I am sitting here building my Amazon shopping list for accessories and glass that I plan to purchase for my newly founded Canon Rebel XS. I was looking at spare batteries as I would like to have a couple of spares that I keep charged. There are batteries on Amazon for as low as $9 from off brands. I am curious, coming from a guy with little experience, am I taking any real risk by using these cheaper batteries. The Canon LP-E5 is $46 on Amazon, am I buying just a label on the battery. Anyone else use off brand batteries in their Canon cameras?
