About EarthX Batteries

Advanced Lithium Battery Technology, Engineered in the USA

EarthX Batteries is an USA based battery manufacturer and engineering company specializing in lithium iron phosphate (LiFePO4) batteries for aviation, motorsports, powersports, automotive, and specialty applications.

Founded in August 2009 by a Navy veteran and electrical engineer with a passion for trail riding, EarthX was created with a simple goal: develop a lighter, higher-performing alternative to traditional lead-acid batteries.

Today, EarthX designs, engineers, and manufactures advanced lithium batteries for applications where weight, starting power, reliability, safety, durability, and performance matter.

From motorcycles and ATVs to race cars and certified aircraft, EarthX focuses exclusively on battery technology and the applications in which our batteries operate.

Our Story

EarthX began with a practical problem. Traditional lead-acid battery technology had been around for more than 170 years, yet many modern vehicles still relied on batteries that were heavy, inefficient, and limited in performance.

After years of research, development, testing, and engineering, EarthX introduced a new generation of lightweight lithium batteries designed specifically for real-world starting and power applications.

What started in the powersports market has grown into a battery company serving customers across aviation, motorsports, powersports, automotive, and specialized industries.

Our product development philosophy remains the same: understand the application, engineer the battery around its requirements, and provide customers with a reliable, high-performance solution.

EarthX Lithium Battery Technology

EarthX batteries use Lithium Iron Phosphate (LiFePO4) technology combined with an integrated Battery Management System (BMS).

LiFePO4 chemistry provides an excellent combination of power, durability, stability, and long service life. The EarthX BMS adds electronic monitoring and protection to help manage battery operation and provide important battery information.

Compared with conventional lead-acid batteries, EarthX lithium batteries can provide significant advantages, including:

• Approximately 80% less weight in comparable applications
• High starting and cranking power
• Higher resting voltage for strong, stable engine starts
• Longer battery service life
• Low self-discharge
• Integrated electronic battery management
• No liquid electrolyte
• No acid spills or electrolyte loss
• No lead-acid sulfation
• No caustic battery acid
• Improved performance in applications where reducing weight is important

These characteristics make lithium battery technology particularly valuable for aircraft, race vehicles, powersports vehicles, and other performance-driven applications.

EarthX Aircraft Batteries

Lithium Batteries for Certified and Experimental Aircraft

EarthX has developed extensive expertise in aviation battery applications and offers lithium batteries for both experimental aircraft and FAA-certified aircraft.

EarthX was the first company to receive FAA approval for a 12-volt lithium battery for certified aircraft, establishing an important milestone in the adoption of lithium battery technology in general aviation.

Since then, EarthX has continued expanding its FAA-approved aircraft battery applications through Supplemental Type Certificates (STCs).

EarthX FAA-approved lithium battery applications include aircraft manufactured by companies such as:

Beechcraft, Cessna, Commander, Diamond, Grumman, Mooney, Piper, Socata, and Swift.

EarthX offers approved battery solutions for both 12-volt and 24-volt aircraft electrical systems, with specific battery applicability determined by the applicable aircraft model and FAA approval.

For aircraft owners, operators, mechanics, and aviation professionals, EarthX batteries can provide substantial weight savings while delivering high starting power, stable voltage, long service life, and integrated battery management.

Lithium Batteries for Motorsports and Racing

EarthX lithium batteries are also engineered for high-performance motorsports applications.

Our batteries have been used in racing environments where weight reduction, starting performance, vibration resistance, and reliability are critical.

EarthX has proudly supplied batteries to Indy race car teams for more than five years, providing lightweight battery solutions for demanding professional racing applications.

The same engineering principles used in motorsports: high performance, low weight, reliability, and application-specific design.

Lithium Batteries for Powersports and Automotive Applications

EarthX originally developed its reputation in the powersports market, and powersports remains an important part of our business.

EarthX lithium batteries are available for applications including:

• Motorcycles
• ATVs
• UTVs
• Snowmobiles
• Scooters
• Race vehicles
• Automobiles
• Other recreational and specialty vehicles

Our batteries are designed for customers who want to replace conventional lead-acid batteries with a lighter, higher-performance lithium alternative.

Custom Battery Solutions

Not every application can be solved with an off-the-shelf battery.

EarthX provides custom battery engineering and battery solutions for specialized applications where standard batteries may not meet the required size, weight, electrical, environmental, or performance requirements.

Our engineering team understands that a battery is not simply a collection of cells. Battery performance depends on how the battery interacts with the vehicle or equipment in which it is installed.

EarthX works with customers to understand application requirements and develop battery solutions designed around those needs.

Engineering and Battery Management Expertise

EarthX does one thing and does it well: batteries.

Our focus is dedicated to the design, engineering, function, reliability, safety, and performance of lithium battery systems.

We understand the importance of designing a battery around its application rather than treating the battery as a generic component.

Our engineering expertise includes:

• Lithium battery design
• LiFePO4 battery technology
• Battery Management Systems (BMS)
• Starting and cranking applications
• Aviation battery applications
• Motorsports battery applications
• Powersports battery applications
• Custom battery development
• Application-specific battery engineering
• Battery safety and protection
• Weight reduction and performance optimization

This application-specific approach allows EarthX to develop batteries for demanding environments where conventional batteries may not provide the desired combination of weight, power, reliability, and service life.

Our Mission

Our mission is to make advancedm modern battery technology accessible to more people and more applications.

We believe customers should not have to accept outdated battery technology simply because it has been around for generations.

EarthX is committed to continuing the development of safe, reliable, lightweight, high-performance lithium batteries for the vehicles and equipment of today and the technology of tomorrow.
