------------------------------------------------------
This Test Revealed Some HUGE INFO! First, does a 5 Ah battery power tools for the same time as a different style of 5 Ah battery? The video clearly shows if 5Ah batteries last the same amount. What came out of the testing was crazy. PLEASE NOTE: I ran this test twice to be sure the numbers were correct. I ran it on the 2022 XR 5Ah battery and again on a 2019 XR 5Ah battery to be sure of the results. I did use footage from both runs as I had some recording issues. You might see two battery dates in the video. Technology strikes again and corrupted some video.
So what we found is that the voltage held in the PowerStack when it is dead is MUCH higher than the XR 5 Ah battery. When the XR 5 Ah battery finally turned off it was in the low 12's for voltage. When the PowerStack turned off it was in the low 16's. So the PowerStack will deliver a much higher voltage and amp output for the same runtime as the XR 5 Ah. The PowerStack will give you more power in your tools for the majority of the runtime. When some will start to feel a lag in a high output tool with an XR battery, the PowerStack will keep performing like a fully charged battery up until the last 10% of the runtime.
We have a lot more work on this to compare the output of the PowerStack battery. Since most people feel that the 5Ah PowerStack is very comparable to the XR 6.0, we will look at the voltage held by each battery and where the voltage lands as the batteries continue to deplete. If the XR 6 Ah battery performs like the XR 5 Ah battery, then the price DEWALT wants for this battery would make it worth the upgrade!
We have a lot of work to do to prove this, but we are on the right path. Stay Tuned! - แนวปฏิบัติและการใช้ชีวิต
Both containers hold might 5 gallons of water, the XR is just a bit sloppy when it's pouring that 5gal out.
The higher voltage cutout of the PS would also seem to indicate it does have more total capacity theoretically but the pack is using a BMS that cuts it off short, probably to protect these pouch cells for heating up and expanding. With more voltage on the table before the BMS calls it "dead" it's going to deliver more power throughout a charge. Like a 6-7Ah battery they label and cap at to 5ah of discharge.
"Both containers hold might 5 gallons of water" It seems like you are saying they don't actually hold the same amount, but are designed to have the same amount accessible for use. The PS one being like a 6-7 gallon container that only allows 5 to be poured out.
This is most likely what's going on. Samsung and Apple do a similar thing with phone batteries, where '100%' charge is closer to 80% to reduce stress on the cells and hopefully make the batteries last a few years.
Good way of putting it
Running the drill without drilling or screwing is not quite a good test I feel . Drill holes till it dies or screws in how many etc.
This is sorta what I have observed using a 1.7 AH powerstack on a 3/8 impact everyday. Its feels like maximum strength until the battery dies rather suddenly. With the older batteries there was a little bit more warning when the battery was low.
Which is funny because back when these companies started pushing Lithium over Ni-Cad/Ni-Mh, they told us that the Lithiums run full power through the entire charge - unlike the old batteries. Granted, they were a big improvement but obviously the claims were...embellished.
The power stack runs big tools way better. Can barely run a saw with a normal dewalt battery while the power stacks rip through the thick wood with no problems. Power stack are better period. Lighter stronger and charge faster. Now plug them I to a chop saw and see which one is better. I know already because I've done it.
@@matthewotis3594 Just a question on the weight, some reviewers are saying the 5ah PowerStack is 1.5 times heavier than the XR 5ah battery.
Brillant Review, straightforward and easy to understand...
What he said 😂
This was so helpful for me. Thx!
Just the fact the Powerstack stays cooler and gives the tool more power has me sold. Powstack is a beast!
it feels like they were made to run the guns so you dont get that low power fire i just ordered 2
Excellent work
Thank you
Great vid. Big fan of your content keep it up
Appreciate it!
Pretty good test, on the other test you had the voltage meter hooked up during the test which would give a more accurate final voltage reading. Even better would be a DVM that can store the voltage over time. I like that you took the final temperature. Though you said that you charged one of the batteries directly after the test while it was hot for an additional “test” of battery pack over temperature heating, maybe it could have been suggested that this was a test and it is generally preferable to allow the battery to cool down, but then again, this is how some people do it (could hurt the life of battery).
Pumping out content thank you great video idea!
More to come!
