Dewalt DCBP518 5ah Powerstack Battery Powerstack batteries which are special because they use the pouch cells, much like those in mobile devices like phones, laptops, drones and more. These are a huge upgrade over the ordinary XR battery packs which contain either 18650 cells or 21700 cells, both of which are cylindrical. Even when packed into the most efficient arrangement (hexagon positioning), there is still much wasted space between each of the cells. The DCBP518 5.0Ah PowerStack battery (and previous compact version) solves this by using flat pouch cells, essentially cuboid shapes. These have no wasted space between cells, and minimal wasted space between them and the battery housing. FEATURES: Delivers unparalleled performance and runtime from a 5Ah Pack Pouch Cells allow for higher current draw and performance vs traditional cylindrical cells Intelligent Battery Management System monitors and protects battery State of Charge (SOC) Indicator Industry first use of 18V Pouch Cell Technology Offers 2 x Lifespan vs. DCB184 5Ah cylindrical cell battery Provides up to 2X runtime in demanding applications vs. DCB184 5Ah cylindrical cell battery 750 grams
