But it is worth mentioning that the SNSC battery uses a different pad in contrast to the G30. And for use in the G30, I soldered to the P11 connector. Although unchanged, the P14 connector on the BMS works with the G30 controller
I going to build my own batterypacks from 18650 batteries that I have salvage from G30 batteries. So there I will completely rebuild the batteries with a new BMS, controller, and so on.

Then I think I will use the Okai ES400 batteries for a powerstation. With those I will keep the battery as it is and just change the BMS to another 13s BMS. Time will tell if I will get electrocuted or not...

This is a great discovery, unfortunately the execution is quite hard without the proper tool and I could not get it to open with my makeshift key. There is no guide for the key inside, so the dimension have to be exactly right.

I made a key that can be 3D printed, with it this should be easy.

  • 3D print SNSC2.3-Battery-Key-NoSupport.stl
    PLA with max top and bottom layers worked fine for me
  • remove the plastic cover and the metal bracket (the two screws are T25 5 star security torx, not the regular 6 star security torx!)
  • insert the key, put the scooter in the upright position, push the key all the way in and turn it 90 degree counterclockwise (CCW)
  • if the battery cover does not pop open, bump the top of the cover while holding the key in the 90 degree position
