DEVELOPMENT
Thanks to our in-house design office, we develop our own technological solutions. This internal expertise allows us to control the deadlines, quality and security of our systems while offering our customers competitive and high-performance solutions.

Based on your specifications, we design, develop and produce your battery from prototype to series production!
Our experts support you throughout your project:
Our available and competent teams support each customer with efficiency and commitment. The in-house integration of all stages, from design to production, ensures complete and consistent control of the projects entrusted to us.

Our goal? To design and develop a solution perfectly suited to your application, working with you to define the trials, tests and certifications applicable to your product and necessary for its market launch.
Thanks to our expertise and technical resources, we carry out these validations in-house and/or in partnership with approved external laboratories to guarantee the reliability and regulatory compliance of our products to the most demanding standards. We incorporate all new safety standards, certifications and approvals into our approach.

At GCK Battery, we design and develop our own BMS (Battery Management System) and control systems in-house. This expertise is crucial for mastering all aspects of lithium-ion battery technology, ensuring their proper functioning and safety.
We design and develop our own electronic management systems:
We also offer quick and easy adaptation of our BMS to meet customer needs.
The electronic boards are produced in-house on our CMS line, which allows us to control costs, monitor our supply chain and enhance security.
At each stage of the project, we test our products to ensure they meet the specifications requested by each of our customers, providing them with a reliable and durable product. To do this, we have a range of testing tools and test benches at our disposal.





Because a unique product requires unique industrial tools, we go far beyond conventional testing.
Our teams design customised test benches in-house, perfectly adapted to the specificities of each product and the requirements of our customers, guaranteeing performance and compliance at every stage.
Why does this make a difference?
Designing custom batteries also means thinking about their entire ecosystem. At GCK Battery, we control every stage to meet our customers’ most specific requirements.
Production
Our production facilitiesWe offer Made in France manufacturing in our workshops with a production capacity of 140,000 batteries per year, an automated production line and three automatic welding machines. Our production and assembly facility, located in the heart of Auvergne, allows us to be as close as possible to your needs for optimal quality and responsiveness.

Our new automated line is dedicated to the production of core packs, sub-assemblies that make up our battery packs.

GCK Battery is a French manufacturer based in the heart of Auvergne. Our 100% local production allows us to remain close to our customers and provide personalised support throughout the life cycle of our products.
The main components of our products are manufactured by GCK EMI, another subsidiary of the GCK group: BMS and power electronics, harnesses and cables, casings, cell holders, tags, etc. This collaboration enables the vertical integration of components manufactured locally in our workshops in Brassac-les-Mines (63). Our production lines are also located on the same site in order to be as close as possible to our main supplier and to optimise the industrialisation of our batteries.
Our site in Lempdes (63) is dedicated to the design and production of customised prototypes for very specific projects.
Thanks to this proximity, we guarantee responsive follow-up, high-quality after-sales service and maintenance of the most specific batteries, provided by our teams of experts.
