Update on Lithium poly testing

This is how I read it.

Look at the KoKam 2000 (2AH) plot.

At a constant 15A draw, it provides 7.5 min of operation.

mah/15000ma = 7.5min/60

x = 1875mah

Another thought, what is the temp at the time you are trying to fly? Cold temperatures, <50F, cause NiMH batteries to lose a lot of power. Enough at 40F to cause flying problems. If these are...
