Nope, for raw ampere hours to weight ratios, Lipos have it over the A123 cells. But, A123 cells have a very long life, and have zero fire hazard. Some of the Lipos can be fast charged, but this has been true for the A123 cells since they came available.
My three 6S2P A123 packs each have over 200 flights on them, they are three years old, and have the same exact performance as when they were brand new. I'm pulling 50-60 Amperes out of them at full power.
