Okay, so you know the old saying..."a little bit of knowledge..."
Anyhow, I went down to the Shack and bought myself a 4AA battery holder with leads. I pulled the adapter end out of an old kr808 battery and soldered the red lead to the center hole and the black lead to the outer rim. I installed regular AA batteries in and didn't get a good vape. I then checked the soldering and installed 4AA rechargeable batteries. Vapes good now. Is there any harm in using these types of batteries? I really just wanted to test and see what a 4-5 volt was like. It seems more potent to me.

good start but it`s not enough.Why you don`t make or buy a variabile voltage and with two 14500 for this mod box
? With two battery you have a lot a space for electronics, switch and 510 connector
