We optimize the production phases and fulfill the manufacturing process requirements.

We know that our expertise and our production equipment are decisive factors when it comes to manufacturing your products. That is why we adapt to your expectations to meet your objectives in terms of flexibility and quality at the best cost, all while guaranteeing you reliable and long-lasting products.

Lean manufacturing at the heart of our industrial processes

We mass produce lithium batteries in France with the guarantee of secure industrial processes.

The lean approach is at the heart of our industrial processes and our continuous improvement approach. We improve and optimize flows to reduce cycle times and improve quality.

Our production combines automated and manual processes to guarantee flexibility and the best cost/quality ratio according to your volumes.

All our batteries are 100% traced and checked at the end of the line, allowing us to ensure the best quality indicators.

Key flexibility advantages

Thanks to the flexible configuration of our manufacturing lines, we can modify our workshop setup within 24 hours, which allows us to double production to meet your current or future timing requirements and deliver within the deadlines we defined together. In addition to this flexible structure, we benefit from an employment pool rich in battery expertise that allows us to quickly ramp up thanks to the many qualified and available employees in the area.


Expert manufacturer of lithium-ion battery systems

Agility and rapid prototyping

We have a very large library of battery references resulting from the work of our Research & Development laboratory. Our years of experience allow us to advise and support you so that you can move more quickly from design to prototyping, saving precious time for experimenting with prototypes in your applications.

A unique approach to sustainability

Faced with the growth of the battery markets, and especially with a mind toward companies that lease urban two- to four-wheel vehicles, we have opted for a #DesignForRepair approach to facilitate the repair of batteries. Our designs incorporate aspects that facilitate disassembly, allowing access to all the components and simplifying reconditioning. Our industrialized repair process includes test and diagnostic benches dedicated to these operations. Indeed, the batteries from fleets are subjected to high-stress conditions and are often mechanically damaged. In order to make it easier to repair and change them, it is necessary to engineer them with a specific design to facilitate their refurbishment. The aim of this approach is to avoid systematically recycling systems that could be repaired.

Maximum safety thanks to our 360DesignControl process

Battery safety is a major issue for all manufacturers.

Considering the spacing of the components and designing a safe mechanical architecture integrating thermal constraints and mechanical resistances are reliability guarantees that new manufacturers sometimes neglect.

Our 20 years of experience and the rigor of our 360DesignControl process allow us to also integrate high-performance electronic development, enabling us to adapt the BMS to the electrochemical components, including redundant systems. The safety of your batteries is an absolute priority for our teams.
