[Tim_]

Hi,
So 2 weeks ago I builded an okl t20 box mod following this tutorial:
How to Build OKL T20 Box Mod Tutorial - FindMyVapes
--------------------
This is the diagram:

And this is my box :

I use two 3.7v batteries (2200 mAh). But my box doesn's work...
I use a multimeter, and he say, that there is power (6.89v). So I don't understand wy. I use a tsunami rda, and he work on a friend's box.

Does enyone help me?

Thank you very much
Tim

Would help if we could see everything. What mosfet did you use? What is the amp rating of those batteries?
