FlexVolt batteries switch voltage automatically: they run 20V MAX tools at 20V and 60V MAX tools at 60V. One FlexVolt pack can cover both systems, and two together power 120V MAX tools.
Common tools: 60V FLEXVOLT circular saw, 60V chainsaw, 120V MAX miter saw, 20V MAX tools (step-down)

FlexVolt is backward compatible into the 20V MAX system, but standard 20V MAX batteries do NOT run 60V tools. FlexVolt does not cross to other brands.
