14.4v too much for 5v monitor?

So I'm thinking of getting a battery with D-Tap, so I can run both my camera and my Marshall V-LCD51 monitor from the same battery. The monitor instructions says "5v to 12v". The monitor says "5v" next to the DC input. Would I be risking damage to my monitor if I hooked it up to the 14.4v battery?
 
You'll break it, I had one break on me the first time I used it and I'm pretty sure it was because it was pickier about voltage than I'd expected (I think I plugged in 12v or 7.2v or maybe it was unregulated 14.4v but I don't think so) fortunately the store took it back when I returned it... And keep in kind that a 14.4v unregulated battery outputs around 16.8v when at full capacity which is definitely too much. I do remember the voltage input range specs on that monitor being a bit unclear...
 
Thanks for the advice, Noah and doubledark. I've decided to discard the D-Tap idea. I'll just use the small battery that's meant to attach to the back of the monitor. I thought D-Tap might simplify things for me, but it now looks like more trouble than it's worth.
 
For every post like this, asking the question first, there are 40 people out there who just tried it anyway and now have smoking hair. It reminds me of a quote: "A couple of months in the laboratory can frequently save a couple of hours in the library" (Frank Westheimer).
 
Since it is a 5v device you could use an inexpensive cell phone battery charger. The USB interface is a common 5v design, and if you can't find a ready-made cable from USB then you could hack one in a few minutes. That monitor doesn't take much power so a few of those cheap rechargeable batteries would run it all day and then some.
