You need to test with high amp tool like the 90° die grinder even with a 6.0 the thing alway cut out and drain battery like no other Or try the circular saw and chainsaw it's where the new battery will shine

do you think it could be a tolerance and or wear problem from factory to factory

@@legros731 The 90" die grinder isn't particularly high current draw per second in my experience, just weak.

The comment about the imitation battery having a dodgy BMS is incorrect, the M12 BMS is located in the tool. The battery packs themselves contain no active circuitry, and any extra performance eeked out of a tool is due to lower internal cell resistance.

Hey what is the website you used to buy the individual Samsung lithium batteries?

Yeah that only seems to happen when the shell breaks

When I first got my M12 ratchet I had troubles with the battery falling out I even had tape across it to make sure it would not do that again and then I switched to an aftermarket battery I've never had one fall out since

Battery’s and good need to break in with around a week or 2 of constant use it will be a lot smoother

To me that sounds like you're keeping the batteries cool. ABS is pretty soft when barely warm (below boiling point). Try leaving a pack sit in the sun for a few hours, then test that latch.

Same, Ive had issues getting them out when they are brand new but I've never had one fall out and my m12 rattle gun is probably my most used tool.

What cells are you using and how u fit 9 cells? You have links? Thanks.

I did the same. There are some bad ass 18650s out there. The beefiest being the Samsung 20S, as used in dewalt flexvolt.

You hve me interested now

Do you guys have links? Curoius to find out about the battery “building”

@@vincentrodrigues7533 You just buy an empty battery shell off ebay or aliexpress, and solder or spot weld bars to the cells, and assemble into the shell.

This was my thought, one thing i noticed from going from 18650 6.0 batteries to smaller 2170 4.0 batteries is that i get more peak power out of the smaller 2170 pack but the larger 6.0 pack will last longer for light jobs (less for heavy jobs, as it works harder/longer to do the same work)

Same i bought a 2.5 to keep things nice and slim, lightweight on my fuel screwdriver amd cut off tool!

I was thinking the same thing. I purchased the 2.5 High Output and noticed absolutely no difference. I'll save my money & stick with the XC Batteries. I have tons of milwaukee tools but they seem to be going in a different with their recent issue with their high torque half inch impact wrench (Rigid is also suing Milwaukee) Most of the high torque impact wrenches that came out recently are all stronger than Milwaukee's 2760-20 gun. However, the 2760-20 is extremely reliable & durable until recently.

@@lowellgelin2063 ridged is suing its sister company

@@lowellgelin2063 seems a bit far fetched that Milwaukee would be getting sued by its own company

i looked it up, and there's no reasons i could find not to other than maybe balancing. if cells are discharging at different rates like a 21700 with 5000mah would compared to a 18650 with 3000mah, their voltage drop would happen at different times and stress each other out. im not an engineer though so maybe im wrong and it should work perfectly

I'd bet the contacts are the next limit , if not the main limit. Lots of tests on RC cars/boats indicate their little prongs are too small for 40A+.

He's tested dozens of different tools with dozens of batteries. The increase from HIgh Output batteries can be viewed across the board. This is the first time high output batteries are producing less power. A prime example would be the impact drivers, drills and impact wrenches all performing better with the High Output CP3.0Ah battery, over the XC 5.0Ah battery. The difference being the 21700 cells. In this case, they didn't increase the cell size and that's why we have these results. You have a battery marked "HO" failing to produce power and a generic monstrosity that was built in a basement that is producing more power. Why? Because of the bigger batteries. It's like he said, but it remains to be seen if it's true or not yet. It's possible that the battery can send more power to tools like the circular saw, maybe the rotary hammer? But typically, with every single tool ever tested on this channel, there is an increase with HO batteries, not a decrease. That's including impact wrenches and drivers. So why now would we see a decrease or a non increase all of the sudden, with the same exact drills. Impacts. It doesn't follow suit with what we've seen and experienced with batteries and tools so far. The flop here, is that the batteries used, with their lower capacity only have the ability to match the 6.0Ah or beat it out slightly. Is it a better battery? Sure. It has a lower capacity and it produces the same power, if not slightly more than the 6.0Ah. Will all the guys who are purchasing 3 to 5 of these batteries see any benefit over the Six 6.0Ah's that they already own? I highly doubt it. All they did was waste money. People have been posting pictures of their 5.0Ah HOs arriving in the mail on Reddit non stop. Some of these dudes already had some 15+ M12 batteries. Just added another 5+... and for what? A battery that can MAYBE draw more power from 1 or 2 tools that 80% of users might not ever use, or don't own those tools at all.

