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.
that doesnt tell you ANYTHING.............
these batteries DO NOT DECREASE VOLTAGE UNDER LOAD UNTIL ITS WAY TO LATE
ive seen LiFE batteries be 95% discharged and still hold their voltage under a load, now once its gets to around 98% discharged the voltage goes from 6.6 to well below 4v basically killing any power you had to your reciever
that being said these things hold their charge much much better than nimh/cd, id expect that battery to still have 50% battery life
thats a little scary I guess I will have to keep a close eye on it and start doing a discharge on it and actually see whats left.
thats the only downside to life batteries (its actually a big + if you use it to your advantage) is that you cant test them on a amp/volt meter
also voltwatches will not be as useful
the only way to see how much they used is to discharge/charge them
