Interesting story. Basically I was 10-11 years old, my dad has never taken good care of batteries until I was old enough to understand that ya kinda need to bring the damn things in during the winter.

We barely took a board off and went through 1 battery. It may have been also due to the fact it was a black&decker but still It was surprising the damage that was done to those batteries over two years of being in the cold for like 3-5 months. After this he still did proceed to do this until I was 16 when I got more into the stuff and told him.

I wonder if having the out-the-gate beans being higher would equate to more working efficiency overall - most bolts are going to be off in less time, meaning less capacity used up with each bolt.
DeWalt seems to think so, saying it's 1.7ah capacity is actually more than a 2ah because you'll need to use it less. But heat guns, nail guns, lights, laser levels... all these tools runtime just = capacity. Can't get around that without diggin up Mr. Einstein.

The size is awesome, capacity is fine for me. Waiting for a 1ah battery for Makita 40vMax, pretty sure the performance of the impact wrenches will be near identical to the bigger batteries when fresh off the charger. They could do for example an 1.05 ah using 10pcs 14650 Panasonic cells, but instead they chose to introduce a superheavy 8ah battery - thats 18v-16ah equivalent - to compliment the already big ones to hey had. I mean, the 5ah is the 18v 10ah equivalent and lasts even longer for real world work. Dewalt has the right ideas here, small batteries for small tools.
Great test! My main concern with this battery is cooling, the cells seem tightly packed. That might be the reason for the 1.7 amp hr configuration. It does look good on the impact:)
Pouch cells need compression with high amperage discharge, or charge. the compression helps prevent bloating, its not guaranteed to stop bloating though.
THANK YOU! I always, ALWAYS wait until I have seen you guys drop a vid before I purchase ANYTHING!! Now that we have that out of thd way, THANK YOU for telling us it is a 1.7aH!!! I haven't found that info ANYWHERE!
I’m here 2 yrs later and I just purchased the 5 AH version of the power stack. Knowing the original power stack is only 1.7 AH and it’s being run against 4.0 AH / 5.0 AH and it’s holding its own. I can only imagine that the new 5.0 AH power stack will be on par with the 9.0 AH flexvolt batteries.
I think that little power stack battery is a perfect match for the little DCF921 1/2" power house. But if you have a high torque impact gun, why not spend the same money for a heavier battery that will balance the tool in your hand and run longer? Thanks for doing this testing! Glad to see DeWalt innovating.
Thank you for your (as always) great analysis and testing. I'm really sick of 90% of the tool based youtube channels reading off DeWalts marketing talking points and creaming their pants over this battery without doing any real testing or showing any skepticism. Its an interesting technology... but really expensive for the capacity. I think its overhyped.
@@squirts1 you use them yet? Just impulsively bought 4 of them on a killer deal. From the testing I've seen it'll probably be primarily for my impact driver and standard drill, probably not a skillsaw or jigsaw though
Thank you for another amazing video, just curious if you guys would consider testing the cross brand adapters that are out there? The ones that allow you to put a battery from one brand on the body of another? Thanks guys keep up the good work
So far all my cordless tools are de Walt but I don't like the xr planner so I have just bought a adapter to try and use Makita brushless planner and hopefully run it with my de Walt battery's so I'd be interested in a cross brand video as well
@@briangordon1767 ua-cam.com/video/WgJI8Ikrd6Y/v-deo.htmlsi=P8BXwmyOa8YQePm7 It arrived! Definitely some useful information, I feel like its more of an overview, but there are a lot of brands out there to try and crossover with
I have plenty of batteries but I want one of these for my 887 impact driver for general purpose work. I just don't want to pay for it haha. I have the 60v circular saw and let me tell you that is the way to go for a circular saw. It's the one that convinced me to start keeping my corded saw stored in my garage and trust battery operated in my truck completely. I did also get the Flex volt hammer drill kit so I also have a spare 60v battery so it's fine having a backup. Good blades are a must with battery saws though, while I can use my old corded DW364 with several teeth missing from the blade, it doesn't care it just plows right on through, so I do sometimes miss that kind of power though.
This is why when we fly drones in the cold winter months we pocket our lipo's in our coat jackets to keep it warm so it doesn't preform like crap when it's cold. The higher the C rating on a lipo the higher the discharge rate will be. meaning more power.
