What WS Technicals does

WS Technicals A/S is a Denmark-headquartered designer and producer of custom lithium-ion battery packs for industrial OEM customers. Founded in 2015 as a spin-off from the intra-logistics sector, the company operates a hybrid model in which Danish engineers handle design, BMS integration, thermal management, testing, and certification, while production is executed through manufacturing partner HAIDI Energy at facilities in Zaozhuang and Dongguan, China, with combined capacity exceeding 250,000 battery packs annually across more than 40,000 m² of production space. The product portfolio spans low-voltage (24V–48V) modules for AGVs, AMRs, and forklifts; high-voltage systems reaching 750VDC and 275kWh for heavy machinery; fast-charge batteries for material handling; and highly specialized packs for UUVs/ROUVs, elevators, and electric motorcycles, all supported by proprietary in-house tools (AQUA end-of-line testing suite, FLOW shipment management system, WST-view firmware flashing software) and access to Lithium Balance BMS technology through a 2025 co-ownership stake.

The company's revenue model combines hardware sales of custom and modular battery packs with professional services for engineering development, certification (UN38.3, IEC, UL, CE, RoHS, ISO 26262, ISO 13849), and mass production. Pricing is quote-based with multi-year contracts, and distribution is exclusively direct to industrial OEMs — technical sales engineers engage customers from concept through production. Target segments include material handling and logistics (Noyes Technologies, FarmDroid), heavy equipment and machinery (Vario Drive, Linddana TP woodchippers), pest control (Anticimex), wind energy (Liftra), and specialized transportation. The company differentiates through engineering-driven customization, a 4-week rapid prototyping cycle, integrated quality control via AQUA and FLOW, and the cost arbitrage of Chinese manufacturing sold into European OEM accounts. As of the available data, WS Technicals has not raised institutional venture or private equity capital and remains privately held under founder-CEO Louis B. Danielsen.
