creating a hot patch SSDT for my battery status

I have a fully working battery status with a statically patched DSDT but would like to change this into a SSDT.

I already got the necessary SSDT and it's kind of working, the only problem I'm facing is the embedded controller field in this SSDT. If I just copy paste the whole patched field from the DSDT it works but expectedly I now get ACPI errors during boot because the EC field is duplicate.

I exactly followed rehabmans guide to create the hot patch, but when I insert the EC field in the SSDT as he explains with the offsets correct and everything the battery status just won't work and at this point I don't know why or what's wrong.

Below is my patched and original DSDT and the (atm) not working SSDT, with the EC field as described in rehabmans guide
