I also bought the ninebot es2lte. I had to replace the dashboard because of a defect. I ordered the dashboard and installed it and it runs without any problems.but the new dashboard that I installed is still throttled and now runs 25kmh.I got the external battery and the performance is significantly higher with the battery.PS to all those who want to replace the dashboard of the ninebot es2 itself, please do so only if you have experience with repairs. The repair is not exactly easy and you need experience in this area.
