DCB547-XJ, 54V Flexvolt Battery, 9.0AH

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 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; compatible with all DEWALT XR chargers (e.g., DCB118) for fast charging; high-capacity cells deliver exceptional runtime and power density; no memory effect typical of Li-Ion chemistry; same footprint as standard 18V XR packs (minimal added height) for easy integration
