    Freefly SL8-Air Battery: Intelligent, travel-safe power for Astro series operations

    The Freefly SL8-Air Battery delivers efficient, intelligent energy for Astro-series drones, combining safety, performance, and portability in one compact design. Each 21.6 V / 7.3 Ah (157 Wh) lithium-ion pack integrates seamlessly with Freefly's power system to ensure consistent output and accurate telemetry throughout every mission. Designed and assembled in the USA, the SL8-Air Battery provides the reliability professionals depend on for mapping, inspection, and industrial flight operations.

    Smart energy management for reliable missions

    An integrated smart battery management system actively monitors voltage, current, and temperature to maximize safety and lifespan. The bright OLED display reports charge level, voltage, and health data at a glance, while the USB-C Power Delivery port supplies up to 60 watts for field charging of accessories. Each lightweight, airline-carry-compliant pack recharges in roughly 90 minutes, minimizing downtime between flights.

    Portable, durable, and field-ready

    At about 2.25 pounds (1.02 kg), the SL8-Air Battery balances capacity with portability. Two packs power each Astro aircraft flight, providing redundancy and extended endurance. Its rugged build withstands field conditions while maintaining dependable energy output for critical operations. Compact, smart, and travel-approved, it's engineered for professionals who require safe, efficient power anywhere missions take them.
