Can I ask, what safety features are implemented inside yours BMS? What grade of battery LG INR21700 M50T are you using?

Question did the battery pack rupture in some way, or was the short/problem in external wiring? The shorting of pins in the charging ports is always a possibility, it takes the addition of one component (a diode suitably rated) to prevent this.

Is there a certain batch that is prone to this issue? What is a good way to DIY this issue if we already have a RS19 or any other Begode wheel?

Lithium doesn't mix well with water ,snow,salt ,rain . 💥 All Euc are not water tight . In the owners manual it says to not ride them in theses conditions .theses wheels that blew up all road in theses conditions , snow ,water ,mud, salt

@@jkingsrd1 I don't think in all consciousness a manufacturer can use such a statement to exclude themselves from making wheels safe, as much as possible, in the conditions they are likely to be ridden. Do we really believe these things will not be ridden in poor conditions both intentionally and by accident when conditions deteriorate miles from home.

The v11 is definitely well built. It does have a design fault tho. It's the lights wires and one of them go right over a capacitor on the motherboard. Easy enough to fix. Other wise v11 has sealed batteries case. That alone makes it harder for external issues to effect the battery packs.

@@toddlarcombe8973 Hi Todd, I guess you mean the cables that go to the back tower? They are not connected to the site of the capacitor neither to the same PCB board. Instead, they are connected to another PCB installed on top of the control board. The cables pass close to the back part of one of the two big capacitors towards the tower on the back. They are for rear lights, speaker and power source for the USB port (5VCD/2.1A). Being low powered and close to just the back of the capacitor (not the electrodes) I do not see much of a risk there. However, everything can be improved and I would happily agree with a common standard in the industry about covering all wires until their connector, with anti-flammable socks unless the insulation material of the cables already has that property. On my mods I use cables rated to hold up to 600ºC. I do not know if these are of that type but I am ok with having them in the opposite side of the electrodes and of course not in touch of the MOSFET. Bugs on the V11? of course it has them too (of a different type though). I am working on a mod to extend the upper valves of the suspension to not have to remove side covers to adjust the upper chambers pressure. Also I wish the back PCB with the charging ports to be more insulated. Everybody uses the same plugs but I wish something that could be more tight and waterproof closed. I think is better to have them on the stern as the V11, rather than the front (more exposed to rain etc). But still I wish an easier way to plug it and safer. Crazy idea, what about well separated electrodes on the pedals, that connect with a stand, ONLY becoming hot when the unit is off and on that stand? No more exposed plugs... just brainstorming. thanks

Hope you are ok now!

@@krikri3387 I was planning a trip back to Phoenix but had to postpone it to buy new protective gear a lot of my stuff melted in the fire

I am sorry this happened, but so glad you are fine. I recall the drone industry had similar issues in the past and they improved on safety so much. Like smart batteries from DJI capable to self-discharge to safe levels when not used, with multiple sensors etc. I wish this approach could be transferred to EUCs. Also the chargers tend to be just generic units without even a cooling fan inside, nor the smart capabilities we would like them to have. Like smart chargers for drones that can balance each battery cell, check temperature, really cut the current when achieving a designated level etc. EUCs have gone far on increasing speed (to levels that in most of the world is not even legal), but still there are safety areas to improve even on Inmotion and KingSong units. Take care Tyler, kind regards

Seeing how eucs are made compared to electric boards - tangled cables, unprotected motherboard, they look like they were put together by blindfolded children.

@@eskaterspoland And on top of that QC (quality control) doesn't appear in their chinese vocabulary but there are still people willing to (over)pay any price for these machines saying the price for it is right. Ps. Greetings to you Dark Star :D

Pozdro :D

Yeah. It's important to remember these problems are relatively rare. These fire videos are evoking a lot of emotions.

Where is solutions to the old issues?

interesting to know. Im just curious if there are a certain batch of these wheels that are causing these rare incidents.

Begode/Gotway is clearly the worst though with fires and build quality.

Still though, Gotway has a known track record with their (lack of) quality control, there are far more exploding Gotways than exploding Kingsongs or Inmotions.

