RE: [Electric Boats] FW: New Member from Iceland--- a Note or two

 

Indeed but I thought it was obvious what kW and kWh is. I suppose I just think in Wh consumed from the battery at a given cruising speed in knots. And I think of power being that measured at the motor in Watts (at a known efficiency based on rpm and load) taken from Volts/Amps readings at the motor. Differences between battery and motor being the losses via wiring/controller so I get an idea of system efficiency.
