These are quite common in 18V cordless tool packs where there is a small version with only 5 cells (1P).

If you are working all day with the tool overhead (like drywall on the ceiling), then I'd want the battery to be as light as possible, even if it meant that I needed several packs to keep one runnable at any given time (with several chargers topping off the stand-by's). 2000-mAh is short running time, but it is a small price to pay to have high amps in a small package.

The 2P / 10-cell 18V packs often have 30Q cells, since 2P of the 15A cells can provide 30A, so...twice the weight provides three times the run time.
 
My charger just took this to 4.35V per cell in a kobalt drill pack 6S1P I was expecting 25.2 and I got 26.1 before cutoff of bms. Is there another version of the same cell or is my charger intentionally over charging the cells?
 
Probably the c

Probably the cells were still draining current so that's why they were over-charged.

That was what I thought, but they have been at 4.35 since i made the post, even with me randomly hitting the button to check the SoC... i figured even that little set of LEDs might have some effect but nope. Not one. I may grab an x6 and do a capacity check in a week or so and see if they come out to 2k+-

No, tool battery chargers usually cut off before 4.2v, so either your multimeter is broken or your charger is
 
10 of these are found in DeWalt 20v XR Battery, with a number of them still good. Pack number DCB204, I've found both these Samsung Cells and the LG LGAAHD21865 under the same battery pack number.
