Hi,
I got a new electric motorcycle from China and was looking to do some programming of the controller, but unfortunately I can't find any info about it (and forget the seller, knows nothing of course).
Google translates the label in many ways, strangest is 'Nanjing Yuan takes the Tongshui Special Lemon road'.
I found the product here, but no guide: https://m.yoycart.com/Product/630270251966/
I searched the logo on tineye.com but nothing.
It's clear that it's max 110A and 72V, but does anyone out there know anything about it??
Thanks for any help!

It is 南京 far driver controller，you need a USB to ttl converter，i have a upper computer software,But I can't confirm whether the version can be connected
 
Yes, that's it, thanks Kaudio! :D The same product and name is shown on one video - https://www.youtube.com/watch?v=MPCjKuY65fI
Unfortunately no idea what he's talking about or where he ordered it from. I couldn't find the product on Alibaba or Aliexpress.

May I ask for a bit more help...

Any ideas where to get a manual and control software?
The USB-TTL is easy to find eg https://dratek.cz/arduino/947-usb-ttl-prevodnik.html. Do you think this will work?

Cheers!
 
Sorry I remembered wrong，It is USB to RS232 converter，The file is in the attachment，The document is written in Chinese, you need to translate it。

It may be the lack of Chinese fonts, you can try to change to English from the above settings.
 
according to similar naming rule like Votol 72330, max current shall be something around like:
Rated current: 100A
Boost current: 130A
Peak current: 330A
