R700 R600 on a 12v battery

[nigel_burton_6l]

I have a situation that I wish to run R700 or R600 on a 12V battery supply. I am wondering what the voltage tolerance for these devices might be or is 12V regulated the only option, other than POe.
One concern is the battery at full charge can be 16V, but it is a V-lock so it has a low voltage cut off of around 11V. Can the R700 or R600 handle this voltage range in the 12V power input.?

I have an R320 in my office, flipping it over I can see Ruckus asks for 12v 1A on a barrel connector.
As I search through the specs for R600's power requirements show to be the same.
PHYSICAL CHARACTERISTICS Power • DC Input: 12 VDC 1.0A • Power over Ethernet 802.3 af

on the R700, you'll need more amperage. 
Power • DC Input: 12 VDC 1.5A • PoE: 802.3af compliant

if I were you, I would put a power supply in front of the Ruckus, and have it regulate your 12v-16v down to where the Ruckus unit would want it.
If you want to impress your friends and peers, I'd put one of these Netonix units on your 11-16v power supply THEN have it feed the 48v back to the ruckus units. Bonus points - if an AP goes down you can still reboot it remotely via the switch!

I hope that helps, otherwise, look hard at a solid Buck-Booster similar to this one here.
