Charger Xtar VP4L+ Dragon

Xtar VP4L+ Dragon is a fast professional four-channel charger for charging Li-Ion, Ni-MH, Ni-CD cells and packs. The device has a powerbank function.

Technical specifications:

• LCD display.
• Three charging currents to choose from: 250mA, 500mA, 1000mA.
• Charging current of 1000mA only in channels 1 and 4.
• Maximum charging current total for 4 channels 2000mA, that is, inserting 4 cells we get maximum 500mA per channel.
• It has a function to reactivate cells too deeply discharged or even with "zero" voltage.
• Automatically terminates charging and resumes charging when the voltage drops
• Input voltage : 12V 1.0A
• Charging method : TC/CC/CV processor system
• Charging currents 250mA / 500mA / 1000mA
• Charging termination voltage: 4.2V ±0.05V
• Protection: thermal, short circuit, reverse battery insertion

Supported battery sizes:

• 3.6V/3.7V Li-ion/IMR/INR/ICR protected and unprotected: 10440, 14500, 14650, 16340 (RCR123), 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650, 32650
• rechargeable batteries Ni-MH/Ni-CD: AAAA / AAA / AA / A / SC / C / D
• packs: 11.1V / 3S pakiet

The TC/CC/CV charging method is a three-stage charging process for Li-ion cells that ensures that the cell remains in good condition by charging with the right current at each stage and completing the charging process at the right time. The different stages of the TC/CC/CV process are:
TC phase: cells discharged below 2.9V are 'energized' with a lower current.
CC phase: when the cell reaches 2.9V, it is charged with a constant current of 0.05A to 0.5A (depending on the power source used).
CV phase: when the cell is almost charged, the charger switches to charging with a decreasing current until the cell reaches 4.2V. When 4.2V is reached, the charging process is complete - the battery is fully charged. Left in the charger, charged batteries will undergo a natural process of self-discharge. Charging will resume when the voltage on the battery drops below 3.9V.

The Xtar VP4 charger has a function to reactivate deeply discharged cells and cells with 0V. Simply insert a deeply discharged battery into the VP4 charger as you would for normal charging - the charger will detect the discharged cell and attempt to reactivate it. Caution: cells discharged below a certain level are irreversibly damaged and reactivation may not be possible. Avoid discharging Li-ion batteries too deeply - this can significantly reduce their life and capacity or lead to their complete failure.

Included with the Xtar VP4 charger you get the following:

•     Dedicated AC adapter with EU plug
•     Car cigarette lighter cable
•     Multimeter cables for taking measurements
