Vince I am a former Motorola engineer and worked a lot with batteries on our phones. That flex circuit on the batteries has all the brains that controls the charging of the batteries, and most of the circuitry is safety circuits with thermistors that measure temperature and prevent batteries from overcharging and exploding, the control the charge rate from rapid to trickle, and they also have communications in them that talk tot he tools to read the tool and determine if it wants to be a 20V battery or a 60 volt battery. Sometimes batteries have sensors that determine you are hooked up to an unapproved charger, and they will not allow rapid charging, only trickle charging. there's a lot of tasks on their plate for these circuits.
FYI 650 mm is 65 cm= 25.6", should be 65 mm long = 2,56". 20700 is only 70 mm long= 2.76". Quite a difference I think. The diameters you gave are correct.
See every time they add another row of batteries for the 4ah, 6ah, 8ah etc they wire them in parallel which lowers the resistance (impedance) which is why your tool can pull more amps and feels more powerful when using a larger battery.
Correct me if I am wrong but, I believe Flexvolt batteries have been using 20700 cells. With flexvolt advantage on the seen, I think some newer iterations of flexvolt batteries are now using 21700 cells.
Hello I need your help, I bought a 4A 20V Deolt battery It has a qrcod on it when scanning it, it took me to the Deault website, but it gave me that the product is not available Does this mean that the product is original to me or what
Do you have a video showing how to put back together? I took the screws out but something was holding the cover on and I didn't want to just yank it apart. Trying to find out if these 5ah batteries that I bought on amz are fake or not. According to dewalt's support site they are but then so are the ones displayed on home depot's website, according to dewalt's guide to spotting fakes.
I believe the 9 flex is 20 700. Dewalt could not wait for 21700 production. Benefits was minimal. But main reason was to get 60v launch out faster. I would guess the 12 flex and soon 15 are in same size casing and offset in the rows.
You’re correct, both of those are PCB’s that likely contain the logic and any balancing wires to make sure no cell overcharges etc, and I love how Metabo does their 36V “flexvolt” style. When used at 18v you have double the Ah rating you expect, instead of the 60V Ah seeming weak. But Dewalt did do this years ago so credit for trying something different.
When you put cells in parallel the voltage stays the same (example: 3 cells with 3V each put in parallel you still have that 3 volts, in series you add the voltage up)
Can someone answer: do dewalt battery packs include over discharge/undervoltage protection? I've heard in some places that it's in the tool. If I use a battery adapter, I've heard I could over discharge the battery. Is that true?
I’ve taken the 6ah flex pack apart No FETs to disconnect the battery for over discharge. Cells are always connected . The drill does the switch off for low voltage. As for charging as long as you don’t go over 4.2v/cell (4.1v/cell is safer) you should be ok.
@@pfb3264today i was using my dewalt grinder with a 5ah battery and it streight up died. Went to recharge it and it isnt charging. It got completrly drained. Clearly the undercharge protection didnt work here.
Three 18650s in parallel will provide more current than two 21700s in parallel. So, yes, the flex-volt in 20 volt mode puts out more current. Under continuous beating, the tools will smoke sooner on the flex-volt.
Not inherently true. It all hinges on what the specs of the cells are. Two 21700 Molicel P42A's in parallel would smoke ANY three 18650's in parallel for example.
Hello Vince, As you are the only channel i know who responds to comments, I have an important question: Can you do an impact wrench vs impact driver comparison with tests. hikoki vs milwaukee vs dewalt vs makita? How does the wrench keep up when doing driver tasks and vise versa.
Clearly, the 60v battery is running in 20v "mode" on a 20v tool. Don't think anyone was arguing against that fact. There are two factors that are not addressed by either you or Subaru. Voltage sag and amp draw. Both major factors in addressing the stated hypothesis. Logic would say that the voltage sag on the Flexvolt would be less than the standard (single or double series) 20v batteries. Flexvolt MAY also be able to supply more amps to the tool (bc of its triple series configuration). If either one of these statements is true, then the total wattage to the tool would be greater (potentially much greater) than a standard single or double series 20v battery.
did a science experiment this week. did some yard work with a dewalt 20v blower and a dewalt 20v weedwhacker. tried both a 5ah 20v and a 6ah flexvolt. the blower was about the same. but the weedwhacker acted like it was steroids with the flex volt on it. why? who knows unless the weedwhacker could somehow draw more current out of the flex volt.
