Emergency Power for Amateur Radio

I published this article earlier today on the Southern Nevada MARA Website.  I am cross posting it here as well.

I recently added a battery backup for my ham radio station.  I am using a mobile rig as my base station.  On the right is a picture of my setup.  It features:

Mobile Radio Power-Werx’s 30 AMP Switching Power Supply with PowerPoles Diamond’s SX40C SWR meter KI0BK’s Low Loss PWRGate Power Sonic’s PS-12550U 55 Amp Hour AMG Battery Various Powerpole extension cables

Any questions on my setup?
What kind of power backup do you have for your radio rig?
