I feel like the tool company's gain just as much from you guys now as we all do. And I really appreciate honest, unbiased testing.

I love this channel…the people’s channel

A while back I commented on the fact that Stanley B&D and others were really not into the tool selling business but rather, they were in the battery selling business. This video proves my point.

Great job fellas You guys are putting in the work. I hope your channel continues to grow a bunch.

My two best youtube channels! You guys are the consumer report of the KZfaq world. Torque Test Channel and Project Farm🙌❤. Keep up the good work.

I’ve sworn by the 6AH XR for close to five years now. I have an assortment of different DeWalt batteries, just got a two pack of the 1.7AH Powerstacks this week, but time and time again I find my tools hooked up to the 6AH XR. The length of time the battery lasts under use paired with a modest weight really keeps me coming back.

Was really looking forward to this one :) thanks TTC!

Just the info I was looking for. Thanks!

Oh, man, I was about to request this exact video. Glad you guys were a step ahead of me.

Got to love DeWalt for pushing the boundaries on both tool performance and batteries. You got to know that this makes other companies take notice and will have to step up their game if they want to remain competitive. In the end, the consumer benefits by having better performing tools to pick from. Keep up the GREAT WORK, I believe your videos make a difference forcing the tool companies take notice of where their offering stack up in your tests....

Thank you I've been waiting for this one!!

My biggest take-away from this video is that my next battery purchase should be a 9Ah FlexVolt. I currently only have one 9Ah FlexVolt to run my 60V tool, and sometimes it runs out of juice before I finish a job. I was debating getting a 6Ah as a backup to the 9Ah, but it looks like it's a far better call to get a second 9Ah. As for the 5Ah PowerStack, I simply see no compelling reason to buy it based on this video.

I like how the 6AH 20v performs. I would love to see some testing with the 8AH and 10AH 20v as well. I have used all three of these on impacts and it seems like the 8AH and 10AH can out perform the 6AH. Great videos! Thanks again!

Wow,The most informative video in the history of this channel!...This one will be king of views in no time,fantastic job TTC!

Another great test! My favorite battery packs are based on 21700 cells, since they are better than 18650 cells in every way. And the cells often are replaceable, making the battery easy to repair. Pouch cells tend to be much harder to replace. For future test the inclusion of model number for the cells that each brand uses for different batteries would be nice

Just like you I assumed they would be smaller. Lipo are awesome but have one huge drawback; they hate being stored at full charge (4.0-4.2V per cell). They however will have 10x lifespan if stored at 3/4 charge/3.8V per cell. A lot of high end electronics will self discharge a battery pack after 24-48 hours to this voltage to preserve the pack overall life. Curious what the initial pack voltage is? And if it self discharges?

Excellent content. For me if you want small grab the 1.7 and large just grab the XR 6.0 as for now there is no way the price justifies the 5.0 stack battery and the size that it is.

Alright, post viewing takeaways... When I chose the 5PS, I was deciding between it and the 6XR and these results show that I was making the right comparison. That's good news. Because of the reasonable size, I can (and have) replace all of my smaller batteries for my smaller tools with them. But because of the performance, I can feel confident running it in my bigger tools as well although, I am going to keep my 8XR and 10XRs handy for their extended run time over this one. NICE! This is the comparison I was looking for, for a week and taking the leap without seeing it. Like I said, most people saw the number '5" and wanted to compare it to the 5XR and it just kept winning because that is not the right battery for comparison purposes. Now, that ad you showed on Amazon for the 6XR for 91 bones...that guy is still running that ad here in the future. He's at $84 now. And for that price, I was tempted to go with the 6 and just buy four from him. BUT...I am a little gun shy. I got burned recently on ebay, and ended up with two counterfeit 5XRs. So I dug deeper there. Amazon is an authorized DeWalt seller, but everyone who sells on Amazon is not Amazon. That guy is not Amazon. So I jumped in the questions section and asked the direct question. He answered that he is not a DeWalt authorized dealer. Understand, that does NOT mean he is selling fake batteries. His batteries may be right as rain. It just means you do not have the guarantee. Whether you should take the chance or not is up to you, but you should absolutely have this information going in. You can buy a 2 pack of 5XRs directly from Amazon, without that risk. Those go for 196 so...about $14 more per battery. On the flip side, I paid 300 per two pack at Lowes for the 5 PS. Yes, I could have found a better price, but Lowes has a program where they let you pay for your stuff over 90 days (as them about Progressive Leasing), and it doesn't cost much (unless you go over 90 days...on day 91 they ream you, so be careful there). 200 per month for 3 months (I bought two 2 packs) was just easier for me to handle right now, so I did it that way. There...now we all have the benefit of each other's experience, and everyone else has all of the information they could possibly need to make good decisions.

