Assume you got the manual, so do a little reading. You set 3.7v in "user set program" for teh volts per cell. Then you start by going to program select and selecting li-po. This is page 9. If you want to balance you need to go to "lipo balance". Once yoiu get info entered, just press enter to start the charge.

I don't have this charger, but its similar to my Accucel-6 and GT Power A610 chargers.
