When I removed all the screws and the triangular cover too, I tried removing the bottom cover but it felt like it wouldn’t come off. If I put in too much force, it felt like it would snap.

Hi @durrdurr25 , Here’s the ifixit ASUS ROG Strix GL503VD-DB71 Battery Replacement guide. It is useful as it shows how to remove the back cover from the laptop. Did you remove the screw below the removable panel as well?
