I must say I am impressed with the new LiFe batteries I guess there the same as the A123's. I installed an 1100mah LiFe battery in an plane that has 6 servos put 50 minutes of flight time on it, It then sat in the garage for several weeks when got the plane out today the battery was at 6.62 volts loaded with 150ma.

Im sold on them, I just dont like to take it out to charge it. I guess I will have to by some balance connector extensions. Then I could do it in the plane.
