Rm,

Unfortunately the way I have the data logger hooked up it’s only showing the voltage of one of the two battery packs, therefore the following number should be doubled (assuming consistency between packs).

At takeoff 60 amps drew the voltage down to 17.55v.

3.8 mins into the flight during a 4 second burst at 61.5 amps the voltage ranged between 17.1v to 16.86v.

6.8 mins into flight during a 2 second burst at 61 amps the voltage was 16.6v.
