Unlike standardized products, ONESUN's customization services go beyond simply "OEM manufacturing." They involve the entire process from concept design, prototype testing, intelligent BMS configuration, overall package optimization, to mass production delivery. Customers can submit customized requirements based on their specific application scenarios—such as electric vehicle power batteries, energy storage systems, and industrial power supplies—and the technical team will provide the most cost-effective and competitive solutions.

III. Leading Battery Management System (BMS) and Safety Assurance

In high-voltage battery systems, safety and stability are core indicators of battery quality. ONESUN possesses a self-developed intelligent BMS that can monitor key parameters of the battery pack in real time, such as voltage, temperature, and state of charge (SOC), and provides multiple protection measures including overcharge, over-discharge, short circuit, and high-temperature protection to ensure stable operation of the battery pack under extreme environments and complex load conditions.

Furthermore, the company uses Grade A LiFePO₄ cells from leading industry brands as the core energy unit. These cells are known for their high safety, long cycle life, and stable performance, effectively extending the overall system life and improving operational reliability.

IV. Global Service and Customer Support System

ONESUN understands that in global market competition, product quality is only the foundation; comprehensive pre-sales, sales, and after-sales service is the key to the company's sustainable development. Whether it's customer inquiries, technical support, overseas logistics, or after-sales support, ONESUN has established an efficient response mechanism to ensure that global customers can quickly obtain the necessary technical information and application solutions, truly achieving seamless integration of products and services.
