everydayflyer -> RE: a123 M1 voltage specs 3.3v or 3.6v? (2/12/2008 5:16:49 PM)

3.6 is the nonimal charged voltage however fact is shortly after charging they are closer to 3.45 .
Ni charge to approx. 1.5 so a 6cell is approx. 9 volts fresh from charge .
Non of this really tells the true story however. Volts delivered under load is more important.
A 2S A123 will maintain better volts under load and will maintain this voltage till they are empty whereas a Ni will drop in voltage and the truck will get slower and slower.
If you are lucky you may get 100 runs from NiMH if you take good care of them. A123s will most likely last 500 or more runs, perhaps a 1,000 depending on how hard you run them and take care of them.
I have a 3S A123 2300 mAh which has 225 runs in a Mamba max Powered Rustler and it still delivers over 2100 mAh. It has been rn flat every run and I have always fast charged it and stored it fully charge at shop temperature. Not the best care at all.
I have a 3S in one of my planes which has ove 360 flights on it and it has really be abused. Super fat 6-10 min. charges, over charged to between 3.8 and 4.1 volts per cell and it also still delivers 2100 + .
