Hi,
I am trying to make a usb charger. There are going to be two solar panels @3v 20mah in series, they will be trickle charging two 3v AAA batteries. What i am not sure about is how to stop the batterys from overcharging. I thought i could use zener. Help would be much appreciated, and possibly schematics. Any info extra infomation i have missed just say.
Thanks,
