ISDT K4 Lipo Charger - AC 400W DC 600Wx2 Dual Channel Smart Balance Charger Discharger
The ISDT K4 Lipo Charger is a high-power, dual-channel smart balance charger custom engineered for enterprise UAV battery management and high-demand FPV field charging. Capable of outputting up to 400W on AC mains power and a massive 600W x 2 on DC input, this dual channel smart balance charger is highly optimized for rapid charging, discharging, and battery health diagnostics. Its primary benefit is a dual-input AC/DC architecture combined with BattAir smart battery integration, allowing pilots to charge two high-capacity LiPo packs simultaneously with complete peace of mind.
The ISDT K4 Lipo Charger brings industrial-grade power management to commercial drone operators and RC enthusiasts. Designed to handle demanding battery maintenance routines, the K4 features dual independent channels capable of delivering up to 20A charging current per port. Its high-resolution IPS display provides real-time telemetry, including individual cell internal resistance (IR), balance voltage profiles, and temperature tracking. Whether plugged directly into a wall outlet in your workshop or connected to a high-output DC power supply at the field, the ISDT K4 delivers rapid, safe, and balanced charging across all major battery chemistries.

Frequently Ask Questions :
Q1 ) What structural benefits does the dual AC/DC input configuration provide?
Ans : The integrated 400W AC power supply eliminates the need to carry a bulky external power brick when charging at home or in the workshop. When maximum speed is needed in the field, switching to a DC power supply unlocks the full 1200W charging potential.
Q2 ) What additional accessories come packed inside the box with the ISDT K4 charger?
Ans : The factory box contains the core ISDT K4 dual charger unit, an AC wall power cable, and a quick-start instruction manual. Power output adapter leads and balance boards can be connected directly to the front XT60 and JST-XH ports.
Q3 ) Can I use standard industrial cyanoacrylate CA super glue to repair a cracked plastic case corner?
Ans : No, never use liquid CA super glues on high-power charger casings. CA glue can release conductive fumes that settle on internal high-voltage circuits, shorting the board. Use non-conductive epoxy or plastic welding techniques to repair external plastic housing.
Q4 ) Is the ISDT K4 Lipo Charger available for fast delivery across India?
Ans : Yes, this premium dual-channel charger is stocked locally and ready for fast express delivery across all states in India for commercial drone operators and hobbyists.
Q5 ) How does the ISDT K4 display and calculate battery health during a charge cycle?
Ans : The K4 continuously monitors the voltage differential across all connected cells via the balance port, calculating individual cell internal resistance (IR) in real time and displaying it on the IPS screen to help you spot degrading battery cells early.
