Professional Video Camera Batteries

Professional camcorders and ENG/EFP cameras typically use rechargeable lithium-ion battery packs in Gold Mount or V-Mount configurations at 14V. Block Battery offers 150Wh to 970Wh+ options to suit everything from compact broadcast camcorders to high-demand cinema rigs requiring extended runtime in the field.

V-Mount (V-Lock) and Gold Mount (Anton Bauer) are the two dominant battery mounting standards in professional video production. V-Mount uses a V-shaped locking mechanism, while Gold Mount uses a three-stud design. Both support 14V operation; compatibility depends on your specific camera brand and model. Block Battery offers batteries for both standards.

Yes, but lithium battery air travel compliance depends on watt-hour capacity. Batteries under 100Wh are generally permitted as carry-on without airline approval; 100–160Wh require approval. Block Battery's Protean (splits to 2×75Wh) and SLi-D600/SLi-D1000 feature disassemblable designs specifically engineered for airline-compliant carry-on transport.

UPS (Uninterruptible Power Supply) mode allows a battery to charge and power connected devices simultaneously without interrupting the power supply. This is critical on set, as it prevents cameras and equipment from shutting down mid-shoot when swapping to a charger or AC power source. Several Block Battery models including the SLi-300 and SLi-D600 support UPS mode.

Runtime depends on your camera and accessory power draw. A 150Wh battery powers most smaller cinema cameras for over an hour; 300–600Wh covers most production days without recharging. For all-day shoots with 28V cameras and lights, the SLi-D1000 at 970Wh or Artisan Block at 900+Wh are designed to eliminate mid-day battery swaps.

Yes. Block Battery systems are explicitly compatible with Sony FX9, RED cinema cameras, and Canon EOS C400, among others. Products like the SLi-D600, SLi-D1000, and the Protean support both 14V and 28V outputs via V-Mount and B-Mount configurations, covering the power requirements of these professional cinema camera platforms.
