Here's the skinny on X-Sight vs Photon. If using it for night hunting only, the Photon is generally a better unit. The NV on it is better than the X-Sight plus it has historically had a smoother refresh rate at the expense of field of view/resolution (really the same thing, just depends on how you want to look at it) and day use. Can you use the Photon during the day, sure. Is it as good during the day as the X-Sight? Not by a long margin. Most of my customers like the features that are available during the day plus the amazingly better daytime picture so that's what I sell the most of.... we're talking about 5-1. Now, for the guys that are really into night hunting and want something dedicated for it, the photon is where it is at.
In regards to the x-sight battery pack... just get a cell phone recharge bar and use velcro and stick it to the side of your unit or the gun. Same freaking thing and 1/5th of the cost. Plus you can have several of them and hot swap them out as needed.
