1. I feel the same here, in 18V line the 5A are noticeable better than 2.5A batteries. But in 40V appears to have no difference at all have a 2.5A or a 4A battery. Even in the 40V grinder that sucks all power from batteries very fast. My 40V grinder with a 2.5A is better than my old 18V x 2 grinder with TWO 5A batteries! Not only better, like 1/3 more power in the 40V line. The new 40V motors are purpose build with stronger rare Earth magnets, bulky cooper windings etc. it's not just a 18v motor changed to work in 36v. I was septical at first but at least in nailer and grinder the 40V makita are awesome. The 40V grinder is better than the 60V DeWalt. And yes, I had used both to compare. It's not only about voltage,. it's about well build motors.

2. Amp hours equal runtime not power.

3. I reckon they're only using 21700 cells because a 4ah 18650 battery wouldn't put out the amps required for the tools

4. Since P=U x I, this tells us that higher voltage require lower amps. Thus 18650 cells will work just as fine:)

   Also, thanks for this great review! I was hovering with the mouse pointer over the 4,0ah version, but settled for the 2,5 :).

5. makita is going to back and supercharge their 12v lineup as they phase out 18v. for the lighter and yet powerful tools.

6. Does the Hikoki have the same situation with their 2.5 and 4.0 36V
   I have more power with the bigger battery

7. Would the 18 vs 21 cells be that the 21 will survive more discharge and charge cycles?

8. I did it, dude. My toes are officially wet. I ordered the drill/impact kit (it was only $50 more than the drill kit) that includes a pair of 2.5ah batts. Most of the kits on offer have 1 4ah battery, or a 2.5 ah + 4ah. Your vids literally swayed me. I'm in no rush to buy up XGT stuff, but I'll be grabbing some skins when stock gets stabilized. I'm banking on that 80v blower and 40v 6-1/2 I have in my imagination.

9. Like the no bullshit approach to your reviews. Weight distribution with equal power counts for a lot in my book.

10. nice going.

11. Makita says that 40v batteries communicate with tools. Maybe for some reason Makita wants those 21700 cells to deliver less power down the road while 18650 can still go full capacity continuously. Maybe battery health is a reason for the performance drop or maybe 21700 chemistry is not as good as in 18650 yet. Very interesting test though and proof that real life usage is always different than advertising. I am going to stick with my XLT-18V system and don't think 20-30% max. performance increase with 40V is worth the 100% price tag right now. Maybe in 5-10 years.

12. 21700 kick harder than 18650 in a non-controlled full discharge environment, the 2.5ah and 4ah are using Samsung 25r and 40t batteries respectively and tests show higher current output and lower internal resistance in the 21700, but should all be irrelevant as the CPU in the tool should pull equally from both batteries, so the 21700 will simply run cooler as it has more headroom. Testing both batteries at two bars left does not equal 50% charge on both, two bars covers a range as wide as 40-60%, one battery could have been at a significantly lower voltage than the other and the tool will reflect that in it's performance by dropping off in rpm or torque etc. It's strange that the 2.5Ah seems to perform better, must have something to do with Makita's battery management.

13. Stored energy:
    18V * 4AH = 72WH.
    40V * 2.5AH = 100WH.

    Also higher potential energy, 40V >> 18V.

14. Very interesting video I like makita tools

15. It would be interesting to see the Battery Breakdown and see what cells are exactly in both batteries.

16. The truth is the 18V LXT stuff is awesome and not at all worth ditching for 40V "max" stuff that costs more and will only be outdated as soon as solid state batteries make their way into tools (which they will). At a certain point, the only thing accomplished by stuffing more and heavier li-ion batteries into a pack is…you get a heavier more powerful pack. Which on most tools just simply isn't necessary. It is nice on a few tools, for sure. Especially the outdoor power equipment, chain saws, etc. But on the vast majority of tools it is just dead weight. I'd rather have lighter tools and switch the batteries out slightly more often, than lug around heavy batteries just to get a bit more power that I probably didn't need anyway. Just wait for solid state batteries. In 5-10 years there will be an entire new solid state battery platform from all these tools companies, until then, I will use and enjoy my perfectly functional LXT stuff. Like who wants a 40V compact impact driver? It's completely pointless.

