Hey there. First time posting. I've been told those are both good batteries. Do you agree? Why should i buy 5 instead of 6? Isnt 6 the latest "model" ? Im just a regular guy vaping 50-90 watts throughout the day. What are your recommendations for that kind of vaping? I want them to last long and maintain power. Ps: vaping exclusively on a regulated mod. Thanks guys and gals!
