Ninebot by Segway - ES1, ES2, ES3, ES4 - Compatible Replacement Mainboard Controller Part
Please note this is a compatible controller and activation is not needed. It has been tested this on ES2 model and it works well. Key differences from the original unit: While it can handle second battery (ES4 battery pack upgrade) - we do not recommend this as it may damage the controller.
If you wish to use the ES4 battery pack or if this is to replace an ES4 controller, we recoemmend purchasing the genuine mainboard controller part which is for sale on our other listing.
