AnonymousJoe Posted October 29, 2016 Report Share Posted October 29, 2016 I've been using my dewalt tools more lately now that my Milwaukee drill is out for service. I could use some new batteries tho as all I have is the old 3.0, so anyone know when the 6 is supposed to come out? Quote Link to comment Share on other sites More sharing options...

KnarlyCarl Posted October 30, 2016 Report Share Posted October 30, 2016 Don't count on a 20v xr 6ah pack, that's probably what they made the flexvolt for, so they don't have to make two of the same capacity.....might as well get the 5ah if you are looking to keep the size down Quote Link to comment Share on other sites More sharing options...
AnonymousJoe Posted October 30, 2016 Author Report Share Posted October 30, 2016 Sure but I was reading on toolguyd he had an article on the dewalt media event and he even showed a picture of the 20v xr 6.0 battery that is supposed to be released 1 Quote Link to comment Share on other sites More sharing options...

jeffmcmillan Posted October 30, 2016 Report Share Posted October 30, 2016 First off, it's going to be a bit bigger and heavier, not flexvolt big but a little, hopefully to avoid the problems Bosch had. Also the 6ah batteries tend to have a significant premium over the other batteries because of the expensive cells they use. It's almost 100% increase in price for up to a 20% increase in runtime. That's not worth it in my book. I'm happy to seem them push the 5ah prices down though. 1 Quote Link to comment Share on other sites More sharing options...

AnonymousJoe Posted October 30, 2016 Author Report Share Posted October 30, 2016 Since u guys brought up flexvolt I have another question. I read somewhere about a tool having a noticeable power increase going from a compact battery to a higher capacity 10 cell battery. Now would u see a noticeable power increase using a flexvolt battery because it has 15 cells vs a 4 or 5 ah battery with 10 cells? Quote Link to comment Share on other sites More sharing options...
Bremon Posted October 30, 2016 Report Share Posted October 30, 2016 20v Max 6.0 is out in November. 3.0/9.0 FlexVolt is out in either November or January: there's conflicting info out there. Quote Link to comment Share on other sites More sharing options...

The 20v Max, like Metabo Li-HD and Bosch eneracer will use 20700s to compensate. M18 6.0 is 18650. Quote Link to comment Share on other sites More sharing options...

That depends on if the tools is capable of using the extra power, and before you ask I have no idea which ones. It will also take longer to overheat in heavy use for any tool.

Now would u see a noticeable power increase using a flexvolt battery because it has 15 cells vs a 4 or 5 ah battery with 10 cells? The higher capacity batteries certainly are able to provide more current due to the extra cell. That should also hold for 15 cell compared to 10 cell batteries. HOWEVER, not all tools are manufactured to take advantage of the extra current. Drills usually aren't, impact drivers usually are (for instance).

The 6.0 is bigger than the 5.0 for a reason. 20700 are the future. Everyone will get there eventually, whether willingly or kicking and screaming 1 Quote Link to comment Share on other sites More sharing options...
AnonymousJoe Posted October 30, 2016 Author Report Share Posted October 30, 2016 Lots of info here thanks. With all that said I'm suprised Milwaukee would use the 18650 in their 6.0 , ithought their battery tech was supposed to be top of the line. I started out with dewalt tools and a year ago I switched to Milwaukee. The one thing I've noticed is that when using my Milwaukee drill I can tell u the exact moment the battery is halfway run down because u notice the power/performance drop. Theres a lot more to batteries than I thought and I'm just starting to get into it and read about it so thanks for the info. Quote Link to comment Share on other sites More sharing options...

What problems did Bosch have with their 6.0 Ah battery? Quote Link to comment Share on other sites More sharing options...
PH1 Posted October 30, 2016 Report Share Posted October 30, 2016 Bosch 6.0 Ah batteries use regular 18650 cells, while their 6.3 Ah EneRacer battery switches to 20700 cells, like Metabo LiHD [max. 6.2 Ah] batteries, the newest cordless power tool batteries from Panasonic themselves and the upcoming 6 Ah XR and 9Ah FlexVolt batteries from DeWALT. Pictures of Metabo LiHD, the new DeWalt XR 6-0 Ah + FlexVolt 9-0 Ah and Bosch EneRacer GBA 18V 6.3 Ah battery packs which all use 20700 cells instead of the usual 18650 cells. Dimensions: 18650 cells: diameter 18 mm; length 65 mm. 20700 cells: diameter 20 mm; length 70 mm. Picture sources: Pic 1-6: https://www.bosch-professional.com/de/de/community/category/eneracer-die-neue-akkutechnologie/10603405-t Pic 7-9: http://www.sg-toolbox.com/bosch-eneracer/ Pic 10-11: http://toolguyd.com/dewalt-2016-media-event-5-hot-tools/ Pic 12-13 http://www.coptool.com/cordless-power-tool-lihd-battery-cells-18650-vs-20700/ DeWALT FlexVolt 9.0 Ah battery with 20700 cells. FlexVolt 6.0 Ah only use 18650 cells according to Coptool. DeWALT XR 6.0 Ah battery with 20700 cells Tesla will switch from 18650 cells to 21700 cells for the upcoming Model 3, previously they said 20700, but they have changed it to 21700 or 2170 as they call it.

jeffmcmillan Posted October 30, 2016 Report Share Posted October 30, 2016 I think part of the differences is tesla moving to 20700 so in addition to the 30% volume increase the cells themselves have a higher performance. The Bosch 6.0 batteries would often have a shorter runtime than 5.0 because at high draw the battery wasted more energy and heated up.

Craigh9916 Posted October 30, 2016 Report Share Posted October 30, 2016 The new 6.3ah bosch battery has just been released in the UK but stores haven't got them in stock yet so as soon as I see one online in buying it !

However the datasheet for Panasonic NCR20700A hasn't listed any specifications above 30 A discharge rate: http://akkuplus.de/mediafiles/Datenblatt/Panasonic/Panasonic_NCR20700A.pdf Quote Link to comment Share on other sites More sharing options...
