Hi guys. I am pretty new to vaping, I got a Fuchai Glo with a manta rta. The batteries I got with it were Samsung 18650 30q (I know this because I was told). I am looking at buying another pair of batteries to keep in rotation, but I was just wondering what the difference is between them ? I know the 18650 is the measurements, but I don't know what for example a Samsung 18650 25R means. Any help?
Thank you
