Slim V Mount Lithium-Ion Batteries

A slim V mount lithium-ion battery is a compact, lightweight power source that attaches to cameras, monitors, and production equipment via a V-lock style mount. Designed for professional cinema and broadcast use, slim V mount batteries offer high energy density, reduced weight, and compatibility with a range of production gear while maintaining industry-standard mounting interfaces.

Block Battery's slim V mount batteries, such as the Protean, support both 14V and 28V outputs. This dual-voltage capability allows a single battery to power a wide range of production equipment — from on-camera accessories to high-draw lights — without needing separate battery units for different voltage requirements.

Yes, when configured correctly. The Block Battery Protean splits into two electrically and mechanically isolated 75Whr batteries, each falling under the 100Wh FAA carry-on threshold. This travel-ready design ensures compliance with TSA and airline lithium battery regulations, making it ideal for location shoots and international productions requiring air travel.

Slim V mount batteries are compatible with professional cinema and broadcast cameras, on-camera monitors, LED lights, wireless transmitters, and other production accessories. The Block Battery Protean also supports Gold Mount, Gold Mount Plus, and B-Mount configurations, making it one of the most versatile multi-mount power solutions available for professional productions.

14V mode powers standard on-camera accessories and most professional cameras, while 28V mode delivers higher voltage for demanding equipment like certain cinema cameras and high-wattage lights. The Block Battery Protean allows quick switching between both modes, eliminating the need to carry separate battery units for different voltage requirements on set.

Yes. Slim V mount batteries like the Block Battery Protean are rated for loads from 0 to 150 watts, making them suitable for powering both cameras and production lights. The available D-Tap output on select configurations provides additional connectivity for accessories, offering a single versatile power source across your entire production kit.
