Greatest compatibility in Xtara chargers so far! Supports batteries:

3.6/3.7 Li-ion /IMR/INR/ICR and 3.2V Li-FePO4 in sizes:

• 10440 / 14430 /  14500 / 14650 / 16340 / 17335 / 17500 / 17670 / 18350 / 18490 / 18500 / 18650 / 18700 / 20700 / 21700 / 22650 / 25500 / 26650 / 32650

1.5V Li-ion in sizes:

• AAA / AA

1.2V Ni-MH in sizes:

• AAA / AA / A / SC / C / D

VX4 v2 is an advanced smart charger that automatically recognizes the type of battery inserted (except for Li-FePO4).

Additionally, it has 4 independent channels, allowing you to mix different types and sizes of batteries, with one small exception - the charger cannot simultaneously charge regular Li-ion batteries and Li-FePO4.

We can also mix the types to the maximum:

1.5V Li-ion + 3.6/3.7V Li-ion + 1.2V Ni-Mh

or

1.5V Li-ion + 3.2 Li-FePO4 + 1.2V Ni-Mh

The first charger that is able to measure the actual capacity of lithium-ion batteries 1.5V in AA and AAA sizes!

In addition to the normal charging function, the charger also has a battery testing function. This involves charging the battery to full, then discharging it (measuring the actual capacity in the process), and after the discharge process is complete, the charger recharges the batteries to full. This allows us to know the true total capacity of the battery. Mixing types is just as dependent as in the case of the charging function. Physically, we can only discharge:

1.5V Li-ion + 3.6/3.7V Li-ion + 1.2V Ni-Mh

or

1.5V Li-ion + 3.2 Li-FePO4 + 1.2V Ni-Mh

The Xtar VX4 v2 charger gives the user the ability to manually select the charging current for chosen quantities and types of batteries.
For Li-ion 1.5V and 1.2V Ni-MH batteries, the charger always charges at a current of 0.5A, while for Li-ion 3.6/3.7V and 3.2V Li-FePO4 batteries, the user can choose from a wide range of charging currents:

1x 3A / 2x 2A / 4x 1A / 4x 0.5A / 4x 0.25A - ideal current for low-capacity batteries

To fully utilize the charging capabilities of the charger, a charger compatible with PD 20W should be used.
The VX4 v2 will also work with weaker power supplies, although it will then limit the ability to charge at higher currents.

The Xtar VX4 v2 charger continuously informs the user about the basic parameters of the batteries placed in it.
Thanks to this, we can see in real-time what the charging current is, the amount of charge used to charge the battery, and the voltage present on the battery.

Exceptions are the 1.5V Li-ion batteries - here during the charging process we only see the actual charging current.

We already know that the VX4 v2 charger allows for manual adjustment of the charging current, but we must also mention that it can optimally select this current by itself.
The advanced processor will choose the appropriate charging current based on the number of batteries placed, their internal resistance, and the connected power source.

Charger Xtar VX4 v2 has the function of reactivating deeply discharged cells and cells with a voltage of 0V. Many chargers on the market are unable to charge such batteries. Here, the charger Xtar VX4 v2 comes to the rescue, which in many cases allows for the 'rescue' of such cells. Just insert the deeply discharged battery into the VX4 charger, just like with normal charging - the charger will detect the discharged cell and attempt to reactivate it.

Note! Cells discharged below a certain level may suffer irreversible damage and their reactivation may be impossible. It is advisable to avoid excessively deep discharging of Li-ion and Ni-MH batteries - this can lead to a significant reduction in their lifespan and capacity or render them completely inoperable.

What is the TC/CC/CV charging method? It is a three-stage process for charging Li-ion cells that ensures the cell remains in good condition by charging with the appropriate current at each stage and completing the charging process at the right moment.
The individual stages of the TC/CC/CV process are:

• TC Phase: cells discharged below 2.9V are 'woken up' with a lower current.
• CC Phase: after reaching 2.9V, the cell is charged with a constant current ranging from 0.1A to 3A (depending on the power source used and the number of batteries being charged).
• CV Phase: when the cell is almost fully charged, the charger switches to charging with a decreasing current until a voltage of 4.2V is reached on the cell. Once 4.2V is reached, the charging process is complete - the battery is fully charged.

The Xtar VX4 v2 charger is equipped with a range of protections, allowing you to have peace of mind and confidence that every battery will be fully and correctly charged. It features, among others, the following protections:

• short-circuit
• overcharge
• overcurrent
• reverse polarity
• voltage
• timer
• soft start
• intelligent detection
