Battery systems for the next generation of energy.

High-performance, modular battery systems engineered for demanding applications built from new or second-life EV cells.

Power where performance matters most

Battery systems designed for mobility, industrial and energy storage applications.

Energy systems are no longer defined by capacity alone. They are defined by reliability, integration and adaptability.

EION battery systems are designed for high-demand applications, with modular architecture and consistent long-term performance.

Designed and assembled in Barcelona, Engineered to Change the World.

Performance requirements are increasing. Lifecycles are getting shorter. And disposable batteries are no longer viable.

EION exists to change that. We design modular battery systems built for longevity, adaptability and real-world performance.

No greenwashing. Just engineering.

Battery systems designed for flexible configuration across voltage, capacity and application requirements.

From 0,5 kWh to 50kWh systems, same architecture, high performance.

Multi-layer protection systems including advanced BMS, thermal management and fault isolation systems.

Tested, graded and integrated EV cells with 70-80% remaining capacity, repurposed into reliable energy systems.

Technology

Every component is designed to connect, communicate and scale as a unified system.

Battery modules, chargers and inverters built on a single, integrated architecture.