Wow! This new 5Ah Powerstack really kills it here! _looks at price_ ...But what's another 1/2 pound on top of an 8 pound tool, anyways?

The PowerStack 5.0ah is bigger than expected. I ordered one from Hm. Dep. & returned it, as the slight increase in power was 'outweighed' by its & cost...

Not to many other channels put in the work that this channel does!!!!!!

I don't even have dewalt battery tools but I still turned this video on in order to watch something about this ps batteries. There are getting more and more different batteries on the market:) thanks for showing killograms, pounds and drives me crazy

Great video as always! When I can get my hands on the new powerstack I would like to see how it is for power and run time the brushless angle grinder.

Great tests. You can get the 15.0 right now for $250 so $235 for the 5.0 PS is ridiculous.

These PowerStack batteries are awesome. I absolutely love them because they do give a LOT more power than the standard XR batteries. I had an 8ah battery on my 7-1/4" miter saw and swapped it for the 5ah PowerStack and my god! It chews through boards like butter. With the 8ah, it liked to bog down and then kick really bad, so I had to run the saw really slowly so it didn't kick or bog down. I thought it was just underpowered and turns out that it was. That 5ah PowerStack is a beast!

You should test Ryobi's 18 volt cutoff tool as a part two of this test. Also, I would like to add that some tools may have constant velocity compensation that can make the RPM stay constant within the load range rating of the tool. What constant velocity compensation (also known as IR compensation) does is try to keep the motor running at the same RPM under various load conditions. So say for example you have a DC motor that needed to turn at 500 RPM and you needed 12 volts to do that, but it keeps slowing down as you apply more load. Well the way around that is using a controller with velocity feedback by either a sensor or indirect measure of the armature voltage and higher voltage applied to the controller. The controller will increase the voltage as soon as the RPM drops keeping the RPM at a dead steady 500 within limits of course until either current limit is reached or run out of voltage or over heat protection kicks in.

Great information!

I noticed an increase in power on my 1/2" impact a few years ago when I bought the 6ah battery. It was a nice bonus

Wow that's interesting, I got one yesterday for around US$140. Nice to see we got a better deal here for a change.

Great video. I’m not a Dewalt guy but interesting technology that I can see all the brands using. Thanks.

"It handles like a trailer with a blown tire"--best line ever on TT Channel!

Great stuff as usual! Makes me wonder if this Powerstack could make the 20v Flexvolt advantage circular saw perform on the same level as the 60v saw.

DeWalt is really stepping it up. Nice testing!

Good work guys. Will have to pick one up once the price goes down.

I have four 8ah bats.Wish I knew you needed one for this test.

That is really interesting that you can see that battery's power curve in the torque curve.

I've fallen in love with this channel. It shuts sooooo many dudes in the shop right up

Wow impressive that the 5ah PowerStack was a few foot pounds lower then the 15ah that I wasn't expecting @Torque Test Channel

Fantastic work.

Wow! I don't know how you do it, but you guys keep bringing awesome content to this channel. Thank you! Where's your tip jar like PF has?

This is completely irrelevant to the video but. My boss just bought the mikwaukee 1 inch D handle extended version! He bought it to take off the tires of our big rig international. I got to use it to take one of the tires off. That thing is awesome!

I stopped watching my morning motivational video for this as soon as I got the notification. Worth it. 😆

Very impressive video. Subscribed

The nice thing about 18650 and other cylindrical cell batteries is that they can be rebuilt and repaired with commodity cells. I'm guessing that won't be the case with the pouches

just about to start investing in some dewalt stuff, i feel the 6ah XR and the 9ah flex volt are the two stand outs, also the 1.7 power surge for small stuff, everything else seems to be a bit to in-between or limited.

