SKY RC T400Q charger 4x100W

The four-channel SKY RC T400Q 4x100W charger was designed with the aim of providing everything needed to charge up to four accumulators simultaneously "under one roof", including a mains supply and with simple operation. The compact "tower" box ensures that the charger takes up minimal space on your desk. Unlike unlike many competing devices, the T400Q has the same performance on both mains and car battery power, so you can be sure you're always charging at the same speed.

The T400Q allows you to charge and discharge common types of cells (NiCd, NiMH, Li-poly, Li-ion, Li-Fe, Li-HV, Pb), in addition, all four channels are equipped with built-in six-channel balancers that ensure very safe and comfortable charging of lithium accumulators.

It differs from ordinary 50-100W chargers with really intelligent software, which enables the functions usual for "machines" of much higher price categories, but at the same time it is designed for practical users who buy the charger to charge batteries, not to watch pretty pictures on the display of a smart telephone:

• program for new types of "high voltage" lithium batteries LiHV with terminal voltage for charging up to 4.35 V
• setting the end voltage for charging and discharging for lithium batteries (allows gentler charging, which is liked by aviators, or, on the contrary, brutal overcharging, which is adored by "car enthusiasts")
• programs for charging maintenance-free lead AGM batteries and charging lead batteries at low temperatures
• measurement of total voltage and voltage of individual cells (for lithium batteries) even outside of charging/discharging
• measuring the internal resistance of the entire set and individual cells (for lithium batteries)

Overview of basic functions and parameters

• Input supply voltage 11 – 18 V DC
• Mains supply 100-240 V/50-60 Hz
• For charging and discharging 1 – 15 NiCd/NiMH cells, 1 – 6 Li-ion/Li-poly/Li-Fe/LiHV cells or 2-20 V lead-acid batteries with liquid electrolyte and maintenance-free AGM
• Adjustable charging current (0.1 A - 12.0 A)
• Adjustable discharge current (0.1 A - 2.0 A)
• Max. 100 W charging power for each channel
• Max. power for discharging 10 W
• Automatic charge and discharge mode for NiCd, NiMH with adjustable current limit
• Termination of charging using automatic delta-peak for NiCd and NiMH accumulators
• Lithium and Pb batteries are charged using the "constant current/constant voltage" method
• Adjustable delta-peak detection sensitivity for NiCd and NiMH batteries
• Adjustable terminal voltage for charging and discharging for lithium and lead-acid batteries
• Repeated cyclic charge/discharge or discharge/charge operation for NiCd and NiMH batteries, up to 5 cycles
• Three charging modes for lithium batteries - fast charging, balancing charging and storage charging/discharging
• Three charging modes for lead-acid batteries - for normal lead-acid "car batteries", for lead-acid AGM batteries (batteries with electrodes separated by a glass fiber separator impregnated with electrolyte) and for charging lead-acid batteries at low temperatures (-20°C to +5°C).
• Termination of charging when the set time or the supplied charge is exceeded
• Memory for 10 charge/discharge programs for each channel.
• Measurement of the total voltage of the set and individual cells (for lithium batteries)
• Measurement of the total internal resistance of the set and individual cells (for lithium batteries)
• Backlit LCD display with a simple and clear menu and display of parameters during charging/discharging
• A number of warning text messages contribute to safe operation – wrong input voltage, wrong connection, unsuitable battery or its condition, wrong polarity at the output, etc.
• Protection against reverse polarity and short circuit at the output.
• Fan for forced cooling.
• Compact plastic box, small dimensions
• Built-in power supply.

The charger is equipped with XT60 output sockets in all four channels and universal sockets for JST-XH service connectors allowing direct connection of battery power cables and JST-XH service connectors of 2-6S kits - if you use kits with XT60 and JST-XH connectors, you can completely avoid without charging cables and adapters. You can use standard Sky RC or RC System adapters to connect the service connectors of other systems.

Note: When charging lead-acid batteries, the charger uses a final voltage of 2.40 V/cell (or 2.45 V/cell in the program for AGM batteries and in the program for cold charging) - for this reason, it is suitable for charging classic lead-acid batteries (car batteries) and gel accumulators with a reversible valve. It is not suitable for charging gas-tight gel batteries, which must not be charged at more than 2.30 V/cell.

The charger set includes: T400Q charger, mains cable, manual.
