Yes sir, thanks Mr.D, yes thats exactly what I meant. What I was meaning is hoping they dont mean to push the metal saw out and considering its their new circular saw. I thought it was brushless some how. I'm still trying to do research and see can I switch a wood blade on and use it as a regular circular. So thats for the huh? reply for dwain.

Thanks Abimarssani. dwain: I also heard brand new battery pack need some time to wear in to the best performance. Then after a year or so depends on the useage, it drop about 10 to 15%. It will continue dropping another 10% each year. But again that just what I heard. Not 100%. Not saying you should that. But you want a complete fair test, it might have be with either 2 brand new pack or 2 pack were similar time purchase around with the same useage, then it might come out with a better results. By the way. My wife bought me the DEWALT DCS355D1 20V XR Lithium-Ion Oscillating Multi-Tool Kit from amazon for my early birthday present. And it just got in today. I have a brand new never be use of charged 4.0 pack and the kit came a brand new 2.0 pack. I might do a comparison on them and see What's the results on the dcs355 with the same way you test on the other tools.

Here are part of the article I copy and paste from the link I put in my preview post, Maximum discharge rate. One brand’s latest 18V battery packs are built with cells advertised as having a 20A max discharge rate (22A on paper), and their previous battery packs were built with cells rated with a 25A max discharge rate (23A on paper). A homeowner brand will not equip their tools with Li-ion batteries rated for 20A+ max discharge rates, and pro-grade brands will not equip their tools with cells rated much lower than that. As a reference reminder, a battery with a 2.0Ah rated capacity can deliver a 2A discharge rate for 1 hour. Thus, a 20A discharge rate would deplete the battery charge in 6 minutes. When is the last time you saw a consumer-grade cordless rotary hammer? Angle grinder? Band saw? Consumer-grade cordless tools don’t have the same power requirements as pro-grade tools, and so they don’t require top-dollar battery cells that can deliver the highest maximum discharge rate. Minimum operating temperature, or rather minimum operating temperature and battery performance at those temperatures. The best rechargeable Li-ion batteries I have seen thus far can deliver 60% of their rated capacities at -4°F, and 80% at 32°F at a 10A discharge rate. A 10A discharge rate would deplete a 2.0Ah battery in 12 minutes at room temperature (100% capacity). Battery packs that probably won’t be used outdoors in all weather conditions don’t need cells with good cold weather performance. Life cycle. Samsung’s recent INR batteries maintain 60% or greater charge capacity after 250 charge cycles. More life cycles means longer usability and less frequent replacement schedule. Minimum/standard capacity. A 2.0Ah battery won’t necessarily deliver 2.0Ah charge capacity under load. 2.0Ah is the nominal capacity, but during high drain discharge, the actual capacity might drop. Charging time. Higher performance batteries can usually be charged at higher rates, although active cooling is required to achieve the maximum charging rate.

I did many reseach about that. But no one seems to know what exact cell they use for them. Best I came across is dewalt using the red Sanyo 18650 2000mAh 20A max high discharge rate cells. But I heard the older one use even higher discharge rate cell. (Not meaning the pack is going to be on 20A discharge all time, it's depending on circuit board control when different temperature, how warm up is pack and many other facts.) I also think that could be one of the reason the result came out kind of strange. I remembered you mentioned about one of the battery pack is from US and the other pack you bought it used. It could to cause some strange result as well. Im not sure tho.

Does anybody know or hear anything if dewalt making a brushless circular saw or new model anytime soon? Or I should get the DCS373 Metal Cutting Circular Saw if my missing circular saw decide to pop out someday;) Do anybody tried and think I can just change a wood blade on it and use it as a regular Ciruclar saw? I think the dcs373 is much more bad ass with led light and all. Just want to know if anybody use it to cut wood or pvc. Maybe the rpm is too high for that or complete different thing? Feel free to light me up some info. for it. Thanks.

Same here. I have been waiting for the new xr circular saw to come out. Hope they are not using the dcs373 20v metal cutting circular saw consider their new xr line for circular.. well it is not brushless right?

I really wish we have a harbor freight here on the island. But I dont even think we get onemin the whole Hawaii;(

The deal must be over by now. Price went back up already. I bet it ended on march 31th. Thanks post posting the deal.

Thanks for the advices Jav, that just make my decision. Lol... I was thinking the same. I already have a simple little B&D corded jig saw. And my 18V deawalt only sitting in the case for pretty. I'm ready to sell all my dewalt 18v line and move to all 20V since I already have 11 20v batteries;) I down to the 1 jigsaw, 1 grinder, a shop vac and a radio, 2 brand new restored xrp batteries are 18v. I can sell them all to use the money for to buy the oscillating Multi-Tool kit and another circular saw since mine has been missing for over a month. Then I will be set for now from the 20v line. Hey, have you hear anything if dewalt making a brushless circular saw or new model anytime soon? Or I should get the DCS373B Metal Cutting Circular Saw if my missing circular saw decide to pop out someday;) Do you think I can just change a wood blade on it and use it as a regular Ciruclar saw? I think the dcs373 is much more bad ass with led light and all. Just have hear anybody use it to cut wood or pvc. Maybe the rpm is to high or complete different thing?

