I should have thought of that, I was concerned that with LED I was driving, I wouldn't have the extra volt or 2 needed to use the LM317. I was right to a point. It doesn't really regulate until I get over 15+ volts and my buggy generates 14.4 volts. The LED likes 12.6 and 800ma for the 10W rating, I have been wanting to make a voltage boost to power a laptop and if I can do that, I can also use the same design for the extra volts for my LED to be properly regulated. What I'm trying right now, & it's not working very well, is a 1 Ohm resistor and a .9 ohm thermistor in series, but I get too much current until every thing warms up, could try a higher resistance thermistor, but it still won't be as stable as the LM317 with a 1.5 ohm, 3W, 1% resistor.
Still hoping someone will chime in with a boost circuit that can give me that little extra voltage.
