I bought another Maisone 16000 mAh 22.2v battery so was comparing the two in flight times yesterday.  
One lasted just 4 minutes before the red-blinking 2nd-warning level light came on and I landed, and tested (after a suitable 20 minute rest) at "54%".  

The other lasted 12 minutes of flight time, same activity (but with a lighter payload), before the red-blinking 2nd-warning level light came on and I landed, and tested (after a suitable 20 minute rest) at "2%".


"2%" ! I almost had a coronary.  

I understand it is not good to take the capacity much below 50%, but have no idea why the second battery did not exhaust the voltage sooner, and why the capacity was able to creep so low.  

There were no changes in the configuration on the A3:  1st warning level is 22v, second level is 21v.  

Ideas and guesses welcome.

Thanks,

-Peter
