HV Battery Recommendations?

Hey all, long time lurker here, first time poster.

I've read it quite a few times here, but now it's my time to shine!

After buying my car last year with 139,100 miles on it, it finally happened at 176,000 miles, the HV battery went dead. So sad.

Anyways, after getting Techstream set up on my computer, I read the codes to see only the P0A80 code with no subcodes. I got connected and retrieved the codes within a couple minutes, but by the time I turned the ignition off, the battery became so dead that not even the door locks would actuate, let alone start the ICE.

Here I am sitting at my computer now trying to research a good replacement for the battery for under $2K, is that possible? What companies would you recommend ordering from? And is it worth trying to get an "upgraded lithium battery"?

 

I had actually just emailed them and the representative told me that their container is stuck in the China ports due to Covid lockdown, says he hopes that they might be in by July.

Definitely interested in the lithium batteries, but not sure I want to own a ~2,000 lb brick till July lol.
