The rated voltage of the Tianjin Santroll WZKD3615KA-BTN-Z2 controller is 36 volts.
Is there anyone that has opened this controller and/or tried to overvolt this controller?
What do you expect from the components used, to be the maximum voltage? Or what was the maximum voltage you applied without damaging the controller?
Note: in winter/cold season (< 10ºC outdoors)
