Megawatt charging at every gate
Concept visualization — the airport infrastructure FlightSabers is building toward
FlightSabers is developing the battery thermal management systems, power distribution units, and ground charging infrastructure that make long-haul electric flight possible.
The physics of electric flight are proven. The thermal management, power distribution, and charging infrastructure to operate it commercially does not exist yet.
Heat generation scales with the square of charge rate. Megawatt-level fast charging drives cells beyond safe operating temperatures long before commercial turnaround windows are met.
Commercial electric aviation requires 1.5–2 megawatts of charging power per aircraft stand. Today's airports and electrical grids were never designed to deliver that.
Automotive thermal management systems are too heavy for aviation. No system designed specifically for aviation-grade battery fast charging exists today.
Charging power — today's infrastructure vs. aviation requirements
FlightSabers is building three integrated systems that together solve the thermal, power distribution, and ground charging challenges of electric aviation.
Aviation-grade active cooling architecture engineered specifically for solid-state lithium-sulfur cells. Maintains safe cell temperatures throughout 30-minute fast charge cycles within strict aviation weight budgets.
Core ProductHigh-voltage DC power distribution architecture connecting battery pack to propulsion motors. Redundant safety systems, solid-state circuit protection, and fault-tolerant design for aviation certification.
In DevelopmentMegawatt-level airport charging systems with intelligent power management. Battery energy storage buffers grid constraints while delivering 1.5-2 MW charging power for commercial turnaround times.
RoadmapFlightSabers is pursuing a research license for NASA's SABERS solid-state lithium-sulfur battery technology — the most advanced aviation battery chemistry in existence.
NASA SABERS cells achieve over 500 Wh/kg — nearly double conventional lithium-ion. This energy density is the threshold that makes long-haul electric aviation viable.
Replacing flammable liquid electrolyte with a solid composite eliminates the primary thermal runaway risk — the most critical aviation battery safety concern.
Sulfur-selenium cathode on graphene scaffold enables lightweight bipolar cell stacking — reducing pack weight while maximizing energy density.
We don't develop cell chemistry — we build the complete thermal management and power systems that make SABERS cells fly safely in commercial aircraft.

"The physics of electric aviation are solved. The infrastructure to support it is not. FlightSabers exists to build that infrastructure — starting with the thermal management systems that let batteries charge fast enough for commercial operations."
