In the world of cordless power tools, DeWalt's FlexVolt platform revolutionizes how professionals and serious DIY enthusiasts power their gear. These innovative batteries automatically adjust from 20V MAX for lighter tasks to 60V MAX for heavy-duty applications like cutting thick lumber or drilling through concrete. This dual-voltage tech means one battery powers over 100 compatible tools, from compact drills to massive circular saws, saving you time, space, and money on multiple battery systems.
We've tested FlexVolt extensively in real-world scenarios—framing houses, renovating workshops, and tackling garden projects. Our overall platform score: 8.2/10. It shines in power delivery (9.5/10) and compatibility (9/10), but higher weight and cost dock a few points. If you're upgrading your toolkit, FlexVolt is a game-changer for efficiency. Ready to dive in? Let's compare the top batteries first.
Here's a side-by-side look at key FlexVolt batteries based on capacity, performance metrics, and practical use. Data from lab tests and field trials (runtime measured on a 60V circular saw cutting 2x10 oak; charge times with standard DeWalt chargers).
