Mar 23, 2022 · I have some 2.7 V, 500 F supercapacitors and I would like to quickly charge them from two 18650 VTC6s in parallel. I made this simple circuit and I would like to make sure it works before I …

May 14, 2024 · Is this discharge normal? Is it possible that the capacitor is low-quality with high leakage? Do I understand this topic correctly? Did I miss any important info about super-capacitors? …

Suppose I have a device that utilizes a supercapacitor. How long will it take to wear out the supercapacitor so that it needs replacement?

May 13, 2024 · Of course if you have more capacitance/lower ESR than your circuit needs to operate your circuit will have longer life since the end-of-life (due to wear-out) point is arbitrary. The opposite …

What's the formula to calculate how many seconds a supercapacitor can provide power when employing a buck/boost converter? Also, how different would that calculation be when using a pair of superc...

Mar 28, 2023 · I am building a hobby project - a sort of supercapacitor powerbank, where I basically connected twelve 500F 2.7V supercapacitors in series. Despite these capacitors being from same …

Jul 29, 2019 · The circuit is based around existing supercapacitor protection modules and uses a TL431 (actually a TLV431 lower power version) precision Zener device. Basically, the circuit works, but I …

Nov 11, 2014 · I am working on adding a super-capacitor to one of my 5V lines. Foolishly I tried adding the super-capacitor directly to the 5V line, but it over stresses my regulator to charge it all at once. ...

Apr 8, 2021 · I was thinking of purchasing a supercapacitor bank and connecting it in parallel to the converter's output. My understanding is that the converter will slowly charge up the caps initially, and …

Nov 12, 2023 · Why the super-capacitor if you want to modify the electronics to ignore the absence of a battery to begin with?
