STLink Ninebot Max BMS
In the case of a bricked BMS/battery, STLinking can save the battery from needing to be replaced in some instances.
For this process you will need:
- Windows computer
- STLink (Decent quality clones will work)
- Tools to disassemble the scooter and access the ESC
- Dupont male/female jumper cables
This process can be dangerous if done incorrectly so take caution when performing these steps and make sure you use a computer you are comfortable possibly destroying.
If you short a battery line you could end up blowing up your STLink, Computer, and more or even causing a fire.

You may need to scrape more rubber potting compound away from some of the connectors in order to unplug them.
