V-Mount Battery Pinch

The best V-Mount battery depends on your production needs. For compact, travel-friendly use, the Protean (150Wh) or SLi-300 (304Wh) are excellent choices. For high-capacity on-set power, the SLi-D600 (608Wh) or SLi-D1000 (970Wh) offer dual 14V/28V output, QuickCell modularity, and UPS mode — ideal for Sony FX9, Canon C400, and RED cinema cameras.

Not necessarily. V-Mount eliminator plates (sometimes called dummy plates) are used to offload battery weight from a camera body to an external block battery mounted on a rod rig or light stand. Block Battery's 14V Eliminator Plates are compatible with Gold, V, and B-Mount systems, enabling cleaner, more balanced camera builds without a battery seated directly on the camera.

Block Battery's V-Mount battery systems are compatible with a wide range of professional cinema and broadcast cameras, including Sony FX9, Canon EOS C400, RED cinema cameras, Arri Alexa, Phantom, and Sony CineAlta. Both 14V and 28V outputs are supported across their product lineup, ensuring compatibility with most professional on-camera and accessory power requirements.

Yes. Most Block Battery systems are designed to be disassembled for air travel compliance. The Protean splits into two isolated 75Wh batteries, well within the 100Wh per-battery carry-on threshold. The SLi-D600 and SLi-D1000 are also disassemblable to meet airline lithium battery regulations, making them suitable for location shoots worldwide.

V-Mount uses a V-shaped locking mechanism and is the most widely used standard in broadcast and cinema production. B-Mount is a heavier-duty alternative standard often used in high-current applications and certain Arri workflows. Block Battery products support both standards, and their VMA-4XLR adapter enables Gold-Mount power systems to connect to B-Mount and V-Mount cameras via 4-pin XLR output.

Yes. All Block Battery block battery systems — including the SLi-300, SLi-D600, and SLi-D1000 — feature UPS mode, which allows the battery to charge and power devices at the same time. This is particularly useful on set for continuous operation without interrupting power to cameras, lights, or other connected production equipment.
