Does any one know how many amps you can go up in the same size 60v 2ah pack ?  Like in 20v max the 3ah,4ah,5ah are all the same size battery ….

When you use the 2500 mAh and 3000 mAh 18650 cells your current draw is limited compared to the 2000 mAh. I would think they could do a 2.5/7.5 but cost might be prohibitive compared to jumping to a 3.0/9.0. It would be the FlexVolt equivalent of an XR5.0 whereas the current lowend FlexVolt is equivalent to a 4.0 with an extra row of cells. 

Thanks Bremon..so they could do a 60v /7.5 at the same size as the 60v 2.0 but more cost affordable to go to 3.0/9.0 …..really hoping batteries don’t keep getting bigger then the 60v 3.0/9.0..just to big ….but if that’s the max size ok…like 12ah 20v max or 4ah60v ….

They could do 3.0/9.0 at the size of current 2.0/6.0 but could run into overheating packs and disappointing runtimes because of poorer discharge rates. Doesn’t seem to affect Milwaukee 9.0 which is using 18650 but I think we will see Dewalt has more ambitious plans for FlexVolt than Milwaukee might for their 9.0. 

I think 20700 cells for power tools are in their infancy so I would expect 12+ ah packs at the 3.0/9.0 size rather than getting bigger. 18650 are pretty much maxed out I think. 

To quote my self from another forum:

“as I understand it the discharge rate of 18650 cells above 2.5ah are not very adequate for the high demand put on them by most tools where as 20700 cells have larger headroom to go beyond 3ah. I suspect Milwaukee’s 9ah (using 15 3ah 18650 cells) can overcomes this problem due to the vast stable of brushless tools that require somewhat less dischage of the battery. Dewalt on the other hand has mostly brushed motors out in the hands of their users and wouldn’t want to gamble on potentially exploding batteries.”

I would suspect Milwaukee overcomes the current draw issue by having a weaker grinder, mitre saw, Super Hawg, etc. From what I’ve been told Dewalt has some ridiculous aspirations for FlexVolt and the 20700 is as much about future-proofing as it is about supporting current tools. Last years #worldsfirst stuff was just the beginning from what I’ve been told. 

Thanks Bremon… 12ah at the 3.0/9.0 size would be awesome…so that would be 20v max 12ah and 60v at 4ah…i  think……I think if they get up to 60v at 6ah that would be more then enough for all day work on any tool

6 is quite a stretch, 5 as of yet is doubtful but 4/12 is a very likely…. Give it a year or two and who knows lol

4.0/5.0 I could see happening. 3.0/6.0 seems crazy compared to the  1.3 and 3.0 of years back. 

Haven’t seen this mentioned but if anyone cares, the size of the cell is actually the part number…

18650 is 18mm diameter x 65mm length

20700 is 20mm x 70mm

18650 cells are truly at their limit at 3000mah. The heat generated at high amp discharge just burns them up and shortens the life.

20700 cells have lots of headroom at 3000mah, and are on par to hit close to 5000mah at the ceiling before its all done.

However, with the efficiency of the tools going up so quickly, I don’t necessarily think there will be a strong need for batteries above 6ah sizes. Yeah, it can be done, but the tool becomes so heavy and unweilding at that point, I don’t want to have to carry and use the darn thing. Just give me a few 4ah or 5ah batteries, and a better, quicker charger (maybe a dual input voltage of 12/120 volts with a 30 minute charge time for 5ah batteries).. Or contact charging like bosch or even maybe a tough system charger powered by a massive battery pack enough to charge say 5 or 6 5ah batteries

With a setup like that, I’d run circles around anyone with a 9ah setup.

It’s actually 65mm and 70mm but otherwise great points. ToughSystem power bank sounds cool but they’d likely rather sell you the 4 bay inverter.

That would really depend on the tool being used, for example Milwaukee 2715 fuel rotary hammer drill. Drilling a 25mm dia hole paired will 9ah battery will run circles around the same drill with 5ah battery. 9ah gives the drill more power, drilling time is quicker and the 5ah battery overheats pretty quickly 

It’s interesting ….I agree battery weight is going to come into play…I think Dewalt will go up to 60v / 4ah ,and 20v max 8ah…I mean that’s enough for all day….then I hope Milwaukee and Dewalt can get different cells for more compact batteries …like a slim 5ah..and 20 min charge times…..I’m excited about this years new tools coming out….

It’s here the 20v 9ah / 60v 3ah….it’s BIG…..Does anyone know what the 2 round holes are on top of the new 9ah ? (Heat disperse?)……batteries in order…………………..9ah,6ah (Flexvolt) 6ah (20v max) 5ah,2ah..

