I haven't recharged the packs as that was the last flight on them for the day. They measured 3.74 +/- .01v per cell across all 12 cells.
As soon as I have time, I'll run a charge then a storage and let you know.
What I can say, is that he wasn't shy on the throttle, and we still got a 6 minute flight on the packs 2x 5300 packs... that's kind of unheard of, isn't it?
If you are still at 3.74v per cell, that’s great. It also means that he had no need to really push the plane.
5300mAh will probably use about 70% capacity if they still come down at 3.74v per cell. That would mean you will put back 3700mAh when recharging.
If this turns out to be the case and the motor at WOT draws 125A, then he wasn’t on the throttle much at all. Here’s why….
A six minute flight is a 10C discharge rate.
If the motor is peaking at 125A at WOT, then he must be average only 30% of the power average, which ranges from zero Amps to 125A at WOT. Unless there is a throttle curved programmed into the Tx, that could easily be considered a 30% throttle average.
30% of 125A is a 37.5A average.
37.5A divided by 3.71 Amp Hours is 10C.
60 minutes divided by 10C is 6 minutes.
If you’re getting an average of 3.65v per cell, throughout the flight, which is normal, and you are peaking out at 125A, then you are peaking at 5475W.
If he was using 40% throttle (power average), and getting 6 minutes, and using 3700mAh, then the peak was only 106A, which means a peak of 4710W. Either way, he was only using an average of about 1650W over the entire flight.
