Custom Lithium Battery Solutions Manufacturer | ONESUN Global OEM & ODM

In the global wave towards sustainable energy and smart power applications, custom lithium battery solutions have become a core requirement for new energy systems. As a highly recognized international brand battery manufacturer, ONESUN leverages its deep technological foundation and keen market insight to provide global customers with comprehensive custom battery solutions covering residential, commercial, industrial, and even specialized fields, helping them address diverse power challenges.

Since its founding in 2014, ONESUN has established "quality and safety as the lifeline of the company" as its core value. The brand has not only accumulated rich experience in photovoltaic energy storage, hybrid power systems, and mobile energy systems, but has also established a vertically integrated R&D and manufacturing system encompassing battery cells, BMS (Battery Management System), inverters, and system integration. This vertical integration model gives it a significant lead over its competitors in customization capabilities.

In practical applications, customer needs for power systems vary widely: from lightweight outdoor equipment power supplies to high-power industrial energy storage, and systems with special shapes or high voltage requirements, standard products often cannot fully meet these needs. Leveraging its advanced engineering team and flexible manufacturing capabilities, ONESUN offers fully customized lithium-ion battery pack solutions. These solutions support adjustments to voltage, capacity, casing structure, communication protocols, and even branding to meet specific customer needs, tailoring the most suitable power core for various projects worldwide.

This extends beyond the design level to the entire production and delivery process. ONESUN boasts multiple intelligent production lines and a rigorous quality control system, ensuring industry-leading safety, durability, and performance at every step, from cell selection and BMS programming to pack assembly and system testing. The application of lithium iron phosphate (LiFePO₄) materials, in particular, provides significant advantages in safety, thermal stability, and cycle life, making it ideal for equipment requiring frequent start-stop cycles, long operating times, or operation in harsh environments.

ONESUN's customized solutions also excel in solar energy storage projects, off-grid systems, or hybrid power systems. Customers can choose a modular design based on installation space, power requirements, and even future expansion plans. This allows battery packs to be freely combined like building blocks, meeting current needs while leaving ample room for future upgrades. Simultaneously, an advanced BMS enables real-time monitoring and intelligent management, ensuring long-term stable system operation.

In fact, ONESUN's customers span over 70 countries and regions worldwide, and its customized battery solutions are widely used in various scenarios such as residential energy storage, commercial backup power, industrial peak shaving, base station communication, and emergency power. Whether it's wall-mounted batteries in residential photovoltaic energy storage systems or high-voltage battery packs in large industrial energy storage cabinets, ONESUN can quickly respond to customer needs with professional customized services, fulfilling its promise of "not just selling products, but designing power solutions."

In this era of continuous energy transformation and upgrading, ONESUN, with its strong customized R&D capabilities, global vision, and stringent quality control system, is becoming a trusted battery solution partner for users worldwide. Whether you are a residential user needing to improve energy self-sufficiency or an industrial customer requiring stable power supply, ONESUN can tailor the most suitable, reliable, and cost-effective lithium battery customized solution for you.
