GT power Universal Charger X4 Mini

Detailed product description

The four-channel charger G.T. POWER X4 mini 4x100W is designed to provide everything you need to charge up to four batteries simultaneously, including a power supply, and is easy to use.

The X4 mini allows you to charge common battery types (NiCd, NiMH, Li-pol, Li-ion, Li-Fe, Li-HV, Pb), and all channels are equipped with built-in four-channel balancers that ensure very safe and comfortable charging of lithium batteries.

When powered from the mains, the X4 mini offers two power allocation modes for the channels - either the same power is available for all channels (max. 25 W for each or max. 100 W when using only one channel). Or the first connected battery is charged at maximum power first, while the second to fourth are charged at only a small power; once the first battery is charged, the second, then the third, and finally the fourth, are charged at maximum power. When powered by a 24 V car battery or a 19-26 V mains adapter, the X4 mini has a full 100 W power for all four channels.

Overview of basic functions and parameters:

• Input supply voltage 19 - 26 V DC
• Mains supply 100-240 V / 50-60 Hz
• For charging 1 - 8 NiCd / NiMH cells, 1 - 4 Li-ion / Li-poly / Li-Fe / LiHV cells or 2-14 V lead-acid batteries
• Adjustable charging current (0.1 A - 10.0 A)
• Max. charging power 100 W for each channel (when powered by a 24 V car battery or a 19-26 V mains adapter - to fully utilize the charger's power, the power supply must have a voltage of at least 24 V)
• Max. charging power 25 W for each channel (when powered from the mains)
• Termination of charging using automatic delta-peak for NiCd and NiMH batteries
• Lithium and Pb batteries are charged using the "constant current/constant voltage" method
• Adjustable sensitivity of delta-peak detection for NiCd and NiMH batteries
• Two charging modes for lithium batteries - fast charging and charging with an emphasis on balancing
• Termination of charging when the set time or the delivered charge is exceeded
• Memory for 10 charging programs for each channel.
• Measurement of the total voltage of the set and individual cells (for lithium batteries)
• Socket for temperature sensor
• Backlit LCD display with a simple and clear menu and display of parameters during charging
• A number of warning text messages contribute to safe operation - incorrect input voltage, incorrect connection, unsuitable battery or its condition, incorrect polarity at the output, etc.
• Protection against reverse polarity and short circuit at the output.
• Forced cooling fan.
• Compact plastic case, small dimensions
• Built-in power supply.

The charger is equipped with XT60 output sockets and universal sockets for JST-XH service connectors in all channels, allowing direct connection of battery power cables and JST-XH service connectors of 2-4S sets - if you use sets with XT60 and JST-XH connectors, you can do without charging cables and adapters.

Note: When charging lead-acid batteries, the charger uses a final voltage of 2.40 V/cell - for this reason it is suitable for charging classic lead-acid batteries (car batteries) and gel batteries with a reversible valve. It is not suitable for charging gas-tight gel batteries, which must not be charged to more than 2.30 V/cell.

The set includes: X4 mini charger, power cable, instructions.
