First of all, take care of yourself and keep hope. Now as for the first battery pack, there are a few suggestions. Always read (measure voltages) of each of the batterie cells, especially when you had the control board removed. That way any suspect cell can be identified before sealing it back up. Secondly, when spot welding tabs, you can always put one lead on the tab to be welded and the other on the battery plate, That will work very well and you can Do that multiple times for more contact area. AND you can also use some activated flux and sold those tabs as well. Usually scrape the tabs, apply the paste flux and solder away... Just some helpful ideas. As for the battery ot charging. They have to be pretty close to the higher voltage level before they will charge. Use a good battery and jump to the discharged battery to get the voltage up and than try charging. Have to trick the chargers sometimes. Thumbs Up and take care of yourself first and foremost!

Praying for you!! STAY STRONG!!

keep step friend. sorry for the sickness. love to watch you!

[@hugegamer5988]

Lithium batteries charge almost exactly the same as lead acid, a constant current constant voltage source is all you need. Set the voltage to be the maximum (often 4.2V/cell) and the current to be 1/2C (2 hour charge rate). For batteries like this you can probably do a 3C rate or 20 min charge rate. If you want to, you can even use the temperature probe wire(s) on the pack to make sure it’s within temperature or use your own thermometer. It’s also a good idea to rebalance these cells, either with a balancer or by slow charging each cell individually.

[@emmettturner9452]

The DeWALT charger is saying “charged” because one bank of cells is full at 4.2v and it refuses to overcharge those just to bring the rest of the pack voltage up. The reasons the pack is at 14.7v instead of ~21v is because… 1) a bank of cells has internally shorted (0v) and… 2) the rest are slightly out of balance. 15v is where the last capacity LED cuts off. The fix is to replace the two bad cells and bring each bank of cells up to 4.1x volts with a generic smart charger. I use alligator clips and a BT-C3400 but I also found a Nitecore New i4 at a thrift store.

[@ryanlawler2006]

This guy is an absolute legend and insane inspiration to me and I'm sure many others as well, much love and respect for you man. Keep up these amazing videos and keep doing what your doing because like I said you have touched the hearts of so many people and have been so inspirational to hundreds of not thousands of people who watch your channel. Nothing but love and respect for you.

[@bobrayme9983]

Well said! 😊

[@GGigabiteM]

I wish you luck in your cancer fight. My dad was diagnosed with stage 4 prostate cancer in January and it's been an extremely difficult road. He's been on hormone and chemo therapy, but hasn't lost any of his hair yet. Hopefully you'll get lucky and keep some or all of yours.

[@Allky]

I really enjoyed that video. I also have a bunch of power tools and batteries laying around that have broken over the years.. I'll get around to fixing them eventually! Seeing videos like this warms my heart as you are making a valiant attempt at keeping these things from going to the landfill. And they're expensive!! Who wants to throw away a $40-80 battery if there is a chance it could be fixed? Not me! Keep it up, and praying for you as always!

[@jaredoocobong2000]

I casually watch your videos so I had no idea he was going through it. Congratulations on the good news.

[@jonathanhoffmansanchez2723]

Wish you the best. Haven’t been watching your videos for too long but you seem like a good person to watch and learn from

Rooting for you, sir! Love the content!

[@aurthorthing7403]

You may not want to talk about it but I do.... It is good to hear you are in remission. Cancer sucks!!! I really do hope you win the battles and the war.

[@DracoMcGuyver]

Steve, I always measure voltage across each cell in order to find defective cells. Usually one is defective.

[@bridlingtonrcbashers9230]

Love your videos. Hope you have a speedy recovery

[@acehart2]

yes bring on the power tools, broken is best. big hugs your awesome

[@Knobcreek12]

One tip on Milwaukee batteries is they do have a low voltage safety that prevents the charger from trying to charge the battery if the voltage is too low and it will also show the red green flash. I have found if I hook it up to a power supply at 18v at around be 100-500mA, usually start with low amps and raise it a little as the voltage climbs. But once it gets to around 15v the charger will recognize the battery and charge it. Gotten dozens of free “dead” batteries that have work for years now.

[@uriahpolite1594]

You look fully healed so pumped for the rest of your journey on KZbin

[@richardcarter1590]

Praying for you bratha stay strong 🙏🏼🙏🏼🙏🏼

[@asusreviews]

I've rebuilt 100's of power tool packs. One welding tip I'll mention, is that to get more weld penetration put one probe on one tab and one on the other, this forces much stronger welds that are not possible with both probes on the same tab. The liquid damage ones are tough especially if its a full featured BMS board. I usually don't touch them if I see corrosion on a BMS board. But I've removed and successfully rebuilt a lot of packs with cells that were a bit rusted. I carefully drill out the spot welds on thicker tabs. You have to be extremely careful because you obviously don't want to drill into the steel cell can itself. But I've drilled out 10's of thousands of spot welds without an issue, just have to be careful and use good sharp 1/8" bits.