@@boburz7976 yeah I knew what you meant, but if you watch his channel the impact wrenches he is testing are all 20v. A lot of the reasons why are because the Flexvolt batteries have 21700 cells which generally have a higher discharge rating then the 18650s which means that if your 20v weedwhacker requires say 50 amps of discharge current to run optimally, the 18650 cells physically may not be able to discharge fast enough to supply that much current even though it's getting 20 volts it might only be getting 20 to 30 amps, but if you throw on the bigger Flexvolt batteries with the 21700 cells with a higher discharge current it can supply that 50amps @ 20v no problem. If you think of current in terms of a water hose and it might make a little more sense. If you have a large water hose, then your going to be able to fill that 5 gal bucket a lot faster than if you are using an ice maker line that's 1/4" thick, even though you have the same water pressure (volts) all throughout your house.
They both just so heavy. Great for saws and such. I have a flex volt circ saw that I love. But putting that flex volt on my impact feels terrible lol. So the 5ah and lower battery have their place. I personally love 4ah and 5ah on my drills and impacts. That said, those 9ah flex volt batteries last forever on the circular saw.
Yea I have some of those too but they run down so fast. They are nice and light though. For what I do, the 4-5 ah range is about the perfect balance of long lasting and weight The 5 ah battery is the best power to weight ratio battery that dewalt makes though imo. By power I mean long lasting
Thanks Vince. I love my XR 6 amp hour batteries I have four of them right now I am not into the flexvolt tools just want to wait to buy those to another generation comes out love your videos bleeding yellow and Detroit
@@loucifer323 I see your confusion. Sometime in 2018 Dewalt switched from Sanyo 20700A cells to the better and cheaper Samsung 21700 30T cells in their XR6.0
I think the price of all Dewalt batterys will probably go up .There already to high for my budget. I guess I missed the boat on the economy as always a day late and a dollar short.
I bought one 6.0aph flexvolt battery and that thing didn't last for shit, it still works but has a bad cell or two and that happened after several charges, they suck.
don’t understand how 10 cells (in configuration 2x5) and 18 cells (3x6) can be compatible because the voltage of lithium cells still the same at 3.7v nominal.. the non flex 3.7v x 5 = 18.5v (5s2p construction) and the flex 3.7v x 6 = 22.2v (all in series the flex give 3.7v x 18 = 66.6v in 6s3p/18s1p construction).. 5s2p mean 5 cells in series by 2 in parallels (=10).. i suspect the non flex to be a recap of the old 18v dewalt packs and less powerful on 20v tools because the voltage is 3.7v lower.. that mean some sense to you?? (for to be matched in voltage, the 18650 pack should be 15 cells instead of 18 or the 20700 pack should have 12 cells)
They could make the FlexVolt batteries smaller and cheaper if they didn’t make them compatible with 20v. That would make them more affordable and slowly phase out 20v Max XR tools to Atomic and the now XR tools to FlexVolt🤔
Vince , I do like you say 20V MAX because that is exactly what it means: max voltage with no load. during load it drops to 18V. In advertising, 20V sounds more powerful than 18V. Just check the voltage on an 18V vs a 20V fully charged batteries. Not much difference there.
It's not about the load. The batteries are 4.2V when fully charged, and 3.6-3.7. nominal, depending on who you talk to. So if you have a 2p5s configuration, like the 20V max battery does, at 5*3V6=18V. 18V is what most manufacturers say. 5*4V2= 21V, so they're using 4V as a nominal for each cell.
Nope, they are very comparable as far as which is "much powerful." The 20/21700 batteries just have a bit more headspace as far as capacity goes. A bigger battery doesn't necessarily mean the CDR is higher.
I still think the XR has 21700 cells and that you just swapped them out before the video or during a cut. ;) Just kidding. Very interesting video, though!
