The charger is equipped with a function of measuring the cells’ internal resistance,
which is only applied when conducting balanced charging. The cell voltage should be
measured and calculated within 2 to 3 minutes after the charging task has been initiat-
ed. The battery internal resistance can slightly vary under different electric quantities
while the measured resistance value is usually relatively low as the electric quantity is
large.
The charging current should be adjusted instantly as the charger measures the
internal resistance of the battery; therefore, it is normal phenomenon for acute
Internal resistance measurement function
The working mode of the charger is series charging; you must therefore connect it to the
output line of the battery while charging. For a lithium battery, it is highly suggested that the
balanced interface should be connected to carry out balanced charging to accurately
monitor the voltage of each cell and balance the ones with bad consistency.
When selecting storage functions, automatic charging task can be initiated if the
battery is lower than the preset storage voltage; likewise, automatic discharging task
can be initiated if the battery voltage is higher than the preset storage voltage. To save
time during charging and discharging tasks, the voltages of cells should not be
accurately balanced; however, it is normal phenomenon that there may be some errors
between cell voltage and preset value as the tasks are completed[Unclear (very

Activation and restoration functions of excessive discharged battery
When the charging task begins, a 0.1 A current should be applied to activate and
restore the battery if the cell voltage is tested to be lower than the pre-charge voltage;
on the other hand, it should be adjusted to a rated voltage for charging when the cell
voltage is higher than the pre-charge voltage. This design can protect excessively
discharged batteries, as well as conduct activation and restoration.
