MOBIUS.energy is a fast-growing startup in Southern California with a mission to accelerate the transition to renewable energy. Mobius has developed a safe, high-power, and energy-dense battery module, Husky, optimized for electric aircraft. The Husky battery module has a market-leading high discharge rate that provides a power boost during the take-off and landing. Its high charge rate enables fast charging. The Husky’s independent modular architecture at a high voltage of 800 V includes an innovative thermal management system and a customizable battery management system (BMS). The modular approach enables radical simplification of the installation, maintenance, and removal of battery packs. Mobius will deliver its modules through a subscription model, including maintenance and salvage services. Repurposing its modules for a second life in the stationary market and providing end-of-life recycling will contribute to the decarbonization of the aviation industry.
