Lingtech Battery Successfully Delivers 20ft 3MWh/1MW Integrated Liquid Cooling BESS with Flexible Voltage Output

Lingtech Battery, a leading global provider of integrated energy storage solutions, today announced the successful delivery of a 20-foot containerized Battery Energy Storage System (BESS) featuring a 3MWh capacity and 1MW power output. This state-of-the-art system incorporates an advanced integrated liquid cooling solution, delivering enhanced safety, efficiency, and operational lifespan for commercial and industrial (C&I) applications.

The AC+DC integrated system represents a major step forward in Lingtech’s commitment to turnkey energy storage, a field in which the company has been recognized as a leading Chinese integrator offering comprehensive manufacturing and system assembly. By combining the DC battery modules with the AC power conversion system within a single container, Lingtech minimizes on-site installation complexity and reduces project risks, ensuring a truly end-to-end solution for global clients.

Advanced Thermal Management and Output Flexibility

At the core of this new BESS unit is an intelligent liquid cooling system. Unlike traditional air-cooling methods, this liquid-based thermal management ensures exceptional temperature uniformity across all battery cells—a critical factor for maintaining battery health, extending cycle life, and preventing thermal runaway in high-density energy environments.

The system is designed to meet diverse grid connection requirements. While it features a standard 400V AC output, the configuration can be customized with an optional step-up transformer to accommodate higher voltage levels, including 800V and 11kV. This flexibility allows the storage system to integrate seamlessly into medium-voltage industrial power networks, making it an ideal solution for factories, EV charging hubs, and large-scale commercial complexes with significant energy demands.

Industry-Leading Integration and Standards

Lingtech’s expertise extends beyond battery manufacturing to full-system integration. The 20ft BESS unit is a self-contained solution, integrating DC battery racks, AC inverters, switchgear, fire suppression, HVAC, and smart Energy Management Systems (EMS) within a robust, IP-rated container. Built to ISO standards for global shipping, the system ensures durability and reliability in diverse environmental conditions.

With the delivery of this 3MWh liquid-cooled system, Lingtech continues to demonstrate our capacity to provide ready-to-deploy, high-performance energy storage. By offering flexible voltage outputs and advanced thermal management, we empower our clients to optimize their energy costs and achieve energy independence.
