Our mission : to make high performance batteries affordable for your application.

Our patented immersion cooling technology enables to push the boundaries of classical lithium-ion batteries, by increasing their performance, life and safety.

We are delivering heavy duty mobile applications like equipment in construction, agriculture, mining but also special road vehicles (trucks, municipal vehicles) or high performance vehicles, like racecars.



Our products are certified according to ISO 26262 and IEC 62619.



Our energy and our know-how to serve our industrial partners and our society

With a 45 years cumulated experience in design, manufacturing and use of batteries, in mechanical, electrical and electronical systems, the four partners of WATTALPS form a very complementary team.



They also gather the cultures of three countries at the boarder of the Alps (France, Germany and Italy). They maintain a “crew” spirit to get the best of their competences and energies. The “ALPS” particle in the brand name WATTALPS refers to the mountaineering roots, symbol of will, commitment and solidarity to come through the hardest challenges.



The objective is to build a cleaner industry with a great respect of citizen needs (pollution, noise). It is embodied by strong commitments like recycling 100% of the lithium batteries sold by the company.
