SAMSUNG INR 18650 25R 2500mAh 20A

Product Review (submitted on 27 November 2016):

Bought a couple due to worries about Efest batteries I own (not bought here) and due to broken wrap on them too, due to Mini Book being very tight battery container and breaking the wraps. All the reviews online say that these are the batteries to have and that Efest aren't as safe, plus (I know very little about the mah) I doubt that the Efest 3500mah that I bought elsewhere is legitimate!

Charged them up and have been using since for about 28 hours, down to half charge (on 8.6w on a 2.13ohm coil). If I get 48 hours out of it I'll be happy!

Great service as always.
