			==== Charging channel ====
			This setting is convenient for charging multiple identical batteries (same type and number of cells, same capacity). You can select the channel to be started. Red indicates selected, and gray indicates not selected.

			For example: When identical batteries are connected to both two channels, you can set both 1 and 2 to red; the charger will charge both packs simultaneously with the same setting.

			{{Note\|'''Note:''' If the batteries are not identical (same type and number of cells, same capacity) you to select the corresponding channel to set and start the charging separately for each battery.\|type=info}}

			==== Connecting the battery ====
			Connect the charging leads to the respective XT60 output socket (CH1 or CH2) observing the correct polarity: (+) red cable, (-) black cable. For lithium packs, it is highly recommended to ALWAYS connect the balance leads and utilize balanced charging to ensure that the charger can accurately monitor the voltage of each cell.

			==== 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 ====
			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\|'''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.\|type=info}}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.

			=== Working parameteres display ===
			Rotating the roller wheel up or down during charging will switch the information displayed on the lower half of the LCD screen between cell voltage, cell internal resistance (IR) and working parameters. Cell voltage and IR can only be displayed during the balance charging process.

			Dual independent output channels, setting and work independently as follows: Channel 1 charging, Channel 2 stand-by.

			The colour LCD display clearly shows the working status of both two channels in real time.
