For filmmakers, broadcast operators, and content creators who rely on stable and long-lasting power, the Rolux Density II 140Wh USB-C V-Mount Battery brings an ideal balance of capacity, versatility, and modern connectivity. Designed as an upgrade over compact 98Wh units, this 140Wh model delivers extended runtime while maintaining a portable form factor suited for both mobile and studio environments.
Higher Capacity for Longer Shoots
The Density II is equipped with 145Wh / 10.05Ah of energy, giving cameras, field monitors, wireless systems, and portable lights more operating time between charges. With its 14.4V rated capacity, it integrates seamlessly into professional V-mount ecosystems used across cinema and broadcast workflows.
Weighing approximately 790g (±10g), it provides noticeably more endurance without imposing significant weight on handheld rigs or shoulder setups. The familiar compact dimensions of 120 × 91 × 55 mm ensure it fits comfortably into existing cases, chargers, and camera plates.
Flexible Power Outputs for Modern Gear
What makes the Density II stand out is its ability to power both traditional filmmaking equipment and modern digital devices. Multiple output options provide a flexible all-in-one power solution on set:
BP Electrode Interface
- Output: 14.4V 15A
- Input: 16.8V 3A
D-Tap Port
- Output: 14.4V 15A
- Input: 16.8V 3A
This dual-purpose D-Tap offers strong current delivery for high-draw accessories such as monitors, transmitters, or compact LED fixtures.
USB-C Power Delivery
- Output: Up to 65W
- Input: Up to 45W
With PD capability, the battery supports charging laptops, mirrorless cameras, action cams, tablets, and more—making it incredibly useful for modern multi-device workflows.
USB-A Output
- 5V 2.1A
Ideal for powering small accessories or charging mobile devices.
Together, these ports transform the Density II into a mobile power hub, cutting down the need for extra chargers and adapters on set.
Reliable in Extreme Environments
Whether you’re filming in winter conditions or under blazing sun, the Density II is built to withstand harsh environments. It functions smoothly within a wide working temperature range of -10°C to 60°C, allowing dependable performance on challenging outdoor shoots.
Charging is safe and efficient between 0°C and 40°C, helping maintain cell health and ensuring long-term reliability.
Built for Professional Demands
The Density II features a rugged V-mount construction that ensures a secure fit and stable connection on all compatible cameras and accessories. Its internal power management system helps maintain safe operation, while the overall build quality reflects Rolux’s commitment to reliable on-set performance.
This battery is especially valuable for:
- Documentary filmmaking
- ENG and broadcast work
- High-draw cinema rigs
- Multi-device setups requiring USB-C support
- Shoots that demand long runtime without frequent battery swaps
