Only way it would work is if there is an active pfc circuit. You find them in larger power supplies in computers etc... But then it usually states 100-250V. From the pictures, it doesn't looks like there is such a thing tho. So no, it won't work. And remember, they don't change the layout unecessary, and the designs is expected to be almost identical. The difference is in how the transformer is wound, the input capacitors rating, and circuit breaker. And without the active PFC circuit, it would probably blow up. An Active PFC circut in such low power equipment would be a bit unecessary and expensive. So it is not really something I would expect.

I'm not even sure I need a lawn mover. It looks like automatic robots are taking over the small to medium large lawns. Not sure if lawnmovers is a thing of the past in a couple of years? What you guys thinks?

The coffe maker was one of the first makita tools that was introduced to me. And the local dealer also sold their cycle and heat vest. They didn't recommend the coffe maker though. The coffee wasn't really that good they said. The cooling systems is pretty rare up north here. I would be thrilled to have a days worth of sunshine, and cooling wouldn't be very necessary. But a beer cooler. That's nice. If only I had Bosch 18V. ^^

I doubt you'l NEED that high RPM. Either use a better drillbit, let it take more time, or just us a completly different drillbit-type. But for answering your question, I don't think using a drywall screwdriver will be especially good alternative, and a lot of wobble/little power. Not that I have tried though. You could buy a high quality battery drill that is geared high, like this festool drill: http://www.highlandwoodworking.com/festool-pdc-quadrive-cordless-drill.aspx or http://www.amazon.com/Festool-PDC18-5-2Ah-564597-Cordless/dp/B00XJS58BG/ref=sr_1_1?s=hi&ie=UTF8&qid=1451330749&sr=1-1&keywords=Festool+PDC18 3800-RPM, and it is designed for use with regular drillbits, and has very little wobble.

How much charge you let in, storage temp and charge you store they on is what mainly determines how many cycles you get. And by alterning theese it could be from a couple of thousands, to just a few hundred . To counter this, the makita charger has active cooling on the batteries, like most other quick chargers, and can therefore charge much faster than a passively cooled one without heating up. Also, other protection mechanisms operate to keep the batteries condition best possible (too low and to high temp etc...) And you see quick charging like that in a lot of products. From the high end Teslas to the smaller and cheaper products. Also, chargers that charge slow can and wiøl usually be a lot cheaper to make. And 45 mins on a 5Ah battery is not THAT quick in today's market. Li-ion is much better than older battery techs on that point (and most other too).

Would not have thought that a small impact driver would have anything in the range of 10 % decline, but sure, I have not tested it so I just might be true. In theory, that is to be expected. Since the voltage drop would be twice as much at the smaller compact batteries. Probably in the range of 0,5V on normal 5Ah batteries, and 1V on compact batteries at peak load. On a fully charged battery, that means the motor would only see around 19,5V VS 20V. And certainly, the motor performance would be a bit lower. This difference rises with rising load, and thats why I didn't thought drivers would pull enough juice for it to be relevant. I'm planning a larger test next year with some pretty decent test equipment on a couple of makita power tools. More focused on just the fun stuff, numbers. Measuring amp draw, voltage, input power, resistance (ESR) in batteries, charging curve, and a more sophisticated testing rig for power output. At least, thats what I'm hoping to do. Really seeing how the equipment differs at different loads. Really putting a lot of theese interesting questions to rest. Also, if accuratly enough, it will be possible to really find the sweet spots and weak points. Sad part is that I don't have more power tools to test. But that's a worry for another day.

The two row batteries is a nice all-rounder, but a single (2ah) and triple row (9ah) is nice in a couple of cases. And no, in easy words, it doesn't really matter if you have two batteries connected in parallell or if it's one that connect it in series. Or that you have one large pack. What count is as some people have said, is the load each cell sees. The easiest way is just take the total wattage of the tool and divide it between total number of cells. This is the easy way. Sure, there are a few smaller differences in reality, but it is barely worth noting in this context. The example of a tool that connects two batteries in series would be the most efficent and best. Since it will have slightly lower losses in the wiring/winding, and could get away with slightly less copper, making the motor slightly lighter. The two other examples would perform identical. If you have two batteries in parallell, or just a double sized battery pack. In this context, the 9Ah is just an extra row, not two, so it will be the inferior in every comparison, except weight of course Ps: Connecting two batteries in parallell would half the total internal resistance. Just like using two resistors in parallell.

The angle grinder would just love a 9ah battery. They drain the 5ah battery so quickly, the other battery you just drained, doesn't even have time to start charging (cooldown mode) before you have drained yet another one.

Yes of course. Not only adapters, even an longer extension rod will have more than a short one. Not sure how much tho. An extreme example are theese torque limiting rods, that is "calibrated" to become springy when it reaches a certain threshold. I would guess it happens on any metal, just not as much. But the question is, is it any practical difference on the quality of the adapter? I have some cheap ones, and haven't been able to destroy them. But then again, it might limit the performance more than it has to?

Question: Impacts rely on that the socket and fastener is adecate stiff, (opposite of springy) to get the torque you are paying for. And I wonder if cheaper hex to square adapters would limit the max fastening torque in an substancial maner?

