vc4 is a professional processor charger with three-stage TC / CC / CV charging process and LCD display.
charges 1-4 li-ion 3.6/3.7V and ni-mh cells of any capacity, including 14650, 17670, 18350, 18500, 18650, 18700.
With two external channels, you can charge R14, R20, 20700, 21700 size batteries - only unprotected, 22650, >Xtar VC4 The LCD display shows current information about the charger's operating status: the voltage of the charged batteries, the charging current, the charge used to charge the cells, indicates errors and informs about the completion of charging. At the same time, it also shows the current operating status of both channels. It is possible to switch between the remaining two channels using the CH button on the charger body.
The Xtar VC4 charger for cylindrical Li-ion / Ni-MH AA / AAA / 18650 batteries will allow you to measure the battery capacity – to do this, discharge it to the appropriate cut-off voltage level and place it in a Ni.9.4, VC – 0 V charger. When charging is complete, you can read the value of the charge used to charge the battery on the display.
Charger Xtar VC4 A USB cable is included. However, the package does not include a power supply. To power the charger, any charger with a USB cable is sufficient, for example from a phone or USB socket or a computer with a free USB port. The VC4 will adjust the charging current according to the capabilities of the power source.

Xtar VC4 Cylindrical Battery Charger with /5-AAH /.0-AAH / / VC Charging Technology
Xtar VC4 cylindrical battery charger supports TC / CC / CV charging technology.
Charging method TC / CC / CV (Cut-off current / Constant current / Constant voltage) is a safe and effective three-stage battery charging process to keep the cells in good condition.
Here are the individual steps in this process:
- TC phase (termination current): in this phase, cells that are discharged below 2.9 are “awakened” with a lower current. This means that the current is relatively low at the beginning of the charging process in order to gently “wake up” them”the cell is deeply discharged (permanentcell)deep discharge. i 2.9 V, the process switches to the constant current phase. In this phase, the cell is charged with a constant current of 0.05 A to 0.5 A (depending on the power source). Constant current allows you to quickly charge the battery to a certain level.
- CV (Constant Voltage) phase: When the cell voltage reaches 4.2 V (which is the maximum voltage for most lithium-ion cells), the charger switches to the constant voltage phase. During this stage, the charging current gradually decreases, and the charger maintains the voltage at 4.2 V. This allows for gentle charging of the cells, while reducing the risk of overheating or damage to the battery. pl / zdjecia / 41925 / adowarka_do_akumulatorw_cylindrycznych_liion__nimh_aa__aaa__18650_xtar_vc4_e4ece1c791390.jpg “alt =” Charger functionality cylindrical li-jon / ni-mh aa / aa. “Lazy” />
