Topu Technology manufactures high energy-density lithium and solid-state battery cells, primarily for drones, with extensions to e-motorcycles and robots.
Foshan Topu Technology Co., Ltd. (陀普科技), trading as TOP Technology, is a Chinese battery manufacturer founded in 2019 and based in Shunde District, Foshan, Guangdong. The company develops high energy-density lithium and solid-state battery cells using lithium-rich manganese-based cathodes, silicon-carbon anodes and solid-state/composite electrolytes, vertically integrating cell R&D and production, battery management systems (BMS) and pack system integration.
Its primary commercial product is a line of drone batteries reaching 400-460 Wh/kg energy density, which it has shipped in volume for about two years and says is profitable. It has since extended its cell technology to high-rate batteries for electric motorcycles (320 Wh/kg, supporting sustained 8C/instantaneous 12C discharge), and markets cells for humanoid and legged robots, electric vehicles, power banks, and modular commercial/residential energy storage systems (50-300 kWh).
In November 2026 the company disclosed a Series A funding round of roughly $4.5 million from Huaibei Jishan, Anhui Hengna and Chongqing Haite, earmarked for building a 0.5 GWh production base in Huaibei, Anhui, targeted to begin production in January 2027. The company was founded by Chen Guangsen, who previously worked on battery R&D at Varta in Germany.