It's important to remember that battery capacity tends to be determined by low current discharge tests. This will usually give you the largest number. High current discharge tests like this will usually result in a lower apparent capacity as more energy is lost to internal resistance in the cells. The powerstack is clearly losing far less energy to internal heating. The powerstack also seems to have a much higher voltage cut off than the old 5ah (3.3v vs 2.5v) which will affect apparent capacity.
Nice video and yes, I would like to see the same batteries or even a higher amp on a drill or any other tool
Good comparison 👍
Excellent review 💯
As the blower, with the XR battery, is going lower it would be interesting to know what temperature the heat gun is putting out. If it’s not putting out the same heat after 8 mins you may find yourself heating up the surface longer to get the same results you were getting before 8 mins.
I know this test is the most “fair” you can get for consistency reasons but from the results I’m seeing, if this battery was attached to a motor using high strain such as using a hole saw to cut as many holes as you can in a 2x12. In that case, I believe, the stack would outlast the XR which kinda translates to more run time, with technicalities. Like I said before, it’s less “scientific” because you can’t guarantee the same consistency throughout the lumber.
Very interesting tëst. It tells me the power stak had an overall higher output in watt-hours becos of the higher ending voltage. So, they both may be 5 Ah, but certainly not the same Wh.
Phenomenal content man as always. Definitely appreciate the time and effort that you put in to it.
I appreciate that!
@@WorkshopAddict what he said.😂
Dude excellent job! I've wanted to make a video like this so bad showing the difference with the PowerStack batteries. I think the ultimate DeWalt battery is going to be a 9AH 60V FlexVolt Power Stack! I think 60V Flex Volt Power Stacks, will be the real game changers. I'm ashamed that I don't have any of the new 5Ah Power Stacks yet, hopefully there are a couple under the tree this year. You've been rockin out the cool videos bro keep it up.
to get that 60V, you have to kinda triple up the configuration. Not sure were that gets us with the current PowerStack config: did DeWalt triple the 1.7Ah to get to 5(.1)Ah, or is it a new design? For 60V PowerStack, they might start with a 1.7Ah *2 *triple = 10.2Ah ??
@@wim0104 lol DeWALT engineers will figure that out for us
@@wim0104 Im pretty sure they got it figured out. They have smart people working on it.
Will you compare the 1.7Ah with the 5Ah packs? Curious how the weight and size changes feel. Is the capacity gain in the 5Ah resulting in a linear performance improvement? Or is the power a little worse? Same with weight/dimensions. The ergonomics of the 1.7Ah were a really attractive point, but it looks like it’s gotten quite a bit larger now.
Excellent test👍 Makes the Powerstack battery stand out for high power need applications maintaining better usability over the 5ahs of use. I often need to pull my 4ah batteries off of my impacts prematurely before their fully depleted when doing a lot of large lag installs on my jobs because the power output drops off just enough to make it more efficient to grab a fresh battery. I can see where the Powerstack batteries might solve that problem with the new battery technology. However it will probably be a while before I'll be switching over to powerstack batteries completely with the current price of that 5ah lol.
I get it, the price is steep. BUT, we are starting to see why some might be willing to pay for it. If you think about it, we use our batteries at close to a 50% charge much more than we do a 100% charge. So the tools we are using might not perform like we think at a 50% charge, until the PowerStack.
@WorkshopAddict That's a very good point especially in constant high power applications.
curious to see a graph showing the current draw for the timed trial.
Can you please do a Powerstack 5aH VS THE 6Ah one? Thanks.
Most of the die grinders with speed control are cordless but I want the corded type!
I was surprised that the classic batter discharged below 13v because I knew makita batteries don't discharge below 14v. Interesing video
Great video
Yea the power stack is the man!!!👍 why I bought two 6 Amp hour batteries for 199.00.
One parameter you didn't measure was the heat coming out of the heat gun. Did that drop as the voltage did?
So my wife is having me redo our siding and I’m picking up the dewalt cordless roofing nailer. Started looking into getting one of these in a double pack. Since I’m saving a lot with doing the siding myself I guess my question would be which one for a nailer should I get?
