Why crews come to us for mount changes
Keep your existing power on set
The VMA-4XLR adapts Gold-Mount power to B-Mount and V-Mount cameras through a 4-pin XLR output, so one power stock feeds more rigs.
One battery, several mounts
The Protean is a 150Wh battery you can order in 14G Gold Mount, 28G Gold Mount Plus, 28B B-Mount or 14V V-Lock, so you carry fewer packs.
14V and 28V together
Dual-voltage packs like the Protean, SLi-D600 and SLi-D1000 feed 14V and 28V cameras and accessories from the same battery.
Built for production loads
Robust electrical and mechanical design with high current and high capacity, supporting 14.4V, 24V, 28.8V and 30V equipment.
American made, veteran owned
Designed, manufactured and serviced in the USA by a family-owned, veteran-owned company founded in 2007.
Help choosing the right part
Technical support and custom power solutions are part of the deal. Tell us the camera and load and we will spec it.
Adapters and multi-mount batteries we build
If your battery stock is Gold Mount and your camera is V-Mount or 28V B-Mount, the VMA-4XLR adapter bridges the gap with a 4-pin XLR output. It is part of our wider power line for cinema, broadcast, ENG/EFP and lighting work.
Many crews skip adapters altogether by ordering a battery in the mount they need, or a block battery with eliminator plates. We will help you compare both routes.
- VMA-4XLR: Gold-Mount to B-Mount / V-Mount adapter with 4-pin XLR output
- Protean 150Wh battery, $275, in 14G Gold Mount, 28G Gold Mount Plus, 28B B-Mount or 14V V-Lock
- Protean splits into two isolated 75Wh batteries for carry-on travel
- SLi-300 304Wh mini block works with Gold, V and B-Mount eliminator plates
- SLi-D600 (608Wh) and SLi-D1000 (970Wh) give nominal 16V DC and regulated 28V DC at the same time
- Plate options across the line: V-Mount, Gold Mount (three-stud) and 28V B-Mount
- Multi-voltage systems support 14.4V, 24V, 28.8V and 30V for cameras, lights and accessories
- Chargers to match, including the LOGOS Quad Charger and D-Tap 14V fast charger

Frequently asked questions
Do you make a V-Mount to Gold Mount adapter?
