USB LiIon/LiPoly charger

by desidanger on Sat Sep 25, 2010 2:00 am

Hi,

I've few questions regarding this, first can i charge 5V battery with this Adafruit's(circuit)
http://www.adafruit.com/index.php?main_ ... cts_id=259
and secondly I want to add a 9V battery back up to it so just in case when there is no sun or Li-Po runs out of charge and you should be able to charge your cell phone by 9V battery (automatic switch)? I've ordered parts im going to build my own if anyone can help how i can integrate 9V back up to this circuit that will be great.

Thanks
desidanger
