The EarthX Battery Backup System (EBBS) is engineered specifically for avionics and critical aircraft electrical systems. The EBBS can be used as a secondary power source for equipment with a second power source input or as an uninterruptible power source (aircraft power pass-thru with battery backup) for equipment with a single power input.

It is a “all in one package” backup power source solution including a LiFePO4 battery, a battery management system, battery charger, battery power monitoring, circuit protection (auto resetting fuse), battery fault/status for the pilot, pilot enable/disable control, and automatic transfer to backup power on loss of the primary power (uninterrupted power supply).

It can be used to power:

• Electronic Flight Instrumentation Systems (EFIS)
• GPS
• Engine Monitors
• Transponders
• Electronic Ignition

The EBBS connects to the aircraft electrical bus and provides output power to critical equipment that requires two power sources or a high reliability power source. The EBBS acts as an un-interruptible power source by passing aircraft electrical bus power thru the device when the bus voltage is within a normal range (11.5 – 15 volt), but switches to the internal battery power when the bus voltage drops below 11.5 volts or goes above 15 volt. An additional benefit of the EBBS is voltage sag protection, allowing operation of critical equipment during engine starting.

The EBBS has five power outputs suitable for use with equipment such as Garmin GNS and GTN series navigators, Garmin EFIS, Dynon EFIS, Grand Rapids Technologies EFIS, Advanced Flight Systems EFIS, and MGL EFIS, Trio Autopilots, and TruTrak Autopilots.

In aviation, backup power isn’t a luxury, it’s a lifeline. Earthx’s advanced lithium backup battery is engineered specifically for avionics and critical electronic systems, delivering uncompromising reliability when it matters most.

• Critical for flight safety: Provides power to essential systems like electronic ignitions, communication, navigation, other critical electronics and flight control when the main electrical systems fail.

• Redundancy: Offers a secondary power source that ensures continuous operation of avionics, reducing the risk of catastrophic failure.

• Cockpit displays (EFIS, EICAS), GPS, and transponders remain operational during emergencies.

• Enables pilots to:

  • Communicate with ATC

  • Navigate safely to an alternate airport

  • Conduct safe landings in case of total electrical loss

Output Current: 8 amps continuous, 12 amps peak

Temperature range: Operating: -30 C to 65 C
