The overall display information of the charger screen is shown in the figure above, including the cell voltage value information of channel 1 and channel 2 connected to the battery, the charging information of the charger, and the charger version number. The contents of the red frame are as follows,

The red box 1-2 is the voltage value of the cell connected to the battery, in mV. The voltage value of the series cell can be displayed. Specifically, it contains two parts, one is the cell serial number, as shown in the figure above, 1-25 corresponds to cell 1 to cell 25, and the other part is the cell voltage value, the font is displayed in bold. In addition, the number of cells displayed will be automatically adjusted according to the actual number of connected battery cells.

Red frame 3, for the charging power display, in W.

Red box 4, which is the power display of the battery connected to the charging channel, in units of 0.1%.

The red box 5 shows the total voltage of the battery connected to the charging channel in V.

The red box 6 shows the current of the battery connected to the charging channel in A.

The red box 7 is the temperature value of the battery connected to the charging channel in °C.

Red frame 8, Chinese display for charging status information, can display charging status, power status and other information.

The red box 9 is the version number of the charger.
