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 infl ating, 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.

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...10.0 A, left of the screen) and the capacity
of the pack (range 50...20.000 mAh, right 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 capa-
city of a Lithium pack which has not been fully discharged.
The program discharges the pack using the set discharge cur-
rent (0.1 ... 5.0 A, left of screen) down to the set fi nal discharge
voltage (2.5 ... 3.7 V per cell, right of screen). It is not possible
to set a fi nal discharge voltage below 2.5 V per cell, otherwise
2 . 5 V / C
the battery will suffer permanent damage.

Lithium storage program
This program does charge or discharge the battery to the best
storage voltage.
The program does charge or discharge the battery to the
adjusted storage voltage, which is best for longer storage of
a Li-battery.
Best store voltage:
LiPo: 3,8...3,9V/cell
