Which Dewalt Battery Option is Right for Your Power Tools?
In the last two videos, we compared the smaller and larger Dewalt batteries to showcase the different voltages available in various tools. Today, we’re testing a small Dewalt Atomic impact driver by drilling different screws into wood and testing the voltage of each battery to determine which one will be the best option for your uses.
To conduct the test, two wires were used, and the voltage was measured to observe how much power the tool consumes from the batteries. We designated the batteries based on their amp hour rating, even though the voltage drop is based on the battery’s cells and not the amp hour.
The tests conducted showed that the 2 Amp Hour Compact battery consistently had a voltage of 16 volts, while the 1.7 Amp Hour Power Stack battery stayed in the mid-17s. The Three Amp Hour Compact battery consistently stayed in the high 17s to low 18s, and the 4 Amp Hour Compact almost made it down to 17.2 volts.
The 5 Amp Hour XR battery showed low 18s and high 17s, while the 5 Amp Hour Power Stack never made it out of the 18s. The 6 Amp Hour 20 Volt battery never made it out of the 18s, but the 8 Amp Hour XR 20 Volt battery did surpass 18 volts. These batteries performed well on a small impact tool like the Dewalt Atomic.
Lastly, to everyone’s surprise, the tiny Dewalt Atomic’s voltage sustained mid to high 19s even after being tested on a 9 Amp Hour Flexvolt battery.
From the tests, it is evident that although the 6 Amp Hour battery has more power, it was too powerful for the small tool’s application. Therefore, users seeking a good balance between runtime and performance should consider the 3-4 Amp Hour and 5 Amp Hour Power Stack batteries, respectively.
Furthermore, DeWalt is preparing to launch a kit that includes a 7 and 1/4 inch circular saw and a 5 Amp Hour battery. The performance of this kit remains to be seen, but once we get our hands on the circular saw, we’ll conduct similar tests and let you know our findings.

It be amazing battery maybe next month when I've more money
Like anything, rite tool for the job, like you said… in my application id say min. 50% -75% over head, well… i want the smallest lightest i can get away with, FOOT POUNDS are irrelevant after 75-100 morel than enough, i need Reliability, good modes, good ergonomix, light weight.. LIGHT WEIGHT and decent runtime. i could care less about ultimate torque as All modern impact drivers will spin out, strip out, cam out and snap the heads off fasteners in my application, rarely past 10-24, maybe…MAYBE a few 12-24 and a few 1/4 20s.
Thank you for your great videos! One of my favorite channels to watch! Always have good reviews! 🙏🙏
I have been using the 1.7 powerstack on the stubby impact. I love that thing. its my goto for around the house.
Well you'll see a 9 on my impact driver. Installing overhead doors when there's steel jambs. I'm changing my 5 every half hour plus it struggles to provide enough power for the jamb drillers especially when it's getting low
Will you compare batteries with 20v saw?
You nicely skim over the weight of the 5ah powerstack vs the 5ah xr.
Cmon man 🍎/ 🍋 vs 🍒
I ordered the PowerStack 5ah & when it arrived I was disappointed that it was much larger than expected. I returned it & might buy it again when the price comes down…
Dollar for dollar and pound for pound, I'll definitely be buying more 6Ah XR batteries. The Powerstack is impressive but not significantly better than the 6Ah and certainly not enough to justify the price difference.
I wish they made its shape more in line with the 5ah xr battery. Less long and more deep? The proportions just kind of seem off to me. But I guess who cares about aesthetics on a power tool.
I run mostly Makita but my company outfits me with some DeWalt cordless tools and I have to say, getting the batteries off the Dewalt tools is not nearly as smooth as my Makitas. Does anyone else have this problem? They stick, they don’t slide nice and the biggest complaint I have is more of the tools than not is the battery indicator facing in a direction where you can’t check it while on the tool. Almost as bad as Milwaukee’s 12 V lineup where you have to put the battery in the tool to check it level.
If power stack is to great, why do they not refer to Amp-Hours anymore with the PS?
Everything was AH now they want to ignore it.
Great Comparison!
Can you do 12v lines as well like Makita CXT and Dewalt 12v Max?
I could see that Milwaukee M12 would be harder to get the connection on.
9ah flex volt on an impact driver, 1-1/4 drywall screw. Hold My Beer.
2.0 compact is always the answer for smaller tools. 1/3 to 1/4 the price, especially used and delivers 90% of the power.
Nice comparison Brian, use the 6AH and 3.0 the. Most myself. I do not have any power stack yet but am considering it.
I JUST BOUGHT the 7 1/4” flex volt circular saw with the 9ah FlexVolt battery, kit model DCS578X1…if they give you the same saw with a 5ah power stack battery…I think I’m going to return mine and pay the difference…duuuuh!
Did you use the DeWalt Atomic Compact Impact Driver model DCF850 for this test?
I see batteries getting bigger and bigger. Before long a person won't be able to hold a drill up. Lol
Thank you for the comparison. Most of the comparisons I've seen so far, folks are freaking out because it's so much bigger than the 1.7. Your review does a wonderful comparison to the entire line, and shows me size to power is excellent, it's all about how much the user wants to spend for their intended application. Thank You!
great stuff man, thanks for the hard work…..can you test makitas like this?
it's your saw horse lol…
Yeah maybe the power stack is the ultimate till the next drop but at the cost you could run a whole bunch of previous gen batteries for the cost of one of them power stacks
Look foward you test the stack in the cir saw !
😎🛠️😎🛠️😎
I have the 1.7 power stack and it's great for my impact wrench but idk how I feel dropping over $300 for 2 5ah power stacks. Probably wait for a nice sale or regular price drop
