***Do not mess about trying to design a Lithium battery charger using inappropriate parts.*** You **will** come to harm if you do that! Read: https://en.wikipedia.org/wiki/Lithium_polymer_battery especially the section on `Safety`. Then go to: http://batteryuniversity.com/learn/ Read especially: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries then go to: http://www.microchip.com/search/searchapp/searchhome.aspx?q=Lithium-Polymer%20battery%20charger&resperpage=10&id=2 Find a(some) suitable device(s) and **read the datasheets and apps notes very carefully**.

@andyfierman thank you so much but i have not got any mcp**** or max****

So you probably cannot make a safe LiPo battery charger.

@andyfierman thank you again. Ok, me cannot make charger because i have not got parts for it

If you read and understand the information I pointed you to and then choose a part from Microsemi or some other manufacturer and then bud a design following their apps notes, you should be OK. You may be able to get the parts through EasyEDA. Do your design, create the BoM and then​ ask Support if EasyEDA can supply the parts or even a PCBA. :)

thank you. so now my 2nd lipo battery gets up (it again works). your answers help me to find a good charger for me. THANK YOU SO MUCH :D. you realy help me!
