Our Opinion

Dewalt FlexVolt Technology

DEWALT DCK299D1T1 FLEXVOLT 60V MAX / 20V MAX Lithium-Ion XR Brushless Hammerdrill and Impact Combo KitYou can always trust Dewalt to make quality power tools, and this innovation in their batteries is impressive. The Dewalt FlexVolt Technology enables the batteries to change its voltage when used in different tools. The 20V Max batteries can be used for all tools that run on 20V, 60V, and 120V. Basically, the tools let the battery know how much power it needs and it automatically changes its mode.

If you use these batteries on a 20V Max tool, you will get more runtime for that tool. For 60V and 120V Max tools, it has enough power to operate those, too, but with limited operating hours. This will make it easier for completing jobs that need different tools with different power consumptions.
