300 Watt Hour Rechargeable Battery Packs

The SLi-300 is a compact block-style battery weighing just 9 lbs, designed for shoulder-worn or light stand-mounted use on production sets. Its form factor is optimized for mobility without sacrificing capacity, making it practical for field production, location shoots, and camera rig builds using 15mm rods or ring grips.

The SLi-300 uses LiFePO4 (Lithium Iron Phosphate) chemistry. This chemistry is known for its superior thermal stability, longer cycle life, and safer discharge characteristics compared to standard lithium-ion, making it an excellent choice for professional production environments where reliability and safety are critical.

The SLi-300 is compatible with Gold Mount, V-Mount, and B-Mount eliminator plates. These plates allow the battery to offload weight from cameras and light panels while integrating seamlessly into 15mm rod rigs, ring grips, shoulder rigs, and light stands, supporting a wide range of professional cinema camera builds.

Yes. The SLi-300 features a UPS (Uninterruptible Power Supply) mode that allows simultaneous charging and operation. This means your cameras and lights will not experience any power interruption during charging transitions, which is critical for continuous shooting scenarios on professional film and commercial video productions.

Yes, the SLi-300 features a modular design that allows multiple batteries to be linked together to expand total power capacity. This is especially useful for high-demand shoots, extended location days, or powering multiple devices simultaneously, giving production crews scalable power solutions without needing additional equipment.

The SLi-300 is designed for 14V cinema cameras, LED lights, and accessories. It supports popular setups including Sony cameras, Canon DSLR/5D rigs, and RED camera systems. With a 0–150W load range and Gold, V, and B-Mount compatibility, it integrates with a broad range of professional broadcast and cinema equipment.
