This topic is really for another thread but personally, I think A123 is the best battery to come out for R/C.
LOL! Folks have said the same thing each time a new battery technology came out!
they don't lose power over time, don't catch fire like Lipos do.......I could easily get 10 or so flights on the plane before I need a charge.
LiPo's don't catch fire unless you force that to happen. Too many chicken little's crying the sky is falling, nothing more.
Li-Ion's also don't catch fire, maintain voltage curve just like A123/LiFe's do, and they generally weigh less than A123/LiFe's.
Only negative to Li-Ion's is the need of a regulator. But with NO need for a NEW A123/LiFe charger, using chargers we have that's already LiPo/Li-Ion capable, for many it's better to go Li-Ion.
Just think, when the next battery technology comes out, we get to go through all this all over again!
