manjit Marwaha: Thank you. That’s the power of video. By the way I put some subtitles for non-Koreans. You know Mr Bong (parasite) said “If you can overcome an 1-inch barrier of subtitles, you can reach so many good videos.”
Yes, this is VERY GOOD video series - you are a good teacher. Your video presentation is excellent so language is not important and the subtitles work great. Thank you for speaking in your own language during the video, rather than adding stupid music and graphics like other channels. I also like the funny jokes and comments in the subtitles... I am in Sydney Australia and I only speak English. There are a lot of Korean people living here but we do not usually hear or read any Asian humour! :-)
Thank you for enjoying the video. By the way, some of subtitle humors in the series may come from RUclips automatic translations. Sometimes they are silly. Please be aware of the possibility.
The subtitles generally worked fine (auto subtitles can be pretty funny sometimes, but Dr Kim chose his words well. Accurate word choice makes for better auto translation subtitles) . Nonetheless, I think Dr Kim's style of explanation could work, even without the subtitles - I didn't notice them until half-way to the end! I also very much appreciate that you do these videos in your first language of Korean. If everything on the internet was in English, we wouldn't learn/exchange anything about other cultures! I picked up where you were saying I think se jeom se bolteu for 3.3v, is that correct? I don't know any Korean, but I got a tiny glimpse of how your language works, which was also interesting. It is very interesting to hear someone go through a thought process in another language. Last year I had to remove a gearbox and clutch from a Fiat at home, and the only decent info I could find (Fiat don't allow workshop manuals) was a RUclips video by a Russian fellow, in Russian with no subtitles. It was kind of fun to be watching him work his way through problems in Russian in his garage in Russia while I worked on the same problems in my own garage in Australia, thinking in English. What an age we live in where we can share these things. Peace to you all and all your countries!
Yes. Indeed we are all connected through RUclips videos in this age. I also got a lot of information from foreign videos. You picked up very closely the Korean ‘sam jeom sam’ bolt for 3.3 V. Sam means three and jeom means dot.
Thank you! This is a brilliant demonstration of how to solve a simple electronic problem, and also of how to change the PCB - even when the terminals differed. Great work. The camera position is excellent and you demonstrate problem solving using pen and paper - this type of video is something many young people should watch to understand how things can easily be tested and fixed (instead of thrown away). Unfortunately, I found this video AFTER buying a new battery for my Dyson. Now I wish I had found this earlier and changed the PCB (every new plastic product we buy contributes to the environmental problems for our grandchildren). In future I will check my battery voltages and try to change the PCB. In fact, I might test the old battery unit, repair it and give it away to someone who needs a new battery. Power to you Dr Kim - you have a another fan! (Me!)
I too bought a replacement circuit board from Aliexpress for £13, 4 days delivery. I took care not to blast it when soldering the old batteries onto it. Just avoid shorting volts (from fully charged cells) to points where they are not appreciated. Worked striaght away. Dyson now as good as new. Well chuffed.
Thank you so much for your video, it was actually an easy and cheap fix compared to buying a new battery. Ordered a BMS from Aliexpress but I fried it with a short (my bad), so ordered a second one and it is fixed now! The hardest parts are to disassemble the battery case and desolder the BMS (a real pain in the back)...
Very good and clean work! I did the same, simply I solder the negative pole at the end, just before closing the box, so I am sure to avoid a short issue during the work.
Thanks to you men, i have finnaly restore my old battery pack with replacing their pcb board that i purchased from China and install it with reffering from your video verry help me out dude😅 after i know it will work after just replacing that lamo Original PCB board dyson🤣.. Now i have a spare battery with a low cost😆. Thanks a lot to you men honestly🤩🥰
Great job, I believe the red light is the result from a dropped battery. The thermistor wire breaks then the firmware bricks itself to red light. The board would be perfect if the firmware is reloaded and thermistor repaired in my opinion. Also you can open the battery in 10 seconds. Put small end in the vise, pull sideways both ways.
