Batteries just a little too big... Possible Hazzard

[MrKrinkle]

Two of these:

or two AW IMR 18650:

what about the AW IC version of the CR123 can they be stacked as well???

and that's hot doubles as a baton in case you run into any trouble while your vaping... lol

ok well I am now the proud soon to be owner of 2-AW IMR 18650 1600mAh & 2-AW IMR 16340 550 mAh batts and a new charger because I found my old Ultrafire WF-139 was not a good charger for this type of battery.... Thank you everybody for your help and advice always appreciated...
