Flakk I want to build a solar charger out of the same circuit. But i wanted to upgrade on that too. I was building this http://www.solorb.com/elect/solarcirc/aacharge/index.html an AA charger. but i wanted a higher power charger for 12v and 2.16a (they peak at 15v) batteries.
J4D The circuit im using is not good for you at all, here is a gr8 circuit that does just what you want . practically its an overcharge protector . http://ghurd.info/index.html
