About Wiren

Battery Engineering with Integrity

Wiren Shenzhen Co., Ltd. provides lithium battery and energy storage solutions for residential, commercial, marine and motive power applications. Based in Shenzhen, we work with OEMs, distributors, integrators and project teams to connect application requirements with practical battery configurations.

Wiren Shenzhen Co., Ltd. and Wiren Romania SRL are affiliated companies within the same corporate group.

Our approach starts with how the battery will be used: the load, environment, installation space, charging method and system interfaces. From product selection to OEM/ODM discussions, clear specifications help turn a market need into a defined project.

Our range includes U5 5.12kWh server rack batteries, Sentinel golf cart batteries and commercial energy storage solutions.

Battery Quality and Supplier Evaluation

When evaluating a lithium battery manufacturer or supplier, request the current model specification, relevant test documents, inspection requirements and warranty terms for the proposed configuration. Contact Wiren to discuss the documentation needed for your project.

Our Philosophy

Energy When and Where It Matters

As mayflies we abide in the cosmos; as a grain of millet we float in the great sea.

This perspective reminds us to act with purpose and integrity. Energy is not always available at the time or place it is needed. Batteries help us store electricity for later use and bring power to more applications.

For Wiren, meaningful progress begins with real needs, thoughtful engineering and honest communication. Our mission is to be an authentic energy infrastructure provider.

  • Mission Statement

    To be an authentic energy infrastructure provider.

  • Core Values

    Authenticity. Stability. Simplicity

  • Slogan

    In a world of change, integrity endures.

    Authenticity

    Clear and Honest Communication

    Trust begins with an accurate description of what a product can do. We aim to make requirements, model specifications and project responsibilities clear, including the limits that matter for the application.

    Authenticity means discussing questions openly and making commitments that can be understood and followed through.

    Profession

    Engineering Around the Application

    Battery selection involves more than voltage and capacity. Load profiles, current demand, temperature, charging and communication all influence the configuration.

    Our engineering discussions bring these requirements together so the product and its interfaces can be reviewed as part of a complete application. Learn about our battery engineering approach.

    Market Focus

    A Practical OEM/ODM Brief

    Different markets and operating environments call for different battery requirements. We work from the needs of the equipment and the people using it, including installation space, connectors, charging and product presentation.

    A clear brief provides the basis for discussing configuration, branding and supporting documentation. Explore our OEM/ODM project support.

    Competitive Edge

    Value Across the Product Lifecycle

    Purchase price is one part of a battery decision. Suitability, installation, maintenance and access to the right technical information also deserve attention.

    We focus project discussions on these practical considerations, with Stability and Simplicity guiding the approach. In a world of change, integrity endures.
