Larry,
I just completed an upgrade to my panel and it's similar to yours, HXr (with autopilot, EIS, SkyRadar) and a Dynon D10A with the internal battery backup. I have a 14v system, single battery and alternator. I kept my Garmin GPSMAP 496 since it has it's own battery. I plan to add a backup battery for the HXr as well. GRT told me that at 14v you need at least a 3AHr battery. I'm looking at the inexpensive rechargeable batteries used in alarm panels. I plan to rig up the battery with a recharging circuit and connect it to the HXr and AHRS secondary power inputs.
Here's a picture of my panel in flight: http://www.grtavionics.com/forum/viewtopic.php?f=19&t=189.
If I had a complete power failure I would still have the HXr, Dynon and 496 along with a handheld NAV/COM all powered by batteries. I personally prefer this over a second alternator, etc. for its simplicity.
If anyone is interested I'm selling off a lot of the stuff I took out of the panel:
- Garmin/Apollo SL70 transponder with Trans-Cal SSD120 digital encoder
- S-TEC 50 2-axis autopilot with turn-coordinator, includes servos, pitch sensor, harness, hardware, ST-901 GPS Steering ARINC-429 interface
- Sigma-Tek 4000C vacuum directional gyro with autopilot heading bug output, 14v lighting
- Mid Continent MD200-306 CDI, 14v lighting
- Apollo ACU GPS/NAV switch, vertical, 14v
- Aerosonic Altimeter Model 101720, 14v lighting
- United Airspeed Indicator Model 8030, 14v lighting, marked for Velocity RG
- United VSI Model 7000, 14v lighting
- Rapco Vacuum Pump model RA216CW with vacuum regulator, vacuum gauge
Here's a picture of my old panel showing most of this equipment: http://elegant-productions.com/IMG_0527.JPG
Individual photos and documentation for this equipment is also available. Please contact me for pricing.
Regards,
Glenn
