OK if you look at the first log you can see the overall headspeed, amps and RPM figures.
The pack was given an average 24A load, so just about 11C, which is exactly the type of average load you want to give some longevity.
At the beginning of the flight unloaded RPM is around about 2950, by half way it was 2890 and towards the end 2800. So across the flight with voltage depression we lost 150RPM total.
Pack voltage averaged 10.66 which is 3.55V per cell. That's very good, the good packs on the market are doing about 3.6v per cell average max, so it's up there.
Mid flight I did some nice big peak amp draws of 40+ amps, voltage dopped on these to 10.22 which is 3.4V. So nice and safe, no danger of voltage cut off.
End of flight the pack was warm but not hot.
So indications are that it's a pretty good pack from voltage perspective. We need people to run them now and determine cycle life. I will check voltage hold every 10 flights or so and keep an eye on capacity losses. Powerwise, no issues, just cycle life to look at now.