The higher the C rating means it can handle more amps being pulled from the battery without damaging the battery. Amps is pulled, voltage is pushed. Not being sarcastic or mean, or anything like that. I'm a big RC nerd. Custom built racing vehicles. Also fly some aircraft and drones. Love my replica tanks that shoot airsoft too. Lol
Seems like a perfect fit for Atomic tools for everyday type uses, then switch over to a 5.0 or similar if you have the rate project that's actually going to need the runtime. And now you can go from tiny flexstack all the way to the 15Ah Flexvolt monster in the same tool family. If only SBD didn't charge such crazy prices for ALL of their batteries (highest $/Wh of any of the major brands IIRC) I might be tempted to switch over.
they have really good sales on their stuff if you can find them, i got a dcf921 with a 5ah battery for free through home depot. then i bought the powerstack starter kit and got a free atomic multitool with it.
Hello again Torque Test channel Thank you for another Great Video. Thank you for the research the capabilities of the Power Stack battery. I am looking forward to seeing more. Again thank you and Merry Christmas to you and your family.
For high torque applications 6S x LiFePO4 would make more sense - similar voltage, much higher discharge rate, possible high charge up to ~80% (e.g. 15-18mins for 80%). It will have lower capacity but lasts way longer, degrades much slower... and no cobalt needed. They will be partly supported by existing charges but not fully...
I agree. Definitely not going to spend money on these for the little benefit. Waiting to see higher Ah to see the real comparisons. Thank you for showing us the numbers
Probably best reserved for tools with a shorter operation time and moderate current draws. The close packing of the cells will punish the inner cells with heat buildup leading to uneven individual cell performance across the entire pack
British release in March is with the 2.0 power stack 👌 what the dcf850 was originally built around.... for me it can't come soon enough I have it on pre order with the 2 2ah batteries and the new ps charger for £299
Happy to see you started with cold testing before hot testing. ☀🌡❄ Batteries, for the most part, do not like extreme temperature changes. I live in Arizona, and the majority of vehicle batteries I replace are when the temperature dips down. Granted, vehicle batteries are not the same as power tool batteries, but your testing proves the same point. Batteries on their way out could start a vehicle in the heat of summer, but would fail to start in colder conditions. Working performance will be affected by temperature. Thanks for your time (and money) spent on getting real results!
I want to see the power stack versus the small DeWalt batteries (2ah or 3ah). That is this battery's true competition. Similar size and runtime. Bump up to the 4ah or 5ah if runtime is important.
Great test on the power stack. Thanks for sharing. I think this may end up being the future of packs instead of the 21700's? Will have to do better with run time though...
Very interesting... I was wondering when power tools would implement a pouch battery. But, like you said, I want more capacity. The slim pack is great for a small light tool though. At least it dosen't sacrifice performance to get you that... But you pay for it.
I saw the 2-pack of 1.7’s on Woot today for I think $116. Glad I watched this video before pulling the trigger on getting these. I’m looking for runtime for my DeWalt weed trimmer and leaf blower, not so much looking for more power for my drill / impact. I think that price is way down from a year ago, which suggests that maybe people have begun to see through the hype of these batteries. I’m hoping to take advantage of early-adopters and Greater Fools who bought the Powerstacks and are selling off their relatively new-ish 5 Ah XR batteries cheaply.
I remember when I first started watching your channel. I saw you holding up some kind of cordless impact up and it made the pneumatic impact sound and I rewinded it like 10 time trying to understand how the hell that cordless impact made that sound🤣🤣🤣
Recommend Welzh Werkzeug Air Impact Wrench Gun 1/2 Drive Mini Beast 1350NM 1.2KG Stubby upgraded my snap on mg725 and it blows it out of the water on Amazon for £150 and couldn’t be more impressed
The lifetime of these packs is going to be interesting to see. Those flat packs crammed in there like that could generate quite a bit of heat and reduce the life of the cells over time. Especially with a low ah pack that needs to be charged/discharged more often.
My m12 6.0s and boss's lxt 5.0s generally last all day in our impacts/drills. The added weight of a standard pack is a better trade off over having to have 3 batteries for the day with the added cost too.
If possible, it would be very intriguing in seeing the performance differences for the rigid high torque and mid torque when paired with the 6.0 ah and 9.0 ah octane batteries
It is the same battery chemistry, but they made it flat with custom dimensions instead of round with standardized dimensions. Why would we expect anything else? (Safety reasons prevent them from choosing a more volatile/ higher output battery chemistry.)
