ePropelled has announced a major 2026 expansion of its Hercules starter generator product line. The update targets hybrid drone propulsion and power solutions for uncrewed aerial, ground, and marine platforms.
Expanded Hybrid Drone Propulsion Lineup
The Hercules starter generator family spans approximately 500 W to 12 kW. The systems combine electric efficiency with combustion engine endurance. They enable extended mission duration, improved payload capacity, and reduced acoustic signatures for uncrewed platforms.
The 2026 expansion introduces broader power class offerings and refined performance tiers. ePropelled also improved thermal resilience for high-temperature and high-altitude environments. The updated systems deliver higher power density at reduced weight.
The Hercules series includes multiple starter generator models alongside intelligent power systems and controllers for hybrid propulsion integration.
Intelligent Power Management
The Hercules platform integrates with ePropelled’s ePConnected ecosystem. Systems provide real-time monitoring of voltage, current, RPM, temperature, and power output via CAN-based interfaces and open APIs. This supports real-time diagnostics, predictive maintenance, and mission-specific performance tuning.
The 2026 update tightens integration with ePropelled’s electronic speed controllers (ESCs) and Intelligent Power Systems (iPS). These improvements target energy distribution, system coordination, and operational reliability.
OEM Customization for Drone Applications
ePropelled now offers expanded customization across the Hercules line. Options include configurable power outputs tailored to mission profiles and vehicle class, flexible mounting for air, land, and marine platforms, and custom control interfaces. OEMs can also integrate starter-generator-to-propulsion motor conversion for boost and maneuvering support.
“This expansion of our Hercules starter generator line reflects the growing demand for smarter, more adaptable hybrid power solutions across uncrewed systems,” said Nick Grewal, CEO of ePropelled. “By combining scalable performance with deep customisation and intelligent power management, we are enabling our customers to extend mission endurance, increase system efficiency, and accelerate innovation across air, land, and sea platforms.”
ePropelled holds over 40 patents across 13 categories. The company operates R&D, engineering, and manufacturing facilities in the United States, United Kingdom, and India.