Thank you. You may be right. Dyson did not want to disclose how to reset the firmware. The replacement pcb works perfectly last two years. I don’t see any battery life shortened.
Great video.. Right now i just considering to purchase pcb board from china for repair my old battery that same like you blinking red 32 times.. Thanks you for video that now i know its will work after replace pcb board
Thanks for showing how to open the case. My PCB is ok but my batteries are not. I am removing all the battery cells and installing some salvaged 3400 - 3450mah nitecore batteries. I can't even run my vacuum on high at the moment as it will cut out and not go again until it is placed on charge for about 10 seconds.
@@DrKimFixnSolve I have restored my battery with 3400mAh batteries. Had to build a spot welder with a motorcyle relay, copper rod from welder coils, speaker wire and a 3D parts (to hold the electrodes) in order to connect the nickel strips to the batteries. The V6 hasn't sounded this good in quite a while. WAF!
It is programmed obsoletion. My battery said it was empty all the time (flashing blue), measured the 18650 cells and they were all 4.01v. I am certain the board is programmed to stop after x charging cycles. I removed the 18650 cells and use them for something else and they work perfect.
i just bought a multimetre today and measured both battery and the main body .battery was ok 23,5 V . I measured the main body for the first 3 seconds i got the beep sound and it stoped. Can i assume there is a short circuit in main body? But when insert the battery it works with no problem . After 5 mn of working it gives me the red flashing light and stops. Then i remove the battery and press the button to check it , it gives blue light and 23V which means it is ok ? What can the red light result from even though battery and main body works ok?thanks in advance
@@DrKimFixnSolve thank you master for your answer, I opened the motor and there is a tear on one of the cables. you can see the inside of the metal cable. can that cause these problems?
I have not one but two of these dratted batteries. Battery *1 flashes blue (likely different fault) Battery *2 is dead as a brick. Would be interesting to see if swapping the BMS will fix it. In the meantime going to order a spare BMS.
@@DrKimFixnSolve Alas battery *2 was leaking. Only noticed when dismantled, its the cell closest to the back. Fortunately got rid of it but the cells were reading 3.8V.
Thank you for visiting my channel. Regarding the thermistor, it may be buried at the battery, not attached in the BMS. Please check this video ruclips.net/video/GfvOSTppl2g/видео.html and 20:26 in the part. Hope it helpful for your hacks.
I have the same battery problem. Flashing red for a minute maybe then off. When measuring the voltage directly from the positive and negative holes in the battery pack, the multimeter reads near 22.6 volts wich is more than perfect. Its seems they balance and all batteries are charged. BUT, back in the time probsbly BMS Registered low voltage failure flag or just faulty chip of BMS. I'll try to figure out.

This is a summary video of how to fix a Dyson V6 battery with red-light flashing more than 30 times and no charging any more. In this video, I tried to open the battery case without too much scratches, diagnosed the battery problem, purchased a replacement part (a third-party BMS-PCB from China), detached the faulty Dyson OEM PCB, soldered the replacement PCB, and finally reassembled the battery and applied to the Dyson V6 Cordless. The fix was successful and the replacement part works perfectly. I think the Dyson V6 BMS-PCB has some wrong (evil) design, otherwise it should work with any healthy battery cells. Now Dyson should fix it. Added an English subtitle. If you think the video was helpful, please subscribe my channel. *** If you feel it is dangerous, DO NOT OPEN the battery ***
Jon B Good, but be aware that new replacement battery has the same BMS risk. My warranty replacement battery was dead yesterday (red light blinking) after 1 year. Watch my new video.
hi, friend, i am Kristin, we are a professional manufacturer of Dyson replacement battery , V6 / V8 / V10 / DC35B battery are available, any need welcome to contact me , my Whatsapp / Wechat / Skype : + 8618620606852
No idea what's going on but looks interesting. It would be great if you could do a video on how to resolve the battery cutting off on a Dyson DC30 Type B. I have cleaned it etc... it's not the typical issue. The problem appears to be with the battery protection
It would be great if dyson does next party with easy battery replacement option, hard to know why we drop everything when 1 cells going black on all electronics...
