Salon du Bourget édition 2025
For the first time, Williamson Electronique took part in the Paris Air Show at Le Bourget, held from June 15 to 21, 2025. At a booth brought to life with full-scale prototypes, we showcased our high-density Li-ion batteries for drones and emergency beacons, as well as our intelligent management module (BMS), attracting an audience of decision-makers and engineers. This presence led to the establishment of over a dozen new contacts with innovative SMEs, paving the way for upcoming pilot projects and collaborations.
