Ninebot ES4 - Error code 46 (almost) solved


Recommended Posts


This message to let you know that I had the error code 46 on an ES4 ninebot segway.

I did a reset of the scooter (brake + speed + power 10s to get error code 10, then 14) then the battery was gone from the Segway app...

After crawling telegram I saw a picture with the batery opened and a circuit that needed soldering.

The external battery is hard to open, but I did it, then made back the connection, and the battery is back to live :)

Unfortunately, even if the battery is charging now without being attached to the ES2, when it's pluged, it seems it does not take power, neither transmitting it to the main battery.

I guess my controller might be broken, but I don't know how to test, and where to test this...

Anyone can help ?

Here's the picture I did and the (very bad) soldering I've done.

Hope this helps a bit :)
