I've got a bunch of Dewalt tools, but I've always stuck with the batteries that came with them. I'm wondering which Dewalt 20V batteries are the best to use? Any recommendations based on performance or longevity would be super helpful!

For power-heavy tools like grinders or saws, I hear the Power Stack is the way to go. If you’re using something that runs longer, like vacuums or blowers, the Power Pack might be better. Personally, I use a Power Pack for my handheld router since I'm not doing any heavy-duty work with it. I’ve also seen someone mention that the 8Ah Power Pack has different cells for higher currents, which sounds promising!
Battery voltage is pretty standard across the board—if it says 20V, it’s always 20V. The quality comes into play when you're using tools with different voltage options, like the Flexvolt, which can handle both 20V and 60V. The Power Stack batteries are designed to last longer thanks to their unique cell arrangement.
It really depends on what you need! A 1.5Ah battery is not going to cut it for string trimming, but if you're just drilling a few holes, a Flexvolt 15Ah might be overkill. Just choose based on the tool you're using!

Really appreciate it, this helps a lot!
