There's your problem. You have to use 2 18650's. It's not a boost reg.

Not possible, first of all on that buck regulator you have to have 2.5 v more in than out, so your 3.7v would only be 1.2v coming out. You need two batteries in series for 7.4v in then you can regulate from 3 to 5,5v out. For what you want you need a boost regulator and that is another story.

What mod is this for? You can quite easily replace a 18650 with 2 smaller cells.

Or if you have one more 18650 you will have a long vape (battery)time.

If he had room for a 18650 he might be able to squeeze in a couple of '350's or 16340's. I hated to rain on his parade but he didn't believe me anyway, so.........how about a PTN 04050C
