I have now run into an issue on some new mother boards (Intel Atom) where I can...
I am investigating using ultracapacitors as a substitute for a SLA battery for a UPS application. I came across a few manufacturers of ultracapaitors with values of 3000F for a single large cell cap but have low (2.7V) operating ratings.
I would like to place the caps in series to increase the...
