In the rapidly evolving new energy industry, production line efficiency and stability have become crucial indicators of a company’s core competitiveness. Recently, Chinese company ONESUN announced exciting news: its newly developed semi-automated battery assembly line, co-created with equipment partners, has officially gone into operation today after two months of swift installation and repeated debugging. This marks not only another breakthrough for ONESUN on the road toward intelligent manufacturing but also a leap forward in its delivery capabilities.
What makes this production line stand out?
First, its production capacity is remarkable. The new process has significantly boosted assembly efficiency, enabling the stable completion of around 3,600 cells per day. At full capacity, the line can assemble 200–300 battery packs daily. Such performance not only ensures the rapid fulfillment of existing orders but also provides a solid foundation for handling large-scale customer projects.
Second, the semi-automated mode brings unique advantages in both precision and flexibility. Unlike traditional manual lines, this production line automates critical stages of the process, reducing human error while greatly shortening cycle time in mass production. In addition, the line’s design incorporates flexible interfaces, allowing quick adjustments to meet diverse customer requirements while maintaining high efficiency.
For customers, this is undoubtedly a strong reassurance. With energy storage demand surging and market competition intensifying, what customers value most is on-time delivery and stable quality. The launch of ONESUN’s new line directly addresses these pain points—it delivers faster and with greater consistency. Rapid shipping ensures projects are completed as planned, while high-quality output lowers after-sales and maintenance costs. This dual guarantee further reinforces ONESUN’s brand reputation for its “long lifespan, easy maintenance” technology.

It is worth noting that the entire project—from planning to full operation—took only two months, thanks to ONESUN’s highly efficient collaboration with its partners. From equipment selection and layout design to installation, commissioning, and trial optimization, the team demonstrated seamless coordination and strong execution. This not only highlights ONESUN’s management efficiency but also reflects the company’s ability to quickly respond to evolving market needs.
Looking ahead, ONESUN will continue to strengthen intelligent manufacturing, steadily advancing the digitalization and automation of its production lines. With the introduction of more advanced processes and equipment, the company plans to expand high-efficiency capacity globally, further enhancing its ability to serve customers worldwide.
As one industry expert put it: “ONESUN’s new production line is not just about capacity expansion—it represents a professional capability upgrade, giving the company a stronger edge in fierce competition.” Clearly, the commissioning of this semi-automated line will open up broader market opportunities for ONESUN.
In the race of the new energy sector and solar power station, speed and quality are equally essential. ONESUN is proving, through concrete actions, its commitment to being “fast, reliable, and trustworthy.”
Note: Overseas partners who wish to assemble lithium batteries locally, China OneSun can also handle manual and semi-auto production lines sales, provide local installation, user training, and other related product services.
