Hello! A lot of vapers who I know, think that notebook-like or powerbank battery is very bad for vaping. They say that it can explode, wery weak, etc. Those battery has about 5 amperes discharge, so, one battery can gives about 15w when voltage is 3. Do I have abything wrong if I use it in parallel-battery mod (istick 100w TC) if my maximum wattage is about 25?
