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.

Accessing the Debug Pins

Accessing the Battery

Start by removing the 18 Security Torx T-15 screws on the bottom.

The locations of the 18 screws.

Using an M4 Allen/Hex wrench or bit, remove the two screws holding the ESC in place.

The ESC after being removed.

Carefully unplug each of the connectors.

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