They don't seem eager to reveal actual power or energy consumption. I
wonder why? The claim 300 amps peak, 170 amps continuous, and 30-50 amps
at "cruise speed". All meaningless because they also give a wide range
of operating voltages and don't say at what voltage all the other
ratings are measured.

yes, yes and yes...but it does look like a promising technology and one
that I'm actively considering...unless I have to stick a metric ton of
batteries under the cabin sole

To draw down a steady 50 amps for any length of time you need a
battery bank of approximately 1,000 amp hours. To do that with 12
volts would generate less than 1 horsepower, so I'm guessing 48 volts
minimum. That's about 40 golf cart batteries at 60 pounds each plus a
whole lot of interconnects. That works out to over 2,400 lbs (1,100
kg), at a cost of over $2,500 USD.