17. Would really like to see the 2.5ah compared against the 18v 5ah.

18. I totally agree the 2.5 ah is better weight wise & speed even on the 3/4" 40volt impact wrench.

19. Can you cut the tab on the 40 volt to make it work on the 18volt?

20. Is dust ingress at all a consideration with batteries?

    It's always comforted me that both ventilation openings are covered by the machine whilst in use with the 18v batteries.
    Yet the 36v batteries have "always open" holes in the bottom.

    There's no moving parts in there, and the electrical connections are (I believe) all potted or covered.

    So the only difference would be decreased cooling over time as dust builds up on the cells, right?

21. I questioned makita directly on the performance of my saw and 4ah battery. They accused me of just having a moan. Turns out I was right. Cheers my dude!

22. Hi! So can I assume the reason you tested all the 40V tools on 4amp is because 2.5 wasn't available at that time in New Zealand… ??

23. Why do they call it 40vmax when it's 36v like you said.

24. Enjoying these, I think your little interjections are hilarious

25. Wow!

26. WTH. What was makita thinking by doing this. It has to be software controlled. Multimeter test them. Milwaukee saws n everything runs stronger with 21700s. Except led bulbs.

27. Is it worth "upgrading " to the 40v line up? Nothing at all wrong with my 18v stuff just don't want to let the Kardashians get too far ahead

28. Great video. In theory the Samsung 40T 21700 cells should have less internal resistance than the Samsung 25r's 18650 but the 25"s can do 25amps each under load and perhaps the BMS and temp sensor will not allow the 40ts to maintain 25amps sustained….

    Thumbs up

29. Awesome video as always mate. Really helpful and informative 👍. You the man! 😉

30. this is interesting 🙂

31. Awesome knowledge

32. Hello there fellow Kiwi. Would you be interested in seeing if the Hikoki equivalents have the same issue? That of the 2.0/5ah performing better in power tests vs their 4ah counterparts?

33. Another great video! Don’t let the naysayers get to ya! I found this very interesting, and a bit confounding? I think the 40 Volt 2.5 performs well, due to the fact it has two rows, that run in series, vs parallel. Why the 4.0 didn’t do much better, is a conundrum? I have noticed a speed and power difference on some tools, from different manufacturers, with the newer cells, and then no difference on others. 🤔🤷🏻‍♂️ Guess it depends on the battery and the tool, and how they “talk” to each other? I am thinking the 21700’s will get better and cheaper with time. It will be really interesting to see how this technology will improve! Big thumbs up! Cheers Mate! 👍😁🇦🇺🇺🇸

34. was you just complaining that the battery was lasting too long?! i think thats a first

35. Wish that Hikoki would send you the 36v power saw. I'd like to see it against the Makita. I think the Makita will be better, but by how much?

36. I think i knew that the only real appreciable differences between the two would be run time and weight. The thing i take away from this is how good the grinder and saw is. So powerful. That cordless grinder is fit for a welder.

37. Very interesting. There is still some fight in the old 18650 Dog yet!👍

38. It'd be awesome to see what brand/model of 18650/21700 cells their using in these.

39. that's soooo weird that Makita claims the 4.0Ah has 1540W output power while 2.5Ah has only 1150W. Makita Japan sells grinder with 4.0 batteries but 165mm circular saw with 2.5.🤔🤔🤔
    btw Makita still making 18V+18V tools for heavy duty work since 2*18V 18650 batteries have way more power than the single 40V 4.0Ah's

40. The base of your saw is different to the base of mine , the front right side on mine is a angled at 45 degrees not 90 . Strange !
