Hey all. I'm confused. I know that if I hook 2 1F 2.5v caps in Parralle I get .5F at 5V. But if I hook 2 1F caps in series do I get 2F at 1.15V or 2F at...

... Nope. If you connect two 1F, 2.5V caps in parallel you will have a 2F, 2.5V cap. ... In series you would get 0.5F at 5V ... OK, you need 1F at 5V, so this...
