>>3073223as long as its a nice battery and you're not using it as you shoot, the worst that'll happen is it'll detonate on your chest, hip, or table top.
Regardless, spare insertable batteries are superior in every way other than the cool factor and being able to charge other stuff with it. For the price OP spent on the bracket, hot shoe mount, cable, and battery he could have afforded a couple spare 3rd party batteries. This is clearly a fashion statement. That being said, I think it's super cool OP, thumbs up.
