BMC motorParts collection

LocationNew Port Richey, Florida US map
Vehicle2008 Schwinn S60 DSX
MotorPower Pack Motors BMC 600w Brushless DC
This motor normally has a built in controller, which is now removed, and has wires for an external controller in place.

This removes a large source of heat from inside the case, and allows for much greater power.

Eventually I will do forced air cooling for the motor.
DrivetrainChain drive through the bottom bracket.
ControllerShenzen 48v 28a BLDC
Chinese made controller, works well for me for now.

I will be getting a Infinion controller in the next couple weeks
Batteries6 Milwaukee v28 Li-on, 28.00 Volt, Lithium-Ion
I have 6 Milwaukee v28 3AH Li-on batteries hooked up in 6p.

They are able to put out 15-20 amps each (with the BMS intact), so that gives me up to 90-120 amps at 28v. I will be changing them to 2s3p with my new controller.
System Voltage28 Volts
ChargerMilwaukee 3 Bay
1 Hour full charge for 3 batteries (2 hours for all 6).

Top Speed24 MPH (38 KPH)
At the moment, un-assisted top speed is about 24 mph. With new controller I am hoping for 35+
