The DEWALT FLEXVOLT DCB606-2 automatically changes voltage when you change tools, seamlessly powering 60V MAX and 120V MAX tools while remaining fully backward compatible with your existing 20V MAX tools and chargers — delivering the power of corded with the freedom of cordless.
Each 6.0Ah battery pack delivers 4x the runtime of the DCB201 1.5Ah battery and 3x the power of the DC9096 18V battery, with built-in intelligence that knows when to supply runtime for 20V MAX tools (6.0Ah) and raw power for 60V MAX and 120V MAX applications. Sold as a convenient 2-pack.
