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.

The datasheet lists a rapid charge at 4A is possible.

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 36V 6AH (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.
