kelly kls7212n suitable motor

suggest Best suitable motor and max power for kelly kls7212n controller :wink:

It can feed 160A for 90 seconds, 60A continuous. Yet it is rated 1800w continuous, which does correspond to its maximum continuous Amps at its minimum voltage of 30v (30 X 60 : 1800). Since its maximum voltage tolerance is 90v, the theorical maximum power attainable should be 14400w, if the software does let you set the max Amps at max voltage. Yet it could only feed that much for a few seconds before overheating, but this controller has a temp safety function that would prevent overheating by limiting the power.

You should normally stick to the 1800w continuous figure, thus the best ‘performance’ motor for it should be able to be fed 1800w continuous. BUT, there are other factors of selection for a motor, that concern the bike’s purpose and rider’s preferences. A programmable controller is meant to be set to match the battery/motor combo, not the other way around.

Not sure how this factors into the calcs, but per Kelly's FAQ, their ratings are motor current, not battery input current (which makes them hard to compare with other controllers ratings).

Yep. That is why I said ‘It can feed’.
You can presume that it does pull about half the output Amps from the battery, which would compare with a 80A controller that is spec for battery current.

What's your donor bike. What kind of battery room do you have ? Where you going to put the controller ? The Battery is the heart of any ebike.
A mxus 3,000 is a start.
