Instructions

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 initiated. The battery internal
resistance can slightly vary under dierent 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 change of current to
occur during charging.

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.
If battery voltage is lower than storage voltage, charger will charge battery to storage voltage.
If battery voltage is higher than storage voltage, charger will discharge battery to storage
voltage. In order to save storage time, battery might not be accurately balanced, this is normal
and there will not do any harm to battery.

Activation and restoration functions of excessive discharged battery
When the charging task begins, one tenth of the setting 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.