On my Dyson V6, the battery flashes red !! but sometimes it kicks off and the led is blue, if I release the trigger, then press it again, it still works well! if I leave it inactive for too long (+/- 30 sec) it flashes red again! and trying a few times it reboots correctly, every time like this i have a hard time knowing if the problem is with the battery (maybe BMS) or if it's the motor. In your opinion?
Dr. Kim Is it possible the BMS (battery management system) has a program to disable charging after a certain number of cycles? In that case one could disconnect the power to the chip and reset it to "zero".
As I know, people have already tried to disconnect the power to the PCB, but it didn't work out (forum.allaboutcircuits.com/threads/bms-reset-ideas-dyson-v8-vacuum.146511/ ). Still we don't know how to reset the locked BMS. There may be a special sequence to reset the BMS, but Dyson won't disclose any information about it.
have a dison dc62 product. It works constantly without pressing the trigger. The transistor on the card above the battery exploded. It is not fully readable 4200ad ???. Anyone have any information?
Sir the bms i bought from aliexpress is a little problematic! It cuts off at 23V and shows 0V. Actually it should cut off at 21,6V but it doesn t so it gives me less run time! What a shame !
Hy i have the blue light blinking problem when I putting it to the charger it starts to charge after few second start to blink on blu I just disassemble the baterry pack al cels are at 4.1 volt Should i take apart the head ? Maybe something is stuck ? When i start the vacum it start for few second and then starts to blink on red
I have no experience about this. Hopefully others could help you in this matter. If I were you, I would replace the bms as I did before. At least you have healthy battery cells. Good luck.
At 05:35 you warn of causing a short circuit when snipping where you say "it's scary" can you please be more specific on how to safely cut off those tips?
Found reason for your comment. In an older video you unknowingly caused a short circuit when your snippers came in contact with a second piece of metal jutting out from the battery pack while you were attempting to do this same process. ruclips.net/video/Y2CsA5T5TPc/видео.html
Sir i just seperated the bms and i will solder the new one from china. You used some copper wires. If i unsolder the original nickel connections as intact, can i put them back in the new bms holes and solder it or i have to cut them on the edge and connect with copper wires like you did?
@@DrKimFixnSolve master Kim one more question: You said i put a lot of solder on the negatif nickel in the battery, i also put average solder not very much like you. Is this a problem? Can battery fail in the long term because of this?
Aber sorry wenn du eh eine neue Batterie bestellst wieso dann noch die Leiterplatte reparieren und ersetzen ...nimm doch einfach die neue Batterie....? Ok vielleicht kostet die Leiterplatte weniger ....aber nur schon die ganze Arbeit und ein Lötgerät braucht es auch ......oder habe ich was falsch interpretiert weil chinesisch verstehe ich eh nicht. Danke aber video war sicher gut.
Thank you for watching! A new Dyson battery may cost ~$100. Replacement battery ~$50 PCB ~$10 or less. Definitely worth to try. Also we can save the resource to protect the world. The video language is Korean from a country of Mr. Bong Jun-Ho ("Parasite") and BTS.
по другому ни как? Это видео для 5 класа, много у а не надо. Без готовой bms , с универсальной, отремонтируете батарею, чтобы в родной корпус все влезло?
You may be right, but without a safety-proved BMS it may be too dangerous to fix a high-voltage battery. I can say that the third-party BMS works fine by now. Good luck.
I would not call this a "repair" video, its just a parts replacement video, in the same way like you would replace the wheel on your car when you have flat tire, you do not actually fix anything just replace the parts and then still have to go to tire fixing shop and they would "plug the hole" in the tire.
drkimfixnsolve.tistory.com/28 Check this out. I purchased a replacement PCB from AliExpress. Now I am working on another with a replacement PCB from Banggood. You can google them.
Hello, I have the same problem with the red light flashing 32 times, after that 1 time green light. Meassured each battery: 3.45-3.51 V on each cell and all together 20.89 V on the connected cells. When pressing the power button, I got 20.07 V on the engine connector. What could be the problem? I left it empty for one weak (forgot charging it) and since then I have this problem. But the cells doesn‘t look damaged since they have all arround 3.5V? Does someone have an idea?
