Is it silly to run the Q128C 328RPM 36V in a 26 inch wheel with an old 48V 11.6 ah bottle battery with the 20A sine wave controller.

Will the torque be so poor it wont be worth it. Would the 48V 328 be the better option?

If you have any experience running this it would be great to hear from you.

Many thanks,

Matt.

I'm pretty sure that the 48v 328 rpm and the 36v 201 rpm are exactly the same motor apart from the label.

The only thing that seems dodgy to me is using an old battery and a 20A controller. You might get a lot of voltage sag and not much range unless the battery is in good condition.

Hi,

Really the same motor? I'm currently running a 201rpm q128h and it's working fine, I thought the 328 might be quicker at top end.

Thanks for the reply as always.

Matt.

The 36v 201 rpm Q128H is 201 rpm.
The 36v 201 rpm Q128C is 260 rpm.

When you run a 36v 201 rpm motor at 48v, it becomes 260 rpm.
When you run a 26v 260 rpm motor at 48v, it becomes 328 rpm.

I have an Q128H 800 motor 36v 201 rpm but it is about 260rpm.But that is the newest Q128H 800w version from bms battery.Didnt that motor change the motor housing?

Don't forget that a 36v 201 rpm one will spin to 235 rpm at 42v, or does yours do 260 rpm at 36v, which was the original speed of all H versions.
