I'm in the same shoes: since I upgraded from ES2 to ES4 with the extra battery, it developed two issues:
- max speed is lower when I turn on the light
- sometimes it switches off accidentally during braking. This one is quite dangerous, as during braking the scooter switches off, I loose braking power, and the scooter got into gliding mode. Frightening.

Any thread to replace the board?
