  • Our take on the DEWALT 20V MAX POWERSTACK Compact Battery (DCBP034)

    The DeWalt 20V MAX POWERSTACK Compact Battery (DCBP034) is a 20V lithium-ion pack built with pouch cells instead of standard cylindrical cells. DeWalt claims 50% more power in a 25% smaller footprint, twice the cycle life, and it is the lightest pack in the line. It fits every DeWalt 20V MAX tool and charger, so it works as a drop-in upgrade for owners already in the system. Against DeWalt's own 2.0Ah cylindrical packs it is smaller and stronger but holds less charge, so it suits drills, drivers and light cutting more than long runtime jobs. Owners rate it highly for size and power; the common complaint is short runtime and a higher cost per amp-hour than bigger packs.
