The 40ft 5MWh liquid-cooled battery storage container is built for large-scale renewable energy storage, grid-side peak regulation, and shared utility energy storage power plants. It serves as a high-capacity battery unit designed for projects requiring maximum energy density, long operational lifespan, and strong system reliability.
This solution is delivered as a pure battery container without PCS or transformer equipment. It is typically paired with external power conversion and step-up systems, giving project developers more flexibility when designing large-scale energy storage stations.
The container follows a standard 20-foot structure and integrates high-density lithium iron phosphate battery modules, liquid thermal management, BMS, fire protection, and intelligent monitoring systems. Each container operates with independent liquid cooling control, helping maintain excellent temperature stability and ensuring consistent battery performance across large installations.
Key Features of the 5MWh Liquid-Cooled Battery Energy Storage Container
The container delivers up to 5.015MWh of storage capacity within a single 20-foot footprint. This high energy density significantly reduces land use, foundation requirements, and overall infrastructure cost, making it ideal for large utility-scale battery projects.
Low Auxiliary Power Consumption with Intelligent Cooling Control
The system uses variable-frequency compressors that automatically adjust cooling output based on operating load and ambient temperature. This design reduces internal power consumption by more than 15%, improving overall system efficiency and project economics.
Quiet Liquid-Cooled Battery Storage Operation
Liquid cooling replaces high-power ventilation fans found in air-cooled systems. This reduces operating noise by more than 10dB, making the container suitable for energy storage installations near urban areas or environmentally sensitive locations.
Precision Thermal Control for Long Battery Life
The liquid cooling system keeps battery cell temperature differences within 3°C across each cluster. This dramatically improves battery consistency, enhances operational safety, and reduces long-term degradation compared with air-cooled energy storage solutions.
Extended Cycle Life for Lower Lifetime Storage Cost
The improved temperature stability supports more than 8,000 deep charge and discharge cycles. This extends service life and increases total project return on investment over the system lifecycle.
Designed for Harsh Environmental Energy Storage Deployments
The container features IP55 system protection and IP65 battery pack protection. With C4 anti-corrosion capability, the system can operate reliably in high humidity, coastal salt environments, and extreme temperatures ranging from -30°C to +55°C.

Does the 5MWh battery container include PCS and transformer equipment?
No. This product is designed as a pure battery container. It does not include PCS or step-up transformer systems. This allows EPC contractors and project developers to select power conversion equipment based on specific grid requirements, voltage levels, and project design preferences. It offers greater flexibility for large utility-scale installations.
What type of projects typically use a 5MWh battery storage container?
This container is mainly used in large renewable energy storage projects, grid peak shaving, frequency regulation, shared energy storage stations, and independent utility-scale storage plants. It is especially suitable for projects that require high energy density and long operational lifespan.
How does liquid cooling improve battery performance and lifespan?
Liquid cooling maintains highly stable cell temperatures and minimizes temperature differences inside the battery clusters. This improves battery consistency, reduces thermal stress, and slows capacity degradation. As a result, the system supports more than 8,000 deep cycles and delivers stronger long-term performance compared with air-cooled battery storage systems.
Can the 5MWh container be expanded into larger storage systems?
Yes. The system supports modular expansion. Multiple battery containers can be connected in parallel to build energy storage systems ranging from tens of megawatt-hours to large utility-scale power stations. This allows projects to scale gradually based on investment and capacity planning.
Is the container suitable for harsh environmental conditions?
Yes. The container is built for demanding environments. It features IP55 system protection and IP65 battery pack protection, along with C4 anti-corrosion design. It can operate reliably in coastal areas, high humidity environments, and extreme temperatures ranging from -30°C to +55°C.
Commercial and Industrial Battery Energy Storage Systems (C&I BESS) are designed to help businesses manage energy more efficiently and maintain stable power supply. These systems store electricity and discharge it during peak demand or grid instability, providing fast, clean, and reliable energy support for daily operations.
Why Commercial & Industrial Energy Storage Matters
Battery energy storage enables peak shaving and load shifting, helping businesses reduce electricity costs and demand charges. It also delivers reliable backup power during outages, protecting critical equipment and minimizing downtime. When integrated with solar or other renewable sources, C&I BESS improves energy utilization and reduces dependence on diesel generators.
Due to higher power demand and system requirements, commercial and industrial energy storage is typically deployed in factories, logistics centers, EV charging hubs, commercial buildings, data centers, and solar-plus-storage projects where stable, scalable, and high-availability power is essential.
AnengJi provides scalable commercial and industrial battery energy storage solutions with flexible capacity configurations and seamless integration into existing energy systems. Designed for long-term reliability and easy deployment, our C&I BESS helps businesses lower operating costs, enhance energy resilience, and support sustainable growth.
