I've been looking into how flexvolt batteries work, specifically how their runtime stacks up against standard 20V batteries. Since flexvolt batteries can be used with 20V tools, I'm curious about how a 6AH flexvolt battery's runtime compares to that of a 6AH XR battery. Theoretically, I thought it would offer about three times the runtime, but I'm seeking some practical insights on this. Any thoughts? Thanks!

That's an interesting point! I wasn't aware that flexvolt batteries only match the XR runtime when used at 20V. Good to know that flexibility is useful, but for 20V applications, performance is pretty equivalent.
When using a 6AH flexvolt battery in a 20V tool, you'll find that it actually has roughly the same runtime as a 6AH XR battery. This is because flexvolt batteries are rated at their 20V capacity—so a 6AH flexvolt is indeed rated for 6AH at 20V, but it's 2AH when at 60V. So, you shouldn't expect a huge difference in runtime here.
