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, to prevent a back flow of current from the battery into the [...]
The circuit is a good battery. It is Control Volttage regulator Output 12V 1.5A , Input Voltage battery 5V-13V Only. Use IC- MC34063 so easy circuit, Adjustable VR1 for Control Efficiency at 12V 600mA.

I use the circuit above to monitor the voltage level of my Li-Poly battery packs during flight. The two Super Bright LEDs light up when the voltage level of the pack gets below 10 volts. I currently use Li-Poly cell packs that have three cells in series and four or five cells in parallel (3S4P [...]
