What we do
POWERING FLIGHT, BY DESIGN
POWERING FLIGHT, BY DESIGN
POWERING FLIGHT, BY DESIGN
EagleBAT is developing a fully integrated airborne battery system, engineered from a clean sheet from the cell chemistry all the way to the complete system. Purpose-built for aviation, not adapted from off-the-shelf automotive batteries.

Performance
Lightweight, high-capacity battery systems built specifically for aviation. Our integrated design extends operational range without adding weight, giving aircraft the energy they need to fly further and longer.
Safety
Intelligent battery management protects every cell across the entire life cycle. From smart monitoring to robust system architecture, EagleBAT delivers the high safety level that electric aviation demands.
Circularity
We designed to dismantle, repair, and reuse at every level. From easy upgrades to the recovery of scarce materials at cell level, every battery is built to extend its life, reduce waste, and stay future-proof.