Really….that would suck ,because it is definitely being used outside in the rain and snow….I haven’t read any info on it anywhere and acme didn’t know….

Maybe it’s there to wire into your car battery to jump start it ?

Nah you just use the B+ and B- terminals ?

That’s an expensive drop of water if it voids the warranty , lol ? Scary thought…

That’s not a battery that is a friggin power plant. Holy crud that thing is big!

Have you ever had a battery crap the bed on you? I haven’t. When they’re available around me I’ll be the guinea pig if you guys like. The interior of these batteries are generally sprayed and potted, the M18 batteries have drainage holes on the bottom. 

 No,,,never had a battery fail on me….and that’s using them in pouring rain and snow…high temps around 100 and lows of -10.,,. …I did put water in the hole and let it sit a minute..no change…

 That battery is a beast. 

Got a quarter?

Thanks for sharing that, great to know!

ToughSystem radio is no surprise; it won’t fit a FlexVolt 2.0/6.0 or a 20v XR 6.0 either lol. 

I wonder if the new flex volt will work on 20v blower

It work s pretty slick on hedge trimmer but alas I don’t have the blower. @SevenOddosFence was selling his yard equipment and I should’ve jumped on it 🙁

Hi,,thanks for the videos guys…..the new 9ah will fit in the blower ,very tight and it sticks out the bottom ,so your battery rests on the ground  not the cage..

Cool man Thank you??I love that blower! How’s the runtime with that bad boy on there? 

Double the run time…really don’t notice the weight,,but b careful setting it down

My caged lightning has arrived! Came via horseback from Acme but it arrived. [External image (uploads.tapatalk-cdn.com), not copied]

This is really testing my patience. With regards to product release you Americans really are fortunate to be such a large market lol. Once your market gets a bit saturated manufacturers remember there are another 10% more people to sell to up north!

hey,”bremon” sorry I don’t know how to..drag,or copy or paste your name…I’m only a framer,no computer skills……..in Canada,( btw my gramps lived in Nova Scotia)  they have a Dewalt 1400 jump starter,compressor thing …you got it ? Heard of it ? It’s only in Texas here…

Whoa whoa whoa….there is something north of the USA?!?!?!!?!

I though it was just woods and wood boogers?

whoda thunk?

I wonder if Trump knows this?!?!?!?! We better build a friggin wall!!!!!!!

Also-ran Scott Walker wanted a wall between us as well as your guys and Mexico. The Big League pumpkin says that’s tough though lol. 

@Framer joe did you visit Montreal by chance?

 Bremon….hell ya..

I spent two weeks in Montreal back in 2000 when I had LASIK. I mean this truthfully, San Diego and Montreal are the two cleanest and nicest cities I’ve ever visited. Both places had more friendly people I’ve ever run into that I’ve never met. So hooray for Canada. Now….having grown up in Coastal Maine, WTF with Quebec?!?!?!?!?!?!?

Whoa I musta missed the clean and nice parts…. been there 4 times and stayed at a “resort” in Mission Valley… it was ok but I’ve definitely been to better.

Yeah my Dad was posted down there with the shipyard working on a rescue submersible for months so I visited for a couple of weeks. I stayed downtown, went to Corona, the zoo, the highways were all Ivey covered and a bum asked me for money. When I said I didn’t have any he said…and I quote….this is important because I’m a New Englander and visit Boston quite often….”hey no problem dude, have a nice day”.

The reason I prefaced that is because if I was in Boston, I would’ve gotten rolled, stabbed mugged and lets face it….raped…by homeless people. Absolutely lovely town!

HAHAHA right, Was in Boston for a few days and stayed at the Sheridan, I had an awesome room there, however some buddies had a 2 bed closet that smelt of dead hookers.  Had to walk about 2 miles to a beer store and the only micro brews they had were from my home town…. fortunately I didn’t have to interact with the locals much at all but WOW traffic is crazy there.

Yeah dude. Boston is a bitch to get around in. Figures though, they still have a few original cobblestone roads in bean town. Sam Adams is there though so that’s good!

Funny enough Quebec is widely regarded outside of Quebec as stereotypically being the rudest, most blunt Canadians lol. Montreal is more diverse and tolerant of anglophone though.

Born and raised in Quebec city. I know people outside of Quebec think that Montreal is more tolerant of anglophone but trust me on that, you’ll find more “hard line” separatists in Montreal then elsewhere in the province. People outside of Montreal just don’t feel threatened by English.
