EarthX batteries are designed to be a replacement of a standard 12 volt lead-acid battery, but their nominal voltage is 13.2V so it will spin your engine faster than you would ever believe possible! Our batteries will work with any vehicle charging system that regulates the voltage between 13.9V and 14.6V, which is standard in all modern vehicles from motorcycles to aircrafts. And our batteries are an exceptional value given the fact they last longer than a lead-acid battery and weigh up to 80% less than a lead acid.

Backcounty Super CubsThere is a lot of talk about lithium batteries these days, but not all lithium batteries are equal. There are dozens of different types of chemistry used in lithium batteries. The EarthX batteries use cells made of Lithium Iron Phosphate (LiFePO4) chemistry that was developed in the U.S.A. This chemistry is the highest performance, most robust and the safest on the market today.

Inside every one of the ETX series batteries is the proprietary microprocessor Battery Management System (BMS) that monitors the charge level of each cell and balances the charge when needed, plus protects the cells from overcharge, over-discharge, short circuit and excessive heating.  Additionally, the EarthX aircraft BMS has redundancy circuits and a remote fault light indicator to alert you to the health and state of charge of the battery. No wonder why so many OEM aircrafts are switching to the EarthX battery!

Backcountry Supercubs are centered in Douglas, Wyoming, where engineers and craftsman deliver the evolution of what a true working class experimental aircraft can be.

The company started in 1998 under the name Smith Aviation, producing kits just outside of London, Ontario (1 ½ hours north of Detroit, MI).

After producing over 100 kits under the new name, and not having turbine engines to offer to customers, it was decided another name change was needed.

In 2008 we established a relationship with Wayne Mackey from Miles City, Montana.

Over the years we have discovered the only way to stay competitive, has been the extensive use of CNC Machines.

In our wings we literally make everything except the nuts and bolts.
