Here are some applications our batteries work for:

Benefits of Using EarthX Batteries

If you currently use lead-acid batteries for your power, switching to our lithium batteries offers many advantages, including:

Weight Reduction

Lithium batteries are 80% lighter than lead-acid equivalents, meaning you get better performance and speed from aircraft or racing vehicles or seriously lighten the load of carrying around equipment that is battery operated.

Speedy Charging

These batteries charge two to three times faster than lead-acid so you enjoy less downtime during charging.


In the 12-volt series, you get a resting voltage of 13.28 volts which will crank over your engine faster and better. Lead-acid batteries get only 12.6 volts at resting voltage.

Long-lasting Usability

Typical life span for an EarthX lithium batteries is up to 6 years before you need a replacement.

Flexible Mounting

EarthX has a proprietary design that allows these batteries to be installed upside down or sideways without fear of leaking acid and damaging your vehicle or equipment. With the center terminals, you just need to rotate the battery 180 degress to have the polarity you need. Never order the wrong polarity battery again.

Environmentally Friendly Interior

Lead-acid batteries cause harm to the environment when they leak. Lithium batteries are nonhazardous, nontoxic and nonpoisonous. They will not sulfate, boil over, freeze or corrode.

EarthX Batteries also offer benefits over other lithium batteries. We provide a state-of-the-art comprehensive Battery Management System (BMS) that monitors charge levels and protects from overcharge or over-discharge. The BMS gives thermal protection, short circuit protection and built-in cell balancing.

We also test all batteries to industry standards, including SAE, UL and CE. We are the only lithium battery company to have 12V battery that meet FAA Technical Standard Orders (TSO), meaning they satisfy extreme safety standards for equipment used in general aviation aircraft.
