< SOLVED! Problem was actually just that LCD3 was not connected to S12S controller, when connector is jumpered to get things moving the controller output is limited. S12S controller must be used with LCD3!>
Hi folks,
I've just completed the build of my first bike, and sadly i didn't hit my own specs so need some help.
My target is:
Stealth look at top speed around 45 km/h / 28 mph with me pedalling full blast as assist to motor.
I want it to be a bike, will always be pedalling, and am fairly fit. I can output 30km/h / 19mph / 150w average on my own. My commuter ride is flat and this will be 99% of my riding on the bike.
I have this kit now from BMSbattery.com:
Q100 328 motor 36V
S12s controller, max amps: 23
48V 9Ah LiFePO4 battery, max current output 15A (limited by BMS)
During my first testride my max speed was 37 km/h without pedalling which was expected but what was not expected was that when pedalling i managed only to increase speed to 39 km/h! It seemed that the motor lowered the assist when pedalling so net effect was minimal. I need a longer ride to check more but from the ebike simulator the motor should not be at its kV limit at this speed so what's going on?
What is the good way to get my spec fulfilled? My first idea is overvolting to 60V, maybe this works in my usage even with the Q100 small size and nominal effect.
Will the S12S controller be able to take higher Voltage than the speced 48V?
