Spektrum™ Smart Technology is all about providing a higher connection to your hobby. It's an RC ecosystem that gives you complete control over your model, while making key components of your model easier than ever to use. Smart Technology ensures that all of your model's electronics work together seamlessly for maximum efficiency and performance. It keeps you informed of the status of each component, increases your confidence in its capabilities, and makes your entire system more responsive and easier to use.

Spectrum radios with smart features can instantly download firmware updates via Wi-Fi and exchange firmware with compatible radios via Bluetooth. Spektrum Smart LiPo batteries have a built-in microchip that automatically records your charging preferences and sends them to the Smart chargers - just plug in your battery and press "Start". The Smart IC™ series connectors include an innovative data cable that can easily transfer information between Smart components with a single connection. Finally, Smart ESCs not only provide power, but also eliminate the problems of running telemetry. The days of installing and connecting multiple wires, sensors, modules and connections are over.

The Spektrum™ Micro 4 Smart charger is a 4-port tool for the RC pilot who wants the ultimate 1S LiPo battery charger. Equipped with Spektrum Smart Charging technology, its digital LED status screen provides important battery information in clear form as soon as you make the connection. Its compact all-in-one design offers an incredible four independent charging channels, each with enough built-in connections to make charging multiple 1S batteries with the highest precision easy.

Each of the four charging channels is equipped with independent circuitry to improve charging precision and efficiency. The vivid LED status lighting includes individual 4-digit displays and multi-coloured LEDs, so you can instantly see the charging phase and battery status. The simple pressure selector interface allows fine tuning of charge rates from 0.05 to 1.2A, allowing fast charging of most high rated batteries. Exclusive software automatically detects LiPo and LiHV 1S batteries, combined with Spectrum Smart Charging technology, so that your batteries receive maximum protection against short circuit, overcurrent, reverse polarity and input voltage errors.

The Micro 4 AC/DC system works when plugged into a standard wall outlet, or you can even take the Micro 4 charger with you. Unlike charging several 1S batteries in parallel, each battery is individually detected. This allows you to charge individual 1S batteries with the precision of much more expensive chargers and possibly extend the life of all your 1S batteries.

Four precision charging terminals
Four individual charging circuits and four separate charging connections enable precise charging of several 1S packs. Select the precise charge rate you need, from 0.05 to 1.2 amps, using the individual dials, combined with a 4-digit display and a multi-colour status LED system, so you can have a fleet of batteries working for you.

Easy to use
Simply connect your 1S battery to one of the charging ports and the Micro 4 will immediately display the battery voltage. The Micro 4 is conveniently powered from a standard 120V outlet or a remote power source. Its push-button rotary knob makes it easy to program all four charging ports, while LED indicators clearly show charge status, rate, voltage and more.

Compact design
Each of the four connections has four connector types to choose from, so there are no cumbersome adapters to untangle. Thanks to its light weight and small size, it is even easier to pack the device in a backpack and take it everywhere.
