I built this here using this person's design..
http://shdesigns.org/gcellchg.html
I get 13.5V on the output, but tiny loads like say a white LED has the voltage going from 13.5 to 2.8V and as soon as that load is released it goes back up to 13.5V again.
I don't have a 5k pot yet so I have a 100k in it's place now but still I have it set for a 13.5 V output and somehow my voltage output gets cut in half on the smallest possible loads.. my power supply is 17 V
