Discover our industrial-grade, standard-compliant lithium-iron phosphate modules specifically optimized for mission-critical telecommunications systems.
Modern telecommunications infrastructure is undergoing rapid evolutionary progress. As global operators roll out dense 5G network equipment, traditional macro base stations and decentralized small cells require reliable, energy-dense backup power systems. The power consumption of 5G active antenna units (AAUs) has surged significantly compared to legacy 4G systems, necessitating modern energy storage systems (ESS) that deliver higher C-rates, faster recharge, and compact footprints.
For decades, Valve Regulated Lead-Acid (VRLA) batteries were the baseline backup choice. However, their short lifespan, weight restrictions, high vulnerability to thermal runaway, and rapid capacity degradation in hot environments have rendered them obsolete. Enter Lithium Iron Phosphate (LiFePO4) battery systems. LiFePO4 chemistry stands out as the ultimate technology for telecom stations, providing safe operations, zero acid emissions, a compact 19-inch rack-mount layout, and a cycle life that outlasts lead-acid by five to ten times.
Hangzhou LIAO Technology Co., Ltd. addresses the multi-faceted challenges faced by modern telecom operators through comprehensive macro solutions. Our product range spans from low-voltage 48V telecom tower battery modules to high-voltage energy storage systems exceeding 480V for base station central hubs.
These modular lithium systems function flawlessly with smart rectifiers and solar hybrid power controllers. They support peak-shaving protocols—enabling stations to draw power from the battery during high-tariff periods and recharge during low-tariff hours, thereby optimizing Operational Expenditure (OPEX) and facilitating the transition toward carbon-neutral telecom infrastructure.

Our Research and Development teams continue to refine cell design and smart battery management. The technology roadmap at LIAO focuses on the following key areas:
Answering critical technical questions for network architects and procurement specialists.
LiFePO4 batteries deliver multiple times the lifespan of VRLA (2800+ cycles at 100% DOD compared to VRLA's 300-500 cycles). Additionally, LiFePO4 batteries are lighter, require less space, charge faster, and operate across a wider temperature range (-40°C to 85°C) without the risk of thermal runaway. This reduces battery replacements and overall operational costs for telecom operators.
Our telecom batteries feature an intelligent BMS that supports standard industrial interfaces, including RS485, RS232, and CAN bus. These protocols enable integration with base station power controllers and remote management platforms (SNMP), allowing off-site operators to monitor state of charge (SOC), cell voltage, temperature, and current real-time.
LIAO's LiFePO4 batteries are designed with advanced thermal structures and active heat dissipation channels. Operating within the recommended range of 0°C to 45°C maintains optimal performance, though our cells are rated to operate safely from -40°C to 85°C. This ensures reliability at sites without active cooling or in harsh outdoor environments.
Yes. We manufacture standard 48V telecom modules, but our design team also configures high-voltage systems (192V, 348V, and 480V) to meet the requirements of central offices, macro hubs, and larger scale microgrid installations.
Our Battery Management System (BMS) balances cells during charging, protects against over-voltage, under-voltage, over-current, and short-circuits, and regulates thermal profiles. These protections keep cells within optimal operating limits, extending the battery's life.
All our battery systems are certified under UN38.3, MSDS, CE, and IEC 62619 standards. This ensures they meet international guidelines for safe transport, mechanical integrity, and electrical reliability.
