I am wondering what the consensus is about what the safest, best performing battery is for mechanical mods? I read around here some and seem to run into some conflicting opinions, is there a consensus? This may be a common thread, so apologies in advance. Heres the deal - I recently acquired a mechanical mod with three tubes (18350, 18500, 18650) and wonder what the absolute best battery I can buy in each size for it is? It will be used with something in the 1.5ohm range on top of it (no sub-ohm stuff). Keys here are safety and performance (I guess this might be a balancing act of sorts, but I have listed safety first), money is not a factor... I want to buy a pair of each size battery mentioned - so they should be currently available - again, price is not a concern - I understand each size may well be a different brand - please help. Thank you!!