18650 is 18mm x 65mm 21700 is 21mm x 70mm I dont know what the 0 at the end is for. Maybe just to sound good? Haha but you could use your fancy measuring calipers you use for tools to confirm size.
Vince, as I love taking things apart....I’m not doing that to my tools & batteries, I’m crazy, but not that crazy. That’s what we have you for & why your the best👍🏻 b/c you take the “risk” for us all💪🏼 Cheers✌🏼
For what it’s worth, the size/dimensions are in the name, and no I’m not inherently smarter than the next guy either I just nerded out on the details a while back. 18650’s are 18 inches by 65 inches....wait....make that millimeters :P 21700’s are 21mmx70mm. Thank god for Elon musk or we’d probably still have NiCad tools. It’s also interesting to see that Dewalt Cheaped out compared to Bosch and didn’t put the 21700’s in little air conditioned condos for each cell.
Andrew Delashaw his tesla demand for the batteries escalated worldwide production then other major competition car manufacturers also sent demand, then elons home battery systems just about crashed the entire battery manufacturing system, these changes alone by elons companies spurred rapid developments in the delivery systems, and optimal motor efficiency which benefited all of us as the technology has now moved on to other power delivery systems leaving a glut of supply, these developments translated into tools.
Ummmm... thank Milwaukee? They own the battery patents on 18v Li-ion battery packs for tools and drove that innovation. Elon Musk has nothing to do with Li-ion in tools.
Well i can say i am wrong, my understanding is milwaukee says they were the first and hold the patent to exclusive rights up to 20amps and then amended the suit to include every tool that utilizes any li-ion battery ...but isnt that like saying whom ever added sugar to chocolate holds the rights to all chocolate bars? Elon and his push and open technology gave tons of manufacturers a leg up on RD costs, if he hadn’t done that then most tool manufacturers wouldn’t have even made the foray into the production, thats my opinion, and Milwaukee got the short end of it because they could have controlled the battery market to an extent. Did milwaukee ever win their suit? Or did they just take a royalty? And i do appreciate milwaukee giving their 5ah batteries away like candy (chocolate bars).
Yo Vince @VCG Construction! Thanks for the video cuz! Looks like they are running 18650s in the flexvolt. And 20700 in the 6ah 20v max. They run the same 20700 in the 3ah slim 20v max packs. Only it's a 1p pack instead of a 2p. From what I understand, they do run the 20700's in the 9ah flexvolts. Not sure if the 12 runs 20700 or 21700 Not quite a m18 HO pack with those sweet MANgenta colored Samsung 21700 cells (on the 8 and 12 only.) I am sure you've had one apart, and it's a beautiful pack! Huge difference between the battery packs. No smart anything going on with the 20v max pack. Flexvolt seems to be a switching pcb. And probably the closest in terms of wizardry to the Redlithium packs but not equivalent by any means. Milwaukee's wizardry looks like it belongs on a rocket ship. Or in a crazy gamers computer. It's unbelievable. Glad you had these quick little shenanigans. 👍 You're a beast! 💪
I stand corrected. With closer look, those are 21700 cells! I wonder when they changed them. Check the date on the battery if you will Vince. My 2018 3ah are running the 20700's and so were the 6ah xr packs. Maybe dewalt switched them at a certain point of time? Try to find an older dated 6ah XR pack. Say early 2018 or earlier? And compare it to the new one you seem to have. Probably a late 2018 build date at least or newer. I have heard rumors that dewalt switch to 21700 cells in the flexvolt 9ah and the 12ah flexvolt was running the same 2170040t cells that the m18 12.0 is. We need more research! My 3ah slim is running some bright red Sanyo 20700s is all I know. And at the time I was informed they shared the same cell as the 6ah 20v max. Pretty cool. Dewalt should probably push that like milwaukee does. Even though the battery guts on the batteries are far different. Anyway, I stand corrected. As I said, I know they were running 20700's. I would like to know what all batteries were switched and when. Thanks again broseph! 👍

Saved me ten minutes, cheers
The 6ah Flexvolts uses 18650s, IIRC the 9ah and 12ah Flexvolts use Panasonic NCR21700A/B Cells.
