Battery Full [Q] Help me remove the battery icon?

I am currently running this ROM and I'm trying to add battery percentage near the battery icon. I tried using an xposed module called GravityBox, and it has an exact battery icon with percentage as in my ROM. But the problem is, whenever I apply that icon, seconds later the original stock battery icon shows too and I have two battery icons on my statusbar.

I tried many other xposed modules that are known to remove the stock icon, but none of them work.
Is there any other easier way to add percentage to the left of the battery icon? Would deleting the battery .png images from systemUI work?

PS: The ROM has an option to add percentage, but not the way I want it. It has the percentage inside the battery icon.
