The lipo charge profile is called constant charge / constant voltage (cc/cv)

The intial charge is whatever amp rate you set until voltage reaches 4.2v per cell. The the voltage is held at 4.2v per cell and the amp rate falls until it hits 0. The battery is then fully charged. Usually about 10% of the capacity is put in during the CV mode. The other 90% goes in during the CC mode.
