Hollyland Spares - NP-F970 Battery (for Mars & Cosmo Series)

The Hollyland Spares - NP-F970 Battery is a high-capacity, rechargeable lithium-ion power cell designed to serve as the heavy-duty power source for Hollyland's wireless video transmission systems, specifically across the Mars and Cosmo series.

Relying on the industry-standard Sony L-series form factor, the NP-F970 represents the largest physical capacity tier in this battery family, offering extended operation times to keep video villages, director's monitors, and on-camera transmitters active through intensive shoot schedules.

Key Performance & Structural Features

• Maximum Runtime Capacity: As a 970-tier cell, it utilizes a thick-profile dual-row interior composition to deliver up to three times the operational capacity of standard, slimmer NP-F550 or F750 batteries.

• Broad System Interoperability: Engineered to perfectly lock into the integrated battery plates of Hollyland hardware, including the Mars 300 Pro, Mars 400S Pro, Mars 4K, Mars M1 Enhanced Monitor, as well as the production-grade Cosmo C1 wireless ecosystem.

• Tactile LED Power Status Gauge: Features an integrated push-button check mechanism paired with four physical LED indicator lights on the top shell casing. This allows technicians to instantly verify remaining capacity before mounting the cell to a rigged transmitter.

• Intelligent Cell Stabilization: Reinforced with an internal protection circuit module (PCM) that actively defends the lithium chemistry against short circuits, over-charging voltage spikes, and localized overheating during high-draw transmissions.

Expected Operational Runtime Windows

Because Hollyland transmitters and receiver monitors pull varying wattages based on their processing chips, fan cooling speed, and signal ranges, real-world runtime scales accordingly when utilizing a single fresh NP-F970 cell:

• Mars 300 Pro / 400S Pro Transmitters: Approx. 7 to 9 Hours of continuous wireless transmission.

• Mars 4K Ultra-HD Transmitters: Approx. 5 to 6 Hours (due to enhanced 4K encoder chip processing loads).

• Mars M1 / M1 Enhanced wireless monitors: Approx. 3.5 to 4.5 Hours (as the battery simultaneously powers both the internal wireless chipset and the high-brightness touchscreen panel).

On-Set Rigging Weight Advisory: While the NP-F970 provides maximum longevity, it is significantly heavier and physically deeper than smaller L-series cells. When rigging an ultra-lightweight on-camera transmitter (like a Mars 300 Pro) to a compact gimbal setup or minor mirrorless camera hot-shoe, consider utilizing an NP-F750 instead to maintain stabilization balance, reserving the heavy NP-F970 sticks for stationary field monitors and director's cages.
