ISDT K4 AC 400W DC 600Wx2 Charger (ISDT-K4)

Intelligent dual-channel charger ISDT K4 AC 400W DC 600Wx2

 

ISDT K4 is a powerful smart charger of the new generation with the ability to operate from both alternating current (AC) and direct current (DC) sources. The device is equipped with two independent channels, which allows you to simultaneously service two batteries with different parameters. The model supports innovative BattAir technology for automatic recognition of the battery type and control of charging parameters.
 

Advantages

1. Dual power mode (AC/DC Dual Mode)

The device is universal: it can be connected to a regular outlet (AC 100–240V) or an external power supply/car battery (DC 10–34V). In AC mode, the power is 400 W, and when connected to a DC source, it increases to 600 W per channel (total 1200 W).

 

2. Two independent channels

ISDT K4 allows you to charge two batteries simultaneously, each channel works independently. You can connect different types of batteries with different numbers of cells to the first and second ports without the risk of conflicting settings.
 

3. Support high-voltage assembly up to 8S

Unlike standard chargers, K4 supports lithium batteries from 1 to 8 cells (1~8S), covering the needs of powerful drones and large radio-controlled models.

 

4. BattAir Technology and Smart Connectivity

The charger supports BattAir technology, which provides wireless battery information exchange. The device can automatically detect the battery type and select the optimal operating algorithms. It also supports management and firmware updates via the ISD Link mobile application.
 

5. Wide compatibility

The device works with a huge range of battery chemistries: LiFe, Li-Ion, LiPo (1-8S), LiHv, ULiHv (1-7S), lead-acid Pb (1-14S) and nickel-cadmium NiMH/Cd (1-18S) batteries. This makes it a universal tool for any modeler.

 

6. Informative display

K4 is equipped with a full-color LCD display that displays all the necessary information in real time: the voltage of each bank, current, charging time, internal resistance and capacity "filled" into the battery.
