The DeWALT 18 V XR starter kit 2x compact powerstack battery packs and charger enabling faster application speeds and increased productivity with a 25 percent smaller
footprint with its compact design, the powerstack battery is compatible with all the 18 V XR tools you already have and the stacked pouch cell technology benefits from superior thermal performance ensuring increased recharge cycles and improved battery durability, its innovative design ensures an impact-resistant, overmolded base with non-marring material whilst being 12 percent lighter.

The stacked pouch cell battery technology provides a low impedance construction meaning that the rate of flow of electrons is much higher
A low impedance construction translates into much higher max watts out, providing more power to your power tools and unlocking the 18 V power tool potential
Stacked pouch cell batteries also benefit from superior thermal performance vs cylindrical batteries
This ultimately increases battery durability, improves the cycle life and results in a much greater return on investment for your kit
