Hi Guys,
I bought a used scooter today, and it comes with a "unknown" motor controller and a LCD display. The label on the controller is washed out and there is no label on any of the wires, so I am quite at lost on what it is and its specs.
It is quite small and light, with a dimension of 88x52x30mm (not measuring the screw heads). I took one side cover off and found it has 6 MOSFETs, and the outer most one read RU6888r (I assume the other 5 are the same), and the big capacitor (blue in the center in the pic) is rated 63V 680uf, and I can read one more smaller cap rated at 100V (the brown one on the right in the pic).
The LCD comes with it is CD-S886, with a throttle thumb switch.
The previous owner also cut/resolderred/modified some of the plugs/wires to fit the scooter, this includes the power wires, the motor phase wires, and the motor hall sensor wires.
I think I can recognize most if not all the plugs, I am not sure about the PAS and the throttle plug, as the LCD has a throttle switch. The LCD itself has a 5 wire plug.
I would like to know if this is rated at 36V or 48V? Can I assume it is only 250W? The battery that comes with the controller is 12s (at only 12 cells, so probably only 4Ah?), I guess it is 43.2V already, but not quite 48V.
Thanks!
