Hello there I have a few urgent quesions. What nominal cell volt is roborock using ? 3.6 x 4 = 14.4v right? wont the ID on the BMS brick itself when you tear down? Does anyone know what max amp The board can handle? Can I use more batteries in paralell? I suppose other BMS boards cant be used when they lack ID/T support
*What nominal cell volt is roborock using ? 3.6 x 4 = 14.4v right? Charged - 4.2 x 4 = 16.8v *wont the ID on the BMS brick itself when you tear down? I haven't that issue. (only blown fuse) *Does anyone know what max amp The board can handle? In my opinion around 5A *Can I use more batteries in paralell? There no room for more batteries if idea is get more capacity use cells with high capacity * I suppose other BMS boards cant be used when they lack ID/T support No idea I've haven't tried .
@@chichovenci I have solved the problem. Before installing the renewed pack, I have tried to charge it by connecting it to my charger. Female connectors has expanded while doing this and when I connect it to robot socket, it didn't sense the battery. I changed the connector and now it is working.
friend, please tell me, does the plastic tube inside the oil filter housing have to stand motionless inside, or is it normal that it is hanging out there?
I just bought a D3. Previous owner just did valve cover gaskets, but I still have what appears to be pretty good leaks on both sides, do you suppose it could be because the rubber washers on the bolts maybe weren't replaced?
My vacuum died again and now i had 2 dead batterys laying around. Saw this and figured i might combine all good cells to make 1 good battery out of 2 dead ones. Was my first real soldering job i ever did but i did it and my vacuum works again. Thank you!
this video is cool i can see everything you doing to the strut assembly however, you don't mention the parts being disassembled. I would greatly appreciate it.
No problem i see that the inner part was the air bag cool. I see that it had a strut rather than a shock absorber, strut bushings, strut boot, upper control arm, the strut cap. All I know in those parts its all integrated. Just was doing a research for the difference. Its for the purpose of extended warranty. they definitely don't cover shocks but they do cover struts. Thanks again for your video sorry it was a while back but informative. Happy holidays!
That's the idea heater starting heating the cabin and engine and stops after the interval you choose 15, 30 .... min. It is not necessary to be around the car (car can be locked on the parking and process starting according to timers)
Buenas tardes! Alguien sabe porque puede ser que mi vacuum comenzó a funcionar lenta de un día al otro. La limpié toda, pero sigue lenta, hace unos días atrás iba mucho más rápido haciendo su limpieza, que podrá ser? Hace 10 meses que la tengo
nice to watch a professional at work when occupational safety has been taken care of in a maximum way. After all, nothing can happen when the jack was still very stable and in good quality for performing such work.
Hello, I have a question. My robot starts cleaning with 100% of battery left and the last 4-5 times when it arrives to 40% it dies suddently. Before when the battery percentage was low it returned to the dock in order to recharge itself and after that it starts again, but now it stops itself in the middle of the room without any voice message. Do you think that could be the battery pack that is damaged and it is necessary to replace it?
смотри мое другое видео ... cells replacemen ... там я заменил все елементи из батарея и она работает до сейчас ( у батарея xiaomi там еест плат баланса елементь )
Thank you for this informative video. I have s5 max and do you think a regular 4s 20A bms works insteadof the original battery pcb? I see there are 4 cables. Two are plus and minus but I couldn't know the two other white and yellow one.
I'm not completely sure, but one of them should be battery temp ... but I haven't any idea about the other one. Try to repair the original board in my case, the issue was fuse located on the board. I've used fuse from donor board - laptop battery
Viomi Alpha UV(S9) remove all the main screws, on back of the robot vacuum, and then lift the lid from the front to access the battery, as per Xiaomi. Thank you.
Fantastic. However, We do not recommend DIY for wrapped battery packs, as the wrap is for heat installation, when charging. You can buy new battery packs, globally cheap from China for Xiaomi and Viomi brands. Thank you.
If the complete battery pack gives the correct voltage, but, through the connector that goes to the vacuum cleaner (4 pins), it only gives approximately 7v - 8 volts, what do you advise me to check? The cells have just been replaced, the vacuum cleaner only turns on if it is in the base to be charged and the batteries are 100% charged at 4.2v
I have the same problem with air spring and its making rattle clunking noises. Do you know what is causing this kind of noises? Thank you for answering!
здравейте, май така е по-добре, коментирах, като сложа амортисьора стои под долната част, и не мога да си го наместя. и исках да попитам дали има някакъв метод да го направя. поздравления
if you'r trying to mount whole shock assembly on car ... (it's a bit jerky translation) remove air valve and it will be way easier to mount shock assembly on car.
but if you are trying to assemble air spring with bushing inside this is really difficult, I've used magnet (on flexible stick - don't know the English word for this tool) to put together bushing washer and in the end to tighten everything. In fact this is the hardest part (in my opinion).
First of all, thank you very much for answering and congratulations on your video, it is very helpful. If you look at minute 15 of your video, my air shock is just like yours, but I can't get the bottom zone in.
Had my A8 serviced at the dealer till about 70,000 miles. I decided to do the next oil change. The filter was never changed by the dealer in all that time. A heat shield needs to be moved and creases after. It was never moved, and the oil filter was degraded when i fished it out. Guess they can't be bothered. Do it yourself!
@@chichovenci Great use of that concrete lift BTW. Back in the day, we used a couple of spare tires placed on the ground and a few bricks as a small ramp. Just drove up on the spares!
Thank you for detailed explanation! However, when opening the battery case, the component(likely AO4447A) below Thermal fuse(Sefuse D6x) got damaged and lost connection to the circuit board. Can I solder it to the board once again? Or can I replace it? Can you please guide me what can I do further? Your 3d model of battery case attached is very helpful , Thank you!!!
if fuse is "just unsoldered " ... check it with ohmmeter and if is still usable (operational) you can solder it to it's place. otherwise use compatible replacement.
