Hi and lovely to welcome you to this fabulous place
I had my implant in August 2010 for Failed Back Syndrome and neuropathy in both legs........
My battery is located in my left hip/butt also.....just on or below my belt line, depends on whether I wear hipsters or not
I dont have any issue with it there at all. As Im right handed I find it handy when Im turning my stim up and down as I hold the wand over the battery with my left hand and adjust the controller with my right hand....sorted
Its a personal choice I would say, which ever you feel you would be comfortable with. But mine is out of the way and never a nuisance either
