Endless Sphere

all the packs I have, have the BMS on the very top(on the four top cells) I got packs with 3 different BMS boards, mine where samsung 22p with 2 different boards on the side and a board in between. Some packs where crushed, but got refund for. I did not found any info on those LG initially so i wen...

Plus, i do each test minimum twice to be sure in the results.

Very good info you are providing about cells, following you on several topics.
Your accent does not appear Russian by the way.

Overtheroad diesel truck engines and farm tractors are operating at 40% efficiency so this is not that bad considering the truck can stop for a 20 minute fuel up and take on 400 gallons of fuel which is 15,000 kWh. Yes, there are many mental deficiencies to overcome in areas of sufficient infrastru...

Metal is much more useful than stone for tools. I see a ray of sunlight. So, what about 4-5x energy conversion efficiency of EV to ICE. (think 5 stone hammers to 1 metal hammer) Liquid fuel is ideal for moving things around. No, they are ideal to produce heat, it is what they do moving ICE mainly. ...

Fuel outlets will not diminish until after liquid fueled vehicles diminish. The liquid fueled vehicle quickly replaced the horse since they quickly became much more useful for transportation than a horse. Stone age ended not because stones where over. There always will be some use fore stone and fo...

Remember, you have to interrupt <4.2V circuit and only a dozen or 2 of A current capability. This depends on the specifics of the battery pack it's used in. With many parallel cells the fault current could get quite high if a single cell were to develop an internal short. 1) The fusible link will b...

I suspect that the tiny chinese glass fuses would not have a high interrupt capacity because the internal volume of the fuse is quite small Remember, you have to interrupt <4.2V circuit and only a dozen or 2 of A current capability. That is not really a plasma danger level and discussed fuses have ...

and my price limit was 1000€. I like the philosophy and service of Kelly Controls much, much more! So here the story of using a hubmotor in a motorcycle ends for me and I will change now to chain drive! You also can use this hub as mid drive, if you have enough space for. Winding job takes several ...

Fuse wire and mentioned glass fuses are less then ideal for discussed job. Ideally it should be: 1)low heat conducting material with 2)high current conductivity, 3)confined fusible area and 4)protected fusible area What comes to mind is following fuse design with fine, zink based fusible link http:/...

Turns out most of what I thought was charge current was actually being routed to other systems thru the power block on the + terminal. The problem will be if you have almost discharged battery for some reason. After start, generator will try to push in all Amps it can generate. You can end up with ...

Looks like some defective winding job in the burned section, some short maybe. Usually, the winding gets charred evenly all around and then just bursts in place where charred insulation fails first. 1. Feedback sensor: Which sensor type will be the better one for the high current and therefore force...

That looks really cool. Nice CNC.
Why are you using aluminium for connectors?
My first thought was copper, I used it finally as well with some contact grease on (aluminium will need some oxide breaking compound to).

What is the problem to open the motor? Normally you pry open one side cover (hammer and chisel) , which is glued on normally, as usual, then push out stator, if needed, with some tool or just jumping on the tire with axle on the floor. Please submit some pictures, you are facing a problem that was r...

Nice holders.
What is the thin, transparent base, underneath your print?

Chernobyl At least this 1 was a human error, more inclined to sabotage. They did programmed runaway stress test with all security protocols shut down, but moved the test schedule and it fell on other shift, where unfortunately was no trained to deal with personal. The security system was designed t...

Once, in 2008 I woke up in the morning because of people running and screaming on our condo parking lot, my neighbours car was on fire. I was able to get in to my car and drive it away with minor bubbling starting on the paint-gob but we could not extinguish the fire on burning car whatever we did, ...

If you are conncected the button is at the bottom right. I know what you mean (I have seen screen shots with RUN button https://play.google.com/store/apps/details?id=com.vortecks.vbms&hl=en_US, there is also 4th screen mode I can not find), but I still have PARAM2 button there(like this http://i105...

here is mine:

Thanks, but it looks exactly the same I have, there is no RUN button or I am to dumb to find it.

i will post my version of VBMS during the weekend. Please, I still have hope. I printed enclosure for the screen but there is no way to get it on and still use buttons. A cell holder will work, it is optional and there is front access. P.S. If anyone wants the box with buttons for the screen module...

I think you are asking about these 24 and 32S smart BMS and the LCD....which is the only real dashboard. The LCD is nice, I have 2 now and the info on first screen is about all I need but unfortunately I did not find any space to mount it, with access to the buttons. VBMS can do that, hit "run" aft...

Is there any APK or mode in existing one to have nice dash on the phone screen? Something similar to 1st BMS screen, just with basics like TotalV, Ah, lowest cell, highest cell, maybe speed. My APK has 3 screens that are useless for anything but programming and deep analysis. 1 is log screen with so...

Or even better: post the english apk file! (for the BMS-Ant please )

I tried other apk, similar but other maker and they did not connect to my BMS,s. So, there is a chance this one not going to work with yours.

The weak spot is the insulation on the wires, inside the confined axle channel. To toast the winding you usually need to heat up the whole stator over the insulation enamel rating, somewhere north of 120C. You would feel the heat radiation of the stator in your faces skin just looking at it in this ...

A short video showing smoke is coming out of the motor:

Looks like toast phase wires from the video. Did you upgrade them before pushing that far?

What is different on your BMS? Do you have a link? There is one sink (actually just an aluminum plate) on each side of the BMS. One is for the balance board, the other for the FETs. So two sinks in total. It looks like one you linked, the pictures are of a 24S BMS at least, but yours is 32S and mus...
