ISDT K4 Duo Dual LiPo Charger 2x600W 20A 1–8S Smart Charger AC/DC

Product description

The iSDT K4 DUO is a high-performance, premium dual charger for FPV pilots, model builders, and RC enthusiasts who want to combine maximum charging power with state-of-the-art technology. Thanks to its built-in 400W power supply, the charger can be plugged directly into a 230V outlet and delivers impressive performance even in AC mode.

When powered by an external DC source (10–34V DC), the K4 DUO unleashes its full potential, delivering up to 1,200 watts of total power or 2×600 watts of charging power. In synchronous mode, up to 800 watts of charging power is possible on a single output.

The integrated high-performance balancer, with up to 1.5A of balancing current per cell, ensures precise cell management and maximum battery life. It supports LiPo, LiHV, Li-Ion, LiFe, NiMH, NiCd, and lead-acid batteries.

The brilliant 2.8-inch IPS color display remains highly readable even in direct sunlight. Intuitive operation is provided via separate control buttons for both channels. Thanks to the built-in USB-C port, you can perform firmware updates or charge mobile devices at 5V/2A.

With its compact design and tremendous performance, the iSDT K4 DUO is one of the most powerful and versatile chargers in its class.
