Samsung INR18650-30Q High Drain 3000mAh 3.7V 15A Rechargeable Flat Top Battery, (8 Pcs)

Order was fulfilled by M&A BD Electronics and the batteries are definitely genuine. All weighed in at 47-49 grams and a discharge/charge test indicates between 3050 mAh to 3170 mAh. Definitely not re-wraps. Quality batteries.

I can't tell you if these are real Samsung or not but I can tell you I've had these batteries for a few months now and they hold their charge. I bought 14. My vape takes 5 and my friends takes 2. I got us each 2 sets. I only have to change my set every 2 days, which is really good for me, and my friend's last him a little over 24 hours, which is also good for him. I vape at 150 watts and he's at 130 so at that wattage the batteries last.

I bought the 8 pack, it’s difficult to find 18650 batteries that are NOT cheap knockoffs. I tested them immediately with a CT3400 charger, all 8 of them showed between 28XX and 29XX mAh to the specified 3000mAh capacity. This was just after one charge/recharge cycle, one can assume that it will reach full capacity after a few more charge cycles.Definitely not knockoffs

Best vaping batteries I've ever used!

Last longer than the green Samsung batteries in my vape.

These batteries reign supreme in my Thru-Nite TN42 flash light.

With so many counterfeit batteries out there, i was hesitant to order these, but am please to admit that these are authentic. Very low internal resistance and pack enough juice to vape all day long.

These have decent capacity and durability. I am seeing no difference in quality and consistency between them over a 2 month period of pretty continuous use.