I guess the voltage imbalance may happen during the week. If you can’t charge the battery due to red light flashing, you have to replace the locked BMS PCB.
It's not a wrong design. Dyson circuit could detect battery cell to check the battery is original, if not it will stop working. They just want your money.
Sorry. The full versions (how-to-fix-a-dyson-battery series #1-#5 ruclips.net/p/PLSR_P1uXKtezcG9-4yInUVQcIXHMlnmRk ) are available in my channel. Check it out after subscription.
Stick it in a vice a whack it left or right it whips of in a second ,zero damage. Worst dyson ever invented same as these cars too many safety features causing small issues that would cause any damage stupidest battery pack ever, I will be bypassing the bms because I know my cells are brand new.

Where to buy a BMS-PCB (power protection board) of Dyson V6 battery with red-light flashing by 32 times
Can I use the same process for my dyson v7 motorhead?
Sure if you can find a replacement BMS for V7.
On my Dyson V6, the battery flashes red !! but sometimes it kicks off and the led is blue, if I release the trigger, then press it again, it still works well! if I leave it inactive for too long (+/- 30 sec) it flashes red again! and trying a few times it reboots correctly, every time like this i have a hard time knowing if the problem is with the battery (maybe BMS) or if it's the motor.

Better to replace the battery (or BMS). I have no problem with the new BMS last two+ years.
Is it still current? Or did we find ways to flash the original BMS or something?
I think this is only the way or buy a replacement battery.

Sir the bms i bought from aliexpress is a little problematic! It cuts off at 23V and shows 0V. Actually it should cut off at 21,6V but it doesn t so it gives me less run time! What a shame !
Thank you.
Hy i have the blue light blinking problem when I putting it to the charger it starts to charge after few second start to blink on blu
I just disassemble the baterry pack al cels are at 4.1 volt
Should i take apart the head ? Maybe something is stuck ? When i start the vacum it start for few second and then starts to blink on red
I have no experience about this. Hopefully others could help you in this matter.
If I were you, I would replace the bms as I did before. At least you have healthy battery cells. Good luck.
Before any DIY, call Dyson and get a replacement battery if your warranty is active.
At 05:35 you warn of causing a short circuit when snipping where you say "it's scary" can you please be more specific on how to safely cut off those tips?
Found reason for your comment. In an older video you unknowingly caused a short circuit when your snippers came in contact with a second piece of metal jutting out from the battery pack while you were attempting to do this same process. ruclips.net/video/Y2CsA5T5TPc/видео.html
Exactly. Be careful not to touch two terminals at the same time.
Sir i just seperated the bms and i will solder the new one from china.
You used some copper wires.
If i unsolder the original nickel connections as intact, can i put them back in the new bms holes and solder it or i have to cut them on the edge and connect with copper wires like you did?
If you can use the original nickel wire, it will be better. For me, the hole shape was different so that I had to use the copper wires to connect.
@@DrKimFixnSolve sir you are a great master and sensei😊
@@DrKimFixnSolve master Kim one more question:
You said i put a lot of solder on the negatif nickel in the battery, i also put average solder not very much like you. Is this a problem? Can battery fail in the long term because of this?
@@torukojinnn6331 it may be okay.
@@DrKimFixnSolve thanks
Aber sorry wenn du eh eine neue Batterie bestellst wieso dann noch die Leiterplatte reparieren und ersetzen ...nimm doch einfach die neue Batterie....? Ok vielleicht kostet die Leiterplatte weniger ....aber nur schon die ganze Arbeit und ein Lötgerät braucht es auch ......oder habe ich was falsch interpretiert weil chinesisch verstehe ich eh nicht. Danke aber video war sicher gut.
Thank you for watching! A new Dyson battery may cost ~$100. Replacement battery ~$50 PCB ~$10 or less. Definitely worth to try. Also we can save the resource to protect the world. The video language is Korean from a country of Mr. Bong Jun-Ho ("Parasite") and BTS.
