Well i can remember something just like this happening with cordless drill,then they using ni-cd batts and they were heavier then todays ni-mh packs, last i remember there was talk of a 24v cordless drill and i was thinking : whats next a car batt pack ?!?!? i stopped at the 12volt mark ,just as fast as the 18volt and a lot easier to fit in my bags
with that being said:
locally there is a modder making custom boxes that go from 300 watt all the way up to 3400 watts [no that was not a typo] ,and no i won't tell who it is either !!! i will not be involved with somebody removing their dam head because they wanted to vape with the biggest and baddest mod around
