Gold Mount Batteries 14.4V

A 14.4V battery operates at a nominal voltage of 14.4 volts, commonly referred to as a 14V battery in professional cinema and broadcast contexts. Block Battery's Gold Mount 14.4V batteries are designed to power 14V cameras, LED lights, and a wide range of production accessories used in film, broadcast, and ENG/EFP workflows.

Block Battery offers the Logos 150 G (150Wh, Three Stud/Gold Mount on-board battery), The Protean (150Wh, multi-mount including Gold Mount, V-Mount, and B-Mount with 14V/28V switching), and the SLi-300 (304Wh LiFePO4 block battery compatible with Gold Mount via eliminator plates).

The Protean is specifically designed for travel — it splits into two electrically isolated 75Wh batteries, meeting carry-on and shipping lithium battery regulations. The Logos 150 G and SLi-300 are subject to standard DOT, IATA, and IMO lithium battery transport regulations and are not designed to disassemble for air travel.

Yes. The Protean and SLi-300 are compatible with Gold Mount, V-Mount, and B-Mount systems via interchangeable configurations or eliminator plates. The Logos 150 G is specifically designed for Three Stud (Gold Mount) mounts. The VMA-4XLR adapter also allows Gold Mount batteries to power V-Mount and B-Mount cameras.

Yes. The SLi-300 features a UPS (Uninterruptible Power Supply) mode that allows simultaneous charging and powering of connected devices without interrupting the power supply. This makes it ideal for studio and location shoots where continuous, uninterrupted power delivery is critical.

The highest capacity option is the SLi-300, a 304Wh battery that uses LiFePO4 (lithium iron phosphate) chemistry. It weighs only 9 lbs and is compatible with Gold Mount, V-Mount, and B-Mount systems via eliminator plates, making it well-suited for demanding cinema and broadcast productions.

Yes. The SLi-300 features a modular design that allows multiple units to be linked together for expanded energy capacity. This makes it an excellent solution for extended shoots, high-draw lighting equipment, or productions requiring long-duration uninterrupted power without battery swaps.
