.

Cheers,

Hugo