Hi, thinking about selling my dewalt my 18v jigsaw and buying the DeWALT DCS355 20v Max XR Brushless Oscillating Multi-Tool kit. I dont use my jigsaw much might use it twice on small projects since I bought it 2 years ago. Going to do a remodeling for my living room with pergo wood laminate flooring. I think it would be handy. But what do you guys think should I sell my 18v jigsaw to use the money to get the new 20v Oscillating Multi-tool. Can I use it as a jigsaw? Give me some thought. Thanks.

Hum. Thats strange the batteries wasn't a noticeable difference on the useage. My thought is since the circular saw draw higher amp power then the drill or impact driver. I assumed the the 2.0ah pack will be more noticeable decrease on the battery juice than the 4.0ah. I have heard using the 1.5ah pack on the circular saw would drain the pack way faster than the 3.0ah pack. For the fact I'm thinking it could because of the circuit board in the pack is pushing more power using higher amp to spin the motor faster than and create higher speed. I dont know it could cause the small pack cut faster on speed thou. I find something are kinda interesting me on how all tools brand use different brand cells. Like Sony, Sanyo and Samsung 18650 lithium ion cells. Feel free to check out this link to get some ideas. http://toolguyd.com/power-tool-brands-dont-make-their-own-batteries/

Nice update Dwain. So, when using 2.0ah pack finished off and cut faster than the 4.0ah pack on the circular saw! Thats surprised me. Did you notice the difference on the battery useage somehow in the test?

Hi Dwain, I put in some thoughts of how to do a fair test on the circular saw with the 1.5ah and 2.0ah xr vs. 3.0ah and 4.0ah xr big pack. I remember the most circular saw requiring to use the 3.0ah or above to get a better performance on the tool because the motor on circular draw much more amp power from the battery, not sure if I'm correct on that. And I also remember I used the 2.0ah xr small pack on the saw to make 2 5ft cut on a piece of 3/4" plywood forward by cutting some 2x4s with no problems and 2bars left on that 2.0ah xr battery. (Note: when I bought my set of the xr combo kit only come with 2x 2.0ah pack and Home Depot was running a deal for a free bare tool with the combo kit.) Thats how I got my circular saw free with the kit. Also remembered seeing the Y.T. video from TIA about the saw. Dan mentioned its better to use the 3.0ah on the saw to give better performance which it came with the kit. Thats why I went and bought a 3.0ah battery just for the saw. I'm not 100% on how to test them to be fair on this fact at the moment. And I have been doing a lot of researching about powertool batteries lately. Trying to find out how they work and what's the best way to get the best use out of them. I have 5x 1.5ah, 2x 2.0ah, 2x 3.0ah and 2x 4.0ah total 11packs I have. But I only have 6 20v tools now included the missing circular saw 7tools and 3 changers. And I don't use all 6 or 7 tools all at once. So 8 batteries will be more than enough for me. Also heard if they dont get enough used or charge, its like it doesnt get enough work out for them. The batteries will go bad or shorten the lifetime by sitting and not being use. I'm has been trying to sell 3 of the 1.5ah or trade them for another bare tool. But no luck for the pass month and half. Anybody has any thoughts on the battery life or useage? Feel free to share your idea or experience by post a comment directly to me or here if Dwain don't mind. Thanks

Nice comparison. Even bosch has the extra 50rpm, But I almost sure Milwaukee will win that one. Because of the 4.0 pack and bigger pack seems like giving more cleaner power on impact driver than the small 1.5 or 2.0 packs.

Ha.. thats good to know. I would of thought the same. Didnt expect impact driver would give more clear power with the big pack. I would do the test on ciruclar saw. But it was missing for over amonth now. Might have to buy a used one somewhere soon. Good post tho.

I love my dewalt 3 speed impact driver. I'm a apt. manager/ handymen for 7, 8years now. Also do consturstion punch work and detailing for many new homes, pretty much I'm a do it all guy there. Finally decided to upgraded from dewalt 18V ( I owned 13 tools from 18v line) to dewalt 20v xr brushless line last year. I was debating with Milwaukee Fuel, Dewalt XR and Ridgid X4 at that time. which platform should I move to. I do some reseach ahead online and went to Lowe's first and they only sell dewalt out of the 3 brands. But all dewalt xr line were out of stock. So I went to homedepot. They got it all. At first I almost go buy the Ridge X4 5pc combo set because of the price and lifetime warranty. But even that they aren't brushless and feel cheap made. Looking at the Milwaukee Fuel 2pc combo set with a free of choice bare tool speacial (sawzall, circular saw or 3.0 batteries.) for $349 and the dewalt xr 2pc combo also a free bare for $279. For that $70 different at that deal. I picked up the dewalt xr impact and drill combo set with the free 20v ciruclar saw for $290 out of the door. Then a week later a guy is moving outta the island and selling a set of the dewalt 3 speed impact drill set for $100 on Craigslist. I went and pick that up in 30mins. Every since I have been in love with it beacause the multiple duty tasks on the 3 speed function are great for what do. I carry it on my truck everyday and everywhere;) I think I did a good choice on my dewalts. I own 6 of 20v tools now, I have 2 xr impact driver, the xr compact drill, the xr 3speed hammer drill, 2 led work light, my ciruclar saw has been missing over a month now (dont know how) With 11 batteries for them. Dewalt 20v xr does it good for me. I'm proud to be yellow. Not only because I'm asian;) good luck for your choice buddy...
