iSDT K4 2x 200/600W

iSDT K4 is a powerful dual-channel charger capable of charging up to 8S LiPo batteries. The charger features a built-in power supply, allowing it to be powered directly from a wall outlet. For field charging, it can also be powered from an external source or a battery. When powered from AC, the total output is limited to 400W, while with a DC source the charger can deliver up to 2×600W. Each channel supports a charging current range of 0.2–20A and a discharging current of 0.2–3A (max. 30W per channel). In parallel charging mode, it can reach up to 800W (35A). The charger is equipped with XT60 and JST-XH (2–8S) connectors, so no additional adapters are needed.

K4 supports all common battery types – LiPo, LiHV, ULiHV, Li-ion, LiFe, NiCd, NiMH and Pb – and includes a powerful balancer with up to 1.5A per cell. It also offers internal resistance measurement, storage charging and discharging. The charger is equipped with a USB-C port providing 5V output for charging action cameras or phones. The USB port is also used for firmware updates. Channel 1 can work as a stabilized power supply with adjustable voltage from 2–30V and current from 1.0–5.0A.

The charger is controlled via buttons, and all information is shown on a color LCD display. The K4 also supports Bluetooth connectivity within the BattAir system, allowing monitoring and parameter adjustment via the app.
