When selecting the storage function, the UP616 will automatically begin charging if the
battery pack voltage is below the ideal storage voltage. Likewise, the UP616 will
automatically enter the discharge mode if the battery pack voltage is higher than the ideal
storage voltage.
Storage
If the UP616 detects internal cell voltages that are too low to safely begin the charging
process, it will automatically default to a 0.1A charge rate until the voltage has risen to a
level that allows it to safely accept a fast charge rate.
The UP616 features the ability to monitor the internal resistance 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 that
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.
