I'd just like to point out that flexy9 has built-in gravity assist.

[DavidStockton-un]

Fantastic and practical comparison. Thanks for doing this! I've really been figuring out what to do for our heat gun and our big rotary hammer drill. The FlexVolt and PS seem to be the standouts. Very interesting about using Milwaukee batteries on Dewalt tools...never even considered that!

Pouch type LiPo cells (the type the PowerStack use, I believe) can usually deliver more current than cylindrical cells as they have lower internal resistance, due to the cell chemistry and the way the cells are designed. For two batteries of the same energy capacity rating (5Ah, 18/20V in this case), a pouch cell would be able to deliver higher current more efficiently (less energy wasted as heat in the battery, more power delivered to the tool). So when DeWalt claim "twice the power" they presumably are referring to that instantaneous power. For relatively modest loads, e.g. the vacuum, the current (power) delivery is fine for both battery types, so you get the same run time as they both contain the same energy: i.e. 5Ah x 18/20V.

Thanks a lot for the test... It's really inspiring and makes me sure to still use my XR 20v 5Ah... Postpone to buy the power stack or flex volt.. 👌🏼😁

Dewalts should start putting that rubber bottom on all their batteries,

I use dewalt 5amp and flexvolt 6 and 9amp, they just seem to work well in most tools

Amazed at this man's video creation

[Surmoka]

I don't know why this channel doesn't have many more subs. This is really cool. Technically decent descriptions and testing approach. This channel is out of the box better than 90% of other review channels on their best day.
One addition: the reason why Milfuckee tools run better on Default batteries (or, any battery with a non-matching tool) is because the adapter doesn't have the thermistor pin connected as they have different values for each brand. So, unless the battery shuts itself down to prevent overheating, the tool won't do it.

Great vid, all the stuff these days just seems so negligibly similar, particularly if you're low use or homeowner it doesn't matter. If you're in the trades just buy 3 high amp batters and there's not a thing to worry about.

[colinwhitehead]

Thank you for looking into battery durability.
Brilliant to see if the manufacturer has there products correctly labelled 👍😎

[Penguin]

Those power stacks really shine through in high torque tools that would otherwise stall out with smaller batteries- saws and drills using hole saws specifically. The 1.7 is light too for smaller applications like bandsaws or paired with atomic line tools.

[plainoldme]

Wider is a problem with tools that use belt clips, , , not sure if they make different clips to compensate for the wide ones

[discreetwolf]

Is the XR battery comparable to a lithium battery? I know nothing about tools and just want to get my man a really good battery. He's brought the dewalt lithiumbatteries up a lot just unsure what would be the better choice. Loved your review and testing. Thank you!

[MrNfury]

Great video, clearly delivered.
Thank you from 🇦🇺👍🍒

[SavedByFaithInJesus]

6:27 Milwaukee batts will fit Dewalt tools??? Please explain.... and use small words.... What did I miss?
Edit: Thank you for this video. Excellent work. I do appreciate the demos and testing examples. I have All dewalt (been a dewalt guy since the OG 18volt came out back in 1995/96)

[Boris_Chang]

I have a bunch of older DeWalt Max batteries: will these work with the recent drills (such as the 800 and 805)?

[BenJamin-oukd]

I use the 20v heat gun to test run time

[davidalford]

Have you done a video comparing the 60v dewalt circular saw? I have had mine, running 9ah batteries, (very rarely using 6ah) for about 3 years? My makita lxt has become a dust collector.

[alfonsoguzman]

Great video... Justo one question; the 20v has to stay on the charger for 8 hrs each time o just the first time?

[upnorth]

I'll take the compact power stack all day every day on an impact driver. No need to lug a huge battery all day long. Run time is not hindered because you can have multiple batteries charged and ready to go.

Can we all just admit that, our fathers tools were inferior to what we’ve been blessed with! Majority of buyers will never use these tools to their true potential in the end. For me, I have DEWALT tools, and a ton of money invested, so I will never switch. I don’t blame Milwaukee, ryobi, makita guys, etc. either.