I really like the PS batteries, especially the relatively tiny 1.7, but the size of the 5 is very helpful when I set down some tools in the upright (standing) position.

Thanks for the info 🇯🇲👍

Thanks for your videos! Hyper Tough has a new brushless impact driver clone of the M12 that they sell at Walmart, can you test vs the Milwaukee.

Interesting and love the test and the visual charts a really good comparison but I won’t be running out and replacing my 5 and 9 ah batteries just yet

I knew as soon as the first one came out a year ago, there must be a bigger one coming. So like you said, this time next year, we'll probably get the big boy!

I love your videos and the data you output. What about using sand instead of water for volume measurements? A bit of shop air and its all cleaned up!

I love my 1.7 PS batteries but like you said the 6AH is the sweet spot. Can’t say I’m sold on the 5 PS just yet. Maybe if price wiggles and I can get them for around 125-150/ piece

So my 6 ah’s is still the way to go!!!! Thank you for the data

It would be interesting to see how much age of the battery affects the test results. Would you get the same results after the battery is a few years old?

9 FlexVolt is an absolute beast love using it on my 60v sawzall

Im choosing Metabo 18v grinder on 9Ah FlexVolt with adapter (or 9Ah Makita, same and cheapo, but no FV in future, with SONY VTC6 or LG HG2 both have their yay and nahs). This was a good time with Your channel I wish I could like twice. Heck, Ill find random vid on Your channel and like it just because I can and You deserve to be mainstream. It was great friendship for me, Ill flashback You with Respect. Much Many Thanx, Mister. Thats what Internets are made for.

Wow at how massive the 5ah PowerStack is vs the 1.7ah PowerStack interesting @Torque Test Channel

Bro you been putting out a video a day seems like 😂 it’s awesome. Have a great week. Thanks for all the info and entertainment!

I'd like to se similar test with the Flex tool line - they also have standard and stacked Lithium versions.

Have you considered a food vacuum sealer for your volume tests? It won't be perfect, but it might be better than you current methods. The food grade plastic is thicker than a grocery bag, but it doesn't bridge voids _too_ badly in my experience. Just a thought. Keep up the good work.

Could you answer or do a video to see if any user input can affect the power curve? Such as twisting your wrist or holding it really tight, pushing towards the bolt really hard etc?

do a run time test you ll be blown away I saw like double the screws on one battery compared to a regular new 5ah

I can’t even afford the normal batteries

Wow the UK version DCBP518-XJ which has been available for a while now is currently around £120-£130 inc VAT, think I might pick one up before they hike the price.

RIght now, it's 1/4 smaller and lighter, but 1.5-2x the price in singles. The DCBP520-2 ($349) vs the DCB206-2 ($269)....I'll stick with the 6ah packs for now I guess. That extra $80 (on 12/7/22) is noticeable.

I'm curious to see if the Milwaukee cutoff gun has more power than the new Milwaukee m12 belt sander! As you may know folks are making there own m12 belt sander with cheap harbor freight air belt sander parts and mounting said parts on the cutoff gun. P.s love the content. Keep up the great work!

You guys should test kobalt tools with the 8ah xr battery

I love this channel but I can't find out what's in the flexvolt 12ah. If the 9ah (my favorite battery) has Samsung 30t's what's in the 12ah??

Nice. Maybe I need to make an adaptor and run my 18v snapon ct9075 with one ?

Would love if you did this for the flex batteries and flex tools

I'm waiting for the flexvolt powerstack

How does the 8AH battery fit in on the voltage sag chart??

Been waiting for the power stack to come out, just waiting for it to come to my city

Man, I was really looking for something that was the epitome of consistency.

While I only own a few Dewalt tools I do like that there are options to batteries. the only major Dewalt tool I own is the Multi-tool (Oscillating-tool). Smaller batteries (2Ah) are better for cutting up on a ladder, but cutting on the ground a lagger battery is ok. If the new PS batteries get smaller with more beans then that might be an option worth paying for?

