Thinkpad T450 using OC - No battery, no audio how to fix?

Hey guys,

I have a question regarding the Thinkpad T450 mentioned above. It's currently running macOS Catalina 10.15.7 as a MacBook Pro early 2015, but with said problems. Except for that, everything seems to be working fine as far as I know (I haven't tested it extensively, since I build it because of said issues).

Here are my basic stats first:

Processor: Intel i5 5300 U

RAM: 12 GB

Graphics: Intel HD 5500

Battery: Two battery (so inbuild + the large removable one)

Opencore Version: 0.6.0

Below you find the EFI I currently have:

(Made using the official guide as far as I can remember)
