Default Cheetah U3520-6 motor

I'm trying to find the power specs for this motor, i.e., number of battery cells and amps or watts. I know the kV is 840. It was originally sold by BP Hobbies who stated that Cheetah motors are made by Suppo. The motor is not listed on the Suppo website.

Thanks,

Gordone

Any voltage, as long as current and rpm don't get too high. Wire insulationlacquer can handle several hunderd volt.
