Thank you both for your reply, i agree there should be something in the software to limit the over voltage scenario when the brake is applied at high speed but there doesn’t appear to be. I was going down a hill and hit the brake and it didn’t try to let up on the brake even a little before it...

A fuse on the wires running to the motor? Interesting idea - I guess we’d have to figure out what the current draw and voltage is under normal operating conditions and then install the correct type of fuse. Ideally though there would be something to add to the board to handle this scenario...

After reading some info on the french forums I've gone ahead and purchased some upgraded MOSFETs and a MOSFET driver. Current MOSFETs: Clone Boards: (ST - 110N7F6 - 110A / 68v) ES4 Model: (NCE - NCEP85T14 140A / 85v) SNSC Model: (NCE - NCEP01T13A 130A / 100v) Current MOSFET Driver...

Hi All, Along with about 80% of the other riders, I've had the unfortunate experience of frying the controller on my Ninebot ES2/ES4. After researching online I came to the conclusion that these boards are flawed in their design and many consumers are having to replace their control boards...
