Testing the DeWalt DCS 570 with Different Batteries
DeWalt has released the powerstack 5.0 amp hour battery along with a range of tools, and one of them is the DeWalt DCS 570. We conducted a test to run the 5 amp hour XR all the way up to the 9 amp hour Flex Volt, and observe the voltage sag with each battery.
Test Methodology
We conducted three cuts with each battery, and moved the guide in between each cut to allow the battery to stabilize. After three cuts with each battery, we drained the power stack battery down to approximately 50% using a heat gun, which we tested in a previous video. Then, we ran three or four more cuts with the saw to see how the battery holds up after it has been drained.
Battery Performance
The 5 amp hour XR battery performs well, but it dips down quickly into the 16s and even the 15s, which is where the bottom half of the power stack battery ended up. The bottom half of the power stack battery acts like the top half of the XR 5 amp hour battery, which is interesting. The 6 amp hour battery outplayed the 8 amp hour battery in most of the higher demand tasks. As we moved up into the batteries, we could observe a huge difference in speed and performance.
The power stack 5 amp hour battery held up in voltage mostly comparable to the Flex Volt 9 amp hour battery. Although the power stack battery did end quite quickly, it did go down with good results. We tried to use it again, but it wasn’t going to work. We threw it back on the heat gun just to check the voltage, and it was dropping quickly. The power stack battery worked best with circular saws, providing good results on a smaller battery that most people typically use.
Conclusion
The power stack battery is a good combination with the DCS 570, and putting this battery with something that needs or wants a higher draw seems to work out. If you are looking to purchase this battery, it may cost more, but it provides more information to make an informed judgment call. The kit with the power stack amp battery and the DCS 570 is coming out soon, and we hope that the prices are reasonable.
We hope this information will be helpful for you to make a decision on whether to buy this product. If you have any comments or feedback, please share them in the comments section below. Don’t forget to give us a like and subscribe to our channel for more videos like this one.

5ah 🔥
Would have been nice to see how the 6ah battery would perfom in the cutting test after draining it to 50% to get better refference to powerstack.
As a DeWalt fan, I can honestly say that the Powerstack batteries are a total disappointment and they are well over priced. We have endured weeks of -60 degree snowy and windy weather in Montana and these batteries out on the job work in slow motion the colder they get. When they are put into real work jobsites, they fail totally. I had to grab out the Milwaukee tools and batteries in the truck that had been staying for weeks and they did just fine, didn't even notice the cold temps.
Bring your truck of OSB outside in the mountain region cold, leave the batteries in the truck over night and then test them. You will be shocked when Powerstack fails.
Very thorough, thank you 🇦🇺
Great in-depth testing again. Currently the only batteries i have are both of the PowerStacks (1.7 and 5Ah). And merry Christmas!
You should do some tests with dewalt’s 10 ah battery
I keep thinking in simplistic terms… bottom line is how much energy is delivered from the powerstack 5ah vs the older 5ah battery. Dewalt says "50%" more power with the 5ah powerstack. The only way that that could be true would be if they are differentiating between potential energy and delivered energy. Based on what I have seen, the average Joe needs to know that the powerstack will (1) last twice as long in terms of the number of charges, (2) do about 20% more work than the older 5ah battery, and (3) deliver more volts to applications requiring more power. But it is (1) bigger than the old 5ah battery, (2) more expensive, and (3) the older battery may be satisfactory in meeting the needs of the weekend warriors who buy most of these tools anyway.
It would be so much easier if the marketing folks of these power tool companies would just come clean and deliver clear battery performance specifications – but then they probably wouldn't be able to sell as many new batteries.
Merry Christmas. I guess I'm sticking to the 9 amp
Another good video nice job, Merry Christmas
you make some excellent points, and again it's good to see that the new tech holds its own.
I went for 2/6Ah FlexVolt 60V (because 60V chainsaw) and MetaboHPT 40V with free 4/8Ah batts (for circ saws).
Maybe I won't feel so smart once 60V PowerStack (2.7Ah *3 = 8.1Ah ?) comes out 🙂
My flex volt 9ah just died on me after using it maybe 6 times. Very disappointed, bout to warranty it and see how that goes 🤞
