Lithium Ion, Lithium Poly Charger Circuit -  The above circuit will charge any 2-cell * Li-Ion battery pack. Maximum current is about 650 milliamps. The circuit is designed for batteries of 900mah or higher. Note this circuit is NOT for Li-Metal batts (i.e. Duralites). Power source can be a 12v Gell cell (Power panel), or can be powered by a car's cigarette lighter. I use an old 12v DC wall transformer (800ma or more.) Radio shack sells a 12v/1amp wall DC adapter #273-1776 that will work. Supply does not need to be regulated. In fact my cheap supply outputs 17 volts with no load. ….(Circuit design added 11/08)
Lithium-Ion Charger, Single cell -  The LP2951 regulator is manufactured by National Semiconductors. The choice of values is from an application note "Battery Charging", written by Chester Simpson.  Diode D1 can be any diode from the 1N00x series, whichever is conveniently available. It functions as a blocking diode, …. [Tony van Roon's circuit]
