🔥 DeWalt POWERSTACK vs 15AH FLEXVOLT ⚡ DCF840 vs DCF850

The new DeWalt Powerstack and 15aH Flexvolt battery battle it out on the DCF840 and DCF850 Atomic impact drivers! We also throw the 21700 cell 4aH slim battery pack in the mix to take on the 18650 cells in the Flexvolt and lithium pouch cells in the Powerstack.

[@markhedquist9597]

Just a thought... Whenever I watch these comparison videos there always seems to be the issue of not being able to know when the lag screw is fully seated because of the socket blocking the view. Maybe a big fender washer would help in these tests. You could see the washer seat and then you would know the test is done. 🤔

[@PhillyFixed]

Hmm, that's not a bad idea! The only trick would be keeping the socket from bottoming out on the workpiece, otherwise it would be hard to tell if it was the socket pressing down on the washer or the fastener. I'll mess around with it a bit!

@@bossmanz28 i am using a 20” chainsaw and was cutting up a maple tree. The charger that came with the kit is the dcb115. Do they make a better one? Awful small looking charger for such a huge battery. My greenworks 80-volt charger is about twice as big as the dewalt and will charge my 80-volt battery in one hour and give me almost an hour of nonstop push mowing and it is only a 4 amp battery. My 56volt 12 ampEGO charges in one hour also. Unless the chainsaw just uses that much juice. I have no flashlight to test with as my carpentry stuff is all milwaukee M12 and M 18. I bought the dewalt line of outdoor tools as it seemed better than stihl and echo.

[@bossmanz28]

@@sacredcowtipper1378 ive heard the 20" chainsaw really eats batteries even the 15ah via workshop addict. Thats how i got mine but i havent pushed the chainsaw like crazy yet. And yes there are a few better chargers. Yellow chargers are the fastest. The more common yellow charger charges the 15ah in think 2 hours but i could be mistaken and then there is an even faster 1 but im not sure how much faster that is. 1 is rated as an 8amp charge output rate while the other is a 12amp charge output rate. The 8amp one charges a 6ah in 1 hour but a 12ah in an 1 hr and 40. Not sure how it works but those are the specs. The outdoor power tools all come with normal chargers cuz compared to construction tools dewalt does give you a better value on the battery purchase so they give you a crappier charger. The main reason i got the 20" chainsaw was jus for the 15ah. Got a discount deal and got it for 475 with the 15ah while the bare tool of the saw and the charger are lile 380 to 400 each Edit theres also a 4 port yellow rapid charger all at the same time that is the 8 amp output. Thats what i have. And its the only yellow charger that will also charge 12v if thay matters to you. All black chargers do 12 and 20v tho

[@sacredcowtipper1378]

@@bossmanz28 thanks. I am no longer in construction but have a bunch of Milwaukee M18 for that around the farm and my old dewalt nicad and nimh cordless. Yeah, i got the saw kit for that reason too to get the 15Ah battery as to buy the chainsaw and battery separate was around $800. Got it for $470 delivered tax and all through ACME. I bought 6 tools from acme but four boxes looked like they were opened and resealed and they were pretending these were brand new. I think that is illegal to not let the customer know you are getting open box. Anyhow i took pictures and contacted them already. I could have bought those four tools open box for much less on ebay. The chainsaw kit and edger attachment came in sealed boxes untampered. But the 600cfm blower, 15’ pole saw, pole saw attachment and brush cutter were not sealed right so I know they are open box. Most wouldnt complain but I sale surplus laser toners and fusers and if it is open box you get less than half of the retail price and if the boxes are damaged or have writing on them you might only get $100 for a brand new $400 laser cartridge. Very disappointed with Acme. I feel that was deceptive. Lets see if they make it right. Do you have the dcb118 or dcb1112 charger? 4 hour charging time is okay probably for me being i am not using it for business use and i do have the string trimmer kit coming in tomorrow from tool up so will have a 9Ah battery and another junky charger added to my outdoor equipment.

If you have cracked the code on the smaller, lighter, stronger, faster, and more long lasting, why then develop a battery that goes from a flexvolt brick to a cinder block?

15aH doesn't have high output cells though 🤷‍♂️

[@8bitsamurai6]

Damn sad how great the 840 really is even though the 850 seems fancier. I bet the new xr will be an 840 with modes. That would be a real show stopper cuz dewalt has the best chuck imo.

[@dustup2249]

You're definitely not a highschool math graduate if you don't understand that where the 15Ah battery excels is how many of those 1/2"x10" lag bolts can be driven on a single charge compared to your other examples. 15Ah batteries are marketed for an actual construction worksite advantage of needing less spare batteries, extension cords, generator outlets and chargers for each driver when you're packing the trailer in the morning and staying on task instead of the laborer finding a valid excuse to leave the task to get another battery and cup of coffee and Dunkin donut.

Why is barrel grip garbage? I feel singled out. 🙁

[@vincenzofoscolo8324]

Ciao posso farti una domanda ..io ho dewalt 796 p2 posso montare le batterie 18v xrflexvolt 54

[@PhillyFixed]

Ciao, se ho tradotto correttamente la tua domanda, sì, puoi utilizzare batterie Flexvolt da 54 V su strumenti Dewalt da 18 V, incluso il 796.

Fuck it, I'm putting a Tesla power wall on my impact driver

[@PhillyFixed]

🤣

[@waltkingfrancisco1342]

How many cuts on a flex voltage 12" miter saw using 2×15 volt batteries.

[@PhillyFixed]

Not sure, I don't have that saw available to me unfortunately.

[@horvathbotond2717]

DID YOU JUST TOUCHED A DEWALT WITH THOSE GLOVES???🤣🤣🤣 jk

[@PhillyFixed]

Heresy!

[@msk3905]

I always voltage makes/dictates the power with amperage just increasing run time?

[@PhillyFixed]

The amp-hours rating is a measure of overall battery capacity and runtime. However, larger capacity batteries tend to have 2 or 3 rows of cells in parallel, and that increases the pack's maximum current output. So indirectly, larger Ah batteries tend to have higher output. In this vid, though, all of the extra 18650 cells still couldn't surpass a single row of 21700 cells in the 4ah pack. Voltage can make a difference, but in practice I've not seen where 24V tools (Flex, Kobalt) have much of an advantage over 18V/20VMax tools just by virtue of the voltage.

[@bird718]

15Ah is the way to go with all tools from now on

[@PhillyFixed]

You'll end up with killer biceps!

[@mikefarkas1463]

How much heavier is that 15h?

[@rudyfromsomewhere3066]

X3 weight of 5ah battery, 30cells are against ten cells in 5ah

[@PhillyFixed]

The 15ah weighs 4-1/2 lbs, the Powerstack weighs around 11 ounces. Huge difference!

[@florinelr8154]

Hello, Does the power stack last as long as the 18V and 5Ah one?thank you

[@PhillyFixed]

The Powerstack is 1.7aH so it won't last as long as a 5aH. Not sure what you mean by 18v -- outside the United States, DeWalt's tools and batteries are labeled "18V" rather than "20V Max" but they are the same. Is that what you mean?

[@johngaskey218]

Interesting…I’ve been seeing comparisons between the 5 and the stack with the stack being almost the same, looks like some sandbagging going on

[@PhillyFixed]

Don't forget the slim 4aH has high-output 21700 battery cells while the 5aH has standard output 18650 cells. Thanks for watching!

[@jamesmocharski4803]

5:50; While DeWalt appears to be making huge strides in battery technology…I guess the same can not be said for solutions to keep your hands warm in a cold Pilly garage? Dare I say it? Been caught…..Red Handed? (Yeah….I said it.)
