status LED will flash green which indicates the charger is ready to charge.
Select the battery type LiPo/LiFe by the toggle switch.
Select the proper charging current 1A/2A/3A by the toggle switch.
Connect the battery main charge lead to battery socket which is in the front side of the charger and
battery balance wire to balance port which is in the right side of the charger.
The charger starts charging. The charge status LED and the cell status LED will glow constant red. If

Cell 1, Cell 2 and Cell 3 LEDs will glow constant red; and so on.
During the charging progress, when the charge
status LED glows constant red, the charger is
charging in CC mode; when the charge status
LED glows constant orange, the charger is
charging in CV mode;
When the cell LED is flashing, this cell is
discharging for balancing.
When the battery is fully charged, the charge
