Apocalyptech by Aelfwynn on Ao3.
I started this story in November 2021. I stopped at Chapter 11 in June 2022 for various reasons. I finally came back to it with Chapter 12 back in February 2026, and have been faithfully adding chapters since. Chapter 20 newly released. If you want a sad Tech/Bad Batch story with mystery and hope thrown in, this might be it:
Ten years after Order 66.
Tech is on his own, not only fighting the Empire, but fighting himself.
His entire world has crumbled and now he searches for a reason to go on.
