iCharger Synchronous Balance Charger/Discharger 1010B+
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, 
the balance port must connect to the
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 
discharge power capacity(<30W). But in the first 30 seconds of discharge startup, Pi can be reached 150W. 
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. 
In Expanding Discharging Mode, if starts Regenerative discharge at the same time( see details in Page 11), 
the above stated Pi restrict will alter less than 300W. 
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 on the right side of second line, it shows AUTO. The 
system will check cell count automatically by cell balance port's voltage. 
Per-cell final voltage:
LiPo (3.00 – 4.20V), Lilo (2.50 – 4.10V), LiFe (2.00 – 3.60V)
Discharge current: 0.05 – 7A, Cell count: 1 – 10S
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 
(see the balance voltage information) and press Dec to display the 
General Status information.
