Hollyland Spares - Li-ion Battery Pack 700 (for Wireless Tally System)

The Hollyland Li-ion Battery Pack 700 (Model: HL-BAT700) is the official OEM replacement power cell engineered to run Hollyland Wireless Tally System receiver lights, as well as the Solidcom C1 and Solidcom C1 Pro intercom series.

During live multi-camera broadcasts and multi-day studio recordings, camera operators rely entirely on their on-camera tally lamps to know when they are live (Program) or queued up next (Preview). This detachable, high-performance battery pack swaps out in a matter of seconds, allowing you to instantly refresh an on-camera tally light without pausing the live stream or studio production.

Core Energy & Power Management Features

• High-Efficiency Lithium Polymer Chemistry: Utilizing advanced Li-Po cells, this battery delivers a tightly regulated 4.35V voltage curve. This ensures your tally lamps maintain steady wireless connectivity and uniform LED brightness even when the cell capacity drops below 15%.

• Extended 8-Hour Performance Lifecycle: Calibrated precisely for live multi-camera environments. A single cell keeps an active on-camera tally light functioning continuously for over 8 hours on a full charge, comfortably outlasting the duration of standard live events and television broadcast schedules.

• Broad Temperature Resiliency: Built to withstand various production conditions, the battery operates safely in working temperatures ranging from 0 Cto 45C 32F to 113F) and can be stored in extreme environments from -20C to 60C.

• Featherweight, Low-Profile Footprint: Weighing next to nothing, this compact battery slides entirely inside the tally light housing. This ensures that the tally light (weighing just 98.5g with the battery installed) remains extremely lightweight, preventing it from adding top-heavy strain to mirrorless cameras, camcorders, or field monitors.

Cross-System Interoperability

This battery pack features custom structural alignment channels and specific electrical contact tabs, making it fully interchangeable across Hollyland’s flagship live production ecosystems:

• Tally Infrastructure: Hollyland Wireless Tally System (individual camera-mounted Tally Lights).

• Intercom Infrastructure: Solidcom C1 and Solidcom C1 Pro wireless crew headsets.

• Charging Infrastructure: Fits natively into Hollyland’s 4-slot and 8-slot multi-dock charging base stations.

Technical Specifications Matrix

On-Set Live Broadcast Fleet Management Tip: Because the Wireless Tally System and the Solidcom C1 intercoms utilize the exact same HL-BAT700 battery model, you have a massive advantage in hot-swapping logistics. Keep your tally batteries and headset batteries organized in a single central charging station. If a camera operator's tally light runs low during a lengthy live broadcast, you can instantly swap it out using a spare cell from the intercom fleet, simplifying your on-set power inventory and minimizing gear clutter in your production kit.
