3rd and 4th cycles... you really aren't getting any new info. The only reason to do 2 is a pack that's sat a while may REALLY bounce back the second go round. 3rd should be really close to 2nd. (maybe a little gain or loss... they never seem to read the same twice in a row.)

Its in the acceptable range (assuming they are 600 rated) Just use the ESV between flights (at the end of each flight) and if its dropped below 4.9... recharge before the next takeoff. You shouldn't go in from lack of battery power.

(plenty of other ways to wreck one... I think I found em all.[&:])
