How would they last as long as a 4ah???? They clearly are a 1.7 ah. Most of the reason I love them is because of their high power output. Great for mechanics, not so useful for construction
not sure about the battery lights, but they're just supposed to deliver a higher more stable voltage, equivalent to that of a four or five amp hour battery. so they would give the tools the same punch, but be smaller and lighter. not supposed to last longer 🤷♂️
For anyone that's interested, the lithium power stack has a lower internal resistance, which is responsible for its ability to output more power at one time than another battery. It's not going to last as long "duh" bc its a lower overal capacity. Idk why hes pushing the battery button while running the tool, of course its gonna have a voltage drop.
Its 1.7 Amp battery that holds the 20v max longer then the other XR batteries when you use it so it has the size of a small battery but you get the voltage power of say a 5 Ah
You 100% got a defective Power Stack. I would look into returning for a replacement. I do agree they definitely don't last as long as the 5ah run time wise. However, they do still pack a punch with the initial power especially considering the power to weight ratio. Also charge time is pretty darn quick with them
They still shouldn’t blank out like that on a full charge I’ve had mine for over a year and they’re great. I’ve put them on every power tool desalt makes and they don’t act like that. I’m sure he got defective ones
@@jnmc-vx4fwits a stacked lithium cell. Power output is comparable to a 4/5ah. Stacked cells are more efficient and power dense than 18650/21700 cells. It’s a better battery period. Step up the 5ah powerstack and they’ve been tested and confirmed to be as powerful as it’s 12ah 21700 counterpart .
I agree! I tried mine yesterday and they literally ran out faster than my 1.5 aH battery! Junk! And for consistency, it was a constant steady load and it happened on both Powerstack Batteries. I was inflating a 523 cubic foot globe. Took 43 minutes for those interested.
It outputs at a higher power similar to a 4/5ah battery. You’re not going to see a similar runtime. The tech behind the pouch cells allows for a lower impedance as opposed to standard lithium ion 1860 cells
Thank you. I’ve seen enough comments on this video similar to mine that I’m going to say these were kind of a flop… some say they are good but, tooo many people have said the same thing as me……
Dude , this guy is a moron. He’s comparing a 1.7 ah powerstack to a 4ah battery . Of course it doesn’t last as long it’s lesss then half the ah of a 4ah battery. It’s comparable to a 2ah battery but has twice the power . Dewalt does make a 5 ah powerstack battery that compares to the regular 5ah except it has 50% more power then the reg 5ah
I like them, they will put out constant power till they run out, where as the normal start dieing as the battery gets half way, you can hear the reduced power output.
The powerstack will maintain a voltage comparable to a 4 or 5 ah XR battery. I use my 1.7ah PS on my 20v atomic bandsaw and impact where they don’t use a ton of power and I appreciate the weight savings over a larger battery. For high amp draw applications like a vacuum or hammer drill I’ll stick with a 6ah XR battery.
Still using my 2014 18v XRP tools and batteries. 10 years later. DeWalt went to absolute Shite when porter cable took over. All my friends with the 20v stuff are already looking to replace.
When I graduates high school in 07 my dad gave me a 12v impact. That thing lasted me until 2023 when I lost it in a fire due to an idiot I was trying to help out.
Your friends with the lithium(and likely brushless) stuff have probably used their tools/batteries a lot more than you have. Apparently you don't understand that batteries can only be charged/discharged so many times before they no longer hold any practical level of charge. The battery degrades, and charge capacity drops, every charge cycle, necessarily. And with nicad especially, not only does charge capacity drop, but performsce also begins to significantly drop after just a couple or few hundred charge cycles
@@gregorsamsa1364 obviously i replace the batteries when they stop holding charges.. i mean the tools themselves.. my new " atomic brushless " failed years before my 18v (dewalt) stuff did. The real DeWalt stuff, not the porter cable stuff
Yeah I watched your video bud I'm here to tell you. you got 2 defective batteries man thsts for sure because I been using the 1.7 power stack an the 5ah power stack an they definitely work great man way much more power I've seen them hang with a 15ah battery you got 2 broken batterys
The entire point of pouch cell batteries is to have lots of power in a tiny volume for weight/space uses while sacrificing run time... These small ones are only 1.7 AH and are dumping amperage similar to a 4-5ah 18650 cell battery... They will last about 1/5 the time in high demand tools. They have a very niche use, like lightweight above head work in a drill/impact/oscillating tool/jigsaw for short periods... Honestly I got them in a buy one get one deal and only use them in my compact impact and compact drill... But the 5ah Powerstack is a beast for over waist use in recips/circular saws/grinders etc. but the same goes for power similar to a flexvolt or 8ah in those tools, but a fraction of the runtime... They definitely aren't a go-to do all battery, specifically designed for being good at certain tasks vs. typically 18650/21700 cell Dewalt batteries... Apparently nobody ever reads the package information or checks the AH on the back of the pack or box 🤷♂️🤦♂️
