Lithium Battery External Expanding Discharge Mode - iCharger 106B+ User Manual

iCharger Synchronous Balance Charger/Discharger

Lithium battery external expanding discharge mode

You can expand the iCharger's discharge power capacity by connecting the external capacity resistance.
What should pay special attention is that, when expanding discharge,
battery and the expanding capacity resistance R should be series connected to the positive pole (See in the
following diagram)

In this mode, the lithium battery discharges through iCharger and R, P = Pi + Pr, (Pi is charger's wasted
power capacity; Pr is wasted power capacity by resistance). Pi is limited by the set charger's maximum
Series
discharge power capacity（<20W） . But in the first 30 seconds of discharge startup, Pi can be reached 100W.
This characteristic is tend to active some resistance loads which shows a remarkably increase in resistance
value along with increase of the temperature, such as bulbs.
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
For example: discharge a pack of 20V lithium battery at 7A
R = 20V / 7A = 2.85Ω
P = 20V×7A = 140W

Discharge Lithium battery. The left side of the first line set the type of battery
(LiPo, Lilo or LiFe) and the value on the right side shows the final discharge
voltage of each cell. The value on the left side of second line sets the
charge current and the value on the right side of second line sets the cell
count and voltage of the battery pack. After setting the current and voltage,

The number of cells you set and the processor detects. The left side of the
first line 'R:xxSER' shows the number of cells detected by the iCharger and
the right side of the first line 'S:xxSER' is the number of cells set by the user.
Usually, the auto-detect number won't lower than the number set by the
user. If the numbers are different you should make sure that the configured
number and the actual number for the battery are the same and then you
can start charging by pressing Start/Enter. If not, press Batt type/Stop to
go back to the previous screen and adjust the setting.
Discharge process. The iCharger allow its user to alter the discharging
current during the process. Press Start/Enter to make the discharge current
blink then press Inc to increase or press Dec to decrease the value and
press Start/Enter to confirm the alteration. You can stop discharging at any
time by pressing Batt type/Stop. Press Inc to display each cell's voltage
