Thanks,

Can I use a welding pen with a 2.7v 500f super capacitor? Of course I will connect it in series to make 2 super capacitors

Sure you can. but better to read this post about any upgrades. This post is about your interest. ua-cam.com/channels/j6sPESaMxC6O4u7Xb0Gibw.htmlcommunity

@HobbyElectroLab thanks bro

[@sumdumhick]

How many volts do you apply to the capacitors?

[@HobbyElectroLab]

25v dc

[@wahyupriadi95]

what voltage rating do you use?

[@HobbyElectroLab]

I used 12V DC but 24V can also be applied. make sure to match the capacitor's working voltage.

I want to ask, I have a 500f super capacitor with a voltage of 2.7 volts. Do you think I should combine it in series to 5 volts or in parallel?
