The FLEXVOLT® battery is backwards compatible with our 20V MAX* tools so you get up to 4x the runtime**. And because the FLEXVOLT® battery is the only battery that automatically changes voltages when you change tools, you can slide the battery into a whole new lineup of 60V MAX* and 120V MAX* tools from DEWALT.
The highly innovative FLEXVOLT® battery can power our 20V MAX* tools plus an all-new lineup of groundbreaking 60V MAX* and 120V MAX* tools. This is the power that will change everything.
