Hahahah and now you have a space monkey on a capacitor rocket :smiley:

I want to use supercap about 1F as backup power for microcontroller in power down mode(few uA). In active mode it will be connected to 3.3V source which uses 4S Lipo battery. How should I connect it to power source and to microcontroller?

I described in detail how to do it in a prior posting in this thread.
