EarthX Backup Batteries

EarthX batteries has two different backup batteries, the EBBS and the ETX104.

EBBS

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.

ETX104

The ETX104 is a lithium iron phosphate (LiFePO4) 4Ah battery with an integrated battery management system (BMS).  The BMS’s fault/status output (like the EBBS) can be connected into your EFIS or wired to a 12volt LED light on your instrument panel to alert you to the state of charge and state of health of the battery.

The ETX104 is a component of the backup back system, but relies on external circuits to manage redundant power sources.
