it doesn't matter what you use for accordition, content is not full width
because visual composer adds margins and paddings for rows and columns.
Accordition is full width, but content is not

This is not working because I'm not using page builder's Accordion. 

I'm using s-button's Accordion.

Can you tell me any trick to show it full width on mobile devices.

I'm not using builder's Accordion because its title - H1. I don't want to use H1 titles. So I'm using s-button. 

You used Visual composer inside desciption field. So, you can control
margins and padding of each row inside options of row. I don't recommend to
use VC in text. You can use our shortcode generator instead (button S near
media button)

I can't help without direct link
