DCB546-XJ 18/54 Volt XR FlexVolt 6Ah Battery Pack

The DeWALT XR FlexVolt 18/54V 6.0Ah Battery represents the next generation of cordless power for professional construction and site work. As the world’s first convertible 18V / 54V battery, FlexVolt automatically switches voltage depending on the tool, delivering exceptional power for heavy-duty applications while remaining fully compatible with existing DeWALT XR equipment.

In 18V mode, the battery provides market-leading runtime, making it ideal for drills, impact drivers and everyday XR tools. When used with 54V FlexVolt tools, the voltage steps up to deliver the power required for demanding equipment such as large saws, grinders and construction tools — without the restrictions of cords or generators.

Completely backwards compatible with all DeWALT XR 18V tools and chargers, this battery allows tradespeople to upgrade power output without replacing existing equipment. Built with advanced lithium-ion technology, it’s designed to withstand the demands of professional use on busy sites.

A reliable choice for contractors, plant operators, carpenters and fit-out teams who need corded-level performance in a cordless platform.
