Charger XTAR VC2SL 10440/26650

XTAR VC2SL charger for 10440-26650 USB Li-ION/ Ni-MH/ Ni-CD 2 channels

New improved version of VC2S!

The latest innovative charger, VC2SL is a smart device for charging various Li-ION, Ni-MH and Ni-CD cells. The charger can charge, different cells at the same time. It automatically recognizes the type of battery (manufacturing technology), and displays the information on an easy-to-read VA LCD display. The device automatically adjusts the voltage and current delivered to the batteries in three automatic stages (TC-CC-CV) to ensure optimal charging of the batteries with minimal consumption of the cells. It has no manual change of charging current. We can read all selected parameters cyclically on the display: CAP - (charging current), IR (internal resistance) and CCR (capacity delivered in real time). The CCR parameter is the capacity that the charger has delivered to the cell in mAh. This allows you to control the charging rate in real time.

The charger can charge protected Li-ION batteries in sizes: 20700 and 21700.

TheVC2SL is more than a battery charger, it is also a power supply for multiple devices. In order to save time, we can use the USB output at the same time while charging the cells. The function: "Power Management System", allows us to charge both the batteries and power an external device at the same time while the power supply is connected. In addition, the device can be used like a Power Bank, to charge, for example, smartphones, tablets, etc.

USB output function:

• The USB output allows you to charge both batteries and external devices at the same time when the power is connected.
• While the charger becomes a Power Bank, the display shows the state of charge of the cells. While discharging the cells, we see the status from 100% to 1% and then the discharging stops automatically.

Advanced technology:

• With automatic selection of charging currents of 0.5A, 1.0A and 2.0A, the charger controls the charging speed and thus takes care of the condition of the batteries.
• It automatically detects the type of cells and lets you choose the most suitable charging method. You can use Li-ION cell charging as well as pulse charging for Ni-MH / Ni-CD batteries.
• The charging method for Li-ION cells, processor-based TC/CC/CV and Ni-MH/Ni-CD cells, processor-based CC.
• Each channel is independent, individually recognizes technologies, so Li-ION and Ni-MH/Ni-CD cells can be charged at the same time.
• Buffer technology protects the cells during the charging process.

The TC/CC/CV charging algorithm used in the charger is a charging process for Li-ION cells to ensure good cell condition. It involves charging with the right current and also completing the charge at the right time. TC/CC/CV charging stages, we can divide into:

• TC stage: the initial phase of checking and reactivating a cell whose voltage has dropped below 2.9V.
• CC stage: then the cell is charged with a constant current of 50mA to 500mA (depending on the connected power source).
• CV stage: then the charger switches to charging with decreasing current until the cell voltage reaches 4.2V. When the cell voltage reaches 4.2V, charging is complete and the battery is fully charged.

Smart VA LCD screen:

• Displays: battery charge expressed in mAh, battery voltage, charging current and internal resistance of the cell
• Recognizes and displays the type of cell being charged: Ni-MH, Li-ION or Ni-CD
• If the cell cannot be charged, the screen will show "null"
• If it detects reverse polarity or short circuit, " Err" will be displayed
• The screen backlight, will automatically go into power saving mode after 2 minutes of inactivity. To save power, the function can be turned on manually by pressing and holding the button
• As "Power bank", the display will show the voltage of the cell in the clock sensor, and the voltage of the USB port below. The current output in use is also displayed.

Reactivating discharged cells involves inserting the cell into the charger and checking the voltage. With this function, we can check each cell in the appropriate size. When a discharged cell is detected, the charger will attempt to reactivate it. Note that exceeding the minimum voltage on the cell will limit the possibility of reactivating and saving such a battery. When you leave the cell in the charger it will self-discharge. However, if the voltage on the battery drops below 3.9V for Li-ION, charging will start automatically.

An interesting and safe solution in the VC2SL charger is a separately connected power supply. This prevents unnecessary heating of the charged cell. The temperature on the cell, can rise no more than 15ºC. When the set is working, the power supply itself heats up and not the charged cell. This directly affects the life of the battery.

Thanks to the USB output of the VC2SL charger, it can serve as a Power Bank to charge Smartphones, Tablets, etc .
