Q: Are you a manufacturer or a trading company?
A: Shenzhen NU Energy Technology Co., Ltd. is a comprehensive new energy enterprise integrating R&D, production, and sales. Founded in 2016 by a senior technical team with early involvement in China's lithium-ion battery R&D, we handle the entire process from research and development to manufacturing and final sales. We also have several affiliated companies, such as Jiangxi NU Energy Technology Co., Ltd. and Jiangxi Chengjiang New Energy Co., Ltd., which further support our manufacturing and supply chain capabilities across materials, cells, and recycling.
Q: What types of lithium-ion battery cells can you supply, and do you offer customization?
A: We offer a wide range of cylindrical lithium-ion battery cells based on various chemistries, including Lithium Iron Phosphate (LFP, LiFePO4), Nickel Cobalt Manganese (NCM), and Lithium Manganese Iron Phosphate (LMFP). Our product portfolio covers popular sizes like 18650, 21700, and 32700, with diverse options in capacity (e.g., 1500mAh up to 6000mAh+) and discharge rates (from standard 0.5C up to 5C high discharge). Leveraging our strong R&D capabilities and close cooperation with universities, we absolutely welcome and specialize in providing customized battery cell solutions tailored to meet your specific application requirements.
Q: How do you ensure the quality and reliability of your battery cells?
A: Quality is paramount at NU Energy. We maintain strict quality control throughout our R&D and production processes. Our founding team possesses over 20 years of experience in the new energy battery field, ensuring deep technical expertise. We adhere to an innovation-driven philosophy, hold independent intellectual property rights for our products, and collaborate closely with leading universities like Sun Yat-sen University for ongoing research and development. While specific certifications should be confirmed upon inquiry, our commitment to robust R&D, experienced personnel, and integrated processes ensures high-quality and reliable battery cells.
Q: What is your Minimum Order Quantity (MOQ) and typical lead time?
A: Our Minimum Order Quantity (MOQ) and lead times can vary depending on the specific battery cell model, order volume, and customization requirements. We strive to be flexible and accommodate our clients' needs. For detailed information regarding the MOQ and estimated lead time for the specific products you are interested in, please contact our sales team directly with your requirements. We will provide you with a specific quotation and timeline promptly.
