With EarthX, you gain the quality and performance you want from your lithium batteries. Our experienced team commits to innovation and industry best practices to deliver batteries you can trust. We only source high-quality materials for our batteries, and we support every product with attentive customer service. The aircraft specific batteries are the ETX Hundred series, do not use the power sport batteries as they do not have all the same safety features as the aircraft specific ones.
As a veteran-owned, U.S.-based company, we’re proud to provide the batteries you require for your experimental aircraft.
Advantages Of Utilizing EarthX Batteries For Experimental Aircraft
EarthX lithium batteries offer many benefits for experimental aircraft, including:
- Lightweight materials: Our lithium batteries use cutting edge technology that lead to a much lighter battery and more powerful batteries as compared to lead acid counterparts. There’s about an 80% weight savings over a comparable lead acid battery for instant weight savings. Example: the PC680 weighs 15 pounds and has 170CCA. The EarthX ETX680 weighs 4 pounds and has 320CCA. Lighter weight makes installation easier and improves the handling of your aircraft.
- Increased cranking power: EarthX Batteries do not experience the large voltage drops as lead acid batteries experience to provide you a consistent and powerful startup every time you use your aircraft.
- Safe performance: EarthX Batteries feature a state-of-the-art Battery Management System (BMS) that monitors performance and prevents overcharging and over discharging. The BMS is key to the longevity of our batteries.
- Long-lasting: With the help of the BMS, our lithium batteries can last up to six years, even with heavy use in your experimental aircraft.
Our Commitment To Powering Aviation
EarthX lithium batteries are designed for a wide range of experimental and homebuilt aircraft. Our batteries are used in amateur-built (E-AB) aircraft, experimental aircraft, kit-built aircraft, and other aircraft applications where lithium battery technology can provide advantages over traditional lead-acid batteries.
Lithium Batteries For Experimental Aircraft
EarthX develops lithium iron phosphate (LiFePO4) aircraft batteries for pilots, aircraft builders, and aircraft owners looking for a modern alternative to traditional lead-acid aircraft batteries.
Experimental aircraft and homebuilt aircraft provide builders with the flexibility to select components that meet the needs of their individual aircraft. EarthX lithium aircraft batteries are available for a variety of 12V and 24V electrical systems and are used in applications ranging from newly built kit aircraft to existing experimental aircraft.
Whether you are building an aircraft from a kit, replacing the battery in an existing homebuilt aircraft, or selecting components for a new experimental aircraft project, EarthX provides lithium battery options designed specifically for aviation applications.
Batteries For Homebuilt And Kit Aircraft
Choosing the right battery is an important part of building or maintaining a homebuilt aircraft. Aircraft builders consider factors such as battery weight, starting power, capacity, electrical system voltage, charging requirements, battery size, and available installation space when selecting an aircraft battery.
EarthX lithium aircraft batteries use Lithium Iron Phosphate (LiFePO4) chemistry and provide a lightweight alternative to conventional lead-acid batteries.
Our batteries are suitable for a variety of experimental aviation applications, including:
Experimental aircraft
Homebuilt aircraft
Amateur-built (E-AB) aircraft
Kit-built aircraft
Experimental Light-Sport Aircraft (E-LSA), where applicable
Aircraft under construction
Aircraft undergoing battery replacement or upgrades
Custom-built and modified aircraft
Why Choose A Lithium Battery For An Experimental Aircraft?
Lead-acid batteries have been at the forefront of aircraft power for decades, but we want to see change. Our developments in lithium iron phosphate batteries offer greater power, performance, and safety for aircraft of all types.
For experimental and homebuilt aircraft, reducing unnecessary weight can be especially important. A lighter aircraft battery can contribute to overall aircraft weight savings while providing immense starting power.
EarthX lithium aircraft batteries are designed to provide:
Lightweight lithium battery technology
High cranking power
Lithium Iron Phosphate (LiFePO4) chemistry
12V and 24V aircraft battery options
Battery management technology
A modern alternative to traditional lead-acid batteries
Aircraft-specific battery options for a variety of applications
Longer-lasting battery
Aircraft Battery Replacement For Experimental Aircraft
If you are replacing the battery in a homebuilt or experimental aircraft, it is important to select a battery that is appropriate for the aircraft’s electrical system and installation.
When choosing an EarthX battery, aircraft builders and owners should consider the aircraft’s electrical system voltage, existing battery specifications, charging system, engine starting requirements, physical battery dimensions, and the specific EarthX battery’s application requirements.
Use the drop-down selections (the green “CLICK HERE TO FIND WHAT BATTERY YOU NEED” button at the top of the screen) to see what battery you need for your engine size.
EarthX provides aircraft battery information and installation guidance to help builders and owners select the appropriate battery for their application.
EarthX Batteries For Aircraft Builders
We understand that experimental aircraft builders are looking for ways to improve their aircraft while maintaining reliability and safety. That’s why EarthX works to develop battery technology specifically for aviation rather than simply adapting automotive lithium batteries for aircraft use.
Our goal is to provide purpose-built lithium aircraft batteries for pilots, aircraft builders, homebuilders, and manufacturers who are looking for an alternative to conventional lead-acid aircraft batteries.
We also have custom battery boxes that fix EarthX batteries to help you with an easy installation/removal during the building process.
New aircraft/kit planes on the market come with EarthX Batteries straight from the manufacturer.
We have goals in the aviation industry to make changes for the betterment of all, and we’re offering our support wherever we can as a Veteran-owned and operated company in the USA.
Powering The Future Of Experimental Aviation
From homebuilt aircraft and kit planes to experimental aircraft and new aircraft designs, EarthX is committed to advancing aviation battery technology.
Our mission is to make lithium battery technology more accessible to the aviation community while continuing to develop batteries that provide the power, performance, weight savings, and safety pilots and aircraft builders expect.
Whether you are researching a battery for a new homebuilt aircraft, building a kit aircraft, replacing an existing experimental aircraft battery, or looking for a lightweight lithium aircraft battery, EarthX is developing solutions to help power the future of aviation.
