The DeWalt DCB2108 is a 20V MAX XR lithium-ion battery pack rated at 8.0Ah, the largest capacity in DeWalt's 20V MAX line. It uses pouch cells rather than cylindrical ones, which DeWalt says delivers 50% more power and a longer lifespan than its traditional cylindrical packs. It suits owners of DeWalt 20V MAX tools who run high-draw equipment like circular saws, grinders and reciprocating saws for long stretches, and who want fewer battery swaps. Against the 5.0Ah XR pack it replaces, it trades added weight and bulk for more runtime and output; it is heavier than the compact 2.0Ah and 4.0Ah packs, so it is a poor fit for drills used overhead or in tight spaces.