Give a battery the size of the 5 amp so we can use it for the rotary and orbital polishers. Right now I use the 8 amps to have enough time between switching batteries
I was buying a dewalt tool recently and I saw that the XR battery line has been renamed to not include the XR branding (and I assume the non-xr batteries are being killed off). This caused a lot of confusion with buyers.
Me, watching this with the 5ah PS video cued up in the next tab: Oh don't you worry TTC dude, you'll get your 220USD battery and you'll get to test it inside of a year.
Battery resistance (internal losses) goes up cold temperatures - the electrolite in the cells starts to freez basically - so the performance drop is expected. In the warm however the resistance only drop a little since the resistance is dominated by the conductor resistance in this case. However the battery will degrade much faster when it is hot. Much like your cell phone battery will die in a year if is is always running hot.
DeWalt screwed up by releaseing the Powerstack battery with a lower amp hour rating only. They then didn't print on the side of the battery the rating and brushed over this fact by taking about how much more power it has over their conventional batteries.
From my experience with LiPo and ion batteries in RC cars, planes and boats if you repeatedly heat cycle that power stack battery often you're gonna puff the cells in it. I see issues with lithium fires in the future, I've seen packs stored and charged wrong burn down garages
Yeah if a 4 amp hour energy stack can work like a 6 amp hour or 8 Amp Hour XR I will be thrilled because I'm running a combination of atomic and detect for my tools
My concern is the lithium pouches have no structural casing or gas vent like the 18650's and 21700's; which means some will inevitably turn into spicy pillows. All Lithium batteries need to vent gases, especially with temp changes.
Can you test the NoCry 20v 1/2 impact on Amazon? It's advertised at 400 Newton meters and the only reason I would suggest it is the NoCry electric screwdriver tested really favorably in project farms testing having more torque than Dewalt. They only currently cost $120 and come with 1 of the 4.0 ah packs.
Pouch cells do have some performance benefits, but I'm willing to bet that DeWalt's deviation from cylindrical cells is more about money or supply than anything. They are probably trying to make it more difficult for people to repair their dead batteries.
Eh... most contractors that make money with their tools aren't going to spend the time to repair batteries. They'll go buy a new pack. Home gamer/DIYers repair them, but that's not the bulk of their customer base.
Very few people repair their batteries, that's a hobbyist thing mostly. I've done it for some friends, but It's actually a pain without a spot welder, because the cells are such a tight fit the solder takes up extra space and you have to shave off some case. These pouch cells would actually be easier to replace. Measure them and they should be available in the exact or a close enough size, pouches are not a proprietary thing.
@@volvo09 - no, I think his talking about Batteries+ repair stores, I’ve taken many batteries to them including power tool batteries at less then half the cost, they replace them with the same or better type.
@@truthserum9157 funny because the batteries+ down the road from me cost more for a replacement cells than just buying a dewalt 2-pack which are regularly onsale....and if you go by Ah, just buy a flexvolt battery when onsale like every other month from toolnut or acmetools or hd.
Not a tool expert, just here researching my first cordless impact. But I am an expert in RC Airplanes. This exact storyline evolved 15 years ago, and I can tell you what happened and happens next: Nickel batteries and brushed motors Then Nickel with Brushless motors Then lithium comes in. Then stacking more and more pouches together and folks flying 100mph+ on electric And then tiny micro brushless lithium ...it all happened in like 3-4 yrs. **When 'POUCH style lithium comes on the scene, NOBODY LOOKS BACK** Everything gets either more powerful, and or smaller, and nobody uses or thinks about cylinder cells ever again.* It's actually kind of weird why power tools are so far behind, all this stuff has been available and mass produced for hobbyists for well over a decade. Anyways, maybe handheld tools aren't as weight sensitive, but maybe they are. Pouch is the future. I have an Atomic/Powerstack kit on order, and depending on need and price, I may never buy a cylinder cell based battery 🔋 Dewalt has 20v ratchet to share this battery with my dcf923, and it's the first platform to offer 'pouch' cells...these were the final deciding factors over Milwaukee or Hercules. Expect more power from smaller sizes. Expect powerstack batteries to get more aH and cheaper price, AND more compact. Expect all other brands to follow the pouch cells, and expect cylinder cells to all but disappear...you'll always be able to rebuild old cylinder cells. Finally, aftermarket will supply the electronics, you'll be able to purchase your own pouch cells and plug-n-play components...it is possible to build / repair your own pouch cell packs.
