150% More Power : Milwaukee M12 Battery Upgrade!!

[@goodmanshealth]

That success was a lot to ingest but thank goodness you made it easy to digest.

[@Kitearmy]

don't eat batteries

[@nathanvanlieshout7834]

So, you went from a 1.5AH battery to a 2.8AH battery so much better run time. BUT also going from 23A discharge rate to 35A means much more "power output" which would be noticeable, especially on your little saw and other high load tools. I'd say 150% more run time in practice, with around 52% more power output in theory. Very cool to see.

[@ericklein5097]

All depends on the wattage of the saw and if it can use it

[@colonelkfc33]

This stuff will become more and more important as more things go battery powered. Home owmers, small engine repair people, and implement dealers will want to know how to do these types of repairs/replacement especially when the warranty runs out. It will just make battery powered implements even more economical and be able to be used even further into the future.

[@Kitearmy]

Good stuff to know for sure!

[@AppleFanX2]

Very informative! Thanks Andrew!

[@Kitearmy]

Glad you liked it

[@willptech7565]

Nice job. I’ve been building packs for a while now and for you second time, your not that bad lol!

[@lookoutman]

Well done!

[@Kitearmy]

Thanks

[@holeshot1721]

Just get the conversion adapter where you use the regular bigger batteries

[@alexlongpre4527]

Great video, you just showed exactly what I wanted to do but wasn't sure how to go about it. Thanks. Do you have a link to those molicell's

[@MadLadCustoms]

Good info, I've recently bought a knockoff 9ah Makita battery that has less capacity than my 6 year old 5ah from Makita 🤡 Chyna alive and well, but at least I have a good pack to replace the cells and make my own with this method!

[@Kitearmy]

So cool!

[@DarksouIjah]

You should have done the Tim Taylor grunt from Home Improvement. “More power!! Ugh ugh ugh!” Ok yeah, I’m a nerd, don’t judge me.

[@Kitearmy]

I think we are all nerds at heart

[@SouthFLTools]

Great job Andrew! Redemption is definitely yours this time around, congrats!! Was curious to know if you are in the M12 line of tools when it comes to drills and impact drivers. If so, how do you like them? I like the fact that they appear to be compact. Just not sure if they are as good and dependable as the larger 18v or 20v tools.

[@Kitearmy]

I have the M12 for the light stuff and Flex for the heavy duty stuff

[@SouthFLTools]

@@Kitearmy awesome, appreciate the feedback. Flex is definitely a powerful line of tools to invest in and is very attractive right now with their lifetime warranty.

[@Kitearmy]

@@SouthFLTools The quality of the stuff is impecable

[@chrisalbertson5838]

My 12 drills are used for most jobs, I use the heavier M18 for things like circle saws and drilling concrete. But 90% of the time all you need is maybe to predrill a scew holes and drive a screw. Other times M18 is the only option, like my M18 circular saw. With lights M12 units are like powerful flashlights. The M18 are more like worklights for lighting u a room.

[@pointnozzleaway]

I know spotwelding, and I know Lithium batteries.....You Sir 🏆

[@AlAmantea]

Your math is wrong... 25 is 227% of 11. Your success was greater than you thought!

[@DomEdw]

It is wrong but he also said “think” and “give or take” plus the key word “better” meaning the originals total (100%) plus that 150% basically coming to a total of 250% +/- give the man his credit.

[@ironman1518.]

Excellent video great presentation of the proces!! Thank you. Question please> Where do we get the insulators, metal tape and the temperature tape please? TIA!!

[@MGMan37]

Does this bring it in line with the "High Output" official batteries? For instance the 2.5 HO. Curious about building a smaller battery that gets more power out of the gen 2 3/8 stubby impact.

[@themexicanstaringfrogofsou5268]

These molicels are much better than in the high output versions

[@bmfesta2009]

Event training video and really happy to see you were successful this time. So after going through this process I have to ask... Is it that much of a savings to rebuild a pack yourself vs buying a replacement?