Lithium-ion cells will: 1. Always deteriorate, but the rate is highly dependant on the charge and the temperature of it. Around 50 % charge is the best, and room temperarature, and then you would need to charge them once in a while, since the charge will drop a little bit in storage. But of course, this is not very practical. But then again, life span is very high like this. So not any problem at all to lower it a bit. By for example always charge the batteries 100 %. 2. If you use the batteries in the cold, or overheat them very often, you would drain the life quicker (in an exponential maner). But even so, the automatics in the batteries usually protect themselves to do any very high damages to them. 3. Would hold a lesser charge at low temperatures, so your batteries will have a lesser working capacity at low temps. Especially sub-zero. So you could actually get more of the charge if you use some of the power to heat them up a little bit. Just like Tesla's batteries in the Winter-pack. I don't know about milwaukee, but the Makita charger don't want to charge the batteries at too low temps or high. Becouse it would drain the lifespan too much. And people would get angry. Good thing is, cold batteries will heat up quickly at low temps. So you just have to work quick.

Woha, thanks! That explaines a lot. The devil's in the detail. Did not occur to me that it was two different brands/branches at all. And yes, the saw's I was looking at was saw from Skil, not Skilsaw. ^^

Wonder how it would cope with metal chips and a few "piles" of dust. Would be awesome to built a new workshop with nothing on the floor (easy acces to the whole area), and a robot like this that cleaned up after you. And if I was in need of fresh batteries, I just borrow one from the robot. Now I just have to wait for robots that can put all the tools that I have used back to their respective place.

Just a stupid question, but here goes: Here in Norway, the skil brand only sells the cheapest and worst kind of equipment. Sometimes even cheaper than other chinese no-brands. Skilsaw circular saw costs well under 50 bucks. And 90$ for their higher end shit. But here at the forum, and in USA in general, it is regarded as a fairly good brand. Why? Do they have a very large price and quality span, and only ship the shit to europe? Or is it only their older stuff thats any good? Or anything else? This has, frankly speaking, made me wonder a couple of times. :s Whats going on here?!

Hehehe, I sure will. :-) I suddenly realised that this, combined with my thermal imager, means I'm slowly becoming the ghostbusters.

Holy shit! This never occured to me. But at least I love the idea of having the vacuum on the back when cutting a lot with the circular saw. Or even when using different equipment. It might even keep me warm on the back. But ding, now I want both..! No, I NEED both!

I might have mentioned it earlier, but if you order the makita circular saw from europe, you even get it with 7,5" blade (190mm). example: http://www.toolstop.co.uk/makita-dhs710zj-36v-cordless-li-ion-circular-saw-body-only-accepts-2-x-18v-ba-p68767

At least the first set with charger and batteries should be with the same voltage/frequency as you power grid. :-)

Makita's 36V system uses the same 18V batteries (2x18V). So if not weight is very crucial, but power and battery-life is important. Makita wins hands down on: - Circular 7,1/2 inch blade (it may be 7-1/4" in the states if i remember correctly) - SDS plus For the other normal 18V equipment: - FUEL 2 Hammer drill is very similar in performance with the makita XPH07. THey each got its pros and cons. - The best 1/4 impact is probably milwaukee, but then again, Makita's compact impact wrench (1/2") easily beats it again, and milwaukees counter parts. Not only that it got a lot more torque, but love that 1/2" square torx/PH/Pz is more compact than 1/4" adapters / bits (and I can easily use 1/2" sockets without adapters with the same tool). - I'd like an explanation why milwaukee got better 5ah batteries than any other. Just wondering, since that is a very new claim to me. - Charger is easily makita. For 18V, their charger is the quickest and as good as any other. I got no idea on the jigsaw though. Mafell and festool seems just so awesome that it overshadowes the others. I think the correct name for it, would be love. ANd the reason I dont look elsewhere. XD I have no comparison on price between milwaukee and Makita. But from where I live, the latter is more popular, and therefore got more competition and better prices. Might be team red is cheaper in the states, and got better offers. Also, Makita at least got the reputation for the largest 18V and 18Vx2 equipment.

An extra dc-dc inverter would probably not take up much more space inside the charger. You'd still could have the same voltage regulator and computer stuff. Same transformer, PFC and filter circuitry etc... It would not need to be more than 10-15 % more expensive, tops.

Sad. Here in norway, it doesn't matter if what you sold was "as is". If the condition is substansially lower then what you could expect, you should have a pretty good case. You can't just write off your responsibility just like that.

Ahh thanks for the correction. Not sure what I was thinking. Had to be wishfull thinking. Even my first post in the thread mentioned it had the same size as my circular saw (7-1/2"). But sure, for a compact unit, it's enough. Though, not a real replacer in the workshop.

I have no problem using a bit more money for quality, functionality and practicallity. But with just a 10" blade, it can't really cover for the largest saws. Not that I normally use large timber, but save time and rise acc. by cutting pieces at the same time. But then again, maby 10" is enough? All I know is that the bosch pcm 8 is in need for replacement. :-D A 210mm blade is way to small.

If I had it, I probably be to scared to use it...

At least you save the cost of buying new blades. Same blade size as the cordeless circular saw.
