You probably don't have enough posts to post a link yet, you're too new. So, why don't you explain your problem again?

Just to help you out, here's your other thread, though I don't see the images you tried to post there:
Hi everyone!!

Dear forum,
I'm Colosea from Bergamo (Italy) and I'm new in this forum because I'm triying to design a e-cigarette by myself. I have now a problem with the battery and his protection
Here you can find a picture from my design
(SEE BELOW)
The problem is when I plug the battery nothing happens, no voltage flow, but if I touch the VBAT- with GND of my PCB for a instant, the voltage is OK all the time.

Any engineer can help me? any idea are welcome!

Yes! this is the circuit and my ask

Looks all screwed up.
Why not follow the application notes of the chip?
