The high-performance two-channel charger ISDT K4 2x600W is an intelligent charger with mains and car battery power and very simple and clear operation. K4 allows you to charge and discharge common types of cells (NiCd, NiMH, LiPo, LiHV, ULiHV, Li-ion, LiFe, Pb), in addition, it is equipped with built-in six-channel balancers, which ensure safe charging of lithium batteries. The charger is equipped with a color LCD display and programming buttons, which will provide you with the possibility of comfortable and very clear setting of parameters, control and monitoring of the charging / discharging process.
In addition to small dimensions with high performance and intuitive operation, it is worth mentioning:
- program for new types of "high-voltage" lithium batteries LiHV with terminal voltage for charging up to 4.35 V and ULiHV and with terminal voltage 3.45 V
- powerful balancer with current up to 1.5 A
- possibility of synchronous operation of both channels for charging two identical accumulators or parallel charging of one accumulator with power up to 800 W
- adjustable end voltage for charging and discharging for lithium batteries (allows more gentle charging, which pilots like, or, conversely, brutal overcharging, which is enjoyed by "toy cars")
- adjustable terminal voltage for charging for lead-acid batteries (1.90-2.45 V; allows charging of all types of lead-acid batteries)
Overview of basic functions and parameters
- Mains supply 100-240 V / 50-60 Hz
- 10-34 V DC power supply (XT90 socket)
- For charging and discharging 1 - 18 NiCd / NiMH cells, 1 - 8 Li-ion / Li-poly / Li-Fe, 1 - 7 LiHV / ULiHV cells or 2- 28 V lead-acid batteries
- Adjustable charging current (0.2 A - 20.0 A) in each channel (max. 400 W when powered from the mains, max. 600 W when powered from a car battery or a powerful stabilized mains supply)
- Adjustable discharge current 0.2 A - 3.0 A in each channel
- Max. power for charging 1x 800W in parallel charging mode
- Max. power for discharging 2x 30 W, max. 1x 60 W in parallel discharging mode
- End of charging using delta-peak automation for NiCd and NiMH batteries
- Lithium and Pb batteries are charged using the "constant current / constant voltage" method
- Adjustable delta-peak detection sensitivity for NiCd and NiMH batteries
- Adjustable charging and discharging voltage for lithium and lead batteries
- Three modes for lithium batteries - charging, discharging and storage charging / discharging; all with or without a balancer. In addition, a disposal discharge mode for safe discharge of a discarded battery before it is handed over for recycling
- Channel CH1 can operate as a stabilized source with adjustable voltage 2-30 and current 1.0-5.0 A
- Easy firmware update via USB-C port; the port can be switched to the function of the power / charging socket for smartphones 5 V / 2 A
- Backlit color LCD display with simple and clear menu and display of parameters during charging / discharging
- Programming buttons for easy and clear setting and control of the charger
- A number of warning messages contribute to safe operation - incorrect input voltage, incorrect connection, unsuitable battery or its condition, incorrect polarity at the output, etc.
- Forced cooling fan.
- Compact plastic case, small dimensions
The charger is equipped with XT60 output sockets and universal sockets for JST-XH service connectors in both channels, enabling direct connection of battery power cables and JST-XH service connectors of sets 2-8S - if you use sets with XT60 and JST-XH connectors, you can do without charging cables and adapters. You can use standard Sky RC or RC System adapters to connect the service connectors of other systems / p>
The charger set includes: ISDT K4 charger, mains cable, screen protector, instructions.
