GRUNDSÄTZE DES SICHEREN BETRIEBS

• Lassen Sie die Akkus während des Ladens/Entladens nie unbeaufsichtigt. Kurzschlüsse oder versehentliches Überladen (des für Schnellladen ungeeigneten oder mit Überstrom geladenen Akkus) können ein Ausströmen von aggressiven Chemikalien, Explosion oder Brand verursachen.
• Während des Ladens überprüfen Sie die Akku-Temperatur durch Berühren. Am Ende des Ladevorgangs kann der Akku leicht warm werden (ca. 40°C, aber er darf nicht heiß sein – in diesem Fall unterbrechen Sie sofort den Ladevorgang und trennen den Akku vom Ladegerät).
• VERSUCHEN SIE NICHT, andere Akku- oder Batterietypen zu laden, als die, für die das Ladegerät bestimmt sind – nur Nickel-Cadmium-, Nickel-Metallhydrid-, Lithium-Polymer- (LiPo und LiHV), Lithium-Ionen-, Lithiumphosphat- (LiFePO4) und Blei-Gel-Akkus mit Zellenanzahl gemäß den Angaben in dieser Anleitung.
• Versuchen Sie nie, die folgenden Akku- oder Batterietypen zu laden/entladen:
• Akkus, die aus Zellen verschiedener Typen (oder verschiedener Marken) bestehen.
• Trockenbatterien.
• Akkus, die einen anderen Lademodus als LiPo, LiIon, LiFe, LiHV, NiMH, NiCd, Pb erfordern.
• Defekte oder beschädigte Akkus
• Akkus mit integrierter Lade- und Schutzschaltung.
• In einem Gerät installierte oder an ein anderes Gerät angeschlossene Akkus.
• Akkus, die vom Hersteller nicht speziell für ein Schnellladen entwickelt wurden.
• Versuchen Sie nicht, Akkus mit einem zu großen Strom zu laden, der in keinem Verhältnis zu seinem Typ oder seiner Kapazität besteht. Befolgen Sie bei der Auswahl des Ladestroms immer die vom Akkuhersteller empfohlener Anleitung.
• Lassen Sie kein Wasser, keine Feuchtigkeit oder Fremdkörper in das Ladegerät gelangen.
• Die zulässige Netzversorgungsspannung beträgt 100-240 V/50-60 Hz oder DC 11-18 V (Autobatterie). Das Ladegerät darf nicht gleichzeitig mit Netzspannung und Batteriespannung betrieben werden.
• Legen Sie das Ladegerät auf eine feste, ebene und nicht brennbare Oberfläche.
• Legen Sie das Ladegerät und den Akku während des Ladevorgangs nicht auf brennbare Gegenstände oder in deren Nähe. Achten Sie auf Gardinen, Teppiche, Tischtücher usw.
• Decken Sie die Kühlöffnungen am Ladegerätgehäuse nicht ab – es könnte durch Erhitzung beschädigt werden.
• Zur Stromversorgung des Ladegeräts verwenden Sie nicht Ladegeräte, die zum Laden von Autobatterien bestimmt sind.
• Wenn Sie den Akku nach Verwendung (Flug oder Fahrt) laden, lassen Sie ihn zuerst auf Umgebungstemperatur abkühlen.
• Schließen Sie immer zuerst das Ladegerät an die Versorgungsquelle und erst dann an den zu ladenden Akku.
• Zerlegen Sie das Ladegerät nicht!
• Laden Sie nicht im geschlossenen Innenraum eines Fahrzeugs und schon gar nicht während der Fahrt.
• Das Ladegerät darf nicht von Kindern unter 14 Jahren oder von Personen betrieben werden, die nicht in die ordnungsgemäße Bedienung des Geräts und den Umgang mit den Akkus eingewiesen sind. Es sei denn, die Aufsicht eines Erwachsenen, der mit der Funktion des Ladegeräts und der Ladepraxis des Akkus vertraut ist, ist während des gesamten Betriebs anwesend.