1. I was told not to store my Dewalt batteries in my truck during the winter and high heat summer day for it would ruin the battery pack. Is this true or will it just affect the battery performance? 2. Does the new power stack batteries react the same as the XR batteries?
not sure they can scale this up due to the heating issues they are going to face with a sandwich battery. dont think I am going to buy one though. I just dont have a use case for it. pretty much all the batteries I have been using lately are the waitley 6 amp.
So looks like a nice compact little piece of 'meh' then. For such a rollout, the results are pretty uninspiring, can't imagine noticing much power difference in use while the mAh is going to be noticeable.
If youre able to ignore the weight advantage thats fine. I jjust know that theres nothing better than light weight if for example attaching some ceiling panels but i keep seeing bean lovers who seem to never do real world work.
Talked to a DeWalt rep at our local tool shop and he said they are coming out with bigger PowerStack batteries this year. I think he said a 5Ah one. I would be interested in that, or even better a FlexVolt power stack. :)
I care a lot more about run time than beans especially with my 3/8, and If I need the beans which I rarely do with what I work on, I bust out the mg725 or my mid torque for lug nuts
@@bj97301 the link is for LiFePO4, w/ nominal voltage of 3.2 and max of 3.6. That would mean max of 18v and nominal of 16V for 5s. Standard, cobalt based, Li-Ion has around 300 recharge cycles and higher energy density than LiFePO4.
@@stanimir4197 I didn’t actually read the whole page. You gotta do your own research. Just google pouch cell cycle count or data sheet. There’s a reason why desalt is claiming 2x the cycle count.
Lithium batteries generally have better performance (charge and discharge) when they are hotter. That’s why in electric vehicles they generally will heat up the batteries to well above a typical room temperature when you are planning to fast charge the battery. But, if they get too hot, the run the risk of melting some of the important isolating bits inside, shorting internally and turning into a fireball.
Keeping up with the other packs with less than half the total capacity does indicate the pouch cells are putting out a lot more current on a per-Amp-hour basis than the cylindrical cells. This is not too surprising considering the entire RC hobby industry runs on pouch cells like this in large part because of their high discharge capabilities, so it would be interesting to see DeWalt expand this line with higher capacity (2P) pouch cell configurations.
There’s a limit to how much the tool will draw from the battery. I bet they will end up designing some new tools that will take advantage of higher current cells. This pack is equivalent in max power output to their existing huge packs - so they would have had no reason to make a tool capable of double the power. They don’t have any 24Ah cylindrical packs :)
I wonder using these on adaptors for other tools would smoke the tools fast, you should try that on the ryobi impact, then if it breaks just warranty it
My curiosity is peaked if this power stack tech allows for more charging cycles then the traditional lithium tech. I think I've heard it's supposed to have more charging cycles. If that's true by a significant margin, then this is looking to be some great tech imo for guys like me that use an impact driver every day all day to build outdoor wood structures with lags and screws. I am a Dewalt platform guy and currently use 4ah batteries as it's a good balance of power, run time, and all day weildability compared to the lighter 2ah batteries which get sapped pretty quick if you have higher torque applications like lag driving.
At least with this cold testing I now know to keep my battery indoors when working on a project to have the best performance.
That one surprised us, knew it would be lower but yeesh!

I think that little power stack battery is a perfect match for the little DCF921 1/2" power house. But if you have a high torque impact gun, why not spend the same money for a heavier battery that will balance the tool in your hand and run longer? Thanks for doing this testing! Glad to see DeWalt innovating.
Thank you for your (as always) great analysis and testing.
I'm really sick of 90% of the tool based youtube channels reading off DeWalts marketing talking points and creaming their pants over this battery without doing any real testing or showing any skepticism.
Its an interesting technology... but really expensive for the capacity. I think its overhyped.
dewalt CLAIMS that it has twice the total charge cycle life, I guess real world time testing will tell.
relax karen. you can get these batteries for free with quite a few tools if you just look around online... they even have those deals in stores.
@@squirts1 I got mine for free while purchasing a hammer drill solo. pretty cool.
