    Water got on the board, the board only 36 volts from the battery, no other voltages, diodes and transistors are intact.

        I understand this is a chip from China that no one knows about, maybe someone had problems with this controller?

              The board is some Chinese copy.

              That chip is some 12V regulator.

                I ordered exactly the same controller on AliExpress, replaced the motor control chip, everything works.