My v5 Dyson has this exact same problem. Two red flashing lights that flash 32 times. Dyson wants $112 to fix it. Have you run across any v5 hacks?
Sorry, I haven’t. It may be similar with a faulty bms. Also you may need to refill the battery if it has been a while.
по другому ни как?
Это видео для 5 класа, много у а не надо. Без готовой bms , с универсальной, отремонтируете батарею, чтобы в родной корпус все влезло?
You may be right, but without a safety-proved BMS it may be too dangerous to fix a high-voltage battery. I can say that the third-party BMS works fine by now. Good luck.
Добрый день. Где можно заказать такую деталь?
drkimfixnsolve.tistory.com/73 Проверьте это.
I would not call this a "repair" video, its just a parts replacement video, in the same way like you would replace the wheel on your car when you have flat tire, you do not actually fix anything just replace the parts and then still have to go to tire fixing shop and they would "plug the hole" in the tire.
Right. Replacement.
Which exact part did you purchase?
drkimfixnsolve.tistory.com/28 Check this out. I purchased a replacement PCB from AliExpress. Now I am working on another with a replacement PCB from Banggood. You can google them.
Got it, look for "battery protection board for Dyson" on Aliexpress. Ordered today.
Hello, I have the same problem with the red light flashing 32 times, after that 1 time green light. Meassured each battery: 3.45-3.51 V on each cell and all together 20.89 V on the connected cells. When pressing the power button, I got 20.07 V on the engine connector.
What could be the problem? I left it empty for one weak (forgot charging it) and since then I have this problem. But the cells doesn‘t look damaged since they have all arround 3.5V?
Does someone have an idea?
I guess the voltage imbalance may happen during the week. If you can’t charge the battery due to red light flashing, you have to replace the locked BMS PCB.
@@DrKimFixnSolve so you think it is simply due to cells being unbalanced?
Khal Khal: Yes, I think so.
@@DrKimFixnSolve so why haven't you tried to balance the cells instead of replacing the bms?
Khal Khal : once the bms is locked, there is no known way yet to reset the bms.
It's not a wrong design. Dyson circuit could detect battery cell to check the battery is original, if not it will stop working. They just want your money.
Thank you for the opinion.
성님 저는 V6 유저인데 배터리가 SV09 인데요, 같은 PCB로 교체해도 될까요?
아 그리고 영상 감사합니다 이해하기 쉽게 찍어주셔서 분해 잘 했습니다 ㅎ
네 되는 걸로 알고 있습니다.
이거 바꿔끼고나니 충전이 안되는데 혹시 원인이 뭘까요?
글쎄요. 제가 한 작업과 꼼꼼히 비교해 보시죠.
You replaced Dyson bms board, not fixing it... It seems like no one can solve the red light issue of Dyson bms board. 😂
Jefferey Jiang You are right. No way to fix the bms. But I DIY-fixed the faulty Dyson battery.
돋보기김선생 Fix n Solve I have the same style Dyson and have the red flashing lights too. Also no charge I bought the battery today so need to replace
There is a way to reset the lock status, no need for so much work to change the BMS. video here: ruclips.net/video/7t9yA3_KUI0/видео.html
Thank you for sharing your solution.
@@DrKimFixnSolve you're welcome!
i also want 3 hands ;-)
ㅋㅋ Hope you have them.
Yes, 3 hands are very useful doing any soldering :-)
dont like the way you skipping the video
Sorry. The full versions (how-to-fix-a-dyson-battery series #1-#5 ruclips.net/p/PLSR_P1uXKtezcG9-4yInUVQcIXHMlnmRk ) are available in my channel. Check it out after subscription.
Stick it in a vice a whack it left or right it whips of in a second ,zero damage. Worst dyson ever invented same as these cars too many safety features causing small issues that would cause any damage stupidest battery pack ever, I will be bypassing the bms because I know my cells are brand new.
Agreed.
