    Wondering if i should buy these! Many websites sell 2 of these batteries for about the same price as on here. I have quite a few friends who have ordered off this site and I'm getting mixed answers on whether I get 2 batteries for this price or if I should go to the cheaper priced websites. Thank you for the help :)

    Already reviewed but wanted to add that these last way longer than my old generic battery. I barely have to switch batteries once a day

    Got here in less than a week with free shipping, thanks again elementvape. Have only been using these for an hour but my friend uses these every day at 80 watts and never had a single problem. Recommend

    I've tried every battery on the market today, I bought these after I couldn't find the Sony vtc's I had been getting for my mod. I put the Samsung batteries after a fresh charge in my ipv3 and they lasted all day on a Subohm build .2ohm dark horse. I have an older pair that last 5hours of heavy vaping. I vape at 70watts and they barely ever get hot. In my stingray they are decent too. I use to change out my batteries after 3hours with these I get around 4hours depending on how much I vape. I don't buy anything else because you can never tell if you're going to get a legit battery. I haven't seen any fake Samsung batteries. Plenty of fake Sony and efest batteries going around. I wouldn't buy these from anyone on eBay or Amazon, but I would buy them from this site.
