As everydayflyer and the instruction manual indicated the cell voltages are gradually being equalized during the blinking. With a 3S you would only have one or two of the cell lights blinking during the balancing of the cell voltages.

Instruction manual ... “5. The corresponding green LED of unbalanced battery (C1..C6) will blink during charging. The charger is discharging[one or more of] the batteries[cells] to balance the[ir] voltage[s].”

The confusion here is in not knowing how long the blinking will continue which is due in large part to the lack of not knowing/seeing each cell’s readout voltage before, during and at full charge.

At the very least invest $15 in an E-flite Li-Po Cell Voltage Checker EFLA111 to get some idea before charging of the disparity between the three cells. Then with more experience you’ll get a pretty good idea how long you can expect the green light(s) to keep blinking until the voltages of the three cells are within reasonable proximity. You’ll also gain an understanding of whether or not one of the cells is so out-of-balance that it may be useless to try balancing and time to get a replacement Li-Po.

EDIT ... The voltage readouts may be off by say 0.05-0.20 volts with any of these cell checkers (CSRC,E-flite,dealextreme) but you really only need an approximate readout not scientific notation. Even though the voltage readouts are slightly off the voltage readout difference/disparity between each cell should/will be accurate.
