Default Battery Qustion on flight time and max drain

What is the max I should let the 3200 11.1V 20C 3S Lipo be drown down to and how much flight time should i be getting. I have an Apprentice S e15. And I have my battery beeper from my Belt-CP on it I have been getting about 20Min flight times and have not gotten the beeper to go off or blink. I donít want to over drain the battery

You should be monitoring the voltage after each flight with a meter.

About 3.4v under load is a good LVC level. You should not drain more than ~80% of your packs capacity, so it is a good idea to time a few typical flights to LVC, and then see how much you are putting back in when recharging. That will tell you whether 3.4v is safe enough.

ok, so when i check my battery i should have about 3.5V in each cell. for a tottal of 10.5V left in hte battery. if so then my 20 min flights are about right. if i only do a 10Min flight and leave about 11.5V or so that wou'nt hurt it?