@@squirts1 you use them yet? Just impulsively bought 4 of them on a killer deal. From the testing I've seen it'll probably be primarily for my impact driver and standard drill, probably not a skillsaw or jigsaw though
Smashed that thumbs up for the excellent alliteration in this video.
Thank you for another amazing video, just curious if you guys would consider testing the cross brand adapters that are out there? The ones that allow you to put a battery from one brand on the body of another?
Thanks guys keep up the good work
So far all my cordless tools are de Walt but I don't like the xr planner so I have just bought a adapter to try and use Makita brushless planner and hopefully run it with my de Walt battery's so I'd be interested in a cross brand video as well
@@briangordon1767 ua-cam.com/video/WgJI8Ikrd6Y/v-deo.htmlsi=P8BXwmyOa8YQePm7
It arrived! Definitely some useful information, I feel like its more of an overview, but there are a lot of brands out there to try and crossover with
I have plenty of batteries but I want one of these for my 887 impact driver for general purpose work. I just don't want to pay for it haha.
I have the 60v circular saw and let me tell you that is the way to go for a circular saw. It's the one that convinced me to start keeping my corded saw stored in my garage and trust battery operated in my truck completely. I did also get the Flex volt hammer drill kit so I also have a spare 60v battery so it's fine having a backup.
Good blades are a must with battery saws though, while I can use my old corded DW364 with several teeth missing from the blade, it doesn't care it just plows right on through, so I do sometimes miss that kind of power though.
This is why when we fly drones in the cold winter months we pocket our lipo's in our coat jackets to keep it warm so it doesn't preform like crap when it's cold. The higher the C rating on a lipo the higher the discharge rate will be. meaning more power.
The higher the C rating means it can handle more amps being pulled from the battery without damaging the battery. Amps is pulled, voltage is pushed. Not being sarcastic or mean, or anything like that.
I'm a big RC nerd. Custom built racing vehicles. Also fly some aircraft and drones.
Love my replica tanks that shoot airsoft too. Lol
Another great test! Looking forward to more and better in 2022! 👍Your channel rocks! Happy Holidays!
They are on Amazon for $66 with a charger right now for prime day
I've been waiting for this video to arrive. I like the idea a lot, but I doubt I'll buy any until/unless they put out higher capacity versions
Great tests. I was looking for this exact test and here it is. Great work team TTC
Seems like a perfect fit for Atomic tools for everyday type uses, then switch over to a 5.0 or similar if you have the rate project that's actually going to need the runtime. And now you can go from tiny flexstack all the way to the 15Ah Flexvolt monster in the same tool family. If only SBD didn't charge such crazy prices for ALL of their batteries (highest $/Wh of any of the major brands IIRC) I might be tempted to switch over.
I only buy batteries on black Friday sales
they have really good sales on their stuff if you can find them, i got a dcf921 with a 5ah battery for free through home depot. then i bought the powerstack starter kit and got a free atomic multitool with it.
Wow. Amazing video! Thoroughly tests. Thank you for that!
Loving the tremendous temperature alliterations
Hello again Torque Test channel
Thank you for another Great Video. Thank you for the research the capabilities of the Power Stack battery. I am looking forward to seeing more. Again thank you and Merry Christmas to you and your family.
Merry Christmas George
I'm just here to say that I appreciate the alliteration.
For high torque applications 6S x LiFePO4 would make more sense - similar voltage, much higher discharge rate, possible high charge up to ~80% (e.g. 15-18mins for 80%). It will have lower capacity but lasts way longer, degrades much slower... and no cobalt needed. They will be partly supported by existing charges but not fully...
Come for the torque tests; stay for the alliteration.
I agree. Definitely not going to spend money on these for the little benefit. Waiting to see higher Ah to see the real comparisons. Thank you for showing us the numbers
Probably best reserved for tools with a shorter operation time and moderate current draws. The close packing of the cells will punish the inner cells with heat buildup leading to uneven individual cell performance across the entire pack
I really like the flat/pouch-cell batteries. The goal was to downsize the battery and keep the power or improve it.
I believe they succeeded.
