Storage
When selecting the Storage function, the charger will automatically begin charging if the battery pack voltage is below the
ideal storage voltage. Likewise, the charger will automatically enter the discharge mode if the battery pack voltage is higher
than the ideal storage voltage.
Restoring an Excessively Discharged Lithium Battery pack
If the charger detects individual cell voltages that are too low to safely begin the regular charging process, it will automatically
default to 0.5 A charge rate until the voltage has risen to a level that allows it to accept a fast charge rate safely.
Measuring Internal Resistance
The charger features the ability to monitor the internal resistance (IR) of each cell in a lithium battery pack. This feature is
only operational when in the balance charging mode. Internal resistance can be useful to determine the overall “health” and
performance of a lithium battery; the closer the IR values are between the cells in the battery pack, the better the battery will
deliver its energy.
Note:
The process of charging a lithium battery is dynamic; therefore you will notice fluctuations in both charge current and
IR during the charging process.
Due to the different measurement methods of the battery resistance, it is impossible to achieve the absolute data similar to
professional resistance measurement instruments. Therefore, the internal resistance value is only suitable for reference with
horizontal comparison, such as judging the consistency of the performance of one battery as time goes by or the performance
comparison between different batteries. The charging current has some influence on the accuracy of the internal resistance
measurement; a large capacity and low internal resistance battery requires a large charging current to accurately measure
the internal resistance.
