Professional Fast Processor Charger Professional processor loader with three-stage charging process TC/CC/CV. The Xtar VP4 loads standard Li-ion 3.6/3.7 V cells in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650, 32650. The largest battery sizes, i.e. 22650, 26650 and 32650 can only be charged in two extreme channels.
Xtar VP4
Up to 1-4 rechargeable Li-ion batteries in 18650 sizes and other
• Fast-Maximum charging current 1A!
• Three charging currents selectable 0, 25A/0, 5A/1A
• LCD Display
• Reactivation function of deeply discharged cells
• Protection: Short-circuit, thermal, reverse polarity
The charging current is determined jointly for all channels with the button above the display. When charging 1-2 batteries in the extreme channels, the maximum charging current is 1A. However, when charging 3-4 batteries or placing a single battery in one of the two central channels, the maximum charging current is 0, 5A.
The Xtar VP4 is equipped with an LCD display that informs about the charging current, the charging progress and the current battery voltage.
What Is THE TC/CC/CV charging method? It is a three-step process of loading Li-ion cells to keep the cell in good condition by charging the right current at each stage and completing the charging process at the right moment.
The various stages of the TC/CC/CV process are:
• TC phase: Cells discharged below 2, 9V are ' awake ' to lower currents.
• CC phase: When 2, 9V is reached, the cell is loaded with a constant current and voltage of the value selected by the user (default 0, 25A).
• CV phase: When the cell is already almost charged, the charger switches to a decreasing current charge until the correct voltage is reached on the cell. When it is reached, the charging process is complete-the battery is fully charged.
When left in the charger, the charged batteries will be subjected to a natural self-discharge process. Charging will resume when the battery voltage drops below 3.9 v.
The Xtar VP4 Charger has a function of reactivating deeply discharged cells and cells with a Voltage Of 0v. Many chargers on the market are not able to charge such batteries. Here with the help comes the charger Xtar VP4, which in many cases allows you to ' resave ' such cells. Just insert a deeply discharged battery into the VP4 charger, as with normal charging, the charger detects the unloaded link and attempts to reactivate it. Attention! Cells unloaded below a certain level are irreversible and reactivated may not be possible. Avoid too deep discharge of Li-ion batteries-this can lead to a significant reduction in their durability and capacity or to their total malfunction.
Chargers from other manufacturers can significantly increase the temperature of the cells being charged during charging. Excessive heating of the cells can cause them to wear more quickly. When designing the VP4 charger, Xtar went one step further from the competition, solving this problem easily: the power supply from an external power supply was applied. This ensures that the charging temperature in the VP4 battery rises by up to 15 degrees.
Supplied with the Xtar VP4 charger, you GET an EU-plug adaptor and a cigarette lighter cable
