Unlock untapped potential of your battery

Increasing battery life

Early results in refurbished batteries show +100% increase in battery life. With continuous load balancing FABBS reduces spread significantly improving performance of the whole battery over its full lifetime.

More usable capacity

Continuous balancing unlocks 20% more capacity that was otherwise lost.

Pushing your battery to its absolute physical limits

This is how we do it

Access at the cell-level

FABBS incorporates smart circuitry to have direct acces to each individual cell inside the battery. This allows us to have full control and in-depth insight into every corner of your battery.

Excite internal cell dynamics

Our proprietary measurements excite key dynamics within the cell. Looking at how the cell responds we gain a physical understanding of its insides.

Efficient interpretation of data

Using the measurements our proprietary modeling approach efficiently creates models of each cell in real-time.

Management based on internal state

This physics-based insight is used to control the cells and push each one to its absolute physical limits.

Meet

team FABBS

FABBS was founded in March 2025 by a group of students, united by a shared ambition to contribute to the energy transition. Through hands-on projects in electric mobility and energy systems, we noticed that there is still much to gain in today’s battery usage—and how rethinking battery management could make a meaningful difference.

Guided by that insight, FABBS was launched with the mission to enable longer-lasting, more efficient use of batteries and to support a circular energy system. We strive to challenge established norms and bring fresh perspectives to the way energy is stored and used—building a company that transforms bold ideas into real-world impact.

Join the FABBS team

We develop the most advanced Battery Management System in the industry. At FABBS, a young and ambitious team in Eindhoven, we turn complex battery physics into smart, practical control. Every line of code, circuit, and model we build pushes the boundaries of what batteries can do. We move fast, make decisions quickly, and everyone contributes directly to something that matters. No layers of management, no endless meetings, just real engineering and teamwork. apply now!
