That's simply not true. Lithium is lithium, packing more of it into a cell doesn't make it perform any better or worse. It's longevity would be better compared to a smaller celled battery but that's not to say it would perform any better based on what's there. More cells offer better longevity at lower voltage.
Don't really think you are correct ?
The 21700 cells have a higher continuous amp output then 18650 cells. That's what's toolsbane is saying.

If they make em Bosch sized that it wouldn't be much heavier to now and help Alot

Doesn't a propane heater take the oxygen away from the room you're using it in ?

Keep us posted !

Because in saw way every power tool company is always playing catch-up to others in some categories.
You can't expect every power tool company to bring out anything and everything all other companies have brought out
A little patience goes a long way.

There is a cordless polisher coming but it'll look nothing like that
Take the po5000 and add a battery at the back

deWalt concrete saw is out in Belgium

Thanks for the update jim

Bosch sized batteries will fit. No problem

A flood would have already fixed itself in this type. Cheap trimmer tend to have a plastic ' Carter' at the bottom. Possible a small crack ? Drawing air?

Seems like youll have to redo your testing with the flexvolt grinder
and while you're at it.... The deWalt and Bosch grinders with normal 6 amp batteries 😛 hahahha

Hi korno.
If it's pure guesswork, I reckon the flexvolt would probably be around 27-30 for power by comparison.
No idea on runtime. It may win because the test would be far easier for it and hence not heat up the cells too much....
Aha!
That alot of power difference.
Unless their was a thermal shutdown on a battery do we think that a hotter running battery looses runtime ?

Somewhere in the future:
WUT02. A Bluetooth adapter you can plug into the socket of your existing corded vac.
To enable AWS tools with existing vacs

Btw. There's an AWS adapter coming that you can plug into the socket of any corded vac u already own
so you can start all AWS tools with your existing vac ( if it has a socket of course )

@dwain Dwain if you'd had to take a guess and you would do these tests on the flexvolt grinder. What You'd think the results would be ? ( Like guessing hypothetically 😛 )
id assume you'd score the power more like 25 ? ( Compared to 20 for the 18v deWalt grinder for example ).
how would the runtime go ? Logically I'd think the flexvolt grinder would have less runtime then their 18v grinder you tested right ?

Nice job guys

Nothing yet so far

Or perhaps even brushes if it's some years old ?

Bosch did it right 😃

I'm confused, are you saying I'm not entitled to an opinion because you don't agree with it?
The sales man @kornomaniacsells tools all day long; he'll have a clearer picture of what they're selling and to whom, I unfortunately have to make my money by using them and that is my opinion, like it or not.
What about rather have a bulky HD compared to a few more slimmer/lighter/less-bulky batteries? You've moved the goal posts entirely to better support what you're saying. Most people would rather be cordless than corded; HD packs, depending on application still wont last you all day, you're going to need more than one or you'll need power to recharge them. Sure you'll need less to (as I suggested) run a 9" grinder but you certainly won't get away with only one for the average day at work. Consider it 4-5 (heavy, bulky) HD batteries, or 4-5 compact batteries and a charger.
It offers little benefit given the cost of them and greatly reduces the compact and lightweight factor that used to be a massive selling point of cordless tools.
As I've said, I work along side people that use tools that need a lot of juice, if you offer them a £200 angle grinder + £1000 worth of HD batteries or a £120 corded model... I'll let you decide which one wins.
HD packs are not only about runtime tho. Current Makita batteries have a real chance of overheating on the 9" grinder and the chainsaw. Overheating before you get to drain them. HD packs would make these tools more viable for many people. At the moment when someone comes in for the 9 inch grinder I have to ask alot of questions of my customer to make sure he understands the limitation of the tool. Limitations which are only there because of the battery.
And as a salesman it's indeed the truth that I'm getting the question for bigger packs more and more. Most people don't think ahead that a bigger ah battery will also be heavier. The marketing behind flexvolt for example just works. For most people the ability of going cordless outweighs the added bulk of bigger batteries.
If I were able to sell the 9" grinder with a pack of 9 or 12 amp batteries then my sales talk would be alot easier. Wouldn't have to worry about any overheating. I could tell them to expect thesame kind of use as a 5 inch grinder ( which pretty much everyone already has )
So in short: are HD packs absolutely needed for Makita ? The answer is 90% no. 10% yes for a few specific tools.
Would it hurt Makita to start giving their customers the option ? Wouldn't see why. People like big numbers and they would sell.

Really doesn't bother me. With the weight and bulk of some of the newer HD packs coming I'm struggling to see the benefit of cordless tools. Can't remember the last time I didn't have power, besides the minor inconvenience of having to run an extension, I'd prefer my tools to be compact and lightweight for all day use, not clunky, bulky and heavy with a battery the size of a house brick on the end of it. .
And for the benefit of what, 9" grinders than can manage 20 or so minutes of runtime on a near £300 battery? Meh; vanity project, no more practical than carrying 5-6 batteries and a charger around with you.
But that's your opinion of of course. There are enough people that rather have a bulky battery then having to carry around and plug in an extension cord

Makita Battery cell 20700

Your story isn't correct either.
Charge cycles isn't the only thing that deteriorates battery cells.
Heat is the most important factor. Thzts also on battery University to quote your source. 21700 cells can output more current for less heat buildup.
Less heat = longer lifespan.
