Dewalt batteries power stack drivers#
However, impact drivers are short-burst power tools. 10 x three-inch structural screws with a vengeance. With the battery, the tool weighs only 2.6 pounds, but it drove No. We were impressed when we used the battery in DeWalt’s new ultra-compact DCF850 impact driver. According to DeWalt, the sum of these features make pouch cells run cooler and produce less waste heat per unit of electrical output and in doing so this makes them more efficient at converting electrochemical energy into electrical energy than batteries with cylindrical cells.ĭeWalt’s illustration of Powerstack next to its existing lithium-ion DCB203 battery. You can also solder these cells together in a manner where if once cell fails, the battery continues to operate. Fewer soldered connections increase reliability since there are fewer connections to fail. Second, the cells are simpler and require fewer soldered connections. First, there's less wasted space between cells, so you can pack more power-producing battery into a given unit of space. You can take that flattened battery and fold it into a pillow-shaped pouch (or other shape) if you wanted. To visualize this, picture unwrapping the layers of a cylindrical lithium ion battery and pressing them flat. The Powerstack uses a form of lithium ion battery with cells shaped like flat pouches, rather than cylinders. It’s expensive when compared to the company’s existing lithiom-ion batteries, but DeWalt managed to make it smaller and lighter while churning out power comparable to that of a corded tool. And after our testing, we can vouch for the platform. DeWalt has seemingly solved this with the introduction of its Powerstack battery system (which goes on sale next month). In so doing, brands can rob their tool of the nimble quality that was supposed to come without a cord attached to a 120-volt outlet.
It can help you achieve more satisfaction from the job and stay safer, and it may even improve your workmanship.īut PTW will suffer if a cordless tool, and its battery, is made too big in an effort to compete with the power of a similar corded model. But it’s also a big deal if you’re just a homeowner working on your own place.
A tool that’s less tiring to use is one that’s safer.
A favorable PTW ratio is also a limb-saver if you’re holding a power tool over your head or working with it at the end of a fully extended arm for any period of time. Tools with a higher PTW are more productive, and-in the construction trades-that can translate to more income because you may get more done in a day’s work. But that can often come at the cost of power, so the power-to-weight (PTW) ratio is a handy gauge of how much oomph they pack into their smaller frames.
Dewalt batteries power stack portable#
Much of the benefit of battery-powered tools comes down to how much more portable and nimble they are than their corded brethren.
