Ah, I see that chart now. Wow, at the 'maximize,' 50 watt setting of the 801, the overall efficiency is only about 15%. No way I'm going to get real long distance running at the lower wattage rates...
Thanks,

Smaller motors are more efficient at lower power inputs because of this characteristic. You want to choose a motor that is operating in the middle of the input power curve with your average load not your peak load. Otherwise you run your batteries down to quickly. Thanks. Steve S.
