Precision-engineered cylindrical cells optimized for portable AV devices โ delivering exceptional capacity, stable discharge and extended cycle life.
The global audio-visual entertainment device market is experiencing explosive growth driven by wireless technology adoption, content streaming proliferation and consumer demand for premium portable experiences.
The global portable AV device battery market is projected to surpass USD 12 billion by 2028, growing at a CAGR of over 9.5%. Rising demand for wireless earbuds, portable projectors, Bluetooth speakers and action cameras is the primary catalyst for this expansion.
Consumer expectations for thinner, lighter devices with longer battery life are pushing manufacturers to adopt high energy density cells (>270 Wh/kg). NCM/NCA 21700 cells have become the dominant format, replacing 18650 cells in premium AV products globally.
Asia-Pacific dominates battery supply chains, while North America and Europe are the largest AV device consumption markets. Localized ODM/OEM partnerships โ like those offered by Changhong New Energy โ are critical for brand differentiation and supply security.
AV users increasingly expect rapid recharge cycles. High-rate discharge cells (3Cโ5C) are being deployed in portable gaming devices, wireless microphones and streaming cameras, enabling fast-charge compatibility without compromising cycle life.
Regulatory requirements including UN38.3, IEC62133 and UL certifications are mandatory for AV battery products entering global markets. Double-sealing technology and 100% automated inspection processes ensure consistent safety compliance at scale.
EU battery regulations and ESG pressures are accelerating the shift to mercury-free, low-cobalt and recyclable battery chemistries. LFP cells and green manufacturing processes are becoming competitive advantages in the AV device supply chain.
In audio-visual entertainment, battery performance is not just a technical specification โ it defines the user experience. A portable Bluetooth speaker that lasts 30 hours instead of 12, a wireless camera that shoots 4K for a full day, or a VR headset that delivers seamless 8-hour sessions โ all of these are made possible by advanced high energy density lithium cells. Changhong New Energy's 21700 and 26700 series cells achieve energy densities exceeding 270 Wh/kg, enabling device designers to deliver longer runtimes without increasing device size or weight.

| Recycled / Low-Cobalt Chemistries | Regulatory push in EU/US | Compliance-ready supply chain for global AV brands | Now โ 2027 |
From concert-grade portable audio to professional broadcast cameras, high energy density lithium batteries are the invisible engine powering the most demanding AV entertainment experiences.
Delivering specialized, sophisticated, distinctive and innovative value to customers across the full spectrum of AV entertainment devices:
Domestic & international ODM/OEM services, industrial supporting solutions, national supermarket and channel distribution. Smart home devices demand batteries that combine high energy density with ultra-long cycle life and low self-discharge characteristics for always-on connectivity.
Exclusively designed for the most demanding application scenarios such as professional power tools. High-rate 18650 and 21700 cells deliver the burst current required for impact drivers, circular saws and industrial-grade cordless tools.
Capable of producing high energy density products such as ultra-high voltage batteries (4.40Vโ4.53V) and semi-solid-state batteries for precision medical instruments where reliability is non-negotiable.
Understanding the specific technical requirements of each AV device category is essential for selecting the optimal lithium cell chemistry and form factor.
Concert-grade wireless in-ear monitor (IEM) systems and wireless microphone arrays require batteries with near-zero voltage variance across discharge cycles. The NCM/NCA 21700 50SE cell's flat discharge curve ensures consistent RF output power throughout multi-hour performances, eliminating signal dropout risks during critical live events. High-temperature tolerance (up to 60ยฐC) is essential for stage environments with intense lighting.
Action cameras, drones and portable stabilizers used in extreme environments demand cells with wide operating temperature ranges (โ20ยฐC to 60ยฐC) and high vibration resistance. LFP 26700 45E cells excel in this segment due to their inherent thermal stability and 2000+ cycle life, making them cost-effective for professional content creators who charge and discharge daily.
Next-generation VR headsets running spatial computing workloads require batteries delivering sustained 15โ25W continuous power within a 200g weight budget. Ultra-high voltage 4.45Vโ4.53V NCM cells achieve the highest energy density per gram, enabling 8-hour untethered sessions. Battery management integration with AI chipsets allows adaptive power profiling based on content type and user activity level.
Ultra-short-throw laser projectors and portable cinema systems require stable high-current cells that can sustain 30โ60W laser engine loads for 3โ4 hour movie sessions. The LFP 26700 43E and 45E cells provide the thermal stability and flat discharge characteristics that prevent brightness fluctuation โ a critical quality metric for professional AV installers and home theater enthusiasts.
Professional broadcast cameras, field monitors and wireless video transmission systems used in live sports, news and entertainment broadcasting demand batteries with hot-swap capability and precise state-of-charge reporting. 18650 25T and 30T high-rate cells are widely adopted in V-mount and Gold Mount battery systems, providing the 10Aโ15A sustained discharge required for 4K/8K recording workflows.
The wearable audio market โ including bone conduction headphones, smart glasses with audio and haptic feedback wristbands โ demands the smallest possible cells with maximum energy density. Changhong's ODM capability enables custom cell configurations optimized for specific wearable form factors, supporting brand differentiation in the rapidly growing hearables and smart accessories segment projected to reach USD 90 billion by 2027.
