I just got a 510 Dual Coil tank cartomizer from Mad Vapes. I put it on my standard Ego batt and, after vaping about 20 minutes, i burned off the primer but my BIG problem is there's no throat hit. Is there a trick to filling and/or vaping these? I filled the tank about 1/2 full and primed the carto with about 10 drops. There's a lot of hissing and cracking sounds which i dont' mind as long as that doesn't indicate a problem. Does it take a while to break these things in (it's my first tank). It's 1.6ohm. Would i do better hooking it up to a vv batt? If so, what is highest voltage i could use before damaging it?
