ISDT K4 Smart Dual Channel AC/DC Charger - 400W AC / 1200W DC (1-8S LiPo/LiHv) High Power Station
Key Technical Specifications:
Dual-Channel Independence: Two fully independent circuits mean you can charge a 6S LiPo on Channel A and a 2S Li-Ion on Channel B simultaneously with zero interference or power sharing lag.
High-Voltage 8S Support: Native support for 1S to 8S batteries, making it future-proof for the heavy-lift 8S FPV and cinematic drone platforms emerging in 2026.
Smart Ecosystem (ISD Link & BattAir): Integrated Bluetooth connectivity allows for full remote control and monitoring via the ISD Link App. When paired with BattAir-equipped batteries, the K4 automatically recognizes the cell count, type, and history, eliminating manual setup errors.
Efficient Thermal Management: Housed in a compact, durable shell with high-speed dual ball-bearing fans and an optimized air duct design, ensuring the 32-bit ARM processor stays cool during peak 20A charging cycles.
Safety Protocols: Includes comprehensive protection against over-current, over-voltage, reverse polarity, and abnormal cell counts, ensuring the longevity of your high-value battery assets.
For a high-performance power station like the ISDT K4, your FAQ should address the massive power difference between AC and DC modes, as well as the 8S capability, which is a major selling point for heavy-lift drone pilots.
Frequently Asked Questions (FAQ)
1. What is the difference between AC and DC power on the ISDT K4? The ISDT K4 is a hybrid-input charger.
AC Mode: When plugged into a standard wall outlet, it provides up to 400W of total power.
DC Mode: When connected to a high-power external battery or power supply (10V-34V), it unlocks its full potential of 1200W (600W per channel). This makes it perfect for both home use and high-speed field charging.
2. Does the ISDT K4 support 8S LiPo/LiHv batteries? Yes. Unlike many standard chargers that stop at 6S, the K4 supports up to 8S (33.6V) packs. This is ideal for professional cinema drones and industrial UAVs that utilize high-voltage 8S configurations for increased efficiency.
3. Can I charge two different types of batteries at the same time? Absolutely. The K4 features Dual Independent Channels. You can charge a 6S LiPo on Channel 1 while simultaneously charging a 4S LiHv or even a Lead-Acid (Pb) battery on Channel 2. The "Smart Sharing" technology automatically distributes the available power between the two ports.
4. How does the ISDT Link App improve the charging experience? The K4 features built-in Bluetooth connectivity. By using the ISDT Link App on your smartphone, you can monitor live charging curves, check internal resistance, and update the charger’s firmware wirelessly. This is a significant safety advantage as you can monitor battery health from a distance.
5. What safety features are integrated into the K4? ISDT has equipped the K4 with a robust safety suite, including Over-current protection, Over-voltage protection, Over-temperature protection, and Reverse polarity protection. Additionally, the dual-fan "BattAir" cooling system ensures the unit remains cool even when pushing the full 1200W limit.
Frequently Asked Questions (FAQ)
1. Why is there a difference between AC and DC power ratings? The ISDT K4 is a hybrid-input charger. When plugged into a standard wall outlet (AC), it uses its internal power supply to provide up to 400W. To unlock the full 1200W (600W per channel), you must connect it to an external DC power source (10-34V), such as a large deep-cycle battery or a high-wattage server power supply.
2. Does the K4 support the new 8S LiPo/LiHv standards? Yes. While most chargers are limited to 6S, the ISDT K4 is fully compatible with 1S to 8S Lithium batteries. This makes it a "future-proof" investment for pilots moving toward high-voltage 8S cinematic or industrial drone platforms.
3. Can I charge two different types of batteries simultaneously? Absolutely. The two channels are completely independent. You can charge an 8S LiPo on Channel A while balanced-charging a 4S LiHv or even a Lead-Acid (Pb) field battery on Channel B. The "Smart Power Allocation" ensures the charger distributes wattage efficiently between the two.
4. How does the Bluetooth "ISDT Link" app help with safety? The built-in Bluetooth allows you to pair the charger with your smartphone. Using the ISDT Link App, you can monitor real-time cell voltage and internal resistance from a distance. This is a critical safety feature, as it allows you to keep an eye on battery health without needing to stand directly over the charging station.
5. What is "BattAir" technology, and is it supported? The K4 is BattAir-supported. When used with BattAir-compatible battery clips, the charger automatically recognizes the battery type, cell count, and optimal charging parameters the moment you plug it in. This eliminates manual setup errors and significantly increases the lifespan of your battery fleet.
