These are cells found in the Aldi supermarket's "Xfinity" brand 20v 4AH tool battery packs, as sold in Australia in late 2018.

Edit to add: The Aldi packs are marked slightly differently, with "SDI <new line> IG3T" rather than the "SDIEM", as seen above. They're also a greener in colour.
 
Found these cells in Hilti Cordless tool batteries B22/5.2. 21.6v 5.2AH

It was very difficult to liberate them from the holders. Damaged the shrink on almost every cell.

You're thinking of the "25R" that come from the B22/5.2AH packs(6s2p), . The 20Q are found in the larger 36V6AH (10s3p) packs... which are now sold with the VTC6 cells for a whopping 9AH.. woot.

The B22/5.2 contain either VTC5(a), 25R or some LG yellow shrunk wrapped cells! very rare those ones tho.. must have been only a few batches of those about.

The predecessor (pre 2016ish) was a smaller pack with VTC2 cells, and before that the VTC1 cells.
 
That’s a crazy low voltage EOD limit. So if my tester only takes them down to 2.59v could that be the reason I’m only getting 1900 mah out of them?

I wouldn't take that as a low voltage limit if you want the cells to live a long life. It has such a low value because it's designed for very high discharge rate. It shouldn't be the reason you're getting less capacity, my tester with 2.75V cutoff yields nearly 2AH on these cells.

Yea they come out at like 1947 one one and like 1922 and another at 1993 or 1935 none above 2k but pretty close I’m not mad I’m after 75% or higher and these are around that when testing so idk what I’ll do just yet this is my first pwall
 
A lot of top power tool brans used these cells. In the last a few years they generally switched to Rs.
