SKYRC e4 Charger is an economic, high quality 100-240V AC balance charger, designed for charging LiPo and LiFe batteries from 2-4 cells in balance mode. The circuit power is 20W and max charge current can reach to 3A. There are three kinds of charge current 1A/2A/3A that can be selected. You could select the proper charge current according to the battery capacity.
There is one LED indicating the charge status (ready to charge/charge in CC mode/charge in CV/ mode/charge finish) and four LEDs indicating each battery cell status (charge/discharge). In this case, we could know the charge process at any time easily through the LEDs status.