Would be interesting to watch the output temp of the heat gun during the test. What I see with the xr is after about 5 min. with an xr, it just isn't throwing heat like I need it to.
good video, although I think you made a mistake with saying the 5Ah has 21700 cells, they use 18650 cells.
regular cells quickly drop this output or performance if you introduccing screws , at 8 minutes your speed noticeable down ..
I said that because most common work is with the drill or grinder may be with 5 ah battery it s half day run time.. not 16 min..
Here's a question do the dewalt battery packs gave a 20% cutoff to prevent flattening the battery's as I've read that if you run your drill driver etc until they stop working that's a bad thing fir your battery and I've read that they meant yo last 3 yrs
The bars on battery checker are handy but I think I'd prefer some a bit more accurate and if there's no automatic 20 % left cutoff then I'd say why not as that would protect your battery in long run better to do a full recharge then
I was wondering how the pouch cell tech will hold up overtime with repeated charging..
But just checked how many time you can expect it to work.. according to a google
The standard 2ah charges 500 x's
The powerstack charges 1000 x's and performs a little better than the same ah rated battery with power ceylinder type cells the reduced cost if 2 being in a combo kit.. is a bonus cause powerstacks cost more than the originals that have the cylinder cells..
So I feel safe enough going with the new tech powerstack in the combo kit deal to avoid the added expence..
And time will only tell just how many charges they will hold and how well they will perform after however many charges... unless anyone else cares to contribute their long term experiences... I would apreciate that...
Project farm ran a test of these powerstack batteries as well...
It was also informative...
And
Big Thanks to all you guys who put this info and findings and independent tests up here on youtube..
It helps me to make good decisions about the tools I use as a handyman..
excellent
I kind of wish tool battery’s where rated like hobby grade RC batteries with a discharge rating or C rating. That would cut through a lot of the confusion with this new battery technology.
I'm curious if these new pouch cells are actually lithium polymer kind of like airsoft and rc batteries
Which is the better battery?
Power stack or XR battery?
Because I am about to buy one very soon hopefully by next week.
Please advise me?
That’s what the powerstack package says. Right on dewalt!
Heaven help SBD/Dewalt trying to explain the benefits of this technology to the average folks to use these tools out there lol...I can't imagine it makes much sense to someone why their battery is 2x as expensive now lol....The Stack batteries are superior in every single way. AMPERAGE OUT is the main benefit. You get all that power, all the time until it's dead. The tool doesn't have to constantly step down in performance like they do with Normal Cell batteries. Great video as always Brian. The advantages are more than clear from this method. Still somewhere, someone will say "But the old style lasted 30s longer! lol..
Great video. Unfortunately, I have had nothing but problems with my powerStack batteries. Run my drills, flashlights, saws for about 30 seconds and then nothing. Like the batteries are dead. Got a 2 pack of 5a PowerStack batteries and both are faulty. All my 5a XR batteries are still going strong. Really wanted to like these new batteries. Anyone else having issues?
Powerstaks are freaking awesome!
Sounds like the powerstack has a higher delivery rate but in my opinion for low power draw applications like tek screws or drywall screws, it is not worth spending any extra money. If you have a tool that is already heavy enough like a impact driver and you might only use it to change a tire, the powerstack would be nice because you don't need a lot of stored amp hours and you can get the job done with a lighter 1.7 amp hour battery because it can deliver the same initial amperage/voltage= wattage as the heavier 5 amp hour Max
Greetings. How did DeWALT batteries perform after a long time?
Even after 7 months since this video release the 5ah PSs are still too expensive. Have to stick with my 5ah XR batteries till the price is more affordable.
and they're still way expensive 9 months after you post that comment
I just purchased my first powerstack 5ah battery. Looking to get a second one soon.
@Stevo8800 let us know if you're happy about the power vs price!
How is the weight?
عندما تعمل مع البطاريات فليس هناك قانون ثابت ايهما افضل من حالة تشغيل الى اخرى يختلف اداء البطاريات
I wonder if this is why they claim the ps can take so many more charge/discharge cycles. Each cell has almost 1 more volt when it shuts off which is way better for the cells
I just got a set of 5AH powerstack batteries for 250, at Lowes, and they gave me a free dewalt 20v router. 😮
199 now with free tool
depends on the tool, and an old XR 5Ah will obviously have a capacity loss: ppl out there are comparing their old XR's to a new PowerStack, I bet. But good to know that the powerstack keeps the voltage high for longer, so for high output tools, it does put out more work.
