ISDT is renowned for its ergonomically designed, small, state-of-the-art battery chargers and accessories. The K4 smart charger continues this great pedigree of efficient and user-friendly chargers.

The ISDT K4 is a simple to use, yet powerful, no-nonsense dual input (AC/DC) charger that can charge two battery packs simultaneously. It has the ability to charge 2 x 8S LiPo, LiIon, or LiFe, 7S LiHV, 14S Pb, or 18S NiMh/NiCd battery packs at up to 20A. Also, each channel can operate independently of each other, meaning that two different sizes or different chemistry batteries can be charged at the same time. You can even combine both channels in parallel for synchronous balance charging to achieve even more output power. The max charging current on AC power is 400W per channel, and on DC power it is an incredible 600W per channel. The six programming keys (3 per channel) are simple and intuitive to use in conjunction with the color LCD display screen.

To cater for better cooling, the unit has a carefully designed, and optimized internal structure. This is coupled with a ball-raced fan to promote an active cooling system. Outputs include 2 x XT60 male connectors for charging, 2 x XH-JST 8S balance ports, and a micro USB port for updates. The power input of 10~34V (DC) is connected to the charger via a female XT60 connector, and for AC use a mains power lead with an EU plug is supplied.
