Hi ![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I bought a button with a LED diode inside. Working voltage of the diode is 9-24V DC.
I want to use it to switch on the bms module in my e-bike battery. I will power the LED diode directly from it. The voltage of a fully charged battery is 54.6V, and of a discharged - 36V. What resistor should I use to power the diode when the voltage will decrease with the discharge of the battery?
