Important Notes
The Charging Principle for Reflex Charge Mode
Power Regenerative Mode
Lithium Battery Extra Discharge Mode
You can expand the iCharger’s discharge power capacity by connecting the external capacity resistance. You should pay
special attention when expanding the discharge circuit. The balance port must be connected to the battery and the
expanding capacity resistance R should be connected in series to the positive connection. (See the following diagram)
In this mode, the lithium battery discharges through the iCharger and R, P = Pi + Pr, (Pi is the charger’s wasted power
capacity; Pr is wasted power capacity by resistance). Pi is limited by the set charger’s maximum discharge power
capacity.
External capacity resistance’s setting:
R = Vbat / Iset;
P = Vbat * Iset;
R: The value of the external capacity resistance
P: Rating capacity of the external capacity resistance
Iset: Discharge current
Vbat: Battery voltage
For example: discharge a pack of 20V lithium battery at 7A
R = 20V / 7A = 2.85Ω
P = 20V X 7A = 140W

Note: Reflex charge mode only supports NiMH and
Pb battery. It does not support lithium battery.
Using reflex charge mode to charge battery can
reduce effectively the heating of the battery. Go to the
MEMORY SETUP → Charge → Chg Mode to select
Reflex mode.
Note: Power Regenerative Mode: which is when the
power supply for the charger acts as "battery power",
the charger will regenerative charge for "battery
power" during the process to discharge the battery.
Go to MEMORYSETUP → Discharge → Regenerative
-Mode to select To input mode.
