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
Vbat: Battery voltage
Iset: Discharge current
For example: discharge a pack of 20V lithium battery at 7A
R = 20V / 7A = 2.85Ω
P = 20V X 7A = 140W
