Got a datasheet for a Great Power 60Q cell, they're claiming 60A true continuous discharge with a 110A temp limited discharge. does anyone here think they can actually achieve that in a 6000mAh cell?

unlikely this year in mass production. end 27 or later with decent cycle life.
The linkdata can approximately do that, so it doesn't seem audacious to have a higher discharge on a cell with a bit less capacity.

Thanks for the info about Great Power 60Q, It seems that it is already available at Alibaba. As far as I know, models such as the Reliance RS60, Tenpower 60XG, and Linkdata 60P cannot handle even a 40A continuous full discharge at room temperature without reaching the 80 °C limit.
Nelvick (Zeus_FL) has been testing the preproduction Trydan Tech 6000T, a 6.0ah 21700 which appears to be able to handle 45Amps continuous before hitting 80C.
Trydan Tech is an Indian based company with a 5000T cell as well.

Depends on how they qualify that rating.
It mentions “Not for cycle” so it might not be limited by the cell‘s general 80°C limit and is just a rating for bragging rights that’s incredibly abusive. A different company might not roll that way and choose a lower rating, one that would not exceed the cell’s max temp limit.
The market for these cells is brutal and I’m not assuming anything is off the table for the marketing teams trying to differentiate their cells from the competition.

I did a little research, and the Amprius INR21700/60Q should also be available. Unless something has changed, the Amprius 60Q and Great Power 60Q should be twins, both manufactured by Great Power in China, i.e. the same story as with the 50Q model.
As for Trydan Tech, its cells are also manufactured by a partner in China, and something tells me that Great Power might be that manufacturer as well. Well, at least that gives us testers a more work to do.
