Nice work, I would recommend a spot welder tho. Not great getting the cells that hot, also not great to install them fully charged if you short circuit, It will be much more violet them one charged to storage, around 3.8v. working on one now.
it could meen that only one set of segments just discharged more than others. You could have fix that just by charging each set of segments separately on some of the cheap battery tester you showed on the start of the video. Pull two wires + and - and connect to battery. After you finish charging them all up, just reasemble battery (without disconnecting pins) and put it on charger, and you fixed it.
So it charges on all m18 chargers like normal? I mean if the the pack is already bad you really got nothing to lose. Hell ive been under the impression that the bms board would erase its firmware if it lost power. Good stuff dude. Subscription added Thank you for recording this.
Or sometimes need to just reset it. It can overtemp and pop the built in thermal fuse on the positive lead. Stick a screwdriver in there and push it down. Charge and try it again.
Destroy I'm still using these batteries today. I'm Definatly no expert on electronics. but I feel like this is a common thing that happens and I was able to get a like new battery on the cheep with the knowledge I do have. Limited but enough to get the job done
Its not ideal in and out let cool in n out let cool. Built many diy packs using these cells for quadcopters replaced cells from a m18 battery. While not losing any capacity no damage. You gotta be familiar with soldering before attempting this dangerous procedure. Need to set up my spot welder as its much safer.
I know heat is bad. So I use low melting point solder and I do it fast. Every single battery I've rebuilt I'm still using to this day. But mabie one day I'll invest in a spot welder.
@@WorkingClassKnowledge I’ve worked with you guys on a couple jobs. And I live in Charlestown and seen you around. Small world I search Milwaukee battery storage and your videos came up. I started watching it and was like I know this guy..too funny small world. Best of luck with everything..
you should not be telling people to solder these cells instead of spot welding. you have earned a dislike from me and I'll never be subbing to your channel. I really hope nobody follows this dangerous advice.

Kyle, any suggestions on a good spot welder for this kind of thing?
@@shadetreewannabe k weld spot welder with supercaps
i am surprised to see BMS still work
i couldn’t get it to wake up when i swap good working to a broke one 9Ah version
Very useful info!! 👏👏👏🙏🏻🙏🏻🙏🏻🙌🙌

soldering instead of spot welding will likely damage the battery
Umm you could just replace the bad cell. They last a really long time so full rebuild is never worth it. Unless you have several bad cells.
Or sometimes need to just reset it. It can overtemp and pop the built in thermal fuse on the positive lead. Stick a screwdriver in there and push it down. Charge and try it again.
I grab the batteries people put in the bins at home Depot and rebuild them if I can. A lot of the time people just don't fully charge them
How do you get them to let you do that? They have told me no before when I had asked
you didnt even check the induvidual voltage before destroying? it could be a ballance issue

You had your torque driver set to number three the highest torque level, better to click it to number one lowest torque setting
Soldering these batteries will permanently damaged and or reduce the capacity they should always be spot welled.

Spot weld not solder the cells. Not good to heat the batteries.

PLEASE DON'T solder directly to battery cells.
Not only is it very likely you'll get one too hot but it can also explode in your face.
Dude you look familiar.. do you work in Charlestown for Sean?? I swear I seen you around.
Yes that is me
Are you one of Sean's Customers? Or did you work with us on a job?

Yeah that's cool yeah def a small world thanks you too.
Thanks great info
Something you should maybe do is wear safety glasses 👓 🥸
Ive never worn safety glasses. got metal in my eye once. I know I should but I don't
@@WorkingClassKnowledge just thought I'd mention it cause you had you face so close to battery pack and earlier you said have an exit plan 🥽
@@Handle4570 yeah they do go nuclear if you short something. that's for sure
