What wattalps does
WATTALPS is a French designer and manufacturer of lithium-ion battery systems founded in 2018 and headquartered in Moirans, France. The company targets heavy-duty and off-road industrial equipment manufacturers across construction and mining, maritime, commercial vehicles, cargo handling, agriculture and forestry, and stationary battery energy storage (BESS). Its core technology is a proprietary immersion-cooling architecture for lithium-ion cells, protected by 7 patents, which differs from conventional air or liquid cold-plate thermal management by submerging cells in a dielectric coolant for more uniform temperature control, higher power density, and improved safety. The product portfolio includes modular battery packs ranging across traction, high-power, and stationary applications, paired with a Battery Management System (BMS) supporting OTA updates and engineered to ISO 26262 functional safety standards.
The company's business model is direct enterprise and OEM sales with a consulting-style sales cycle: battery packs are custom-engineered into each customer's platform (skid-steers, port equipment, hydrogen trucks, micro-mobility vehicles, etc.) and sold as integrated, homologated subsystems rather than as off-the-shelf SKUs. WATTALPS has secured customers including Vermeer, Hyliko, Telma, Ligier, Eaton, Aeonpump, Vahle, and an unnamed major port operator, spanning both OEMs and end-user operators. Revenue mechanics combine per-pack hardware sales with the embedded value of homologation documentation and engineering services. The company has signaled a target of €100 million in revenue within five years and is scaling production capacity roughly eight-fold toward 400 MWh/year, financed by an €11 million Series A closed in August 2024.
Strategically, WATTALPS has accumulated a series of certifications and partnerships that define its market access: a world-first UN R100 Rev. 5 Type Approval from Germany's KBA, a Bureau Veritas Marine Type Approval (January 2026), and a research and commercial partnership with CEA-Liten and Codelco targeting the mining sector. Geographic expansion into North America and Southeast Asia is planned. The customer base is concentrated in European industrial OEMs, with reported 89% customer satisfaction supporting a reference-driven growth motion. The company operates with a headcount in the 11–50 range, consistent with early-commercial scale, and the input evidence does not indicate AI/ML capability beyond BMS-level embedded software.
