Description
Freefly Systems SL4-Ground Battery
The Freefly SL4-Ground Battery is a high-performance, intelligent Lithium-Ion (Li-Ion) battery designed as a robust and long-lasting power solution primarily for Freefly MōVI Pro and MōVI Carbon gimbal stabilizers. It’s a key component of Freefly’s “SuperLight” (SL) Battery ecosystem, offering significant advantages over traditional LiPo battery systems, including enhanced safety, reliability, and integrated smart features.
Developed by Freefly Systems, the SL4-Ground Battery is engineered to meet the demanding power requirements of professional camera stabilization. Its advanced chemistry and smart features aim to extend operational runtimes and provide crucial real-time feedback, making it an indispensable component for cinematographers on set.
Key features and benefits of the Freefly SL4-Ground Battery include:
- High Capacity & Long Runtimes: With a nominal voltage of 21.6V (6s) and a capacity of 4.1 Ah (86.4 Wh), the SL4-Ground battery offers significantly longer run times compared to the original MōVI Pro batteries. Depending on the camera setup and accessory load, it can power a MōVI Pro for 2 to 5.75 hours.
- Lithium-Ion (Li-Ion) Chemistry: Utilizes advanced Li-Ion cells (specifically Lishen LR2170SF) for more reliable performance, improved safety, and a longer overall lifespan compared to traditional LiPo batteries.
- Smart Battery Features with Integrated Display: Equipped with an onboard screen that displays real-time vital information such as voltage, power output, lifetime charge cycles, and remaining charge status. This provides operators with immediate and accurate insights into battery health and performance.
- Onboard USB-C Power Delivery (PD) Output: Features a built-in USB-C port that can supply up to 60 watts of power (up to 3A at 5V, 9V, 12V, 15V, or 20V). This allows operators to directly power or charge other USB-C devices like laptops, phones, or monitors from the battery, streamlining their power setup.
- Rapid Charging Capability: When paired with a Freefly SL Battery Charger (USB C) and a compatible 100W+ USB-C PD power brick (sold separately), the SL4-Ground battery can be fully recharged in approximately 70 minutes.
- Rugged and Weather-Resistant Design: Built to withstand the rigors of professional production environments, featuring a 1-meter drop rating and resistance to moderate rain (up to ~3 mm/minute). It operates across a wide ambient temperature range of -20°C to 50°C.
- Compact & Lightweight: Weighing approximately 600g (1.3 lbs), its design balances capacity with portability, making it practical for extended handheld operations.
- Seamless MōVI Pro/Carbon Integration: Designed to work with MōVI Pro and MōVI Carbon when used with the specific MōVI Pro to SL Battery Adapter (sold separately). Freefly also provides API and CAD data for custom integrations, allowing it to be used with other Freefly systems or custom builds.
The Freefly SL4-Ground Battery is an essential MōVI Pro accessory and a superior gimbal power solution that significantly enhances the reliability, runtime, and versatility of Freefly MōVI stabilizers. It’s a critical investment for cinematographers demanding peak performance and robust power management on professional sets.
