Super Capacitor 2.7V 500F X 6 module

Recommended Posts

I have this 2.7V 500F super capacitor bank but it seems to me that there are two pins on each capacitor that are there ready to be soldered but were not. I have seen videos of the same capacitor bank from green-cap and it seems to me that the ones I see on youtube have these pins soldered. I wonder if anyone could shed some light on this for me. I have tested the voltage and raised it some and lowered it some and it seems to work so I am wondering what is going on with these pins.

Thank you kindly

It seems that your cap has 4 pins on the bottom, two of them are the actual capacitor terminals and the other two are for mechanical stability and not play any electric role. Check the attachment. You can also notice that there are no tracks going to these pins, so it's OK not to be soldered.
