About Us

Founded in 2011 in Guangzhou, Seener Technology is a national high-tech enterprise specialized in the R&D, manufacturing, and custom solutions of lithium-ion batteries. We operate a 10000 m² facility with fully automated assembly lines, an R&D team of 20 engineers, and a daily production capacity of 2000 battery pack.

We focus on OEM/ODM services, offering a complete battery system solution—from industrial design and cell selection to BMS development and final assembly. Our product portfolio covers cylindrical Li-ion, Lithium Polymer, and LiFePO4 batteries, primarily serving clients in energy storage, light electric vehicles, and smart home devices across Europe, North America, and Southeast Asia.

Quality is our promise. Our products hold UL, IEC62133, CB, CE, ROHS, KC, and BIS approvals. Every single cell undergoes 100% capacity testing, internal resistance inspection, and aging screening before shipment, ensuring a delivery pass rate of 99.8%+.

What truly sets us apart is not our over 10 years in the industry, but our proven track record of supplying 30 clients with zero major quality incidents for over 5 years. We listen, we understand, and we deliver.
