I hope you can read this paragraph carefully so that you can avoid many problems when purchasing.
1. Please make sure that your original controller is the controller(communication protocol) before your device.
The KT controller is only suitable for KT series accessories, such as KT display, KT throttle, etc. If you encounter problems during installation, please contact us and we will try our best to help you solve it.
2. Please contact me if you are not sure which is right for you or have further questions.
A. The current of the controller is subject to the maximum current. Please do not use the rated current as the current of the controller. Otherwise, other parts of the electric bicycle will be overloaded.
B. A Light / Lamp for our KT controller must be about 70 mA ( less than 100 mA )or the controller will be damaged. I suggest you do not use the front and rear lights at the same time.
The difference between square wave controller and sine wave controller
-The sine wave controller has less noise and is more stable when riding, but it means more expensive.
-The square wave controller is more affordable and cheaper, which can meet daily cycling needs.
-But they have a consistent appearance
-The plugs of the square wave controller are the same as the sine wave controller, and the appearance is the same, only the nameplate is different.
