Thanks for the reply, Amberwolf!

Then it is just a normal PWM motor controller like almost everything uses nowadays.
But you understand that it sounds very impressive to a layman like me, especially as I previously had a no-name brand motor that ate batteries for breakfast:)
Currently I have an el-cheapo 40AH LifePo4 battery from a previous motor, but I want to upgrade as this motor supposedly uses up to 42 amps per hour at full throttle, which doesn't give much running time.
I think you mean 42Ah per hour.
Eh? More reading to do apparently. The Minn Kota website says it has a maximum amp draw of 42 amps. OIC, ok I read and I think I understand.
Any watt meter should measure the total Ah and Wh thru it regardless of how you put it thru it, in pulses or continuous, as long as it has a memory that stores teh info if the pulses are at the battery side and go below it's minimum threshold.
If the pulses are at the controller/motor, then it makes absolutely no difference to the wattmeter, as it only sees battery current/voltage.
Thanks, that's encouraging. I asked the same of the Watt's up manufacturer yesterday and their techie had a similar answer, although he was a bit more elusive in his answer.
I'll give it a go as soon as the weather clears up around here.
