Dewalt DCBP518 Powerstack Features Higher max watts out, so there's a greater range of applications Faster speed of application, giving you increased output and more jobs done Improved thermal performance. Pouch cells run cooler in application and dissipate heat better than cylindrical cells Create less heat resistance which means fewer hot pack shutdowns meaning less downtime and more productivity Increased cycle life, which means better performance for longer Fully backwards compatible with all Dewalt XR 18v Tools How do Dewalt DCBP518 5.0ah Powerstack deliver more power? Pouch cells run cooler in application because of their lower resistance. As a result of their increased surface area, heat also dissipates better than cylindrical cells. Less heat build-up means fewer hot pack shutdowns and less downtime. How do Dewalt DCBP518 5.0ah Powerstack offer a longer life? When batteries are charged and discharged, their useful capacity decreases, the cell's internal resistance increases resulting in more heat build-up and less available current to power your tools. The capacity loss in the Li-Ion pouch cells used in POWERSTACK batt
