iSDT K4 Charger

Order the iSDT K4 charger - it charges a wide range of battery types!

Looking for a powerful and portable drone battery charging solution? The iSDT K4 charger is your ideal companion on the airfield. This compact device combines high power of 300W with small dimensions. It is created for FPV drone pilots, racers and aircraft modellers. Indispensable when speed and mobility are important.

The device supports all popular types of lithium batteries. Works with LiPo, LiHv, LiFe, LiIon batteries. Covers the range from 1S to 8S (up to 34V). The maximum charge current reaches 15A. This is enough to quickly charge even large batteries. An external power supply is required for operation (not included). Use a power supply that is suitable for voltage and power.

Key parameters

• Power 300W: high performance in a compact package.

• Current up to 15A: fast charging of high-capacity batteries.

• Support 1-8S: Work with a wide range of drone batteries.

• Vibrant color screen: clear display of all process parameters.

• Multifunctionality: charge, discharge, balancing, storage mode, cycles.

Benefits and Features 

The main advantage of the iSDT K4 is its unique combination of power and portability. It's easy to take with you anywhere. The device weighs only about 300 grams. It will take up minimal space in your field case. 300W of power is enough for most racing and FPV batteries. Charge multiple batteries in series without any problems.

The bright color TFT display is easy to read even in direct sunlight. You see the voltage of each cell, current, capacitance. Monitor the charging process in real time. Smart features ensure battery safety. Precise balancing extends their service life. Storage mode brings the voltage to the optimal level. The Discharge function is useful for conditioning batteries.

The device is reliably protected from user errors. There is protection against polarity reversal, overheating, short circuit. Overcharge and overcurrent protection ensures safety. The simplicity of the interface makes the work intuitive. Settings are made with just a few buttons. The device supports charging from a car cigarette lighter (via power supply). This is ideal for outdoor competitions and training.
