Well, your battery info looks good! The kernel_task issue is caused by a sensor issue. Lets see if we can ID it using this app [https://www.tunabellysoftware.com/tgpro/|TG Pro] post a snapshot of the main window so we can see all of the sensors (you may need to grow the window)

The error you are seeing is: 4SNS TsOP - 124 - Palm Rest Temp sensor. You’ll need to inspect the trackpad connection on the logic board. Using a magnifier inspect the connects on the logic board and the cable you may have damaged one or two of them. If they are OK then the table its self or the trackpad are damaged.
