I am not much experienced with electronics. But I am aware that supercapacitors must be charged with lower voltages than rated. I want to make a simple spot welder using this capacitor.
I have the following things. Can someone tell me what is needed (resistors/Schottky-diodes) and how to connect them?
- 100F 2.7V super capacitor
- 5V 1.0A mobile charger, non branded
- multimeter for measurements
I want to charge the capacitor at 2V and then short it over nickel strip to weld the strip to 18650 battery terminal.
