DCB548-XJ, 54V Flexvolt Battery, 12.0AH

Features: Revolutionary dual-voltage technology automatically switches between 18V (for maximum runtime in XR tools) and 54V (for corded-like power in FLEXVOLT tools); LED fuel gauge (3-LED State of Charge indicator) for real-time charge level monitoring; rugged, impact-resistant housing with over-molded rubber for drop protection and durability on job sites; intelligent cell balancing, thermal management, and protection electronics for extended life, safety, and performance; uses 22mm high-capacity battery cells delivering 216 Wh of energy for longer runtime without increasing size or weight (same footprint as the 9Ah DCB547); compatible with all DEWALT XR chargers (e.g., DCB118) for fast charging; no memory effect typical of Li-Ion chemistry; backward compatible with existing 18V XR ecosystem while enabling high-power applications
