It is not a LiHV battery and I discharged at 2 amps. I have also confirmed that the charger was discharging to 3.1 volts and charging to 4.2 volts. I might do another cycle just to double check the result. If I get 7000 to 7100 then that would ok with me. If I'm still getting around 6700 then maybe this battery was sitting on the shelf for a long time before it got shipped to me.

I also emailed Hobbyking about the lower battery capacity and this is the response I got.

"LiPo batteries follow the 80/20 rule. You should NEVER completely discharge a lipo. 80% of a 7500mAh lipo is 6000mAh so that is all you should ever take out and put back in."

Is there any truth to this?
