Another vote for the Hello 016. i'm using LR attys that's suppose to drain the battery faster, but i can go all day and then some.
And for the price, why look at anything else??

The spare Hello battery i bought from Litecigusa is a tad longer than the Hello kit i bought from madvapes. And cheaper too.
