I put ~40V thru a 24V 450W motor

I also did some testing "straight" off of the battery pack

* "Personal Analysis, of the (3) tests with the ZY1020 48V 1,000W motor

Alfa Wheels speed controller
Take-off ~25A
Accelerating ~25A
Constant/crusin' ~12A
Top speed ~14 MPH

TD Pro speed controller
Take-off ~30A
Accelerating ~30A
Constant/crisin ~10A
Top speed ~14 MPH

With-out a speed controller (just a battery pack, beefy switch & motor)

Take-off (up to) ~100A
Accelerating ~50A
Constant/crusin ~10A - 12A
Top speed ~14 MPH

So, (as Sid said) the speed controller (available amps) doesn't seem to be holding the motor back

The only advantage, I see, is a "harder" acceleration
...but, at the expense of "lots" of amps
…& the top speed was still ~14MPH either way"