Time to start rewinding power tool motors with larger wire? :^D

@@SixSnax Well there's the benefit of lighter weight... but unless you're a geriatric I guess that doesn't matter much. The cells themselves are also higher quality so they should handle more charge cycles. I'm also left curious about their comparative performance in hot and cold weather. Regardless yeah it's just a little better all around, and the case is the only thing leaping forward. I'm much more impressed with Flex and Dewalt with the Lithium stacks.

@@hydrocarbon8272 maybe but we are talking about very short bursts of current.

Good point, any tool that can "bog" down will benefit more from a HO

Just to clarify with brushless motors in RC cars you increase voltage when you want to increase rpm, the matco 16v is actually 4 18650 (though it looks like it's was designed to have 5) in series as Opposed to the Milwaukees 3, so about a 30 percent increase in voltage

the current hd promotion has a 2 pack of 6.0 x.c batts with a free tool , so if you return. the to the 2 pack of xc 6.0 batteries costs about 100 bucks

I saw the XC3.0/6.0 battery only combo at my local HD (in Hawaii) at $97. I was really tempted but I don’t currently need any batteries. That price almost got me to bite lol

That’s pretty damn impressive, thanks for the info.

Huh. I got a Rustler VXL, might have to look into this :)

@@johncoops6897 only sometimes they run much nicer in the snow. $20 is a lot better than the $200 for the traxxas batteries, plus the $100 dollar charger.

I was thinking this the whole time. Could easily put a 4AH pouch in the small, 3 cell triangle battery case...

But then you don't have the cells. In the handle. It's not a good idea. To mix diffent cell types so you if you went pouch cells you would have a much lower capacity.

@@randybobandy9828 no mixing, only pouch type is what we were thinking about. Pouch batteries offer more energy density than cylindrical cells too.

Glass fiber.

Yep, it will also yield more capacity under load. My 20S filled CP2.0 puts put slightly more current than an xc6.0 but lasts about the same as a CP3.0 under load, just without bogging down.

@@procrastinator1842 5.0 didn't yield any real capacity gains over the 4.0 (cuts per Ah, with the M12 circular saw) at Milwaukee's own pipeline event. It was 46.8 (5.0) vs 46.6 (4.0). It would likely show some gains over the 6.0 considering the sustained load of a circular saw, but Milwaukee still chose to not market against the 6.0 for a reason, because it would've put a damper on the marketing hype. As we basically saw in this video. CP 3.0 is the real loser vs CP 2.0/2.5, with the 2.5 being the most promising considering you need all the amps you can get when you have a CP-style pack with a 1P array of cells. But the 4.0/5.0/6.0 are firmly into the land of diminishing returns at this point. And there's not much sense in spending $120 on a 5.0 when 6.0s are so easily had for $55 with Home Depot hacks right now. The real improvement should be with the battery casement/tabs. But why do we need entirely new SKUs centered around marketing hype to address one of the M12 platform's biggest flaws? These types of improvements need to be made across the board. And as long as the 2.0/4.0 are the most commonly shipped batteries in kits it's always going to be a rather large problem for the end user. Absolutely bone-headed move on Milwaukee's part if they don't eventually make any updates there, and it's probably a safe bet they won't do anything until 2.5/5.0 sales fall off.

My m18 compact impact is also a slouch for lugnuts... Not sure why. I have lugnuts at 77ft lbs that it wouldn't remove. Pathetic..had to use my high torque which was way too much for 78ft lbs.

@@BrandonContracting I ended up grabbing the M18 mid torque and it’s a beast. Has speed settings too, which would help in those situations. Highly recommend the 2962. It’s on Amazon for 157 bare right now.

I built a custom 8.4Ah DeWalt pack out of Molicel P42As, fantastic cells for sure.

Ya those molicel are a beast on capacity and output power. Top cell for electric skateboards.

How do you build your own battery packs for power tools?

@@tstrenuous10 I’d guess you reverse engineer it and rebuild it with the superior parts if you have the right tools

I'll look into that my stubby is noticeably more powerful with the 2.5 then the 3.0 cp
