PWM pulse width modulation for kayak electric motor, 10-50V, 40A
Does your kayak electric motor only have 2 speeds? Do you want variable control on the throttle to go at any speed from 0 to 100 percent?
A PWM between your motor and battery will allow you to control the motor speed anywhere from zero to full throttle, giving you the perfect speed for trolling.
You will save battery by not travelling faster than your current motor control allows.
The cheapest worthy upgrade you can do.
