Lifetime subscriber here!... Love that you include the battery rocket in your intro now. That was one of my favorite videos of yours. Not only did you prove the tabless cells, we now know how to make a rocket!😅 Cheers Thanks for all the great content
Most likely the fuse is blown. Measure voltages where the cells first meet the PCB. Then move the probes one component at a time towards the terminals and eventually you'll find what's popped.
I believe the xgt batteries microcontroller has the ability to blow the fuses as a last resort in the event of an over discharge / uncontrolled over current event. Wonder if the user was using it with some sort of dumb adapter and over discharged the thing resulting in the fuses opening.
14:50 whenever you see voltage dropping like that, there's just residual charge on the terminals. Think of them as very small capacitors and your multimeter is drawing a very small amount of charge by measuring the voltage.
Can't make a battery much slimmer than the 2.0 or 2.5 ah. A 40v max battery utilizes 10 cells, so that limits how compact a battery would be. A 1.5 ah would be virtually the same size as the 2.0 or 2.5, since the cells themselves are the same size
@@jeffalexander1151 You can use 10440 (AAA) 500mAh, 14500 (AA) 1200mAh or 16340 (CR123A) 900mAh lithium ion power cells . Better is to use 12V or 18V tools if you want smaller tool battery .
I have mostly 2.5Ah batteries. Diy er and don't use my tools that often until now. Will get a stick vac or something to get more use out of them. It would be a shame if the batteries got less and less power because of not enough usage. Thanks for the tip!
In reference to the wattage for the batteries, as in the 2800w for the 40v 8ah. Thats 70-80 amps, just wonder how much power can the external battery contacts actually handle, the contacts that interface with the tools. I think I've seen videos showing Milwaukee batteries over powering the contacts, just seems like the weak link to me, especially as they get dirty and oily
I've pulled 150A from Milwaukee batteries without melting them. Melted Milwaukee batteries happen due to vibration making the terminals break contact rapidly. Also the XGT batteries have 4 contacts vs most other brands only having 1 or 2
Its definitely a weak link on the milwaukee tools, it seems to be an issue on all their batteries. Only time will tell with the 40v stuff but I'd wager it'll be fine unless they start putting out tools that pull more power than that new jack hammer
Bosch and some Milwaukee do this, too. Definitely the Dewalt flexvolts. Nearly everything a tool company releases is covered by a design patent to stop people from just straight up copying their design.
As I mentioned next to the earlier video, BL4025F has been discontinued and will not be coming back (according to Makita Lithuania, personal message; others could send similar inquiries as well to their local Makita representatives). "Discontinued" sounds strange, because they were not on sale, but, in fact, at least one German website was selling them for a while (Loechel-industriebedarf - still is, 8 days delivery, 163,49 EUR ;). Not sure if they would deliver anything when ordered, however, online stores do contain errors like that.
@@toolscientist They included these batteries in multiple printed regional Makita catalogues of various designs. That was not a leak, they should have been on sale a long time ago, imho. On the other hand, even if the explanation I was given by the rep is correct, they could still (probably) release them looking identical to those pictures, but with something slightly different inside. Who knows... Makita, at least here in LTU, has terrible PR. Two of their latest promotions are top-grade BS (exist only "on paper"), and their pricing is all over the place, to put it very mildly. I sincerely can't understand American complaints about how expensive Makita is there, because they at least have *actual* sales. And to top it off they're not leaving batshit crazy russia/belarus. I, personally, regret going for their 40V platform.
@@k.squared Im from Germany, i could order one just for the heck of it. But, Im sure when I order it i get an email saying ''not available, 8 days shipping is just a phrase''. Or should I? Maybe Makita already has another battery technology in the works and they go even one step further than just tabless cells. But i doubt it
Can these batteries be used for other things or do they communicate with the Makita tool and prevent other uses? Does anyone know the max continuous discharge amp rating? I need a small and lightweight 36/40v battery to power an electric motor. The easiest way would be to use such a tool battery. But I need to be 100% sure I won't get thermal runaway due to asking too much from the cells....
Здравствуйте!А не подскажите,когда у макиты выйдет ударный гайковерт на 40в с посадкой на 1 дюйм,а то конкуренты наступают на пятки. Заранее благодарю!!!

Mr Tools 2024. 😂😂😂

13:05 if the microcontroller was cooked, you wouldn't get anything from the battery checker. Likely the curious owner wanted to read what chip it was.
Awesome investigative work as always, can't wait for the next part, thanks! 😊
They need a slim battery for impact drill, even if it’s 1.5 ah at 40v

@@pete_lind none of those have high enough discharge rates.
@@jaywelker5566 yep. only option would be custom lipo prismatic cells like dewalt used in 1.7ah
When is makita going to advance battery tech of lxt batteries?
Hoping they start selling the BL4040F in North America soon. Any idea what that timeline might look like?

that is why they made a new battery platform, xgt has bigger contacts than lxt, milwaukee, dewalt etc...
14:20 Iirc Makita owns the patent for this style of protection
Bosch and some Milwaukee do this, too. Definitely the Dewalt flexvolts. Nearly everything a tool company releases is covered by a design patent to stop people from just straight up copying their design.
That opening scene.😂

Interesting, they haven't even been properly launched.
@riba2233 I'm sad now. Hopefully it's just some sort of double-bluff due to them accidentally leaking it.
@@toolscientist yeah I really hope it will be a real thing!

The gas expelled when burning a lithium ion battery is very dangerous to health and fatal in small quantities, Hydrofluoric Acid.
Do you know if dewalt is using any tabless cells in any of their batterys? How could you tell without pulling one to bits?
not yet but they have announced them
I heard if you squish the battery in a vice nothing happens? Maybe worth a try?
The new tables cells on batery is prove on the drill or grinder . Bosch got the same product tables cells an they promising 60% more run time
Over two grand worth of Makita batteries
First
3rd actually.

Заранее благодарю!!!
вопрос к любителям макиты, сколько циклов выдерживает аккумулятор макита?
It is not a fixed number, but certainly in 500-1500 range. Depends on how you use it.
2000 циклов
Just here patiently waiting for a framing nailer release video🫡🥹