[@MrBrymstond]

I'm truly sorry to hear that you have cancer. I've had it in the past. Mycosis Fungoides Which was a bad reaction with proton pump inhibitors and aches 2 blockers from stomach medication like prevacid. and I have Amyloidosis also. Most of the cancers I've had were caused by a medication eruption from medicine, so be careful. God bless you and I wish you the best of luck.

[@bobrayme9983]

What size wires do you suggest for an xbox series s hdmi trace repair? Got one off of ebay and someone didn't heat up the lead free enough before they pulled it seems lol. Got it for a good price.. but I got some 20awg enamel wire.. and it's giant.. have some 40 coming. Think that would be small enough? And I'm so glad to read that it went into remission! You've been my number one Influence/motivation to continue learning how to repair stuff! Thank you for all the knowledge you've passed on to all of us. You're pcb saint! Hope for many more years for you and your family!

[@TronicsFixLongs]

40AWG wire should be small enough. I have used various sizes and one of them is 38AWG so 40 would be close enough. And thank you for the kind words!

[@Benjiizus]

Congrats on remission 🎉

[@DougNoOnions]

I really want you to make a full recovery

[@emmettturner9452]

Measure across the cells, not just the battery pack. You can easily identify a bad cell or a charge balance issue this way. You can then clip a generic cell charger to a cell or bank of parallel cells to charge them when the pack charger doesn’t work. Often, bringing each individual cell/bank back over 3v will get the original charger to take over. If that doesn’t get them all to 4v (full), use the generic charger to top off any cells/banks that are too low.

[@emmettturner9452]

I use BT-C3400 with some alligator clips.

[@TOTKHub]

Get better brother

[@frankc5615]

Red green red green means battery is not good. Red means charging and full green means full charge.. Hope that helps

[@billykulim5202]

whenever i recieved a second hand batttery like this, i always test each cell capacity and then reasembble it, always case like this 1 or 2 cells will be bad

You said you use Dewalt all the time while soldiering the small light board back on and then said I'm not sure how Milwaukee charging lites work while still working on the Dewalt battery pack.

[@TronicsFixLongs]

Haha good catch. I did accidentally say that

[@riccardomarinoni6733]

I suggest to buy a good spot welder like glitter 801d or kweld they are awesome

[@esqueue]

I found battery pack that I couldn't repair. The Dison 5S1P batteries can't be repaired once they start blinking red. I had one with aging cells and when I took it apart and replaced the cells, I made the mistake of not connecting one of the middle voltage leads. This caused a blinking red light. After repairing the issue, I found out that once the BMS blinks red, there is nothing that you can do with normally available tools to reset the BMS. I'm sure that they have a way of resetting their BMS but I can't. I ended up using the batteries with a Amazon failed pack with fake ratings (literally 100% of Amazon packs) and swap out their crap cells for the ones I was to use in the OG Dison pack. Vacuum still working a few years later.

[@theone2be33]

Hi Steve. Should've showed if battery was OEM or knockoff

Hey Steve I Googled the alternating red green, try pushing the battery in further with a little more force. I can't post a link otherwise I'd share the youtube video on this issue.

[@MinscShip]

the first battery, looks like it was drop. i have repair a couple of them, all been drop from 10meter plus. the dewalt you need to reset it for it charge prolly, by resetting you need to drain it 100%

[@waleed9128]

Do you have the link to the battery spot welder?

[@nomanisrar4311]

U need to activate the BMS through the software nd also need calibration of the batterie just like a laptop battery

[@rcook0001]

Steve, Be strong porta cath are the best method, I just hope you are not getting Folfox. If you start to lose feeling in your fingertips let your oncologist know. They will reduce the dosage, so don't end up like me losing the feelings in your fingers. I went from able to micro solder Iphones to now even a PS1 is hard to fix.

[@bam6972]

the dewalt battery prolly has a dead cell. test each cell for 3.5v and up is good find the one that isnt contributing and replace it with a known good cell and walla.

[@DracoMcGuyver]

Shouldn't that red wire joint be covered with heat shrink?

[@armandine2]

SOIC-8 pins grouped 4, 3, 1 = mosfet?

The area to be spot welded needs to be supported underneath.

@@galvanizedgnome I rather not buy a portable drill because I barely do any drilling. 1) I don't want a powerful battery in the house. 2) My last drill's battery died because was barely being used. Our old, corded drills from mom and pop are still working since the 80s.
