Meeting the Rising Global Demand for Commercial Energy Storage

In 2024, the global demand for commercial and industrial (C&I) energy storage has experienced explosive growth, becoming one of the most dynamic segments of the energy storage industry. According to data from the China Chemical and Physical Power Industry Association’s Energy Storage Application Branch, in the first half of 2025 alone, China’s newly installed C&I energy storage systems reached 1.4GW/3.4GWh, representing a year-on-year increase of 66.10% and 58.39% respectively.

The scope of C&I energy storage has expanded far beyond simple peak-valley electricity arbitrage. Today, enterprises are leveraging storage systems for emergency backup, energy efficiency improvements, carbon reduction, and electricity cost optimization. This growing demand is driving innovation across the industry, with safety, efficiency, and intelligent management emerging as key focus areas.

Introducing the ENDURO S+: A New Era of Smart Energy Storage

To address these evolving market needs, BAK Battery has launched the ENDURO S+ Commercial and Industrial Liquid-Cooled All-in-One Energy Storage System. This cutting-edge solution features BAK’s self-developed 314Ah high-capacity cell, offering:

• 10,000 charge-discharge cycles for extended operational life

• 190Wh/kg energy density for compact yet powerful performance

• 2P high power configuration with over 95% discharge efficiency

• Comprehensive safety assurance, verified through nail penetration tests

These innovations make the ENDURO S+ one of the most reliable and high-performance commercial storage systems available today.

Compact Design with Exceptional Energy Density

The ENDURO S+ system adopts a highly integrated modular design, ensuring both flexibility and space efficiency. The system achieves over 92% overall discharge efficiency and offers a cabinet capacity of 261kWh, occupying only 1.3 square meters of floor space—approximately 27% smaller than traditional double-door cabinets.

Furthermore, the ENDURO S+ supports flexible expansion and multi-unit parallel operation, allowing up to ten systems to operate in parallel. This adaptability makes it ideal for industrial parks, shopping malls, office buildings, and EV charging stations, meeting diverse application needs with ease.

Built-In Safety and Smart Monitoring

When it comes to energy storage, safety is non-negotiable. The ENDURO S+ integrates multi-layered fire protection, intelligent monitoring, and 24/7 remote supervision. It provides multi-level protection at both the Pack and compartment levels, effectively preventing risks and ensuring stable long-term operation.

This robust safety design, combined with advanced real-time data analytics, enables operators to detect anomalies early, optimize performance, and minimize downtime—crucial for mission-critical facilities.

Dual Functionality: Backup Power and Cost Optimization

The ENDURO S+ is designed for both grid-connected and off-grid operation, ensuring uninterrupted power supply for key equipment during outages or grid fluctuations. Beyond backup functionality, the system enhances energy efficiency through peak shaving, valley filling, and demand-side management, helping enterprises reduce long-term electricity expenses.

With a lifespan of up to 15 years and a return on investment (ROI) period of just 3 to 4 years, the ENDURO S+ delivers significant cost savings while contributing to sustainability goals.

Driving Green Growth Through Innovation

The launch of the ENDURO S+ reinforces BAK Battery’s leadership in the energy storage sector, highlighting its strong capabilities in battery technology, system integration, and smart management. This product marks a major step forward in offering safe, efficient, and scalable energy storage solutions tailored to modern commercial and industrial needs.

Looking ahead, BAK Battery will continue to deepen its commitment to energy storage innovation, expand its application scenarios, and respond to evolving market demands. By doing so, it aims to inject new green momentum into the global push for sustainable, high-quality industrial development.
