Grepow is a Shenzhen battery manufacturer selling named lithium cells engineered specifically for humanoid, combat, and underwater robot power systems.
Shenzhen Grepow Battery Co., Ltd. (brand name Grepow) is a lithium battery manufacturer founded in 1998 and headquartered in Shenzhen, China, with additional operations in Hunan and Zhejiang provinces plus overseas offices in Germany and the United States. The company's website states it employs more than 3,500 people, including a research and development team of over 300 engineers, and that it operates its own testing laboratories. Grepow lists ISO 9001, ISO 14001, OHSAS 18001, ISO 45001, IATF 16949, and ISO 13485 certifications, and states its products carry GB, CE, UN, and UL marks.
Grepow's core products are battery cells across several chemistries: lithium polymer, lithium iron phosphate, nickel-metal hydride, button cells, shaped and custom-form cells, semi-solid-state cells, and high-discharge-rate cells. Applications listed on the company's site include unmanned aerial vehicles, RC hobby equipment, wearable devices, medical devices, and industrial equipment. The site also has a dedicated 'Custom' section describing made-to-order battery design and manufacturing services for OEM customers, which is the basis for classifying Grepow's trade role as a custom battery manufacturer rather than a pure catalog seller.
Grepow maintains a dedicated robotics solutions section on its website with sub-pages for humanoid robots, combat robots, bionic robots, mobile robots, AI companion robots, and underwater (AUV) robots. Its humanoid robot battery page lists specific cell models with published specifications: the GRPB048102, a semi-solid-state NMC811 pouch cell rated at 9,300mAh and 4.2V with a 5C discharge rate, weighing 117 grams, part of a family the company says reaches 290-320 Wh/kg energy density; and the GRP4468088, a high-discharge-rate cell rated at 2,000mAh and 4.35V with a 40C discharge rate, weighing 47 grams and measuring 4.2 by 67 by 87.5 millimeters. The same page also lists fast-charge cells such as the GRP6548078, rated at 3,400mAh and 4.4V with a 5C charge rate. These published, model-specific specifications indicate Grepow is actively engineering battery cells for humanoid robot power systems, distinct from its broader consumer and industrial battery catalog.
Grepow's contact channels include a China phone line and a Chinese-market email address, alongside separate United States and German contact numbers for its regional offices. No public funding history or stock listing information was found for the company, consistent with it operating as a privately held manufacturer.