My 2019 Xr was identical to this 2022 XR. I thought I would lose some capacity in 3 years, but the times were within seconds.
@@WorkshopAddict Great to read that!
@@WorkshopAddict yup, I have old XR 4Ah from 2015, and they still haven't run out of cycles!?
I'm wondering how the powerstack would do on the xr angle grinder? I know the xr 5ah does over heat very easy under load. I do use the 6ah and flexvolt batteries with no problem.
I’m going to test this getting a grinder and power stack tomorrow
@@darrenjowett8032 I got a 5ah powerstack last year and it works great on the angel grinder
Is it worth to close to double the price? I really don’t think so. If you have enough batteries and the proper charger, it makes sense to maintain the XR batteries.
Thanks a lot, but I would compare to a 6Ah battery with 21700 cells. While 5Ah still uses old 18650s which handle high output much worse.
I have only used the standard 5ah with the heatgun. 2ah was abysmal.
And the so called 5ah compact Powerstack is larger than the XR 5ah.
Nooice!
What about gun heat output temps, run time is one thing, heat time matters here 🤷♂️
I’m guessing the PowerStack batteries have a battery protection module whereas old Dewalt batteries didn’t. The PowerStack stopping at 16.35V is ~3.2V per cell, which is the safe low voltage cut off for lipo batteries. Going lower gets risky and can lead to permanent battery damage and rapid degradation.
I thought I heard one of the reputable tool reviewers say that the powerstack batteries aren't actually lithium polymer? And I'm wondering/guessing that you might be able to run an 18650 battery to lower voltages safely then the new tech powerstack whatever bat chemistry it is.
@@duncdunc76 I had also heard that Dewalt stated that they were not lipo cells, which is good because lipos require special care and can be dangerous if mistreated. I was just noting that it seems like they may now have a battery protection module to prevent over discharge and they stop around the same voltage as lipos.
they BOTH have protection, but flat cell batteries are prone to catching fire and/or exploding at high temperatures (remember the galaxy note 7 debacle?). the flat cells have to be shut off at a far lower temperature than any round cell battery pack. if you want consistent output batteries that are work horses, buy the 4ah or 6ah XR batteries with the 21700 cells. the "powerstacks" are a colossal waste of money. for the price of one 5ah powerstack battery you can get THREE 4ah xr battery packs, which are still light and compact without sacrificing performance or capacity
@@solomonshvI got my 5ah power stack for 80 bucks lol
@ihadalife1177 Nice where did you get it?
Won’t the power stack out last the X-ray not getting as hot
So, this sounds a lot like the difference between teslas and the new Porsche taycan. The Porsche tag can is advertised to have the same constant power now matter what the charge is. Teslas lose power as the charge drops. Nice test
So what’s better ??
Wanna see stack pack on cir saw riping
I am working on getting it all together.
@@WorkshopAddict beast!
Can powerstack 20v 5Ah provides the more power than XR 20v 5Ah for DCD805? I'm still confuse, which one should I buy for my DCD805...
What are you looking for? We have a Dewalt video out on how much the voltage drops on each battery. The main rule is if you are working over your head or not. If weight is an issue, the 1.7Ah PS provides great power, but it costs a lot of money. If you just want a good small battery pack, the 4Ah compact battery does just about as good as the PS and is less money. The 5Ah is also easy to find on sale and does great, but it is larger. It is more about your needs than the power of the pack for an impact driver.
Bottom line does the Powerstack last longer before it goes dead? And if it does is it enough to justify the cost!
Powerstack uses Lithium ribbons - you cannot repair it. XR uses individual cells - you can buy replacements and rebuild it.
If the discharged volts were higher on the power stack do u think it may regarg quicker ? I’d be interested in the charge times from completely dead to fully charged
I think that might have damaged that XR pack, that finishing voltage was too low. Being interesting to see if it keeps performing longterm after that.
Good vid.
Yeah thats why its a good idea to change the battery out when you notice a substantial drop in performance of the tool.
