Hi friends. As you know counterfeit batteries are always a big issue. I recently bought some new batteries for my ipv4s which takes two 18650 and must be at LEAST 35 amp batteries. To my surprise when my batteries arrived each battery was labeled with its own anti-counterfeit. service sticker with the ability to scan each battery to insure it is legit and not re-wrapped or counterfeit. I thought this is a wonderful way to ensure authentic batteries. so I'm assuming that you will now be able to check on all authentic batteries now via thir stickers. Be aware of cheap batteries as they might not be what you thought they are. I just wanted to share about the anti-counterfeit service sticker they are now offering. I think it's a great way to check the product. similar to a authentication sticker you recieved on genuine vaping products, just not scratched off but scanned easily with a scanner app from your phone . I'm glad this service is now offered because it was getting more difficult to tell counterfeit from genuine batteries. Having this sticker available is very helpful.
