Hey, there!
I've had this thing for many months, and it has worked more easily with my tanks (EVOD2) than branded batteries like the EVOD, JoyeTech, and Vapor Tech. This is DEFINITELY because I've just had bad luck, and I've grown attached to this small green tube I use to power my vaping. However, when plugged in, the battery will claim to be charged when it is not. Check this picture out:

1) The battery is a 3.7v, which I can easily buy anywhere. 2) There is a chip under the button inside of the tube. So the question is, is the charging issue more likely to do with the chip or the battery?
I ask because I have experience building batteries from individual cells for airsoft guns and RC toys, but only at the most basic level. If the problem is more likely the battery, I want to buy a new one, wire it, and fire it up. If the problem is the chip then, well, I'll continue to search for a battery that works for me.
What do you think?
