hello ecf, just wondering other then the mah what is the better out of the two? According to the chart @Mooch created the vtc4s are better from what I understand of it. Need to buy at least 3 for my rx200. Already have vtc4s for my mech mods but they only take two at a time. Anyway just curious on people's thoughts on which to get and why? Battery life wouldn't bother me as I can charge from the device. I would like to be able to vape at 200w eventually and the temp control wouldn't bother me I don't think. Thanks in advance
