The DEWALT FLEXVOLT® 20/60V Max Power Tool Battery Pack is the most powerful battery in the DEWALT cordless lineup, boasting an impressive 15.0Ah capacity. What makes it stand out is its ability to automatically switch voltage between 20V Max, 60V Max, and even 120V Max tools, so you get the right power no matter what you’re using. It provides longer runtime for 20V Max tools and strong, cordless performance for 60V Max tools. The built-in 3-LED fuel gauge makes it easy to check your battery level at a glance. Plus, it’s built tough to work in harsh conditions—even in temperatures as low as 0°F—so it’s perfect for outdoor jobs in colder weather. Compatible with 20V Max chargers (sold separately), this battery pack is a smart choice for pros who need reliable, heavy-duty power across a range of tools.
