Features
▪
Power button - The power button is located at the rear of the unit. It provides audible and tactile
feedback when pressed and is recessed into Voyager’s housing to prevent inadvertent activation.
▪
Liquid crystal display (LCD) - An LCD communicates
Voyager’s state of charge and mission
readiness.
▪
Battery management unit (BMU) - The battery management unit is an electronic safeguard that
continuously monitors critical functions and metrics. The BMU will activate redundant safeties that
disconnect Voyager if a metric is outside acceptable limits.
▪
Internal charging circuit - Voyager can recharge using power from an aircraft or from 110 / 220V
power grids through a power supply.
▪
Shell -
Voyager’s high-visibility shell is made of fire-retardant material and is water resistant.
▪
NATO connector -
Voyager’s NATO connector plugs directly into an aircraft’s external power
receptacle. Alternatively, a six-foot extension cable is available for pilots who prefer to place
Voyager on the ground during use.
Liquid Crystal Display (LCD)
Voyager’s LCD communicates the state of charge and the health of the battery. When Voyager is powered
“on,” the Avion Power logo and the aggregate start count are displayed. The start counter tracks the number
of engine starts and will increase when the discharge current is above 300A for at least five seconds.
State of charge
After Voyager is powered “on,” the LCD will display the state of charge. A green backlight will be lighted
when the state of charge is greater than 30%. The backlight changes to yellow when the state of charge is
less than 30%.
Operators should familiarize themselves with the capacity used during various tasks and ensure adequate
state of charge before starting the aircraft or beginning maintenance.
Voyager exhibits minimal self-
discharge, losing only 3% per month when “off.” Voyager has no memory
effect and can be fully discharged without harming the battery.
NOTE: The actual state of charge may differ from the displayed state of charge by +/- 10%.
Voyager’s state
of charge is updated every five seconds.
