I've already got two DNA 200 mods on the way, honestly I have no will to get another mod that uses 18650's. LiPos offer more life, USB charging and have higher output potential than dual 18650's could ever offer. There's slightly more risk with lipos but unless you're not using common sense then you shouldn't ever have an issue.
Yea, that is nothing more than personal preference and unless you have had a few Lipo builds apart you have no idea the risk difference. Some are using 3/4 cells to deliver power.
Another consideration is while USB charging is handy for some, others would prefer to Swap and go rather than wait.
Overnight charging is a hazardous practice also with lipo's.
As for Dual or single. Dual gives you more time. Single gives you more room.
Both have advantages and disadvantages.
Personal Preferences
Whatever works...............For you.
