Product Overview; Operation - VOLTCRAFT V-Charge 2S QUAD Bedienungsanleitung

• Do not use the product in the immediate vicinity of strong magnetic or
electromagnetic fields, transmitter aerials or HF generators. These may affect the
electronic control system.
• Do not place the product directly next to devices with strong electrical or magnetic
fields (e.g. transformers, motors, cordless telephones, wireless devices and
radios), as these can prevent the product from working properly.
• Never use the product immediately after it has been brought from a cold room into
a warm one. This may generate condensation, which can cause the product to
malfunction or damage the interior components. It may also cause a fatal electric
shock! Let the product reach room temperature before using it. This may take
several hours.
• If you do not plan to use the product for an extended period (e.g. storage), discon-
nect the product from the power supply. To do this, disconnect the power cable
from the mains socket.
• Trained personnel must supervise the use of electrical appliances in schools, trai-
ning facilities and DIY workshops.
• For installations in industrial facilities, follow the accident prevention regulations
for electrical systems and equipment issued by the government safety organisati-
on or the corresponding authority for your country.
e) Electrical safety
• Before connecting the product to the mains, ensure that your local mains voltage
matches the specifications on the product nameplate.
• The product must only be powered with a properly fused earthed socket
(230 V/AC, 50 Hz) or a suitable DC voltage source (7–17 V/DC).
• The mains socket must be located near to the device and be easily accessible.
• For safety reasons, disconnect the mains plug from the mains socket during
thunderstorms.
• Never connect or disconnect power plugs when your hands are wet.
Information about charging parameters
Rechargeable batteries consists of two electrodes which are contained in an electrolyte. A
rechargeable battery is therefore a chemical element. Chemical reactions take place inside
this element. These reactions are reversible, which makes it possible to recharge the battery.
To charge a rechargeable battery, a so-called charge voltage is required, which must exceed
the cell voltage. Moreover, the energy supplied during the charging process must be higher
than that which can be drawn afterwards. This ratio of the energy supplied to the energy drawn
is called efficiency.
The capacity that can be drawn is heavily dependent on the discharging current and has a
decisive impact on the condition of the battery. The supplied charge cannot be used as a mea-
sure, because some of it will be lost during charging (e.g. converted into heat).
The capacity data given by the manufacturer is the maximum theoretical quantity of current
which can be delivered by the battery. This means that a 2000 mAh battery can theoretically de-
liver a current of 1000 mA (= 1 A) for two hours. The actual value depends heavily on numerous
factors (e.g. condition of the battery, discharging current and temperature).
a) Selecting the charging parameters
All parameters must be set correctly before each charge. Using incorrect settings
can cause a fire and injury as well as damage to property.
b) Selecting the charging current
An excessive charging current significantly reduces the lifespan of the battery, and in extreme
cases may cause a fire or explosion. Selecting the appropriate charging current for a battery
type is therefore very important. The charging and discharging current are determined by
the C-coefficient of a battery pack. For most conventional battery packs, the C-coefficient is
indicated on the nameplate.
The requisite charging current for a battery is calculated according to the following formula:
Capacity in mA x C-coefficient = charging current in mA
Example: 1000 mAh x 5C = 5000 mA
A 1000 mAh battery with a coefficient of 5C requires a charging current of approx. 5 A.
If you can't determine the C-coefficient of a battery pack, always use a coefficient of 1C and
calculate the charging current accordingly. This is always a safe charging current. However,
bear in mind that the charging times can vary according to the actual (but not verified) battery
specifications.
For batteries with only one cell, the C coefficient is 1.

Operation

a) Placement
• Place the charger with the plastic feet on a non-combustible, heat-resistant surface close to
a standard fused mains socket, if you wish to use it with a mains voltage. To use the charger
with a DC voltage, the DC source must be located nearby or moved next to the charger.
• Keep the charger away from flammable or combustible materials (e.g. curtains). Never
operate the charger on car seats, carpet or other combustible materials.
b) Connecting to the power supply
Never operate the charger with a voltage that is outside the range specified in the
technical data.
• Alternating current connection: Connect the mains cable to the 100–240 V/AC mains
connection (1) and plug the mains plug into a standard mains socket.
• Direct current connection: Connect the 7–17 V/DC voltage connection (8) to a suitable DC
voltage source (e.g. laboratory power adapter) using a suitable cable with an XT60 plug
(not included) (see "Technical data"). You can use power adapters or, in dry conditions, car
batteries. However, consider the charging status of your car battery when you are travelling.
We recommend a battery with 2-4S and 7–17 V/DC voltage as a DC supply.
The charger has no short-circuit protection at the input. Never connect both power
supply connections simultaneously. Do not attempt to operate the charger with an
AC voltage and a DC voltage (e.g. a battery) at the same time. This will cause the
charger to switch off and start repeatedly. This may damage the AC power supply, or
in the worst case, destroy the charger.
c) Setting the parameters
• When the charger is connected to a power supply, it briefly shows the device logo and type,
followed by the value of the input voltage. The 4 LED indicators light up in red and green
until the charger switches to the standby display.
Setting the charging current
• Press the SELECT button (2) to switch to the default setting for the charging current. The
factory default setting is 0.5 A.
• Press the SETTING button (7) to adjust the charging current setting between 0.1 and 1.0 A.
Press and hold the SETTING button (7) to confirm the setting. "SAVE SETTING ..." will
appear on the LCD display (6) to confirm that your setting has been saved. The charger will
then switch back to the standby display.
