What CSIP does

CSIP (Shenzhen CSIP Science & Technology Co., Ltd.) is a privately held Chinese manufacturer of custom lithium-ion battery solutions, headquartered in Longgang District, Shenzhen, with primary production operations at a 20,000+ square meter facility in Huizhou, Guangdong. The company was formally registered in 2018, though its founding team brings more than 20 years of cross-industry energy experience. CSIP specializes in two product families: custom pouch lithium polymer (LiPo) batteries in a wide range of capacities and form factors (including models such as CSIP401020 at 50 mAh, CSIP362030 at 170 mAh, CSIP353042 at 500 mAh, CSIP694060 at 2,000 mAh, CSIP184768 at 7,000 mAh, and higher-voltage packs such as UT-M27 at 14.4V 2,500 mAh), and standardized plus customized 18650 cylindrical lithium-ion cells. Manufacturing spans the full value chain in-house — electrode preparation, stacking/winding, electrolyte filling, formation, pack assembly, and BMS integration — supported by SMT lines and automated production equipment delivering 200,000–300,000 units per day.

The business is structured around a B2B, sales-led go-to-market targeting OEM manufacturers across consumer electronics, medical and professional devices, smart home and equipment, miniature AI robotics and drones, and small power tools. Pricing is quote-based with no public list pricing; sample lead times run 1–7 working days and mass production lead times 30–35 days after order confirmation. Distribution is entirely direct-to-OEM with global reach across Northern Europe, Southeast Asia, Eastern Europe, North America, Western Europe, and a domestic Chinese book, with logistics via DHL, UPS/FedEx/TNT, air, and sea. CSIP monetizes custom hardware sales plus OEM/ODM engineering services and bundled pre-sales consulting and after-sales support.

The customer base includes tier-1 OEMs such as Lenovo Group and Microsoft, and strategic partnerships validated by audits at LG Korea (July 2018) and Panasonic (June 2019). All products carry international certifications (UL, CE, KC, PSE, CB, RoHS, UN38.3, IEC62133-2, REACH) and the company operates under ISO9001, ISO14001, and ISO45001 management systems. CSIP is led by General Manager Han Yanqing, holds a Shenzhen Municipal Government 'Specialized and Sophisticated Enterprise' designation (2021), maintains a 30+ R&D engineer team focused on solid-state and fast-charging research, and discloses no external funding rounds — appearing to be founder-financed and operationally profitable.