So I did nothing out of the normal. If that damaged the pack, then there would be a HUGE issue with Dewalt 5Ah batteries because the BMS in the pack did not turn it off. AFAIK, Dewalt 5Ah packs are rock solid and super reliable. I charged this pack right away and it did not even thermally time out on the charger. I get what your saying, the voltage was super low. But how many people do that daily?
i have noticed in the past afew of my packs ran down to 12v, tested straight after use, now that is only 2.4v per cell, and that is off load volts, it could have been lower when on load. . . so i always thought that the bms in my DeWalt packs only served to do balance of the cells, but no top end or bottom end shutoff of the cells or pack. .
Gotta agree with WorkshopAddict on this one. If Dewalt isn't building in a safety cutoff for its batteries for case uses just like this then they wouldn't be the Big player they are in the power tool space. I'm sure every reputable powertool company puts safety cutoffs in their batteries exactly for the reason that professional users will be pushing their tools hard in the field.
@Workshop Addicted definitely wasn't accusing you of doing anything wrong, just surprised to see such low voltage.
I've been lead to believe that Dewalt only put the battery protection on the tool, that right? Don't think there's enough room in a battery to fit the gubbins needed.
Like I said, Great vid. 👍
So by multiplying time by voltage, you can say that the powerstack has more energy to give to the tool, so in real life usage, the runtime is not relevant.
That means that if you need to crosscut 100 2*4, the powerstack will do it faster, where the 5ah will not finish the task due to low voltage.
Bingo 👍
I think for high power demand tool tasks your probably right. My thought however is how many tasks require that level of power demand where the old battery tech can't sufficiently take care of the job and at a much lower cost currently compared to the price of the powerstack. I mean if you can buy 2 old tech 5ah bats for the price of 1 powerstack then assuming you've got charging capability on the job site your getting more work done for your money with old tech bats. Awesome new tech for sure, it just isn't going to be on my job sites for a while with the current price of powerstack lol.
but one is cylinder one is stacked one does cost more than the other.
Just spit-balling but what if you test each battery at its rating? What I mean is test the 5Ah batteries under a 5 amp load to see if they last an hour. Test a 6Ah under 6 amps, a 4Ah under 4 amps, etc. See if they actually run as advertised (since that's all the Ah ratings actually mean).
How many people use tools in the real world that way? My goal is to do enough tests that people can choose if they want to drop the money on this battery for real world stuff.
@@WorkshopAddict I'm simply talking about finding a baseline for the claims made on the batteries. Not just the PS but all of them. Nobody said that's how people use them. Perhaps people would like to see if the Ah ratings are true or if - like many other things in the industry - they're embellished, as well.
😎🛠️😎🛠️😎
Guys li ion and li po are diffrent. Li ion =long run, li po=fast run. Li po will out perform li ion only under extreme loads. Not so much to do with bms settings. Standard lipo cut off is at 3.0-3.2v but li ion is 2-2.5v but both max out at 4.2v😊
Maybe the lasting much longer is not a per charge comment. Maybe it is the life of the battery. The XR can be charged 400 times. The power stack is supposed to be rated 1200 times charged.
Need battle 10ah XR vs 9ah flex. Run time and voltage
I will have a few batteries in the next video with much more info as to what is happening and when. This was an eye opener.
@@WorkshopAddict Very interesting content you make. I look forward to new one's.
buy 2 er's for the same price and get working all day!
I like the 1.7ah power stack batteries but I do not like the 5ah power stack it is too big and clumsy looking I would rather use the standard xr5ah battery it is more compact than the 5ah power stack why couldn’t DeWalt make the larger ah power stack batteries more compact ? Maybe later down the road hopefully
Yeah I agree now that I have one of the new 5 ah Powerstack batteries. They are huge, similar in size to the 6 ah XR.
Wh is the correct unit. To test them properly do it on a battery tester and plot voltage and current and power over time. Your test didn't prove anything much really. As for voltage vs capacity, lithium ion does NOT hold doable voltage to empty. Quite the opposite. It linearly degrades from full to empty, hence the dumb led capacity meters on the tools work fine. This is chemistry based, so both should be identical. The lower cut off could be real or could be a faster spring back, again, flawed methodology. If you'd like some help designing good tests to avoid comments like this, reach out, happy to help.
that 5amp xr battery will not make it to 5amp I have tested them and the are closer to 4amp hr the powerstack are what they say they are 5amp
Так а зачем фен использовпть? Они одинакого отдают 5 ампер в час. Только вот с powerstack ушм 409 будет не 1000 ватт, а 1400. А это влияет на обороты и скорость. Тот же шурик будет крутить мощнее. Пилы дисковые тоже . Фен самое необьяктивное.
