Products: Lithium Ion Aircraft Battery

When you need a reliable power source for your aircraft, you can count on Spear Power Systems. Our lithium ion aerospace batteries are designed to meet the unique demands of flight. Whether you need a powerful energy storage solution for a military aircraft or you need to power medical helicopters, our lithium battery design can get the job done.

We provide a reliable battery for the aviation industry because reliability is the one thing that cannot be sacrificed in an energy storage solution. You need energy you can rely on so you can focus on the important task at hand.

As the world’s leading innovator in advanced lithium-ion battery systems, Spear utilizes their cell-agnostic approach to create exceptionally light and powerful energy storage systems. Projects delivered under the Aero brand bring Spear’s ingenuity and relentless commitment to safety to the defense and aerospace industries.

Our batteries are lightweight and compact, making them ideal for use in aircraft. And because they are not based on traditional lead-acid technology, our batteries are environmentally friendly and free of the toxic chemicals that can pose a risk to human health.

Aerospace Energy that Remains Cool Under Pressure

Aero’s custom capability allows Spear to configure products for the demanding environments associated with these applications—beneath the sea, on the battlefield, or above the clouds. Aero batteries optionally feature Spear’s proprietary flame arrestor technology—capable of mitigating emergency gases within the battery—venting them to the external atmosphere at a mere 30° Celsius.

Our technology works to prevent battery malfunction and battery fire so that aircraft applications can go off without a hitch. Spear has created a lithium ion battery system designed to avoid all potential hazards, no matter what external pressures are exerted on the battery system. Whether you’re operating a cargo aircraft or a Boeing jet, the li-ion batteries need to perform properly. You don’t want to be grounded or forced to make an emergency landing due to thermal runaway, over discharge, or a battery cell defect.

To Infinity & Beyond—Lithium Ion Aircraft Systems That Go the Distance

Spear's Aero line of batteries is perfectly situated to power up unmanned aerial vehicles, propel them through the skies, and even provide the necessary energy to run advanced on-board applications without weighing down the system or hindering efficiency. That same streamlined design contains highly redundant safety features - making it an ideal power source for satellite launch vehicles. The Aero line also provides unique solutions that support the U.S. and allied warfighters—whether powering advanced directed energy or manned and unmanned underwater, ground, and aerial vehicles.

Spear has over a decade of experience in providing power from 8,000 meters beneath the surface of the sea to thousands of meters in the air. You can count on us for energy storage devices with the right voltage for your aero application.
