The four-channel GT POWER X4 mini 4x100W charger was designed with the aim of providing everything needed to charge up to four batteries simultaneously "under one roof", including the power supply and with simple operation.
X4 mini allows charging common types of cells (NiCd, NiMH, Li-poly, Li-ion, Li-Fe, Li-HV, Pb), in addition, all channels are equipped with built-in four-channel balancers, which ensure very safe and comfortable charging of lithium batteries.
The charger program is designed for practitioners who purchase the charger to charge the batteries, not to watch nice pictures on the display of a smart phone. When powered from the mains, the X4 mini offers two power allocation modes for 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 with maximum power first, while the second to fourth batteries are charged with only low power; as soon as the first battery is charged, the second, then the third and finally the fourth will start charging at maximum power. When powered by a 24 V car battery or a 19-26 V mains supply, the X4 mini has a full power of 100 W for all four channels.
Overview of basic functions and parameters
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: The charger uses a final voltage of 2.40 V / cell when charging lead-acid batteries - for this reason it is suitable for charging classic lead-acid batteries (car batteries) and gel batteries with a reversible valve. Not suitable for charging gas-tight gel batteries, which must not be charged to more than 2.30 V / cell.
The charger set includes: X4 mini charger, mains cable, instructions.
