EarthX is one of the original pioneers to enter the lithium -ion battery market, incorporating in 2009. EarthX has set the standard for others to incorporate a battery management system (BMS), which other brands are just now starting to offer. This is not an optional feature, but a requirement to have a safe, high-performance, long-lasting lithium battery. With over 13 years of experience and tens of thousands of batteries in the marketplace, this is a finely tuned BMS design as they are not all created equal.


EarthX is a veteran owned, USA company located in the beautiful Rocky Mountain state of Colorado. We have multiple incoming phone lines and emails so you can reach a person if you need support. EarthX stands behind the product and offers you unparalleled customer service.


EarthX mission was never to be the cheapest lithium battery on the market, but the best lithium battery on the market. This means using components of the highest quality, the widest operating temperatures, and understanding how the battery will work as part of the charging system of your vehicle and the demands it will encounter.


EarthX use scientific industry standards to provide the ratings of the batteries abilities. This means you will receive a battery that is rated to it’s true abilities vs. marketing specs.


A lithium battery needs to be monitored to avoid the continued use of a possible defective cell or battery that has used its useful life and no longer holds a charge, as all batteries do with age. The EarthX battery management system (BMS) is designed to do exactly this. As a testament to the quality and safety of this battery design, EarthX is the first company in the world to achieve a FAA approved 12V lithium battery for the aircraft market and has a 24V FAA approved lithium battery. This is an extremely government regulated market with years of testing and proof of the safety and performance of the EarthX batteries. You will not find any other brand with this level of approval.
