Re: ES4 still won't go above 24kph after BMS & DRV updates.

I downloaded the Ninebot-Flasher for Windows from the toolbox thread, and when connected it had the ability to upload the BMS file for each battery. I hope that helps. Let me know if you figure out the reduced speed issue as I mentioned. Where did you have the possibility to upload and flash the BM...

Re: ES2L can't go above 26 km/h

I have a similar issue and posted a separate thread on this, but for the record my scooter is a factory ES4 ,so I don't understand why it would be limited all of the sudden by the serial number. If someone can explain that I would appreciate it. Also eager to hear if others changing their serial num...

Re: ES4 still won't go above 24kph after BMS & DRV updates.

Quick update...I checked the terminals and no corrosion so I am back to square one. Any other suggestions? Thank you in advance. Sorry for being off topic, but how do you update your BMS on both batteries? I did a custom firmware flash, but BMS remains. Thank you and good luck. I am having similar ...

Re: ES4 still won't go above 24kph after BMS & DRV updates.

Thanks for the inputs. I have adjusted my post to reflect metric instead of standard. I will check the connections tonight although I must admit that the batteries both show up and both drain equally when riding. As well, I still have the ability to climb steeper hills that I wasn't able to with the...

ES4 still won't go above 24kph after BMS & DRV updates.

Looking for some guidance on next steps to get my scooter back up to higher speeds. I used to be able to go 29-30kph in the bike lanes, but about 3 weeks ago it suddenly cut to 24kph. I have made sure it is getting a full charge, and both batteries look good based on the Ninebot app info. I figured ...
