In high-stakes production environments where continuous power is not a luxury but a necessity, only the most capable batteries can keep up. Enter the Rolux Density III — a 290Wh V-Mount battery designed for the most demanding gear, extended runtimes, and advanced multi-device setups.
Whether you’re running power-hungry cinema cameras, broadcast systems, or an entire rig of lights and accessories, the Density III ensures reliable, high-capacity performance without compromise.
Massive 290Wh Capacity. No Interruptions.
With 290Wh (14.4V / 20100mAh) of energy, the Density III is built for all-day shooting, powering 6K/8K cinema cameras, field monitors, wireless systems, and more — all from a single compact unit. It’s perfect for long-form content, multi-location shoots, and gear-intensive setups that require consistent, uninterrupted power.
Advanced Multi-Port Power Interface
The Density III isn’t just a high-capacity battery — it’s a complete power distribution hub, offering multiple professional-grade and consumer-friendly output options:
- BP Electrodes: 14.4V / 15A out, 16.8V / 3A in
- D-Tap (Bi-directional): 14.4V / 15A out, 16.8V / 3A in
- USB-C PD: Up to 65W output (ideal for laptops, USB-C cameras, and tablets) & 45W input for rapid charging
- USB-A: 5V / 2.1A output for smaller accessories
With these ports, the Density III can charge or power cine gear, mobile devices, field tools, and even laptops — all at once. It’s a central power station you can mount on your rig.
Built for the Field. Designed for Reality.
The Density III is engineered to perform in extreme environments, with a working temperature range of -10°C to 60°C, making it suitable for both arctic locations and desert landscapes. A charging range of 0°C to 40°C keeps it safe for fast top-ups under controlled conditions.
And despite its high capacity, the battery stays relatively compact with two size variants:
- 120 × 91 × 90mm
- 120 × 91 × 102mm
With a weight of only 1380g–1390g, it balances power and portability perfectly for camera operators, DPs, and gaffers on the move.
