Hi, after some Brainstorming und thinking, I unlocked the battery very easily (simple), but if you want to try this "mod" you have to extract battery pack out of aluminium housing, to get access to the BMS.
Don't try to push the battery pack out of the Aluminium case. You will only damage the electronics inside!
The easiest way is to to cut aluminium case with a flexxcutter (Winkelschleifer).
One long cut at the opposite side of the BMS...
The naked battery pack must be cleaned of the pottery. At the BMS there are some MOSFETs.
Between them ist im freespace for another MOSFET but this spot is empty.
You have to to make a connection between the the spot of the empty MOSFETplace and a little contact point sonme millimeters up.
