I'm new so this is the only place I can post. I finally figured out what I like - 501 LR Cartomizer. But 1 of my batteries is not working (I dropped it a couple times). The company I initially bought through hasn't any 501s in stock that can use the LR Carto - which I had ordered a bunch of. I've been brousing and am having trouble finding a place that has the battery I'm want and since my experience with companies is, well, extremely new, I was hoping someone with experience and knowledge could guide me in the right direction. I understand that soliciting is propably frowned upon but I don't know what else to do.
