iCharger Synchronous Balance Charger/Discharger 208B
Discharging a Lithium battery
In this mode, you can set the target per-cell voltage and hence the final voltage (final voltage=cell
voltage*number of cells). The lowest allowable cell voltage depends on the type of Lithium battery: 2.50V for
Lilo, 3.00V for LiPo and 2.00V for LiFe per cell. If the battery is connected to the balance port, the
iCharger
can
monitor the individual cell voltages. The discharge will stop immediately if any cell falls below the
configured final voltage.
Note:
If you connect the balance port at the beginning of the discharging process, then the balance port will
monitor each cell‘s voltage, if one of these cells‘ voltage reaches the termination voltage then the process will
terminate with ―balance port low cel vol‖. For example in LiPo mode, if one cell‘s voltage reaches 3.0V the
process will stop.
If you want to avoid this ―balance port low cell vol‖ message, then you can connect the balance port after the
discharge process has started. In that case the process won‘t monitor each cell‘s voltage, just the pack‘s
voltage and the discharge process will terminate when the pack voltage reaches the termination voltage (=
target_cell_voltage x number_of_cells). For example in LiPo mode, the discharge process won‘t terminate
until the pack‘s voltage reach N*3.0V.
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,
press
Start/Enter
for more than 3 seconds to start the next process.

The number of cells you set and the processor detects. If the checking
result is the same, it would enter to the next interface; if not the same, 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. 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
