What EWT Battery does
Dongguan Everwin Tech Co., Limited (operating as EWT Battery) is a privately held Chinese battery manufacturer founded in 2005 and headquartered in Shenzhen, with production operations in Dongguan, Guangdong. The company designs, manufactures, and exports a broad portfolio of battery cells and packs across six chemistries: lithium iron phosphate (LiFePO4), lithium ion, lithium polymer, lithium thionyl chloride (Li-SOCl2), nickel metal hydride (NiMH), and nickel cadmium (NiCd). Voltage configurations span 3.6V primary cells to 51.2V high-voltage systems, with capacities up to 400Ah and Energy Storage System (ESS) solutions from 5 kWh to 20 kWh for residential and commercial applications. Integrated Battery Management System (BMS) features include Bluetooth monitoring and RS232 communication.
The company serves B2B customers across four primary verticals: electric mobility (golf carts, e-bikes, scooters, forklifts, wheelchairs, marine), energy storage (residential solar, off-grid, telecom backup, UPS), industrial electronics (utility meters, security systems, medical devices, IoT/remote monitoring), and consumer electronics (power tools, toys, wireless vacuums). Customer engagement flows primarily through a multi-language corporate website (available in 20+ languages including English, German, French, Spanish, Portuguese, Russian, Japanese, Korean, and others), direct sales contact, and selective trade show participation such as Electronica Munich.
The revenue model combines three streams: one-time sales of branded battery products, OEM/ODM custom-pack design and manufacturing services, and complete energy storage system hardware sales. Pricing is quote-based with low MOQs (e.g., 10 pieces) on standardized products and transactional terms including L/C, T/T, and Escrow. Shipping is offered on FOB, CIF, and CNF incoterms globally. Quality assurance is asserted via 100% full-load aging tests and 1-3 year warranties. No external funding rounds, named institutional investors, patents, certifications, or disclosed revenue figures were present in the available source data.
