hello all, lately i was having a TONNNNNN of trouble with my trustfire 18650 batteries that came standard with my innokin itaste VTR. The choice was easy to switch batteries. I went to a reputable local vape shop and they set me up with 2 of these Panasonic NCR18650B Super Max 3.7V 3400mAh for 25$. I guess all im wondering is these are #1 a good battery choice for the vtr, #2 if these look like legit Panasonics, I was told they order their batteries right from Panasonic, and #3 for whoever else have these, how they are overall and how long do they last you on a charge. With my trustfires I would only get about 5 hours on a charge if that. Thanks Guys!
