The SR controls are the newest generation. They do things we wish our old controller did like reverse polarity protection on both input and output sides,
So you are protected from any mishap or install error
Many other features are new like built in cooling fan and automatic throttle signal calibration. Increased peak and sustained outputs make the 500 equal to the old 600 controls.... More program options like build your own throttle and torque curves. And simple USB compatible programming......
Built in cooling fan extends peak performance by reducing heat
and each controller carries a full 2 year warranty.

What does the Speed Control do?
The Speed Control regulates the amperage flow
from the battery pack to the motor.
What is the solenoid?
The Solenoid is the on/off switch between speed controller
and the battery pack.
Bigger tires, more passengers, soft footing or hills
all require more power & increased amperage flow.
