    We have cooperation with Murata as well as with many other Li-Ion cell producers, which has resulted in perfect understanding of battery cells and related technologies. We focus on the most efficient layout, low resistance of connections, intelligent electronics and BMS, connectivity, diagnostics, safety features and fire protections. We follow the latest production technologies, effectiveness and beneficial economic aspects.



    We lead you through the process of designing the complex electric propulsion system from the scratch. You don’t have to be an expert in field, just tell us your vision, the rest is our job.


    The team of 40 experienced electrical and mechanical engineers is always ready to face the toughest challenges. The are no limits for us, just the edge of the latest technology.


    We are not just integrators of the electric propulsion systems, we have the whole process of project finalization in hands thanks to our own product lines of the most important electronical components.


    It does not matter whether you have a project of electric airplane, e-VTOL, UAV/Drone, marine or automotive application. We have a very rich and detailed experience with the overall process of final implementation, including very thorough testing procedures.
