Cold-weather power for long-endurance drones.
Ptarmigan Dynamics is developing high energy density battery packs and heated charging cases so drones can keep flying, and charging, in the cold. We work with drone makers to fit them to their aircraft.
Flies, and charges, in the cold.
Packs designed to fly at −30 °C, and a heated case that makes charging in the field practical all winter.
Sized to your aircraft.
Modules of around 800 Wh at over 300 Wh/kg, configured to suit the aircraft they fly on.
Assembled in Canada.
Final assembly in Kitchener-Waterloo, Ontario, and you deal directly with the engineers who design the packs.
We fly our packs on our own aircraft. Our carbon-fibre demonstrator completed a 35-minute endurance flight on our first in-house pack in September 2026. See Willow-1
