I hope this is in the correct place. Anyway, I bought some 18650 batteries from 4sevens.com and I noticed that a quantity wasnt listed. They were $16.00, and I was told that it was per battery. I found another guy online that said that they were $8.00 each from 4sevens. just want some clarification, since I ordered "2", am I getting 2 batteries, or 4?
