My batteries for the Q500 4k are only about 3 months old. They charge up well with the Yuneec charger. After installation in the copter I read 12.5 volts and 4 green bars. After starting the motors and taking off I notice that the indicated voltage drops to 12V about 1 minute into flight. Then in the next minute it goes to 11.8. With the camera running for about 5 minutes and easy use of the copter I got 16 minutes when the 10.7 Yellow appeared and landed. If I had been more aggressive with the copter I am sure the flight time would have been less. Does this sound about normal for these batteries?
