Discharging A Lithium Battery - iCharger 106B+ User Manual

iCharger Synchronous Balance Charger/Discharger

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.

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,

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
(see the balance voltage information) and press Dec to display the