I bought a two pack for $200 and got a free power tool that was worth that much out of it.. so I'm not complaining. 2 small extra batteries to have laying around... PS it's my first dewalt purchase EVER (Been a milwaukee dude 12years now)
the powerstack is a high output battery it dumps power better making tools stronger but the ampage / watt hours on the battery is still the same whether its powerstack or not. the power claims and runtime claims are against its equivalent i.e 2 amp the real selling point is the charge cycles now you may have had a faulty battery or it was damaged in some way. i have both and can tell from experience the powerstacks are very efficient batteries if used for their designed purpose. if a tool has a fixed power consumption then the runtime will be the same i.e hoovers radios etc anything with a motor and varying speed has a variance in current draw and that will see a benefit from a cooler battery and voltage sap as the batttery empties its charge. there is also not alot of voltage sag near the end of charge which you'll notice on xr batteries as loosing its power output in th4e tool near empty. best thing to see like for like comparison to the 4 / 5amp batteries your using is the 5ah powerstack mine is like injecting the xr with steroids in terms of power
This is why I buy and use mostly Bauer tools from harbor freight because they're a lot more affordable and if the higher end Dewalt tools and batteries like yours are supposed to be so much better but they don't even work that great then what's the point in spending all that extra money?
Just bought today, wish I saw this video first. Don't work much better than my original smaller 2ah but are a super tight fit requiring much effort to remove and replace. No fun when your up on a ladder. Seems like tolerance are off. These ones are made in China my old battery is not. Dewalt should be ashamed. Doesn't Dewalt investigate or care anymore. I've seem many other comments with same issue.
My brother in christ, 1.7ah is less than 1/2 of a 5ah. The man benefit of these batteries is that they're slim and compact, but they out out as much current as a 5ah battery. So no, they will not last as long. But compare them to a regular 2ah battery in a high demand load like a circ saw, and those PS will run circles around them.
Why get 1.7ah when you could get the 5ah power stack if longetevity is an issue??? They put out just as much power as the old 5ah but just for a shorter amount of time. Plus they charge super quick and getting a 2 pack is ideal so that you can charge one while the other is being ran. Ideal for smaller at home projects tho while at the same time it packing a punch 👌🏽 If you need more heavy duty shit, 8ah to flex volt is the better options…
Idk why they even sold a 1.7 AH. I got one for free with the atomic impact. I do commercial HVAC and it couldn’t even last a day of doing 3/4” 5/16 screws. After a couple charges the “fuel” gauge quit working. I ended up returning them both. I asked the exterior guys how their 5 ah power stack was holding up. They said light quit working and the old 5ah XR are better.
It is absolutely amazing to me how so many people do not realize that none of these battery packs maintain their full peak voltage output as they discharge that they carry when they are fully charged. The entire point of the power stag batteries is to be able to get the same high voltage output from a much smaller battery that stays more consistent as it is discharging, that you would otherwise have to use a much larger fully charged battery to get. I mean it's fine that people don't know that but what I don't understand is why so many people are actually surprised or upset and thinking these batteries are garbage for not lasting as long as another battery that is literally two or sometimes three times the size as their power stack pack. What is it I'm out the words power stack that makes a person think 1.7 ah All of a sudden equals five ah? I just don't understand at all why power snack makes people's brains think it means times two whatever the Ah rating is on their previous batter. Its ridiculous
So i suppose what he is saying is still half relevant if true. If not as powerful as the 5a battery it really does fail on all fronts. Obviously not going to last as long as a 5a
lol dude its a 1.7 ah, the powerstacks claim is that it can dump as hard as the 5ah. If you watch torque test channels powerstack reviews they will show you that you get same power out of it not same run time. The 5ah powerstack is where its at, even beats the 9ah flexvolts.
Bad pack. Its like a damn epidemic. Dewalt got screwed and some china man is laughing his ass off. They should and will absolutely stomp the og batteries when they gey this figured out
You dont know anything about electrical. Bigger batt can provide more amp than smaller one, the power stack have compact size but can provide amp equally to 5ah or 6ah batts with the sacrifice of usage time
You sound surprised that they dont last half as long as a 5ah when 1.7 is less than half of 5
Lmfao. Ppl really don't seem to get this concept. It's actually annoying
Can you imagine how easy it would have been for dewalt to put the amp hour on the side
Bro this comment was hilarious.
Wtf I can't believe that 1.7 is less than 2, oh well, 👀

They will not last as long they don't have as much juice but they put out as much juice as a 5 amp which means they're going to depleat quickly.