The battery names denote the size. An 18650 is 18 mm in diameter do 650 mm long. A 20700 is 20 mm is diameter and 700 mm long.

For what it’s worth, the size/dimensions are in the name, and no I’m not inherently smarter than the next guy either I just nerded out on the details a while back. 18650’s are 18 inches by 65 inches....wait....make that millimeters :P 21700’s are 21mmx70mm. Thank god for Elon musk or we’d probably still have NiCad tools. It’s also interesting to see that Dewalt Cheaped out compared to Bosch and didn’t put the 21700’s in little air conditioned condos for each cell.
Wth does Elon musk have to do with Li-ion? Or Li-ion batteries in tools. LOL.
Andrew Delashaw his tesla demand for the batteries escalated worldwide production then other major competition car manufacturers also sent demand, then elons home battery systems just about crashed the entire battery manufacturing system, these changes alone by elons companies spurred rapid developments in the delivery systems, and optimal motor efficiency which benefited all of us as the technology has now moved on to other power delivery systems leaving a glut of supply, these developments translated into tools.
Ummmm... thank Milwaukee? They own the battery patents on 18v Li-ion battery packs for tools and drove that innovation.
Elon Musk has nothing to do with Li-ion in tools.
Andrew Delashaw 100% correct Andrew, nothing to do with it
Well i can say i am wrong, my understanding is milwaukee says they were the first and hold the patent to exclusive rights up to 20amps and then amended the suit to include every tool that utilizes any li-ion battery ...but isnt that like saying whom ever added sugar to chocolate holds the rights to all chocolate bars? Elon and his push and open technology gave tons of manufacturers a leg up on RD costs, if he hadn’t done that then most tool manufacturers wouldn’t have even made the foray into the production, thats my opinion, and Milwaukee got the short end of it because they could have controlled the battery market to an extent. Did milwaukee ever win their suit? Or did they just take a royalty? And i do appreciate milwaukee giving their 5ah batteries away like candy (chocolate bars).
Boooooooriiiiiiiinnnngggg
Yo Vince @VCG Construction! Thanks for the video cuz! Looks like they are running 18650s in the flexvolt. And 20700 in the 6ah 20v max.
They run the same 20700 in the 3ah slim 20v max packs. Only it's a 1p pack instead of a 2p.
From what I understand, they do run the 20700's in the 9ah flexvolts. Not sure if the 12 runs 20700 or 21700
Not quite a m18 HO pack with those sweet MANgenta colored Samsung 21700 cells (on the 8 and 12 only.) I am sure you've had one apart, and it's a beautiful pack! Huge difference between the battery packs. No smart anything going on with the 20v max pack. Flexvolt seems to be a switching pcb. And probably the closest in terms of wizardry to the Redlithium packs but not equivalent by any means. Milwaukee's wizardry looks like it belongs on a rocket ship. Or in a crazy gamers computer. It's unbelievable.
Glad you had these quick little shenanigans. 👍
You're a beast! 💪
I stand corrected. With closer look, those are 21700 cells! I wonder when they changed them. Check the date on the battery if you will Vince. My 2018 3ah are running the 20700's and so were the 6ah xr packs. Maybe dewalt switched them at a certain point of time?
Try to find an older dated 6ah XR pack. Say early 2018 or earlier? And compare it to the new one you seem to have. Probably a late 2018 build date at least or newer. I have heard rumors that dewalt switch to 21700 cells in the flexvolt 9ah and the 12ah flexvolt was running the same 2170040t cells that the m18 12.0 is. We need more research!
My 3ah slim is running some bright red Sanyo 20700s is all I know. And at the time I was informed they shared the same cell as the 6ah 20v max.
Pretty cool. Dewalt should probably push that like milwaukee does. Even though the battery guts on the batteries are far different.
Anyway, I stand corrected. As I said, I know they were running 20700's. I would like to know what all batteries were switched and when.
Thanks again broseph! 👍
