New Tabless Cell 5Ah XR to Replace Pouch Cell 5Ah PowerStack

DeWalt is currently holding an influencer invite showcase event, similar to what Milwaukee does with their Pipeline (formerly NPS) event, and they revealed a new 5Ah XR battery. From as far as I can tell it is 18650 cells, so it will be the same size as venerable standard 5Ah DCB205, but offer power more like the larger 21700 based 6Ah/8Ahof years past.

It also is slated to replace the PowerStack 5ah DCBP520, which has always been a bit of an odd duck. From its early revs having premature failure issues, to its size just not being all that compact. PowerStack shines in compact batteries, the 1.7Ah and 3.5Ah are amazing, two of my favorite batteries.

The use of tabless 2500mAh 18650 means an update to the FlexVolt 15Ah is also a possibility, though I'd rather see a 15 cell 21700 15Ah just for size sake. Or maybe a "compact" 7.5Ah FlexVolt that is the same size as the current 6Ah FV. So many options.

All sorta speculation at this point, but just be prepare for more confusion of their ever evolving battery line. And for clarification I was not there so I can't really answer any questions, but just wanted to share.
