Rumor has it he used the money he saved to buy a new tip for the soldering iron. Good video.

If you are going to solder wire to a nickel strip piece, I’ve found it’s best for me to do so before I spot weld it to the battery, that way I’m not having to heat battery at all along with the strip.

Aggh! Its such a pain to get the cells out of these holders! They now use lots of glue to hold them in. I had to take a pack apart recently as It took a bath and wanted to prevent them from rusting. Had to cut the case to get them out. Thankfully managed to save the pack.

Los pines grandes es positivo y negativo. Y los 3 pines pequeños para que sirven??

What you could’ve done to avoid forcing it in there is you could’ve tacked the batteries inside the holder that way they could be in perfect place

I'd appreciate it if you could share the link where you got the cells from. Thank you

Could you do a video on installing a balancer on a m12 battery? Your videos on the m18 helped me fixed my batteries. But on the m12 ( specifically 6.0mah) i have trouble finding where to solder the balancer...thanks in advance

I wish you could have somehow shown the performance difference between the two.

Thats awesome wish I had tools to do this to mine

My battery!!!Thanks mate.

Good upgrade, can i use the same driver like a bms for a different 12v battery pack?

You didn’t check the cells initially to ensure they’re balanced before welding them together??

Спасибо за видео!

Oh ineed to see if you have a diy of that tack welser

Was about to say first battery picture was bad... if thats what actually comes in it. Makes me wonder for the drill/impact/hackzall will all push 30+ amps.

Nice job

Def upgrading my dead 6ah packs

BOM DIA SOU DO BRASIL COMO COMSIGO O ESQUEMA DO CAREGADOR M12 DA MILWAUKEE

Is the PCB the same between the 1.4ah and 3.0ah batteries? Nothing limits the new batteries from the higher discharge rate?

i want to check my battery because I had a two led turn on this problem is the battery o charg

I want to know how to make that mini spot welder.

So the temp sensor is on the pcb...? On my bosch 12v pack, there is a small probe going down between the cells, and no balancing wires (don't know if the cells themselves have a voltage cutoff).

Do you know what gauge wire are the main leads? Bought a kit off eBay for diy, but the leads are 18AWG, not sure if they can handle the high current output.

Buen video

Great instructional video. However, I'm a bit perplexed bcuz when you tested for the voltage, it read: 10.92v.., isn't this supposed to read: 12v..?

Now do a 21700 cell 6 AMP battery for the M12 FUEL

Am I the only one without a battery terminal spot welding machine ?

Well done... I am looking for the best bms battery 48v 13s 22a what you advise me Thank you very much

Hi so I did a rebuild on one of Milwaukees M18 12.0HD batteries because it up and quit working and wasnt even that old. It was just dead and when I went to recharged it it was flashing green and red on the charger. So I ordered 15 new samsung battery cells, same as the ones that where in their, then went to town spot welding new tabs on and putting everything back together. Now a couple connections came off of the cercuit board so I soldered them back on. Once everything was put back together I pressed the battery guage button and nothing lit up. I put it on the charger and the green light lit up and said it was fully charged. Now heres the thing I dont get, I plugged it into a tool and it lights up all the indicators but wont run the tool. I tested everything with a volt meter and the cells are each saying 3.441 consistently, and the battery pack itself is reading 17.22 volts. Im stumped. Can you please help me?

Very nice. Thank you.

how did you make your welder

Why did you put kapton tape around the batteries' top and bottom?

Can I do this without a spot welder

and where can we buy the welding machine,not everyone has one at home,and add the cost of long strip of nickel strip that you only have to use 2 inch of it,roll of heat resistance tape that you only used a foot of it,and those gaskets,where is the saving? don't forget the batteries too why don't you put the link for each one so can find out how much it cost?

Beautiful

How do you make an m12 1.5 amp into 3 amp. Special batteries?

Are these considered 3s?

Wouldn't more than doubling the current halve the life expectancy?

If your charger is flashing green and red, try unplugging it. Obvious, but it wasn't the first thing I tried, but it was the last. The Milwaukee Fuel system is more complex than dumb chargers.

The information on the screen is too small to read where you get them from

❤

Ryobi or someone needs to make a battery powered welder thingy he uses here. Ide buy one.

There is no way that you worked that hard to put the repaired cells into the case before TESTING the module on the bench. Seriously?

Wish you went slower. I'm building one from scratch w/o the original bat but a kit from alie with no instructions. I used legit new Samsung inr18650-25r cells from 18650 battery store

Too bad he won't be able to get those out to replace them again lol

Milwaukee vs Sony VTC auto Best

Sony 18650 VTC6 is a great choice 👍

Yeah, that's never coming out again! You should take some of the money you saved on not buying a new battery and invest in a new soldering iron. That has to be the worst looking iron I have ever seen in my life.

...after watching this video I decide buy a new battery. your video is great but it's not my cup of tea.

good video. Turn the sound off and you won't go crazy listening to repetitive music over and over and over and over. Would have been nice to see at the end the charger actually turn the light green once fully charged or does it not ever turn green since this is an altered device now. It would be helpful to know that.

And this is why these batteries are so expensive, even if they are made in China using slave labor and they are...those uighurs in the concentration camps in China are making these ... imagine the costs if they had to pay honest labor

No thanks I'll just buy a new one

This is a modification failure, only 10.6V after replacing the batteries, but the tool gauge shows only two bar full and charger refuses to charge it up. The circuit broad has protection to prevent you use higher ampere batteries. Let's buy the knock off batteries rather than put high quality lithium batteries into the old shell. Not worthy at all.

Can you fix schematics for 6 Ah battery, the one I have found at sellers site are wrong? i.ebayimg.com/images/g/-OUAAOSwERdgSZW~/s-l1600.jpg
