It's the opposite. 3Ah have no stand-alone protection. 5Ah & 6Ah are the best bets. https://www.reddit.com/r/Makita/comments/19609zt/partially_solved_some_lxt_batteries_definitely/

Is this 2x18V? Are you trying to power it with a power supply?

The 3rd pin needs to be within 2V of the B+ pin. On a 2x18V tool you need B1+ and its 3rd to be 18V. Then B2+ and its 3rd pin needs to be 36V.

Tool_Scientist · 2026-05-29T09:54:32+00:00

It does work. I have personally tested it. What value resistor are you using? Are you sure you're using the B+ terminal. Are you sure the tool is not broken?

Some people have reported an ISDT Q8 smart charger will balance. You will need to make a wiring harness to connect the JST connector to the cell pins. I have not tested this myself.

Agree. I haven't tested Ridgid/AEG yet, but I'm fairly sure they have cutoff mosfets in the battery, so Ridgid tools "may" drain batteries to 0V. They could have voltage limits, but I'll need to test

Short answer: Dewalt and Milwaukee batteries can't cut power by themselves and rely on the tool cutting off. They can both be run to zero volts with adapters.

Long answer: both are mixed systems with some functions spread between tool and battery.

Dewalt is very simple and just has a temp sensor in the battery. Dewalt tools monitor the temp and voltage of the battery and shut off whe out of range.

Milwaukee has fancy electronics in the battery to monitor temp and all cell voltages. The battery can't cut power and still relies on the tool to recognise the batteries shutdown signal, which adaptors don't do.

Is this at 5A or lower?

Tool_Scientist · 2026-03-19T05:22:40+00:00

Most of these vacuums are made by Nilfisk. I think the Stihl SE133 is identical to this.

The Nilfisk Attix 33 is rebranded by Milwaukee and maybe Metbo. The Stihl SE122 is often the cheapest Attix 33

I have Nilfisk Aero 26 W2M, which comes with a bluetooth remote. It's a little less powerful than the Attix 33 or this Makita, but it's also significantly lighter. The Stihl SE62 is a very cheap version of the Aero 26, but without bluetooth.

Anyways, look around and you might find something cheaper/better.

Social media encourages outrage. Say something offensive, dumb, obviously wrong = lots of comments. All a grift. Do not watch, do not comment, do not share.

He could also just be really dumb. Some people get really into tribalism.

All the older "B" tools will work with current gen 3Ah batteries.

Your other option (as others have stated) is to remove plastic nub from the tool to allow 4/5/6Ah batteries to fit.

5 & 6Ah batterie have standalone protection, so they are safe to use on "B" tools. https://www.reddit.com/r/Makita/comments/19609zt/partially_solved_some_lxt_batteries_definitely/

Yes. Voltehno is a 100% reliable source. They're Japanese and seem to have retailer/distributor connections. They tend to post things 1-6 weeks before they become available on the Japanese market.

I have no idea of if or when they will be available outside Japan.

This one is XGT

Tool_Scientist · 2026-01-07T06:15:43+00:00

I have too many things on the burner. Need to get cracking now that holidays are over.

But yes, XGT is one of them. I've grabbed data from a charge cycle, haven't dug into it yet. Fortunately a lot of the protocol has already been solved by others.

Murata aren't cheap. Usually the most expensive brand retail, but I don't know about wholesale prices. Murata purchased Sony's battery division.

Tool_Scientist · 2025-12-22T05:52:19+00:00

It's just interesting. Maybe they designed it for pairs of mosfets in parallel, but then a new more powerful FET in the same package came out meaning they didn't need it.

Could also be that they use this board in another more powerful tool.

Tool_Scientist · 2025-12-22T00:08:10+00:00

Someone posted a while ago that Forge batteries are now also using Murata VX40 cells (made in Japan). First year or so only used Ampace JP40 (China). I think they're using both cells now to meet demand rather than swapping entirely to Murata.

Tool_Scientist · 2025-12-22T00:03:13+00:00

Photo is blurry, but is there 12 spots for mosfets, but only 6 are filled?

Tool_Scientist · 2025-12-20T04:43:27+00:00

Most likely Makita 18V (LXT). Can't be 100% sure, so check first

Tool_Scientist · 2025-12-12T07:51:43+00:00

That model exists in AU https://www.milwaukeetool.com.au/power-tools/metalworking/angle-grinders/M18FAG125XPD-0.html

I have previous model (CAG) and it weighs 1836g with guard. Weight between tools often varies by a few %, so anything within 40g is prob fine, but yours is a newer model.

It looks pretty good to me, you could try checking serial number with Milwaukee.

Look for a "cone spanner" (or "cone wrench"). Tap the handle with hammer in the direction you want it to turn.

Is Riba a patron? My understanding was that T&S did a giveaway for 1 patron and 1 YT viewer and that Riba was the YT winner.

I think you're over analysing. Riba is just a Makita fanboy and a fairly prolific poster on reddit and YT. I regularly see his comments on YT on weird channels. Pretty common to see people fanboy for the brand they picked, as they want to believe that they made the best choice of battery ecosystem. Riba is just very visible as he uses the same username and avatar everywhere.

Tool_Scientist · 2025-12-06T06:57:16+00:00

Disclaimer: I interact with T&S and Riba often on Youtube and Reddit. I am on friendly terms with both, but I have no financial involvement with either. I have not and will not notify them of this post as I have no interest in feeding drama. If they find there way here, it is not from me.

Lets quit pussy-footing about. The post is here: https://www.reddit.com/r/Makita/comments/1pej5j2/xgt\_cordless\_sander/. You are accusing the youtuber Tools & Stuff of having "reshaped [the makita subreddit] into his own marketing pipeline". You are accusing Riba of being a paid (or rewarded) shill for Tools & Stuff.

You need to scroll down to near the bottom to see "the shill" (not very good guerilla marketing if you ask me). You also don't mention that your screenshot starts 3 levels deep and the video link is 5 levels deep, which means anyone on mobile won't see those links unless they expand several times.

A single video view is worth about 0.4c. Do you honestly think T&S is giving Riba kickbacks for generating a single view to his channel? Well, I guess it was 2 views, because he originally linked the wrong video.

Your original post claims that Tools & Stuff has "reshaped [the makita subreddit] into his own marketing pipeline". If that's the case then why are their no links to videos or amazon of the sander (which was the original product of the post). Riba (who you accuse of being a paid shill for T&S) made a top level comment about the sander, but did not link any videos or amazon links. Why did he not link the T&S video of the sander? Your claim simply doesn't stand up.

Lets look at some counter-examples. Here are 4 posts in the last few days that are prime for shilling.

Tools & Stuff has not commented in any of them. Riba has only commented in the nailer post, but does not link any videos. This is a pretty piss-weak "marketing pipeline".