British release in March is with the 2.0 power stack 👌 what the dcf850 was originally built around.... for me it can't come soon enough I have it on pre order with the 2 2ah batteries and the new ps charger for £299
Happy to see you started with cold testing before hot testing. ☀🌡❄
Batteries, for the most part, do not like extreme temperature changes. I live in Arizona, and the majority of vehicle batteries I replace are when the temperature dips down. Granted, vehicle batteries are not the same as power tool batteries, but your testing proves the same point. Batteries on their way out could start a vehicle in the heat of summer, but would fail to start in colder conditions.
Working performance will be affected by temperature.
Thanks for your time (and money) spent on getting real results!
I want to see the power stack versus the small DeWalt batteries (2ah or 3ah).
That is this battery's true competition. Similar size and runtime. Bump up to the 4ah or 5ah if runtime is important.
Great test on the power stack. Thanks for sharing. I think this may end up being the future of packs instead of the 21700's? Will have to do better with run time though...
Very interesting... I was wondering when power tools would implement a pouch battery.
But, like you said, I want more capacity. The slim pack is great for a small light tool though. At least it dosen't sacrifice performance to get you that... But you pay for it.
I saw the 2-pack of 1.7’s on Woot today for I think $116. Glad I watched this video before pulling the trigger on getting these. I’m looking for runtime for my DeWalt weed trimmer and leaf blower, not so much looking for more power for my drill / impact. I think that price is way down from a year ago, which suggests that maybe people have begun to see through the hype of these batteries.
I’m hoping to take advantage of early-adopters and Greater Fools who bought the Powerstacks and are selling off their relatively new-ish 5 Ah XR batteries cheaply.
I remember when I first started watching your channel. I saw you holding up some kind of cordless impact up and it made the pneumatic impact sound and I rewinded it like 10 time trying to understand how the hell that cordless impact made that sound🤣🤣🤣
Recommend Welzh Werkzeug Air Impact Wrench Gun 1/2 Drive Mini Beast 1350NM 1.2KG Stubby upgraded my snap on mg725 and it blows it out of the water on Amazon for £150 and couldn’t be more impressed
You’re doing the working classes Due diligence my friend !!
This might be good for the palm sanders. The small 1.5 or 2.0 ones are all I use with that so it's not so heavy.
The lifetime of these packs is going to be interesting to see. Those flat packs crammed in there like that could generate quite a bit of heat and reduce the life of the cells over time. Especially with a low ah pack that needs to be charged/discharged more often.
They'll generate overall less heat than li-ion cells because of the lower internal resistance, no?
My m12 6.0s and boss's lxt 5.0s generally last all day in our impacts/drills. The added weight of a standard pack is a better trade off over having to have 3 batteries for the day with the added cost too.
Would absolutely love to see this powerstack and the 15ah with adapter to the ridgid octane high torque former king, then on the current king dcf900
Great content, keep it up. This is what I like to see.
If possible, it would be very intriguing in seeing the performance differences for the rigid high torque and mid torque when paired with the 6.0 ah and 9.0 ah octane batteries
this is a great channel i love the content guys !!
It is the same battery chemistry, but they made it flat with custom dimensions instead of round with standardized dimensions. Why would we expect anything else? (Safety reasons prevent them from choosing a more volatile/ higher output battery chemistry.)
hell yeah I knew yall would come thru on the powerstack
Something about using the moniker “freedom” for Fahrenheit really broke kayfabe for me.
I was thinking I was the only person to catch that. It made me laugh.
I saw what I needed from Dewalt at 12:09
Give a battery the size of the 5 amp so we can use it for the rotary and orbital polishers. Right now I use the 8 amps to have enough time between switching batteries
I was buying a dewalt tool recently and I saw that the XR battery line has been renamed to not include the XR branding (and I assume the non-xr batteries are being killed off). This caused a lot of confusion with buyers.
XR was originally used to designate brushless tools
They really should have kept the XR branding off the batteries from the beginning.
Me, watching this with the 5ah PS video cued up in the next tab: Oh don't you worry TTC dude, you'll get your 220USD battery and you'll get to test it inside of a year.
Battery resistance (internal losses) goes up cold temperatures - the electrolite in the cells starts to freez basically - so the performance drop is expected. In the warm however the resistance only drop a little since the resistance is dominated by the conductor resistance in this case. However the battery will degrade much faster when it is hot. Much like your cell phone battery will die in a year if is is always running hot.
DeWalt screwed up by releaseing the Powerstack battery with a lower amp hour rating only. They then didn't print on the side of the battery the rating and brushed over this fact by taking about how much more power it has over their conventional batteries.
