DEWALT PowerStack 5Ah With DCS570 Circular Saw Kit Review DCS570H1

[@chetfriday7636]

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.

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 🙂

Now I think an amazing comparison to do would be between the "Power Detect" saw DCS574W1 (8ah) vs the 5ah Power Stack saw (DCS570)!!! Which gives you more increased performance, the "power detect" or the "power stack"??

[@kieranlavoie8124]

This saw made me buy 9ah flexvolt betteries. Though when i need it to be compact i use the powerstack every time!

[@jimwhite9483]

I remember the look on my dad's face when I mentioned that I had cut the plywood three times already and it was still too short.

Nice. Definitely the video im looking for this holiday

[@texasproud975]

For price I just stick with the XR batteries they do fine for me. Maybe when powerstack prices come down I’ll change.

[@hewlett260]

Seeing this test makes me happy i went with the dcs578 flexvolt saw. The 20v max saw just don't have the power and they all sound like they struggle while the flexvolt seems to outpace most corded saws

Very thorough, thank you 🇦🇺

You should do some tests with dewalt’s 10 ah battery

[@skliros9235]

Why? It's an oddball battery, not widely used

[@parkerk7018]

@@skliros9235 it’s an underrated battery

Merry Christmas. I guess I'm sticking to the 9 amp

Maybe Santa will give you a 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.

[@BigZ971]

I work in a cold storage building (-15F). And those Milwaukee batteries do not last in there at all. But that's just the nature of battery technology. Hard to create an electrical potential difference at such cold temperatures. Dewalt is going to do the exact same. We have to leave our impacts out of the freezer when we are doing repairs and only grab them the moment they are needed. Otherwise they just won't work.

[@puukkoallu333]

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.

[@WorkshopAddict]

That was the original plan, but the saw was not cooperating. I am pushing these saws a bit and not having great luck with them holding up to some of these tests. I need to find a better way to find 50% charged and i will be going back at this test with a new saw.

[@jacksmith2315]

@@WorkshopAddict maybe try them on a different tool like impact wrench or chainsaw

@jack smith have both of those videos up!

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 🤞

[@WorkshopAddict]

I am sure warranty will work. If it is within 90 days, you can return it to the store and get a new one. The 9 ah fv is one of the better batteries out there.

[@loucifer4205]

If you drain the battery to it's completely dead that's a no no but you can bring it back there are videos on KZbin showing you

[@wim0104]

big batts have more cells, one bad cell takes down the whole batt; it's a numbers game. I had to RMA a 6AH M12 this year.

[@The_Big_G]

It's charging to 18 volts and kicking off the charger like it's fully charged, two bars on battery. I definitely need it, just not often I have to run the 9ah as far as power demand. If I have to I'll purchase another one, definitely should get warrantied but beyond 90 days, believe I bought it in March. I normally run powerstack 1.7 or 6ah on occasion 9ah, your testing has confirmed what I assumed from real world use.

[@qqslp]

For what it's worth, I've been heavily using 3 flexvolt 9ahs for around 2 years and they are all still good.
