HI and welcome. Sigelei is a pretty good brand name; I'm not surprised you're getting it warrantied. If I were picking a new, two-battery mod right now, I'd probably lean toward a Sinuous Predator 228. I have one and I like it. (There are, of course, many others, but I was leaning toward the "reasonable quality, don't break the bank" type). I am also very fond of the Reuleaux RX200, but this is a three-battery mod. They have others, like the 2/3, which can be rigged for 2 or 3 batteries, but I don't have one so I can't comment. Neither do I know much about pre-fab coil
tanks as I have wound my own coils for years. I do know the various "Beast"
tanks from Smok are well thought of in that area, despite being allergic to trying one. One caveat: if you ever intend, or want to try, coil building, the Beast
tanks have an RBA that is alleged to be finicky to build on and would therefore not be a good place to start learning. As to batteries, I below append
@Mooch 's chart, so you an see what batteries he recommends. I personally lean toward the LG HD2Cs or the HE4s. Other good choices are the Sony VTC5, VTC5A and VTC6, or the Samsung 25R or 30Q cells.
