Jronman Posted September 16, 2016 Report Share Posted September 16, 2016 If the Flexvolt was 60v at 9.0 amp hours instead of 2.0 in a package the size of the current flexvolt, would it be gameover for high demand m18 tools until an m54 comes out?

Might as well put it on a back pack it would be so big because I don't see that happening with the tech available at this time Quote Link to comment Share on other sites More sharing options...

I suppose a super fast charger would need to be designed so it don't take all day to charge or just design a battery that uses more advanced technology than lithium ion.

The charge time is just one problem. The size required for a 9 AH 60v pack would be roughly 5x the size of the current battery. Next try to imagine how to get the heat out of all those cells under load. I'm pretty sure that sort of power is going to require a significant advance in density before it sees the light of day.

Bremon Posted September 17, 2016 Report Share Posted September 17, 2016 Realistically the M18 HD9.0 and the FlexVolt 3.0/9.0 are using same principle: more cells = more current draw = more work/power. They are wired differently but the watt hours are the same. The Dewalt pack is even bigger physically to achieve higher discharge rates. Thank god for rapid chargers.

Well in terms of stored energy one would have 162 watt hours while the other has 486 watt hours. It's a hypothetical that is analogous to saying what if GM could put out a V8 Silverado with 1095 horsepower and 1260 lb/ft of torque at the same runtime, or same specs w triple the fuel economy; would F150 ecoboost be in trouble? Yes. Undoubtedly, but in both cases it's physically impossible to achieve that while keeping the same form factor. 1 Quote Link to comment Share on other sites More sharing options...

I thought higher voltages heat up less quickly than lower voltages and a reason being they are more efficient? Quote Link to comment Share on other sites More sharing options...

In the motor that can be the case depending on how it's designed. In the battery each cell has the same load regardless of the total high current or high voltage configuration. 2 Quote Link to comment Share on other sites More sharing options...

I am hanging on and waiting to see if dewalt bring one out! That is the only reason I have not bought the 60v one!! There has got to be more things to come on the 120 v side of the flexvolt system. It would be odd to only have the 12" miter saw. 1 Quote Link to comment Share on other sites More sharing options...

If I was to guess I would think they were worried about price points on the new system, and overwhelming people with the need for a monstrous amount of batteries off the hop. I don't really know though. The hybrid option adds a decent chunk to the cost from my understanding; maybe easier to sink that cost into an expensive mitre to start with. Just guesswork on my part of course. 1 Quote Link to comment Share on other sites More sharing options...

Just guesswork on my part of course. DCS778 also in Germany larger cutting capacity max. cutting specs 90/90 deg = 305x85 mm (270x60mm in comparision to DCS777) 90/45 deg = 305x58 mm 45/90 deg = 215x85 mm 45/45 = 215x 30 mm sawblade is 250x 30 17,2 kg compared to 14kg of DCS777 cheers mike 1 Quote Link to comment Share on other sites More sharing options...

Just guesswork on my part of course. I think that might be the case but the cordless miter with just an adapter and no batteries is only $50 more than their normal top of the line miter saw. Definitely worth it for a cordless option down the line. Quote Link to comment Share on other sites More sharing options...

Grumpy MSG Posted September 20, 2016 Report Share Posted September 20, 2016 And if you look for just the AC adapter, the price is..... $49 http://www.homedepot.com/p/DEWALT-FLEXVOLT-120-Volt-AC-Adapter-DCA120/207164710 Quote Link to comment Share on other sites More sharing options...
Bremon Posted September 20, 2016 Report Share Posted September 20, 2016 The adapter isn't much more than a grounded cord that covers the mains from my understanding. The actual conversion is done in the machine and is probably more expensive than that. 1 Quote Link to comment Share on other sites More sharing options...

It's actually less complicated than it looks ... only two components and under $10 for good ones at low quantity. Don't even need a transformer since the battery is the same voltage as mains. 1 Quote Link to comment Share on other sites More sharing options...
HiltiWpg Posted September 20, 2016 Report Share Posted September 20, 2016 Don't forget the filter Capacitors to smooth out the ripple. Nothing worse than pulsating DC.
