how to make lithium charger - lithium ion polymer battery

You need this item when you have additional mobile batteries or you need to charge any lithium, lithium or lithium polymer batteries.
The maximum current is about 650 mA.
The circuit is designed for batteries of 900 mah or higher.
The power supply can be a 12 v Gell battery (Power panel)
Or it can be driven with the cigarette lighter of the car.
I used the old 12 v DC wall transformer (800ma or more. )
The circuit is simple and you need the following LM317 variable regulator 2n222222a or any transistor handle 800mA2 capacitor 0.

Adjusting R4 to the desired output voltage 1 to control the PCB of the output current item, I used the "toner transfer" method, which is very powerful and simple.
Using HP Glossy paper and laser printer after welding the Assembly, a complete project with good results is given. In the case of charging the larger battery, I used one for the LM317