OK, so your conclusion is that the original 5ah@20volts is not actually 5ah@20volts? Energy is Energy and if one battery has more power than the other, than Dewalt needs to come clean.
5ah is 5ah, but the PowerStack can provide power to tools more efficiently, creating less internal heat.
Also just to add, any heat generated is a net loss of energy through conversion. So both may start out at 5ah , but one has less ability to transfer all 5ah to the tool.
@@jeremymyers5643 OK, so the 5ah@
20volts in the older configuration is the potential energy stored in the battery... but apparently it can't deliver all that energy... I rest my case. People purchased a battery based on the assumption that it has a deliverable energy of 5ah@20volts.
That will vary depending on the tool it's on. High draw tools obviously heat up the battery more. Put it on a blower and you'll have less capacity then when it's on a small flashlight because the battery doesn't heat up when using the flashlight.
@@trekmcdonald9608 So when a customer asks "is the 5ah powerstack worth it over the regular 5ah" the answer is "it depends"? Currently, my understanding is that the 5ah powerstack has the ability to deliver more energy at once than the older configuration , so that is what I will be telling buyers... hope I am correct.
The powerstack will discharge its power cause it has less voltage drop
Hmmm weird honestly i heart the by the 18650 on 16 really take slower an litterly stopped at 17 minutes an a few seconds it was for real to notice the pouch cell litter stopped early than the 18650 dewalt bettery pack of the 8 amp an i worked with pouch cells but they are really weaker than the 18650 cell if you had noticed a bit and pouch cells wont last long honestly than the 18650 cell bettery an wont have much good effect in cold so in my opinion pouch cells are weaker an wont last long than the traditional 18650 an the 18650 cells are much safer an last longer i ain't lie bc i have an first Hitachi impact driver you know generation 1 with lithuim made in 2009 or 2007 but it still works very much good the job an pouch cells after 6 years its dead flat completely an it going get swollen either till it can explode pouch cells Arent safe at all
Twice the price of an overpriced battery for a better power drop?
To me it's not worth the price!
In my country dewalt xr 5ah costs 70 euros and the flexvolt 5ah costs 110 euros does it worth to go in powerstack? I want to use them on my dewalt sds
I dont want to go in flexvolt mostly cause of the weight
I will have more videos coming to help answer that. right now, the XR 6Ah is a great cost to power ratio.
@@WorkshopAddict unfortunately not available in my country we have in 18V from 1.5ah up to 5ah and then it goes 9ah flexvolt up to 9 ah the rest are different volts :( As for the worth to buy thing I saw also some other videos but your example about the 2 buckets of water the xr pour it almost immediately the powerstack has a steady flow as a result same power till the very end of the battery and more time . And what else we do care a lot weight and space powerstack seems smaller and lighter. Also forgot to mention in my opinion it don't worth to buy in something small as an example I won't use them on my impact driver I already got it with 2 5 ah I was afraid if it was an overkill well for me it was I mostly screw and unscrew drills and sometimes I screw 10mm drills in walls that's when I use it hard or 13 mm unscrew drills I haven't charge it for months the indicator is still full so I am thinking to buy a new 2ah battery just to lose some weight on the sds from the other hand especially if u dig yes you need power and time or for the grinder and gosh the grinder empty the 5ah in 20 30 min I think powerstack might shine in these two tools
Check out this Dewalt video:
"How much more drilling power does the DEWALT 5Ah Powerstack battery have in our runtime test?"
They compare the 5Ah PowerStack and the standard 5Ah battery while using the DCD805 drill and are basically saying that because the PowerStack delivers more power it will get more done in the same amount of time. Which obviously makes sense, and i think this is why some people are getting the impression that it lasts longer when you've just proven it doesn't. It would be cool if you replicated the same setup. Great vid btw!
