a) Settings on the charger (general)
The charger must display the main menu.
• In the main menu (Programme Select), use the STATUS - (5) and (18) or (4)
and (21) buttons for the respective charging channel to select the respective sub-menu and
confirm the selection with one of the ENTER buttons (3) and (20).
• Use the STATUS - and/or buttons to select the various settings.
• To change a value or setting, press the ENTER button. The display flashes.
• Now, modify the value flashing on the display with the STATUS - and/or buttons.
• To quickly change a value (e.g. the charging current), press and hold the respective button.
• Save the (modified) value with the ENTER button.
• Press the STOP button (6) and (19) to return to the previous menu. Pressing this button
several times returns you to the main menu.
b) Operation using the software
You can connect a computer to the charger to then operate the charger using the software;
operation is analogous to operation on the charger itself. You can also display a graphical
representation of the waveform.
• To do this, install the software from the CD-ROM on a computer. Start the ‘setup’ file from
the CD-ROM and follow the installation instructions.
• Connect your computer to the charger using the first connection PC Link (2) and a USB
cable.
The second connection, PC Link (2), is used to update the charger firmware when
the manufacturer makes firmware updates available.
• Connect the charger to a power supply.
You can obtain a mini USB connection cable for the data connection from Conrad
using item no. 1360264.
• Went you have installed the ‘ChargeMaster’ software and started it up, you can easily
control the functions of the charger using the software.

Charging programmes
• Use the STATUS - buttons (5) and (18) or buttons (4) and (21) to select the
battery type that matches the battery being used (LiPo, Li-ion, LiFe or LiHV). Confirm
the selection with the ENTER buttons (3) and (20) for each charging channel with the
corresponding button.
• Then, use the and STATUS - buttons to select the various battery programmes:
- ‘BALANCE’: Charge lithium batteries with balancer connection
- ‘CHARGE’: charge all batteries (including lithium batteries without balancer connection)
- ‘FAST CHG’: Fast charge for lithium batteries
- "STORAGE": Charge/discharge a lithium battery to a certain voltage (e.g. for storage)
(this function can only be used with lithium batteries)
- ‘RE-PEAK’: Recharge batteries several times (NiMH and NiCd batteries only)
- ‘AUTO-CHARGE’: Automatically charge batteries (NiMH and NiCd batteries only)
- "CYCLE": Discharge and charge batteries cyclically several times (NiMH and NiCd bat-
teries only)
- "DISCHARGE": Discharge batteries (all batteries)
• Press and hold the ENTER button for more than 3 seconds to start the set operating
option.
• Press the STOP button (6) and (19) to return to the previous menu. Pressing this button
several times returns you to the main menu.
a) Programmes for lithium batteries (LiPo, Li-ion, LiFe, LiHV)
The battery programmes are used to charge and discharge lithium batteries with a rated
voltage of 3.7 V, 3.3 V and 3.8 V per cell. They differ only in the voltages and the permissible
charging current. When charging a lithium battery, there are two distinct phases. During the first
stage, the battery is charged with a constant current. When the maximum voltage is reached
(e.g. 4.2 V for a LiPo battery), the voltage is kept constant, which causes the charging current to
fall. When the charging current drops below a certain threshold, the battery stops charging and
the charging process is complete. The charging current varies according to the battery capacity
and performance. The final charging voltage is also very important and must be precisely
matched to the charging voltage of the battery. These are 4.2 V for LiPo, 3.6 V for LiFe, 4.1 V
for Li-ion and 4.35 V for LiHV batteries. The charging current and rated voltage as well as the
number of cells must be set correctly in order for the battery to be charged.
If the battery has a balancer connection (this is the case for nearly all lithium batteries
with more than one cell), the balancer connection must also be connected to the
charger during the charging/discharging cycle (in addition to the battery connection
cable).
There are different types of balancer connector. Do not attempt to force the plug into
the charger if it does not fit. If necessary, purchase a suitable adapter to connect the
balancer connector to the charger.
On some occasions, batteries with more than one cell have separate connections for
each cell. These batteries are not strictly speaking ‘multi-cell’ batteries. It is therefore
essential that you observe the battery manufacturer’s information concerning the
type and rated voltage.
When you use a multi-cell battery pack, a balancer (built into the charger) is the
only way to ensure that all cells have the same voltage after the charging cycle is
complete and to prevent the cells from overcharging (risk of fire or explosion) or
deep discharge (damages the battery).
The charging current to be set depends on the battery capacity and type. Always
refer to the specifications in the manufacturer's instructions.
Charging a lithium battery with the balance programme ‘BALANCE’
This programme is used to equalise the voltage of the individual cells of a lithium polymer
battery pack during charging. When charging with a balancer, a balancer cable must be used.
In this programme, the charging process differs from normal charging insofar as the charger’s
internal processor monitors the voltages of each individual cell in the battery pack. The voltage
of each individual cell in a multi-cell lithium battery is monitored and in the event of deviations is
corrected accordingly so that each battery cell is charged to the same voltage.
Use balancer cables when charging lithium batteries in balancer mode.
In addition to the two conventional battery connections (po and negative/-), the balancer
connection on the battery must also be connected to the charger.
Ensure the correct polarity when connecting the balancer connector to the battery. The negative
terminal of the balancer connection usually has a black cable or is specially marked. This side
of the balancer connector must point towards the ‘-’ of the charger's balancer socket and must
also be connected to this connector pin.
When using self-assembled batteries, always ensure that the balancer connector is
connected correctly.
The black/marked cable is the negative terminal of the first cell. The next connection
pin is the positive terminal of the first cell; the subsequent connection pins are the
positive terminals of the second, third, fourth, fifth and sixth cells (depending on the
number of cells).
The last connection pin on the balancer connector is the positive terminal of the
last cell. This means that the voltage between the two outer pins on the balancer
connector is the same as the voltage on the two battery connections.