Yup I agree these batteries are a beast i heave 2 of these and 2 of the 1.7

Im not suprised by size. Flex stack lithium 6 and 10ah are pretty big. Also i feel like not a lot of ppl realize that the 5ah is basically 3 times the capacity of the OG power. 1.7 x 3= 5.1. Is it triple the size or only double or in between?

So what main brand battery system is bang for buck needing a recip or sawzall pistol shape saw for stump removal work. Garden tools useful to have available as well as stihl 36v

Is there a way to mod dcf899 with replacing parts and make it powerfull like dcf900?

I was hoping he would do a displacement test on the compact 3ah battery so that I could see a volumetric comparison of the old generation 18650 based batteries with the newer 21700 counterparts.

I'd really like to see overtime how these batteries age. More so whenever it's between a standard charger vs. 'super/ultra' charger. Because up to this point smartphones have been the barometer of gauging that sort of topic. & they've been the first & most refined, yet still are at the mercy of chemistry. Except power tools draw more power & on average even more extreme demands, thus- how would it effectively (let's see some tests.. /wink /knudge) over time taking those additional things into consideration. Overall though, it's awesome to see (ignoring the price). The weight reduction alone makes a huge difference when you don't feel like your wrist is sore as hell just from carrying a battery that may as well be a small dumbbell + vibrations during whatever project/job lol

Excited to see this but I can't understand why they didn't shift the bulk backwards.

Circa 10AH powerstack flexvolt battery next, coupled with a flexvolt 3/4" impact wrench? I have zero use for it but it would be so cool to see.

Can you do a test of different Socket Hex Keys? (The sockets you use for Socket Head Cap Screws)

Would LOVE to see this for Makita XGT batteries.

I LOVE your channel, buy jeesus, you guys are confoosing... Spend a good bit more time on helping me figure out wtf you're talking about..

Did they put a capacitor bank in the flat pack? That's a very interesting voltage curve. I want to see what's inside.

Looking for recommendations on which impact drill and hammer drill to go with… im a plumber so Don’t really need the crazy high torque ones…but want something powerful that can live up to the daily abuse

What about a video comparing older battery tech like nimh and nicd with lithium. And touching on how they were used. 👍

Shouldn’t fingers holding the tool during the dunk account for added displacement?

i wonder how many batteries are put together well enough to max the tool they're going onto or even if later newer battery construction could do better.

Im needing a new drill and driver should i go with the 18v or 20v

Can you guys test the most powerful cordless miter saws? Especially since Flex just dropped that new 12" miter saw and DeWalt (new Flexvolt), Milwaukee, Ryobi, Makita, Hercules, and Bosch all have a cordless 12" saw. I want to know which has the most power. I'm assuming DeWalt due to the 60v Flexvolt version, but I could be wrong.

I currently run different DeWalt batteries and would like to know if there's any hints or tells to know if my battery is 18650 or 21700?

I would really like to see the 8Ah XR battery. I backpack with their newish little adapter to get you USB-C PD, because that can charge literally anything I carry, and I have so many Dewalt batteries to choose from, depending on how long I am out. In testing to see which battery delivers the most watt hours per gram, I found that my 8Ah XR is literally just 1g heavier than my 6Ah XR (which is one of your favorite Dewalt batteries). Back when the Power Detect stuff launched, I remember reading that the 8Ah was supposed to be able to deliver a decent power uplift over the 6. But who knows if that's actually true. For me, it does mean that the 8Ah is by far the most watt hours per g out of my battery collection (1.7Ah Powerstack, 2Ah, 5Ah old style, 5Ah Powerstack, 6Ah XR, 6Ah Flexvolt, 8Ah XR, and 9Ah Flexvolt). The Flexies are on the opposite end of the watt hours per g scale, they must use heavier plastic in their cases or something.

Is there anyway to swap a 3/8 anvil into a 1/2 anvil in a Dewalt DCF921b? I was given the 921b as a gift but can’t return it even swap as it was part of a holiday bundle. Is there anywhere to buy dewalt anvils? All my sockets are 3/8 and I’d rather not run a reducer all the time.

I bought 2 of these batteries. They are great batteries.

How much power does the 9ah flexvolt put on forward? 960? 961?

What about the Flex power stack ?

Damn that was quick
