Good day, all
I want to add capacitors to the Raspberry Pi power-supply.
Currently I have my raspberry Pi plugged straight into a portable 5v battery, this works fine. However, I want to be able to swap from one battery to another battery (via a switch) without the Raspberry Pi turning off. I figured the easiest way to do this is with supercapacitors (after I do some researches and get the ideas from Electronic Supercapacitor Applications Guide.
I've added two 25F 2.5v supercapacitors in series as shown in the picture. However, when I do this, the raspberry pi powers on for about 10 seconds (both red and green lights come on) but then it shuts down.
Is there anyone have ideas of it? Many thanks.
