Engineered for Military Needs
Our Defender Series products were developed to maximize mission duration by providing vital range-extending power as well as lightweight battery chargers for use in the field. All ITAR-free.
Core advantages of Defender products:
Operate on locally available propane
Significant weight advantage over traditional portable battery options
Specifically designed for expeditionary uses
Fuel consumption dependent on load, to maximize mission duration
Excel even in extreme temperatures
Need no routine maintenance
Benefits Of The Defender Series
They’re highly durable — thanks to our proprietary microtubular design which offers built-in redundancy. Offering more power at a lighter weight and with quieter mechanics than is possible with other portable power options like batteries.
Run on Propane
Readily available anywhere in the world.
At 60 dB (A), Defender products are as quiet as a computer and hard to detect.
Pound for pound, Defender products produce 6x more energy than batteries due to the energy density of propane.
Limited moving parts means systems require no routine maintenance.
Rigorous shock, vibration and drop testing ensures systems won’t be damaged in transit and will perform in any environment.
Heat-resistant ceramic tubes keep Defender products excelling even in extreme temps, from -40°C to 50°C.
Fuel consumption rate dependent on load conditions to maximize mission duration.
Systems start at just 5 lbs, minimizing impact to combat load.
Microtubular design provides built-in redundancy, so the system stays up even if a tube inside the stack fails.
Defender Series Products & System Components
Explore all options available in the Defender line, along with key components that make up a full system.
D350 Portable Power
Backpack-sized 350W SOFC that runs on propane and offers 30 mission cycles or 600 total hours of operation. This ground-based unit powers battery chargers, so field personnel can recharge without returning home.
D350XR Range Extender
Lightweight and rugged power system that keeps drones flying longer and unmanned ground vehicles roaming farther – up to 30 cycles or 600 hours. D350XR is preferred by the world’s largest military contractors and is the only fuel cell in its class running on propane.
D450 Range Extender
450W SOFC that runs on propane and offers 60 mission cycles or 2,500 hours of continuous operation. Developed with Lockheed Martin for the Stalker XE UAS.
Military Use Cases
Defense applications require lightweight power sources that are quiet, small, hard to detect — and long-running. Lives depend on it.
Unmanned Ground Vehicles
From search and rescue to ordnance disposal, UGV keep soldiers safer and can’t stop to refuel.
Unmanned Aerial Systems
Reliable, lightweight power keeps drones up until the mission is complete.
Unattended Ground Sensors
Data collection is key for intelligence, where deployment time is critical.
Remote Battery Charging
Soldiers in the field can’t return to base every time they need to recharge.
Safety is at risk if ISR missions are cut short because of low power.
Designed to Maximize Mission Endurance
Defender Series SOFC are silent, lightweight range extenders that run on propane and offer a 6x increase in mission duration over batteries.
Defender products are designed to maximize power-to-weight, providing unparalleled energy and mission duration. They electrochemically convert propane into power to charge onboard batteries. SOFC are so efficient that they can replace 90% of batteries, for a sixfold increase in mission duration.
And because these systems operate on LPG — readily available anywhere in the world — logistics support is simple.
The SOFC are engineered for all-weather performance. They tolerate fine dust and rain and will not freeze. That’s because they are made of heat-resistant ceramic tubes and can store, start and operate from -20°C to 55°C.
