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.

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.

Does a good job, but too much philosophy.
Format: Kindle
I'm about halfway through this book. I have a condition that makes it hard to read. This book does a good job of teaching SQLite but spends too much time stressing the importance of comments and style. I agree, that these things are important, however, not to the audience of the book. The reader would have been better served by getting into the grit of SQL syntax and which keywords to use when versus ensuring that every query had a comment block with name, date, and description. Moreover, requiring every reader to download a prewritten database to work from and special utilities to follow along takes away from the learning experience. That said, you will learn the basics about SQLite, and by the end of the book be able to handle most problems you'll encounter when developing an application.

Great book!
The free promotional items the company gives you just for buying this product alone make it worth the five stars I have given it, and the product itself is amazing. I should start by noting that I received this product about 5 days ago and I am currently halfway done with it. This is not a book that teaches you the very basics of computer programming and assumes that you already have a basic grasp of the fundamentals such as arrays which you definitely should if you are even the slightest bit interested in learning SQL. The book begins by teaching you about what the program is, how it is becoming a valued skill in the world, and why it is a better programming language than others. It makes a language that most people consider highly advanced and more and more difficult the more you use it very easy to grasp in a way that could potentially change your entire career. I am not a computer science expert myself and have only a basic understanding of programming language, mostly java, but I was able to read this book and understand almost all of it without a problem. My computer science friends are even surprised by how much I was able to learn about this programming language that they consider impossible in such a short amount of time. I highly recommend this product if you have any interest at all in learning a new programming language or just giving yourself another skill because they make it very simple to learn. Disclosure: I received this product for free or on a promotional discount for my honest review and they are 100% my own opinions. However everyone has their own opinion on this product. I did not receive payment other than receiving the product at a discounted rate and I am not required to give a good review. I know how important my reviews are to people who are interested in buying this product, because everyone should be reading reviews before they purchase a product. What I include is what I actually think about the product and my opinion alone. My reviews accurately reflect my views on this product and any 5 star product I would recommend to both my friends and family as well as purchase at full price. This disclosure is in accordance with the Federal Trade Commission’s Guidelines on Testimony and Advertising. I provide honest reviews that describe the product it entirety both the positive and negatives (if there are any). If my review was helpful to you, would you please vote yes!

Great beginner book but should have covered layout
Format: Kindle
I've done HTML and made an attempt to learn CSS before. This book is a GREAT choice for beginners as well as myself. The examples are pretty easy to follow and made sense. Most of all this was THE book on CSS I was looking for. My previous attempt to learn CSS was overly complicated and convoluted and left me completely confused on CSS and barely able to get the job done. Perhaps it was because it was for the specific software I was using rather than just CSS. Regardless, after this book I feel confident with CSS now and was surprised how easy it actually is when properly explained. My only complaint on this book is that I think it should have covered page layout with parent DIVs and child DIVs or page layout in general. That's definitely the next thing to learn after reading this book. But I was able to easily find a video on page layout after reading the book and took it to the next level. This book prepared me for that and got me to a place where I was ready for that. Hopefully the next version of the book will include page layout techniques to give your website a more professional look. I'm giving it 5 stars because page layout and graphic design really probably are intermediate topics. So, for an HTML and CSS book, this really "hit the spot"!
