Since 2008, we have become Europe's largest distributor of LFP cells. In 2021, we also established our own ELERIX battery cell brand and a division dedicated to the development and implementation of complete home and industrial energy storage systems under the AMVOLT brand.


Over the course of our existence, we have helped thousands of customers around the world design complete battery storage solutions of all sizes. As a result, we have amassed a completely unique know-how that you will hardly find elsewhere in Europe.

All products in the portfolio (including solar panels and other energy components such as inverters, battery management solutions, chargers or charging stations, etc.) are thoroughly tested and selected from proven manufacturers directly by the GWL Group's technical department. This ensures that only the highest quality products make it into our portfolio.


Our strategic advantage is an average stock of 12 MWh of the highest quality LFP cells available in our Prague warehouse. This has led us to create the AMVOLT brand - a European manufacturer of complete battery systems of all sizes.

We continue to use the same strategic advantage to develop and design replicable battery solutions for customers with self-storage needs.

The range of our customers' focus is truly broad: from freight locomotives and industrial equipment to ships, transmitters, robots, lawn mowers, as well as coffee machines and more.



That's how we started in 2006 - GWL founders Michal Klečka and Jan Sedlák DIY-ed an old Golf into an electric car capable of driving 250 km on a single charge. They chose LFP cell technology (LiFePO4).

Thanks to their unrivalled durability, performance, recyclability and above all safety, these cells have become the imaginary king of battery technology worldwide and GWL Group has been there from the very beginning.
