ePropelled, a global leader in intelligent electric propulsion and power management systems, today announced a major 2026 expansion of its Hercules starter generator product line, further strengthening its position in hybrid propulsion for uncrewed aerial, ground, and marine platforms.

Building on its proven Hercules architecture, the expanded lineup introduces new scalable configurations, enhanced intelligent power integration, and expanded customisation options to meet the evolving needs of OEMs and system integrators worldwide.

Expanding the Hercules Platform for Next-Generation Missions

The Hercules starter generator family is engineered to deliver hybrid-ready power solutions that combine electric efficiency with combustion engine endurance. Current systems span a wide power range, from approximately 500 W to 12 kW, enabling extended mission duration, improved payload capacity, and reduced acoustic signatures for uncrewed systems.

The 2026 expansion builds on this foundation with:

– Broader power class offerings and refined performance tiers

– Enhanced thermal resilience for high-temperature and high-altitude environments

– Improved power density and reduced system weight

– Expanded integration with intelligent power electronics and control systems

The Hercules series includes multiple starter generator models, along with complementary intelligent power systems and controllers designed for seamless hybrid propulsion integration.

Intelligent, Connected, and Adaptive Power

A defining feature of the Hercules platform is its integrated intelligence. Through 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 enables:

– Real-time diagnostics and predictive maintenance

– Mission-specific performance tuning

– Data-driven optimisation of propulsion efficiency and endurance

The 2026 expansion further enhances these capabilities with tighter integration into ePropelled's growing ecosystem of electronic speed controllers (ESCs) and Intelligent Power Systems (iPS), delivering improved energy distribution, system coordination, and operational reliability.

New Customisation Options for OEM Integration

To meet the diverse requirements of advanced mobility platforms, ePropelled is introducing expanded customisation options across the Hercules line, including:

– Configurable power outputs tailored to mission profiles and vehicle class

– Flexible mounting and form factors for air, land, and marine platforms

– Custom control interfaces (CAN, digital triggers, and hybrid control architectures)

– Integrated starter-generator-to-propulsion motor conversion for boost and manoeuvring support

– Application-specific power management systems for avionics, payloads, and onboard systems

These configurable elements allow OEMs to deploy Hercules systems as fully integrated hybrid power units or as modular components within broader propulsion architectures.

Supporting Rapid Growth in Hybrid Propulsion

The expansion comes amid accelerating global demand for hybrid propulsion systems capable of delivering longer endurance, greater efficiency, and operational flexibility across uncrewed platforms.

ePropelled's continued investment in manufacturing, including new global innovation infrastructure and vertically integrated production capabilities, positions the company to scale output and support next-generation aerospace and autonomous system programmes.

"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."
