These details in mind, please also see the chart provided separately for a quick reference of the
estimated maximum discharge power levels/discharge current rate settings for LiPo batteries based
on the current rate and estimated voltage of the battery (and please note that these values are
approximate and may vary +/- slightly depending on ambient temperatures, state of charge/voltage
level of the battery being discharged, etc.).
Discharge Voltage Cutoff
You can set the per cell voltage cutoff that will complete/end the discharge process automatically
using this setting.
However, especially in the case of LiPo/LiIon/LiFe batteries, it is important
that you DO NOT over-discharge the batteries to a voltage that is too low as it can result in
damage to the battery. If you are unsure of the safest discharge voltage cutoff for the battery
DO NOT discharge the battery or please contact the manufacturer of the battery for more
information.
Here also are some general suggestions of the per cell voltage cutoff to use for each battery
chemistry/type to prevent over-discharge/damage:
LiPo/LiIon
3.3-3.5V per cell when discharged at rates of 1-4C
LiFe
2.6-2.8V per cell when discharged at rates of 1-4C
NiCd/NiMH
0.9-1.0V per cell when discharged at rates of 1-4C
Pb/lead-acid
1.6-1.7V per cell when discharged at rates of 1-4C
Discharging the Battery
After setting the correct battery chemistry type and cell count in the Charge Mode, then also the
correct discharge current rate and voltage cutoff in the Discharge Mode, connect the battery to the
charger properly and you are ready to begin discharging. To begin discharging simply press and
HOLD the ENTER button for a few seconds (please also note that during discharging you can press
and hold the ENTER button to end the discharge process).
If the battery is connected properly and the charger confirms that all other parameters are correct,
discharging will begin automatically.
Data Monitoring During Discharging
Throughout (and after) the discharge process you can view/monitor various data. On the main
discharging screen you will see the elapsed duration of the discharge process, the capacity that’s
been discharged from the battery, the discharge current rate and the voltage of the battery. You can
also use the +/ – buttons to switch between the various screens to see the available data.
For example, when discharging a LiPo/LiIon/LiFe battery and on the discharging screen simply press
the + button once and you will see the individual cell voltages (when balancing is turned ON). If you
press the + button a second time you’ll again see the elapsed time, as well as the internal
temperature of the charger and the peak voltage of the battery at the beginning of the discharge
process. Pressing the + button a third time will show the elapsed time in addition to the input voltage
from the power source.
From there the charger will check the battery
while displaying the following screen:
