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 don’t want to over drain the battery

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

Let me break down what im looking for. the min volts per cell should not be below x.xxV and the total volts per cell should not be below xx.x. and you should be getting an avrage flite time of xxMin. im already monitoring the voltage but if i dont know the minumens that it does me know good.

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?

I have the same plane and I get 20 to 30 min flight times depending on weather(wind)
