I remembered I once asked a seller on AliExpress, what is the difference in ES4 version 1.3?
The reply:
for the new version V1.3 Black Color
i think you have heard about that the gray color version has lot of problems.
the news version has changed or updated
1. the Controller: when you open headlight, the speed will drop very fast, this is the problem for gray color, now, the black version has solved this problem.
they have put a new software in Controller.
2. the Rear Wheel Fender.
In Youtube, many customer make video that their Ninebot ES2 gray color broken in this parts, very easy broken in this parts.
the new version has changed or updated the material of the rear fender.
it will not broken easily.
I am not sure how accurate the reply is, but I think it's relevant to your issue about the headlight.
