oh, I see why you didn't understand. you didn't know that watts = hp. such a
pity.

Also you seem unable to comprehend that ~750 watts put into a battery bank for
one hour gives back ~hp per hour, less inefficiencies.

don't worry, just go with the flow.

oh, you mean horsepower can not be compared to watts?

Gee, the European engine manufacturers do it all the time. somebody should
tell them you can't do that.

No, I mean this:

"6 amps at 12 volts for 24 hours = 1,728 watts, which = 2.3 hp-hours."

Amps times Volts times hours = Watt-hrs, a unit of energy
Horspower times hours= hp-hrs, a unit of energy
Watts are units of power
Horsepower is a unit of power (who would of thought it?)

Energy and power are two different things, which you well know.
