I rewrote this and deleted the old posts 1. Vacuum will not operate, and battery pack will not charge (it was having less of a charge over time). 2. Bench test of battery: all cells were over 4V, the output of the pack was over 18V but disappears when a small load was applied. 3. Changed the two mosfets. Vacuum still would not operate. 4. Watched the video and performed the circuit board short on 1-2 and 1-5 pins. 5. The pack immediately began discharging the batteries through the 750 ohm resistor R20 (got real hot). Someone else commented on the same thing. Look at the board and find the (3) resistors each marked 750. It is the smaller one out of line with the other two. Don't put your finger on it. 6. Put it outside until next day. Batteries stopped discharging at 2.75V on all cells so the discharge protection is still working. The resistor looks ok. Still will not charge, just flashes. Performed the shorting reset again with the batteries discharged. Put a charge back in each battery individually and they still began to discharge again through 750ohm resistor. I put it in the vacuum and it ran a few seconds so I think a new battery will fix the issue. 7. New battery arrived ($37 on Aliexpress) and it works great again. I guess my old pack was just too far gone. If you're reading this, I hope the shorting method works on yours. The price of these vacuums has only gone up and it's still worth buying a new pack to keep it going. Don't forget to pull out that piece of foam at the top of the dust cannister and wash it out and use a long pair of hemostats (try Harbor Freight) and pull the junk out of the bottom opening. It always works like new again after that. Cheers.

Do you have an idea of unscrewing b012 battery for the hoover h100? Thanks

Lol you shorted every pin! I got what you're saying but i thought it was funny to watch as you list numbers, but i think you meant don't short anything else besides those 5 program pins

So did anyone get any further with their onepwr battery? I have lights 1 and 3 on. I took the battery apart all the 18650 cells are above 3.2v. I can do this reset on pins 1 and 3 and all 5 lights come up and then go off. Still no different though.

im confused, you put on a rubber (no pun intended) , did not do the full calibration, and then the error went away?????

Be Careful, I shorted 1-2 and 1-5, then a chip on the board became extremly hot and will not cool down, and the battery will not even work in the vacuum now even with 18v since I manually charged it before shorting the test pins. This did not work for me and now battery is useless.

I have one and it's similar but I like to say it's like a train chugging along.

thanks 👍🙏

What about the battery that has 10 cells like mine !

Newbie needs help. On voltmeter between pins 1&2 and between pins 1&5 there are 5 volts before shorting and still 5 volts after shorting. I'm certain that I shorted (tried several times). Is voltage after shorting supposed to be a different than 5volts?

Thank you so much for the video it’s really helpful.

My 1 and 5 showed 0.3 volts so I hope this works

Sorry no help for me. My sticks are centered but I still can't do the calibration, I can move left stick in the box chasing the blue circle but thats all I can do and I can't click "next" to go right stick.

TALK!!!!!!!!!!!!!!!!! No speaka English?🤣😂

could be due to really high rpm of the disk spinning so yeah also another reason could be a loose bearing (idk much about hdds tbh)

How do you short the board? It looks like you are using your turned off multimeter probes on P1 and P5, and then a 3rd thing is quickly touching 1 of the probes. What is that? Great video thanks!

Excellent video thank you

Well I was on the same situation 20 v lithium life and I end up buying 2 more batteries an after a few months of use same problem, but came across to this video and I give a try an honestly works for every single one Thank you for the video 😁

The annoying constant beeping is a sign of a really bad programmer... who but an idiot would put a constant alarm on that can't be silenced other than with a hammer.

Anyone know how to do this on a onepwr battery, charger is coming up with a fault All cells checked and voltage is 3.7 on all of them. Is this a counter issue. No idea how to reset counter.

I will buy this Vick's Humidifier very soon. I appreciate your video. Your edit of the video is so matching the product. This Vick's Humidifier is easy to use, friendly, enjoyable, and most importantly - EFFECTIVE. Great video. Loved it. Also, I live in Canada & I really need this for the cold Canadian Winter air. You already knowwwwwww!

what screws weere in the cover plate? I tried the torx bits that I have but nothing fits. It's not metric or regular hex or phillips.

how did you set the volt meter? was the charger plugged in?

can i plug in my vicks in to 220?

In case you wondered why the landfills and the planet are filled with hazardous chemical waste - this is why. Pieces of shit that think up ideas to making battery packs refuse to charge after so many uses. That's even worse than fucking HP with their printer ink.

Worked perfectly. I just taped wires to a regular small battery charger to get some charge in, taping them to the first set of side terminals, then second, then third until they all measured some charge. Also shorted 1&2 and 1&5 pins on the board per the other video to reset the counter. Thanks.

Si se lo desenchufa y se lo vuelve a enchufar, ¿Sigue tirando vapor?

HOW MAKE THİS WİNDOWS ?

Hello can i use the the vicks vaposteam with this?

Thank you! This actually worked!!

Thank you!

Thank you!

The battery on my Vax has a charging board almost identical to yours. The battery measures fully charged but the output is 10v with no current capability. Tried shorting the pins suggested but no change. Have you any ideas?

I wonder if this would work on our 21.6 V Li-Ion battery pack for an older Hoover Cruise ultra lite cordless vacuum cleaner? We bought it used and it seemed to work pretty well for the first few times and then suddenly it started to shut off after about 5 or so seconds of use. I've tried charging the batteries twice and it still shuts off.

This is the exact one I have in my room doesn’t it just sound very peaceful and soothing it’s a very good humidifier that I highly recommend And also it doesn’t prevent you from sleeping you can put in a lavender palette because lavender smells good and also it doesn’t burn your ears while you’re trying to sleep

Where is the review!???

LOL

Got a battery for my vax 20v . Charged for 10 seconds then stopped . Just reset it as the video shows ,now charging .. Worked for Me ,cheers mate 👍 you tube great for fixing things

i have done but still same issue appears

What model and make is that charger please

Saludos. Podtias dar mas detalles pliss

Thank you, the instructions in the box make it more complicated then it is.

Title should be "unpacking and turn on" because video is missing the "review" part.

Hi, I got one of these vacuums and I don't have a battery or a charger. But I have some other battery packs that I can use to test it. I was seeing in the video that instead of giving the full 18v from the terminals, it splits them, left terminal around 8v middle ground and right 8v, is that correct? I don't want to send full 18v from a drill battery and burn it up. I'm guessing for low it uses one sides 8v and high uses both together? Thanks for any input!

At first I was put off that you were typing your dialogue rather than speaking it, but then I realised with the incessant beeping from the controller, if you were speaking the instructions I wouldn't have been able to hear what you were saying anyway :-P Oh.. and top tip, don't turn on or fly your drone with the gimbal guard on, the motors are going to be constantly fighting to move as you moved he drone but cant because they are fixed in place by the guard.

Thanks

This VUL520 humidifier nearly killed me having leaked onto it's own electronics. I had it for a year before it went out with a huge flash and bang in the middle of the night. It is impossible to clean. Produces little vapour. And it is deadly dangerous.

Thanks

Let battery drain it will off, then hold back-up and select button, while connect it to a charger, keep hold button till it shown update
