Hey everyone, just a quick question. So I was given a CLRD NCA18650-E28 2800mah 35amp high drain 18650 battery the other day by my uncle to use in my KBOX Nano. it seems like it'd be a good battery to use assuming that the specs on it are correct. I was just wondering if these are safe to use? and also, if they are, what is the lowest ohm coil I could use safely?
