The charger automatically sets the charge current of 1C based on this information.
When you connect the pack to the charger and start the charge process, the charge current
starts at 0.00 A and slowly rises to the set limit.However, please do not be surprised if the
charger does not reach the current you have set, because the charge program constantly
monitors the battery voltage in order to prevent the pack inflating, provided that the voltage of
the individual cells in the pack is the same.When the charger automatically reduces the charge
current, the screen displays the message END, alternating with the reduced charge current.

care to set the correct cell

make a mistake, the battery
could explode and burst into

Lithium manual program
This program charges the battery using the capacity
(charge current) which you set.
Before you initiate the actual program you must set the
charging current (range 0.1A...8.0A, left of the screen)

and the capacity of the pack (range 50...8000 mAh, right
INC DEC
on the screen) using the INC / DEC buttons. Switch
between the charge current and the capacity parameters
by using the ENTER button.
If the charged capacity reaches 110% of the adjusted
capacity, the charging process is stopped for safety
reasons.
Lithium discharge program
The purpose of this program is to determine the residual
capacity of a Lithium pack which has not been fully
discharged.
+
- The program discharges the pack using the set discharge

current (0.10 ... 5.00 A, left of screen) down to the set final
discharge voltage (2.5 ... 3.7 V per cell, right of screen). It
is not possible to set a final discharge voltage below 2.5 V
per cell, otherwise the battery will suffer permanent
damage.
Lithium cell count
When you have connected the battery to the charger, hold
the START button pressed in for about two seconds and
7 . 7 3 V )
the screen will display the cell count of the Lithium pack. If
the pack contains 1 or 2 cells, the charger detects and
sets the number of cells fully automatically. If the pack
contains more than two cells, you may have to adjust the
cell count manually using the INC / DEC buttons, as the
automatic circuit is unable to detect more than three cells
reliably. On the right-hand side you will see the voltage of
the pack connected to the charger. Pressing the START
button again initiates the charge process.
