6. Selecting the Charging Current
The charging current must be set first before
charging the battery. To do so, set the charging
current for the battery (300...3,000 mA) with the
rotary knob on the front of the charger.
1C means capacity value = charging current.
• Example: LiPo/NiMH cell at 1500 mAh;
1C = 1500 mA (= 1.5 A) charging current
This is the correct charging current for the most
commonly used types of lithium/NiMH battery.
Higher capacity battery packs can, of course,
also be charged. In this case, the required charg-
ing time will increase accordingly.
Certain batteries can be charged at a higher or
lower charging rate than 1C. Pay attention to the
information provided by the battery manufac-
turer!
Charging time at 1C: LiPo approx. 1.5 h, NiMH
approx. 1h
7. Charging LiPo Batteries
A lithium battery pack
must
be charged w i t h
the voltage sensor lead connected. Exception: 1
LiPo cell.
• Ensure the polarity and position are correct
when connecting the voltage sensor lead.
The black wire of the sensor lead must be
aligned with the arrow mark on the charger
casing.
• Ensuring correct polarity, now connect the
main power cables of the battery to the con-
nection at the charger (red = +/black = -).
•
Start the charging operation by pressing
and holding the Start button. The battery
voltage is checked and the number of cells
determined in the first 10 seconds. The
charging process can be stopped at any
time by pressing the Start button again.
• While charging the LiPo battery, the total
voltage, charging current and charged
capacity are shown alternately in the LC
display
.
• The battery is equalised during the char-
ging process
.
The equalizer LEDs indicate the status of the
connected cells. Constantly flashing or lit LEDs
indicate that the cells are being balanced. The
LEDs only flashing sporadically or off indicate
that the battery is balanced and is ready for use.
The lithium battery pack is charged with a con-
stant charging current until the end of charge
voltage of 4.2 V per cell (B) is reached. The volt-
age is then kept constant and the remainder of
the charging process takes place in the form of a
descending power curve (C) down to the switch-
off point (D). Charging current = C/10. The end
of charge is signalled by the status LED chang-
ing colour to orange and the beeper sounding.
The battery can now be disconnected from the
charger and used.
