GCK Battery, based in Lempdes, France, is a specialist in designing, developing, and manufacturing lithium-ion battery solutions for diverse applications in professional and consumer markets. Founded in 2019 as part of the GCK Group’s Technology Division, the company emphasizes end-to-end innovation, from conceptualization through mass production. Its product portfolio includes standard, modular, and custom battery systems, ranging from lightweight batteries under 500 grams to heavy-duty battery packs exceeding 4 tonnes.
Key markets served include e-mobility (electric vehicles, scooters, and rail transport), industrial automation, energy storage, and motorsports. A hallmark of GCK’s approach is its in-house design bureau and advanced testing infrastructure, ensuring rigorous validation and certification processes. Notable collaborations, such as its partnership with Motul to develop ultra-fast-charging immersed battery technology, underscore its focus on advancing battery performance and safety. With a vertically integrated production facility in France, GCK provides tailored solutions to support decarbonization across sectors like transportation, energy, and heavy industry.
Battery Technology
GCK Battery’s core offerings include standard 48V lithium-ion batteries (with 24V models in development), modular systems built from scalable subunits, and fully custom designs configured to meet precise voltage requirements between 3.6V and 1000V. The company’s proprietary immersed battery technology, co-developed with Motul, represents a significant innovation. This system submerges battery modules in a dielectric fluid, enabling ultra-fast charging (under 10 minutes) while enhancing thermal stability and reducing risks of thermal runaway. A key enabler is GCK’s in-house Battery Management System (BMS), which optimizes cell performance, extends cycle life, and ensures safe operation across varied conditions.
Manufacturing takes place at a 2,500 m2 facility in Lempdes that has automated welding systems and a dedicated SMT line for electronics production. This setup supports both high-volume production (targeting 140,000 units annually) and prototyping for specialized projects, such as heavy-vehicle retrofit solutions. Applications range from electric scooters and industrial robotics to grid-scale energy storage, with hybrid-integration expertise applied in projects combining lithium-ion and hydrogen fuel cell systems.
Recent Projects
Recent milestones include supplying a 48V immersed battery system to the APH-01 T3-U hybrid vehicle, which competed in the 2024 Africa Eco Race, demonstrating the technology’s real-world feasibility in demanding motorsport conditions. GCK also collaborated on the e-Blast H2 initiative, integrating its batteries with hydrogen fuel cells to power a rally-raid race vehicle. Additionally, the company advanced efforts to retrofit traditional waste collection trucks with zero-emission electric systems, reflecting its commitment to decarbonizing heavy transport. These projects build on the 2022 inauguration of its expanded facility, designed to streamline heavy-vehicle battery production and fast-charging R&D.
Investors
GCK Battery has secured approximately $14.43 million in funding through strategic partnerships and investment. Prominent collaborators include Motul as a technology partner. Financial backers include AMINVEST (operated by Amaury Mulliez), which invested in March 2023, and Shift4Good, which joined in September 2024. Regional banking institutions such as Crédit Agricole Centre France and Banque Populaire Aura provide additional financial support, bolstering GCK’s capacity to scale manufacturing and advance innovations like immersed battery systems.
