So thats 350 amps avg in 3 minutes.
If you figure a good 3.5 turn is what 750-800 watts?
Divide that by the low voltage of 1s and taking into account the immense heat and loss of efficiency, its possible to see an avg. amp draw approaching 350.
Oval is constant throttle more or less isn't it?
We did some test with a 3.5T measuring current draw. We found the peak current draw was about 220A.
140A constant over 3 minutes is impressive for the Lipo they certainly get warm with 50A constant load.
What size wire and connections are they using? I am amazed wires and connections don't melt.
