According to EarthX, lithium-ion batteries are significantly lighter than traditional lead acid batteries.

“If you’re replacing the Concorde RG24-11 lead acid battery, you go from a 26.5-pound battery to a 7.2-pound battery—that is 19.3 pounds of instant weight reduction,” EarthX said in a statement. “That gives you a few more pounds of useful load.”

In addition, the life span of the EarthX battery is twice that of a lead acid battery. EarthX also points out that it cannot “freeze, boil over, lose electrolyte, corrode, or sulfate.”

For pilots who have ever been surprised by a dead battery, the EarthX has a battery management system (BMS) that communicates directly to the pilot if there is anything outside of normal operation through either a flashing or solid LED light.

“This provides useful information not only for the pilot, but also your mechanic, to make the best-informed decisions,” EarthX said.

Once the EarthX is installed, a new weight and balance for the aircraft needs to be done, as is standard procedure when an STC is applied. EarthX does the STC paperwork for the customer, free of charge.

The 24V TSO-certified battery is available for $999, and the 12V TSO-certified battery for $699.

The initial kit for installation ranges from $195-$295, depending on the airframe.
