When I tested the feel in my DCD998 Hammer Drill, initially I felt like I needed more weight in the battery in order to balance the tool to my comfort.
DEWALT BATTERIES POWER STACK DRIVER
It provided good balance and no bulk in my Flashlight, impact driver or oscillating tool. As I started testing in several tools I found it to be very comfortably balanced in the smaller, lighter tools. The battery is 1/2" shorter and narrower than my DCB203 and definitely lighter. After I received the kit I immediately noticed the size and weight difference. I'll definitely be filling my Toughsystem battery box with a few more of these. I am excited about this new technology, and can't wait to see it applied to the Flexvolt batteries to reduce their weight, or even a 20v 4ah Powerstack battery. It cut plywood no problem with the circ saw, and even runs the big hammer drill (DCD999) in a pinch.

I also couldn't resist trying it on bigger tools and it really impressed me. Compared to the DCB230 battery I usually run on the sander, the Powerstack battery is about half the size and less than half the weight. This battery was really comfortable on the 20v sander (DCW200) as well, with the reduced weight and improved balance, it was more ergonomic during extended use. I try not to run batteries all the way down to make them last, so when it hits one bar, throw it on the charger.

This was a heavy application and the battery delivered incredible power!! It cut almost 20 linear feet before needing a charge, which is incredibly impressive for its size and the extreme cold. I was using my oscillating tool in a pinch, with a diamond grout blade. I later ran the Powerstack battery outside, cutting cement backer board in very cold weather. In those cases I like the 3ah with the 21700 cells. The only drawback one might consider, is with an oscillating tool or a similar tool where you want the larger battery case to help it stand up. It charges very quickly on the fast charger as well, so two of these batteries will keep your impact going all day long. This is great for lighter weight on the tool bag, and the Powerstack delivered consistent power. I like running the small batteries for weight, and compared to the other 20v 2ah and 3ah batteries, this unit has such a small footprint! In many cases it's slightly smaller than the base of the tool. One day I used it for framing with my 20v impact (DCF887) to run 3" deck screws, and it lasted for over 4 hours of heavy use. It is incredibly small and lightweight, it almost feels like a toy compared to the DCB203. This little battery really packs a punch! I received this battery right before Christmas, and used it on many different jobsites.
