120Wh V-Mount Lithium-Ion Batteries

The Protean offers 150 watt-hours of total capacity in a single unit. For air travel compliance, it can be split into two electrically and mechanically isolated 75Whr batteries, each meeting TSA carry-on and shipping regulations for lithium-ion batteries, giving you travel-ready flexibility without sacrificing power.

The Protean supports both 14V and 28V output modes. Users can quickly switch between the two to accommodate a wide range of professional production equipment, from cinema cameras to on-set lighting rigs rated 0–150 watts. This dual-voltage capability reduces the need to carry separate battery types on location.

Block Battery's Protean is compatible with Gold Mount (14G), Gold Mount Plus for 26V on-camera use (28G), B-Mount style (28B), and V-Lock style (14V). This broad mount compatibility makes it suitable for diverse camera systems used in cinematic, ENG, EFP, and broadcast production environments.

Yes. The Protean is designed to be travel-ready. It can be disassembled into two isolated 75Whr batteries, each falling under the 100Wh threshold required for carry-on compliance on commercial flights. This makes it ideal for location shoots and international productions where air transport of equipment is necessary.

V-Mount batteries are ideal for professional film and cinema production, broadcast journalism (ENG/EFP), commercial video shoots, and on-set lighting. Block Battery's Protean is specifically engineered for high-demand environments running professional cameras such as Alexa, Phantom, Red, and Sony CineAlta systems.

The Protean is rated for a load range of 0–150 watts, making it suitable for powering cameras, on-camera monitors, lighting fixtures, and accessories commonly used in professional production settings. Its 14V and 28V modes allow it to match the power draw of a broad range of production equipment.
