Gold Mount Li-Ion Batteries — Professional Video Power

Block Battery's Gold Mount batteries are compatible with a broad range of professional cinema and broadcast cameras, including Sony, RED, Canon, and Arri-based rigs. Models like the Logos 150 G use Three Stud Gold Mount interfaces, while the Protean supports Gold Mount, Gold Mount Plus, B-Mount, and V-Lock in a single unit.

14V batteries power most standard professional cameras, lights, and accessories, while 28V (typically regulated 28VDC or nominal 26V Gold Mount Plus) supports higher-voltage cameras like the Canon EOS C400 and certain broadcast rigs. Block Battery offers both single-voltage and dual-output models that switch between 14V and 28V to support a wide range of equipment.

Yes, provided the battery meets airline carry-on limits. Batteries under 100Wh are generally unrestricted; 100–160Wh require airline approval. Block Battery's Protean splits into two isolated 75Wh units for compliant carry-on travel, and larger block batteries like the SLi-D600 and SLi-D1000 can be disassembled to meet air travel regulations.

Runtime depends on the battery capacity and your equipment's power draw. The 150Wh Logos 150 G powers most broadcast cameras for approximately 1–2 hours at typical loads. The SLi-300 at 304Wh delivers over 2 hours for smaller cinema cameras. High-capacity systems like the SLi-D1000 at 970Wh can power cameras and accessories through a full production day.

Yes. Block Battery's SLi-300, SLi-D600, and SLi-D1000 all feature UPS mode, which allows simultaneous charging and operation. This is especially useful for studio or stationary setups where uninterrupted power is critical, ensuring your camera or light never loses power during a battery charge cycle.

Charger compatibility varies by model. The Logos 150 G requires Block Battery chargers exclusively. The SLi-300 is sold with a PSU-100 18.5 charger included, and the SLi-D600 and SLi-D1000 include chargers with rapid charger upgrades available on request. Always use the specified or included charger to protect battery health and warranty coverage.