[@Kitearmy]

It's a close call with this pack - but the larger the pack the bigger the cost savings would be

[@Thomas-xm5ym]

What’s the song at the beginning?

[@jdao917]

if you have a higher cdr does that mean theres more power that goes into the tool? 35AMP vs 23amps?

[@OptimisticDeer-sn5fn]

Amps mean it lasts longer volts make it go faster

[@cadrake89]

Is this Stevie from the show eastbound and down?

[@Kitearmy]

nailed it

[@jakbain1337]

So you effectively made a 3ah m12 battery pack that's available off the shelf? I'd be interested is seeing how it compares to a genuine 3ah m12 battery. Not negating the information regarding replacing of cells good to know when it comes to fixing damaged packs that's good information! Just feels wrong to compare the results in this way. For lack of a better analogy, my 100L fish tank broke I fixed it and now it's 200L and it now holds twice as much.

[@Kitearmy]

Or you had a 100l fish tank that would not hold water and now it does.

[@jakbain1337]

​@@Kitearmy ​This video doesn't portray that narrative. ​This video has a lot of emphasis on how the modified battery is so much better and how it lasts 150% longer. (Not 150% more power which should be 125% anyway) not that it is now functioning. The results are misleading considering there is already a STOCK 3ah battery. Don't market a repair video as an upgrade video. There is no link to the previous video in the description.

[@Kitearmy]

@@jakbain1337 Glad you loved the video

Where can I buy the batteries?

[@noelnicholls1894]

This is a saver video, just in case. And a great project, though there are many off the shelf options now. Have had the twelve volt Milwaukee system nearly twenty years now and only in the last few years have the batteries started failing. Obviously I’m only an infrequent user. However there’s a lot of options now on Amazon for upgraded batteries with greater amp hours than the original. Got two and they far exceed the originals, and were far less expensive than the OEM options. But that work table and mini welder just looked like fantastically useful for building small stuff.

[@Harvz78]

@@noelnicholls1894 Are you talking about the Chinese knockoff batteries on Amazon and eBay that is falsely rated 3.0ah which is actually just 1.8ah?

[@noelnicholls1894]

@@Harvz78 It’s a crapshoot

[@Kitearmy]

@@noelnicholls1894 The helping hands are a must have - I would be careful with the Amazon batteries - they often overstate their specs.

[@GillySqueeze]

150 percent more power than a 1.5 what about 2.0A?

[@haroldneely9253]

👍

[@Kitearmy]

Thanks mate

[@doughartley6789]

Can you get by soldering instead of welding??

[@microfilm1001]

soldering heats up the cell what is not good

[@MarkK01]

I have a couple M12 XC6.0 batteries that won't charge properly any more. I am to much of a chicken S^^T to mess with them lol. I would just sooner buy new ones.

[@davidtran4760]

You need to make sure that all 3 cells are at the same charge level. Otherwise you will not be getting the most out of the cells. Its the same as how you should not mix an old AA alkaline with a new one. The old battery will drain the life out of the new one fast.

[@Kitearmy]

Good point -these were all bought new - not sure if the milwaukee charger balances the batteries

[@brettwalkom948]

Doesn't the chip in the battery Ballance the charge rates

[@Kitearmy]

@@brettwalkom948 yes - but if the cells get out of balance the BMS can handle that

[@MCMinerHQ]

There is absolutely no way that cells discharge rating is true. The amp hours is believable but not at that C rating and especially for that price. You can’t have all three.

[@quintinwhite8653]

Molicels CDR are accurate. They are stronger and better batteries than the batteries milwaukee uses in all of their m12 and m18 batteries

[@saulgoodman2018]

More runtime. Not more power.

[@Kitearmy]

Right!

[@ethandonivan5175]

I wouldn't be surprised if the new better cells have a better time with voltage sag.