The 5Ah Powerstack DCBP518-XJ has launched in the EMEA/ANZ regions, no word on NA release yet.
@@drivingmemad7127 Thanks for the update. 👍
Will the power stack technology be scaled up to replace the larger capacity batteries for the lawnmowers and yard equipment?
From my experience with LiPo and ion batteries in RC cars, planes and boats if you repeatedly heat cycle that power stack battery often you're gonna puff the cells in it. I see issues with lithium fires in the future, I've seen packs stored and charged wrong burn down garages
it's not a lipo... it's not an RC car battery...
Hay u should definitely look into the Bosch freak gdx18v-1860cn
Will do!
Yeah if a 4 amp hour energy stack can work like a 6 amp hour or 8 Amp Hour XR I will be thrilled because I'm running a combination of atomic and detect for my tools
My concern is the lithium pouches have no structural casing or gas vent like the 18650's and 21700's; which means some will inevitably turn into spicy pillows. All Lithium batteries need to vent gases, especially with temp changes.
Cold test metabo hpt multivolt batteries 4ah specifically. I had two die on me in the cold.
Can you test the NoCry 20v 1/2 impact on Amazon? It's advertised at 400 Newton meters and the only reason I would suggest it is the NoCry electric screwdriver tested really favorably in project farms testing having more torque than Dewalt.
They only currently cost $120 and come with 1 of the 4.0 ah packs.
Awesome stuff as usual....except that blue font🤣
Pouch cells do have some performance benefits, but I'm willing to bet that DeWalt's deviation from cylindrical cells is more about money or supply than anything. They are probably trying to make it more difficult for people to repair their dead batteries.
Eh... most contractors that make money with their tools aren't going to spend the time to repair batteries. They'll go buy a new pack. Home gamer/DIYers repair them, but that's not the bulk of their customer base.
Very few people repair their batteries, that's a hobbyist thing mostly.
I've done it for some friends, but It's actually a pain without a spot welder, because the cells are such a tight fit the solder takes up extra space and you have to shave off some case.
These pouch cells would actually be easier to replace. Measure them and they should be available in the exact or a close enough size, pouches are not a proprietary thing.
@@volvo09 - no, I think his talking about Batteries+ repair stores, I’ve taken many batteries to them including power tool batteries at less then half the cost, they replace them with the same or better type.
@@truthserum9157 do you have a local place or online. A few online places I have looked it wasn't much cheaper than a new one
@@truthserum9157 funny because the batteries+ down the road from me cost more for a replacement cells than just buying a dewalt 2-pack which are regularly onsale....and if you go by Ah, just buy a flexvolt battery when onsale like every other month from toolnut or acmetools or hd.
Not a tool expert, just here researching my first cordless impact.
But I am an expert in RC Airplanes.
This exact storyline evolved 15 years ago, and I can tell you what happened and happens next:
Nickel batteries and brushed motors
Then Nickel with Brushless motors
Then lithium comes in.
Then stacking more and more pouches together and folks flying 100mph+ on electric
And then tiny micro brushless lithium
...it all happened in like 3-4 yrs.
**When 'POUCH style lithium comes on the scene, NOBODY LOOKS BACK**
Everything gets either more powerful, and or smaller, and nobody uses or thinks about cylinder cells ever again.*
It's actually kind of weird why power tools are so far behind, all this stuff has been available and mass produced for hobbyists for well over a decade.
Anyways, maybe handheld tools aren't as weight sensitive, but maybe they are.
Pouch is the future.
I have an Atomic/Powerstack kit on order, and depending on need and price, I may never buy a cylinder cell based battery 🔋
Dewalt has 20v ratchet to share this battery with my dcf923, and it's the first platform to offer 'pouch' cells...these were the final deciding factors over Milwaukee or Hercules.
Expect more power from smaller sizes.
Expect powerstack batteries to get more aH and cheaper price, AND more compact.
Expect all other brands to follow the pouch cells, and expect cylinder cells to all but disappear...you'll always be able to rebuild old cylinder cells.
Finally, aftermarket will supply the electronics, you'll be able to purchase your own pouch cells and plug-n-play components...it is possible to build / repair your own pouch cell packs.
