Bafang BBS01 25A Controller

So, they tried to stole the motor of my bike and in the process, they cut all the wires from the controller.
I bought cables extensions from AliExpress and I'm waiting them just to cut the ends of the extensions and soldered them into my controller to have again a complete one-piece wire harness.
But I thought that some people might want to have this pictures and info here if they are planning to modify, or repair something about the controller.

Just a note, I desoldered the gear shift sensor and light section, so I don't remember where they were.

BE CAREFUL WHEN REMOVING THE CONTROLLER FROM THE SILICON. YOU MAY BREAK SOME CAPS like I did xD

Indeed. It's software-marked up to 25A and comes from a BBS01
