Pouch type LiPo cells (the type the PowerStack use, I believe) can usually deliver more current than cylindrical cells as they have lower internal resistance, due to the cell chemistry and the way the cells are designed. For two batteries of the same energy capacity rating (5Ah, 18/20V in this case), a pouch cell would be able to deliver higher current more efficiently (less energy wasted as heat in the battery, more power delivered to the tool). So when DeWalt claim "twice the power" they presumably are referring to that instantaneous power. For relatively modest loads, e.g. the vacuum, the current (power) delivery is fine for both battery types, so you get the same run time as they both contain the same energy: i.e. 5Ah x 18/20V.
No need to overthink it, they claim 50% more power and work and that's what you get. They have a lot of "not in application" caveats etc, but the bottom line is, for whatever reason, you get more work per charge when drilling or sawing.
Dewalts should start putting that rubber bottom on all their batteries, I use dewalt 5amp and flexvolt 6 and 9amp, they just seem to work well in most tools
Ha. Why would they do that when they can charge essentially twice as much for the PS and the "Oil Resistant" versions. But yeah, I agree, especially for setting tools down that rest on the battery.
Fantastic and practical comparison. Thanks for doing this! I've really been figuring out what to do for our heat gun and our big rotary hammer drill. The FlexVolt and PS seem to be the standouts. Very interesting about using Milwaukee batteries on Dewalt tools...never even considered that!
Great vid, all the stuff these days just seems so negligibly similar, particularly if you're low use or homeowner it doesn't matter. If you're in the trades just buy 3 high amp batters and there's not a thing to worry about.
Agreed. Most people I hear “fanboying” brands, are homeowners who will never use the tool to its true potential. I honestly believe that 99% of people just have tools that take a specific battery, so they jump on board and that’s it.
That was my fault with my power tools I started with rigid so I bought up all the three amp hour octanes I could find since they were discontinued and were the only batteries rigid offered with the 21700 cells. that pretty much is my go-to battery for everything impact driver drill 3-in cut off tool The only thing I go bigger on is the circular saw and the grinder as they are higher amp draw. I can get longer sustained power out of a higher amp power battery so those get six amp hours. Everything else gets a 3-amp or regular 4 amp hour battery
I don't know why this channel doesn't have many more subs. This is really cool. Technically decent descriptions and testing approach. This channel is out of the box better than 90% of other review channels on their best day. One addition: the reason why Milfuckee tools run better on Default batteries (or, any battery with a non-matching tool) is because the adapter doesn't have the thermistor pin connected as they have different values for each brand. So, unless the battery shuts itself down to prevent overheating, the tool won't do it.
Thanks, yeah supposedly the XC batteries protect themselves on whatever you run them on. That same test with that XC 5 on a Fuel 6.5” saw timed the battery out multiple times before the juice ran down. In this test the XC ran cooler on the Dewalt saw than the XR 5 amp. I doubt the XC runs that much cooler on the dewalt saw so leaning toward Redlink being overly protective. Which raises the question of why it’s not overly protective when used on the Dewalt. And your saying it’s the missing thermistor pin. If that answers that question the next I have is did the Xc shut itself down when the juice ran low to prevent over discharge or did DeWalt’s electronic protection system do it or both/either? For anyone not getting this we’re talking about the clip after the vid running an xc on the dewalt saw. That clip is from an upcoming non scientific method vid on batteries adapters.
@@toolrev I don't know enough about Mi or Dw internals to say if these tools all have battery protection inside, or just rely on the battery to protect itself. That would make an interesting test, i.e. discharge the battery with an external load and see if it shuts off or not. Risky though, the battery may be fried.
@@ericnichols9275so you are essentially overclocking the tools because you are driving them with a higher voltage than designed. Flex batteries have one more cell in series than 18v/20v brands.
Those power stacks really shine through in high torque tools that would otherwise stall out with smaller batteries- saws and drills using hole saws specifically. The 1.7 is light too for smaller applications like bandsaws or paired with atomic line tools.
Is the XR battery comparable to a lithium battery? I know nothing about tools and just want to get my man a really good battery. He's brought the dewalt lithiumbatteries up a lot just unsure what would be the better choice. Loved your review and testing. Thank you!
They’re all lithium ion batteries. Just the new “power stack” batteries use layered lithium pouches (like in your phone). The “older” batteries used cell batteries (like a bigger AA battery you put kids toy).. the new “power stack” batteries have better output wattage. Example 1.7amp power stack battery outputs at a 5amp cell battery level. But the 1.7amp power stack wont last as long because it is a smaller sized battery.
I'll take the compact power stack all day every day on an impact driver. No need to lug a huge battery all day long. Run time is not hindered because you can have multiple batteries charged and ready to go.
Thanks for doing this. I thought the PS 2.5 was supposed to be same as a 5Ah XR. My usage is on the small shop DW blower. And I still get more run time on the 5Ah XR batt. Main reasons I would see to buy the powerstack ever again if I did. Would be size&weight, I do like the rubber bottom. Less heat. And if they truly just last longer as far as how many recharges. But, I think PS needs to be offer in bigger Ah options still. 5Ah is still small when running larger devices or high drain constant use devices. VACs/Blower/Job Site Fan etc.
Yeah, I really like the rubber bottom but gonna stick with the 5 amp 20V and the 9 amp Flexvolts for now. The 6 amp Flexvolts use 18650 cells where the 9s use 21700 cells. Big difference in power as seen here - ruclips.net/video/jBiCKUnBC3w/видео.htmlfeature=shared&t=369
Can we all just admit that, our fathers tools were inferior to what we’ve been blessed with! Majority of buyers will never use these tools to their true potential in the end. For me, I have DEWALT tools, and a ton of money invested, so I will never switch. I don’t blame Milwaukee, ryobi, makita guys, etc. either.
Battery tech has really unlocked the power in cordless tools, my flex volt grinder has a peak output of 2,300 watts, the most you get out of a single plug on the wall is 1,500 watts continous, a 9 amp powerstack would reach 3,000 watt output easily.
Have you done a video comparing the 60v dewalt circular saw? I have had mine, running 9ah batteries,(very rarely using 6ah) for about 3 years? My makita lxt has become a dust collector.

i wish the battery manufacturers put a simple aluminium heat sink instead of plastic holders for each cells so that these dont die early and remain sealed from elements, with so many gigapresses and die casting available these could be easily made and anadoised, and shift to 2170 tabless like Makita 40v 5 ah once, cells and to me 5ah once are the only i could afford,
Unless these are for your dayjob I really don't see the price for the PS being justified. Still getting good battery life from the three 4AH 18V that were included in my combo kit in 2013.
batteries from 2020 they started to have problems i still use the 2018 2019 new models are really bad costumer service is good but i dont wantr to change batteries every 4 months 😔😔
I wouldn't worry about the 8 hr charge to fully charge each individual cell. There's probably not much difference between that and a regular full charge that takes an hour or whatever. But yeah, apparently there's fully charged and fully-fully charged.
I don't understand the difference with the power and runtime thing with the power stack vs the xr. The ps is 20v 5ah. The xr is 20v 5ah. They are the same I thought other then the power stack able to live longer and being lighter and more compact
Pretty simple honestly..the 5ah powerstack and the 5ah XR have the same/similar runtimes however the powerstack 5 will give the power/punch of an 8-9ah battery, while the 1.7 will punch like the 5ah's without the added weight of them. This is especially helpful in tools with variable power outputs, like impacts, drills and such. They were made primarily for mechanics who need the extra impact punch without having to have the weight of the brick sized flexvolts hanging off them.
