SV-BAT-320 Backup Battery Installation
SkyView System Installation Guide - Revision AA 9-3
Location should be near the rear of the SkyView display. A 24” cable is included on the SV-
HARNESS-D37 for connecting the SV-BAT-320. This cable should not be extended.
Avoid locations that are subject to severe vibration.
Avoid locations that are subject to extended temperature ranges. The SV-BAT-320 has a
narrower operating temperature range than other SkyView modules.
Avoid locations that are subject to extreme humidity.
Leave room for electrical connections.
Mounting hardware is not included with the SV-BAT-320. The mounting tabs on each side of the
module have holes sized for #8 fasteners. Button head style AN hardware is recommended as
spacing between the holes in the tabs and the body of the enclosure limits what style tool can
be used to tighten certain fasteners. Follow recommended torque practices when tightening
the mounting hardware (see Caution below).
The SV-BAT-320 enclosure is made of plastic that may crack if too much torque is
applied to the fasteners and the mounting tabs of the SV-BAT-320. The
appropriate amount of torque that should be applied is a combination of the
mounting base material, its thickness, the fastener, the presence or absence of
thread lock compound on the fastener, and the tolerance stack up of the
diameters of the mounting hole and the fastener. Apply sufficient torque that the
fasteners will not self-release, but not so much that the mounting tabs will
eventually break from too much stress.
Use of ferrous fasteners in this location is acceptable. Do not rivet the SV-BAT-320 to the
aircraft as this will hinder future removal if necessary.
Electrical Connection
For warranty replacement, an SV-BAT-320 that is received at Dynon Avionics with
a different connector than the factory-installed connector is not eligible for
warranty replacement.
Connect the SV-BAT-320 module’s connector to the mating connector on the SV-HARNESS-D37.
If you are constructing your own SkyView display harness (equivalent to the Dynon Avionics SV-
HARNESS-D37), do not cut off the connector on the SV-BAT-320 to install a different connector.
See Appendix C: Wiring and Electrical Connections, Non-Dynon Avionics Wire Harness
Considerations for details on the mating connector for the SV-BAT-320.
Charging the SV-BAT-320
Do not attempt to charge the SV-BAT-320 using any other charging unit. Doing so,
at a minimum, risks ruining the SV-BAT-320, and at worst may cause the battery to
explode. The only safe method of charging an SV-BAT-320 is to connect it to a
SkyView display.