Confirming the charging current

Make sure to know the maximum charging current of the battery before charging, never use excessive current to charge to damage your battery, which will result in over heat even explosion during the charging process. The charging and discharging rate of battery is usually marked with C value. Multiplying the charging C value and battery capacity equals to the maximum charging current supported by the battery. For example, for a 5000 mAh battery with a charging rate of 1C, the maximum charging current would be 5000*1= 5000 mA; therefore, the maximum charging current is 5A.

For a lithium battery, if it is impossible to confirm the supported charging C value, please set the charging current below 1C, for the sake of its (lithium battery) safety (the same applies to NiMH/NiCd batteries; no more than 0.1C for Pb batteries).

Task settings

Power on the charger and connect a battery; the charger will enter into the standby page. Short press the roller wheel to activate the program setting menu Program setting menu. The items in this menu are as follows:

Battery	Battery type selection
Cells	Select number of cells in the battery pack
Mode	Working Mode: Charge, Discharge, Storage (lithium batteries only)
Current	Select desired charge/discharge current: 0.1-10.0 A
TVC	Terminal voltage control setting
Charge channel	Allows simultaneous charging of identical pack in both two channels
Start	Start charging/discharging program
Back	Return to previous screen or function

Charging channel

This setting is convenient for charging multiple identical batteries (same type and number of cells, same capacity). You can select the channel to be started. Red indicates selected, and gray indicates not selected.

For example: When identical batteries are connected to both two channels, you can set both 1 and 2 to red; the charger will charge both packs simultaneously with the same setting.

Note: If the batteries are not identical (same type and number of cells, same capacity) you to select the corresponding channel to set and start the charging separately for each battery.

Connecting the battery

Connect the charging leads to the respective XT60 output socket (CH1 or CH2) observing the correct polarity: (+) red cable, (-) black cable. For lithium packs, it is highly recommended to ALWAYS connect the balance leads and utilize balanced charging to ensure that the charger can accurately monitor the voltage of each cell.

Storage

When selecting the Storage function, the charger will automatically begin charging if the battery pack voltage is below the ideal storage voltage. Likewise, the charger will automatically enter the discharge mode if the battery pack voltage is higher than the ideal storage voltage.

Restoring an excessively discharged lithium battery pack

Restoring an Excessively Discharged Lithium Battery pack If the charger detects individual cell voltages that are too low to safely begin the regular charging process, it will automatically default to 0.5 A charge rate until the voltage has risen to a level that allows it to accept a fast charge rate safely.

Measuring internal resistance

The charger features the ability to monitor the internal resistance (IR) of each cell in a lithium battery pack. This feature is only operational when in the balance charging mode. Internal resistance can be useful to determine the overall “health” and performance of a lithium battery; the closer the IR values are between the cells in the battery pack, the better the battery will deliver its energy.

Note: The process of charging a lithium battery is dynamic; therefore you will notice fluctuations in both charge current and IR during the charging process.

Due to the different measurement methods of the battery resistance, it is impossible to achieve the absolute data similar to professional resistance measurement instruments. Therefore, the internal resistance value is only suitable for reference with horizontal comparison, such as judging the consistency of the performance of one battery as time goes by or the performance comparison between different batteries. The charging current has some influence on the accuracy of the internal resistance measurement; a large capacity and low internal resistance battery requires a large charging current to accurately measure the internal resistance.

Working parameteres display

Rotating the roller wheel up or down during charging will switch the information displayed on the lower half of the LCD screen between cell voltage, cell internal resistance (IR) and working parameters. Cell voltage and IR can only be displayed during the balance charging process.

Dual independent output channels, setting and work independently as follows: Channel 1 charging, Channel 2 stand-by.

The colour LCD display clearly shows the working status of both two channels in real time.

Power distribution:

DC input: 2x 100 W each; each channel has a maximum of 100 W

DC power supply

The charger may also be used as 17.5 V/max. 100 W DC power supply. In the AC input mode, you can connect an appliance (a LED lamp etc.) to the XT60 DC input socket. Check the specification of your device - be sure the device may be operated at 17.5 V AND the required input power is lower than 100 W (5.5 A). Due to the limited output power of the internal AC power supply you should not use the charger for charging in the same time, especially if the appliance was an inductive load (like an electric motor; its starting current might be 5–12 times higher than the regular running current).

Warnings and errors messages