Great work, thank you for being so thorough
I assume they will come out with bigger ones soon even when they first dropped the 60v system they only released the 6ah for a while
And thanks as always for a great video.
Think heat would become a problem in 4Ah/2p configuration
1. I was told not to store my Dewalt batteries in my truck during the winter and high heat summer day for it would ruin the battery pack. Is this true or will it just affect the battery performance?
2. Does the new power stack batteries react the same as the XR batteries?
not sure they can scale this up due to the heating issues they are going to face with a sandwich battery. dont think I am going to buy one though. I just dont have a use case for it. pretty much all the batteries I have been using lately are the waitley 6 amp.
Now I want to see how the cordless tools would do running directly off the wall via adapter.
So looks like a nice compact little piece of 'meh' then. For such a rollout, the results are pretty uninspiring, can't imagine noticing much power difference in use while the mAh is going to be noticeable.
Exactly!! All marketing to sell more shit.
If youre able to ignore the weight advantage thats fine. I jjust know that theres nothing better than light weight if for example attaching some ceiling panels but i keep seeing bean lovers who seem to never do real world work.
Talked to a DeWalt rep at our local tool shop and he said they are coming out with bigger PowerStack batteries this year. I think he said a 5Ah one. I would be interested in that, or even better a FlexVolt power stack. :)
Did they specify on when?
Unfortunately no.
I care a lot more about run time than beans especially with my 3/8, and If I need the beans which I rarely do with what I work on, I bust out the mg725 or my mid torque for lug nuts
Have u done a video on brushed impacts with different sized batteries and maybe put them against brushless too
Another benefit that’s worth mentioning is the number of charge cycles. We can probably expect 1000 or more from the power stack.
Where did you get that info - it'd mean different chemistry, i.e. LiFePO4?
@@bj97301 the link is for LiFePO4, w/ nominal voltage of 3.2 and max of 3.6. That would mean max of 18v and nominal of 16V for 5s. Standard, cobalt based, Li-Ion has around 300 recharge cycles and higher energy density than LiFePO4.
@@stanimir4197 I didn’t actually read the whole page. You gotta do your own research. Just google pouch cell cycle count or data sheet. There’s a reason why desalt is claiming 2x the cycle count.
Lithium batteries generally have better performance (charge and discharge) when they are hotter. That’s why in electric vehicles they generally will heat up the batteries to well above a typical room temperature when you are planning to fast charge the battery. But, if they get too hot, the run the risk of melting some of the important isolating bits inside, shorting internally and turning into a fireball.
I'm still rocking the Makita xdt11 4 pole impact driver. Feels better made then newer stuff.
You should try Jet air tools. Never tried them and haven't heard much about them.
Keeping up with the other packs with less than half the total capacity does indicate the pouch cells are putting out a lot more current on a per-Amp-hour basis than the cylindrical cells. This is not too surprising considering the entire RC hobby industry runs on pouch cells like this in large part because of their high discharge capabilities, so it would be interesting to see DeWalt expand this line with higher capacity (2P) pouch cell configurations.
There’s a limit to how much the tool will draw from the battery. I bet they will end up designing some new tools that will take advantage of higher current cells.
This pack is equivalent in max power output to their existing huge packs - so they would have had no reason to make a tool capable of double the power. They don’t have any 24Ah cylindrical packs :)
Why are we waiting to see from “Flex” concerning a larger power stack pack. Shouldn’t we be waiting to see from Dewalt/Stanley Black and Decker?
Flex has stacked lithium coming out. Rumored larger capacities
I wonder using these on adaptors for other tools would smoke the tools fast, you should try that on the ryobi impact, then if it breaks just warranty it
I've noticed a severe drop off in speed for my high speed m12 ratchet if it gets below 35-40 degrees Fahrenheit
Did they figure out a way to minimize the chance for the pouches to catch fire?
let s see what it s got inside. would you like to open it? i am curious about the producer and the technology
My curiosity is peaked if this power stack tech allows for more charging cycles then the traditional lithium tech. I think I've heard it's supposed to have more charging cycles. If that's true by a significant margin, then this is looking to be some great tech imo for guys like me that use an impact driver every day all day to build outdoor wood structures with lags and screws. I am a Dewalt platform guy and currently use 4ah batteries as it's a good balance of power, run time, and all day weildability compared to the lighter 2ah batteries which get sapped pretty quick if you have higher torque applications like lag driving.