That Monster Pro is dangerous with the motherboard practically touching one of the battery packs

Don't worry. This Monster Pro had been worked on and we don't know what they potentially did to the wheel while working on it. Could be a random failure but I suspect it's not random.

I don't think he gave them a pass. The last time he took apart the Sherman and the equivalent Gotway, he noted that the Sherman had superior build quality.

@@arevee9429 Just look at the history.

Begode just doesn't give a shit by the looks of it. They just slap shot together, and dont implement any safety features.

Gotway has also to reprogram the input current demand management or/and consolidate weakened input current sections on the motherboard

That's what you get for riding this brand wheels outside. There's too often water or dust or mud on the ground.

Let's be realistic here though. Something that can set your house on fire because it gets a little moisture in it is dangerous. Try selling something to the general public that is advertised as an outdoor vehicle, but can't get wet, or else it catches on fire, lol!

@@waldemarjurkowski6037 Thanks for making that point! It makes me feel better to know that not just EUCs are catching fire. With so many things being powered with batteries now it makes sense that they are going to be more fires... Whether it's in Cars or anything else that is powered buy batteries. I don't really watch the news so I live in a little bit of a bubble. Initially this video was traumatizing for me. But I'm over it now. I am going to put a fire alarm directly over the place where I charge my EUC though! ;)

THE FIRE IS TOO POWERFUL IT WOULD BURN RIGHT THROUGH THE FIRESAK

Hi, is there a link to this information about a whole cargo container on a ship catching on fire because of a Gotway machine? How did you receive the information? Thanks.

@@PaulA-pm3gx kzfaq.info/get/bejne/nLJyhapoldaqqWQ.html Here you can see that

@@edgarkazak5228 Thanks for that.

Most.ot the heat in ESC are produced bt FETs. Where is gonna be not much effect on them, they are glued and bolted to radiator in most of the times.

kzfaq.info/get/bejne/Z92Tf7mX3MqcnZ8.html

yes I use CorrosionX on my EUCs, but as anti-rust enamel. Not over the mainboard (specially the hot MOSFETs), but on contact sites between two different metals. Instead of CorrosionX, there are specific enamels to insulate PCBs. Inmotion add this protection to all mainboards and I believe KingSong does it too. Also, their batteries are encased properly.

@@gpsanino I've seen RC boaters simply spraying down everything as a final step to keep salt water off all electronics. It does not conduct electricity. However RC is much lower amounts of current.

my friend has v11 for 3 tears and using it all the time.. good build quality

That apartment fire was unrelated I just checked, but a few minutes searching and already found these, July 2019 facebook.com/groups/ElectricUnicycle/permalink/2271409086290375 May 2020 forum.electricunicycle.org/topic/18494-warning-gotway-nikola-100v-1800wh-battery-fire/?fbclid=IwAR1xBEOburOqKUDFIi0ONN1msly5Z47URXEQheP1dhd26qWzCZLfuiKOQEg June 2020 facebook.com/groups/352845635409860/permalink/590989134928841/ August 2020 facebook.com/groups/GotWay/permalink/2523128201078820/ Dec 2020 facebook.com/groups/ElectricUnicycle/permalink/3525270547570883/

I recently bought a secondhand Nikola. I was already not thrilled by Gotway's history of quality control, but I couldn't find anyone selling a used 16x at the time. Now I think I'll cut my losses sooner rather than later- I'm probably gonna trade it for a V10F.

I do not think so. The hollow-bore motor produces even lesser heat (friction). On many brand EUCs you will find cases of fried mainboard fried, but without resulting on these huge fires. Specially on Begode style of unicycles you will find that batteries, cables and totally exposed mainboard are all too close, with little insulation and thus, any circuit issue has a higher chance to ignite plastic and later the battery cells increasing the emergency. Insulation, encasing, better design and manufacturing standards are the issue. We still do not have a minimum safety standards for manufacturing these vehicles. Therefore is up to the "market" to select safety rather than speed. The hollow-bore engine is a huge advance introduced first by Inmotion since with it the cables with the highest current are no longer compressed into a small tunnel inside the axle.

That’s true 👍

has nothing todo with the cell type (at least if its an official GW Monster Pro and no chinese battery upgrade). This „runaway fire“ of lithium cells just can happen...its seldom, but possible. The used LG50 cells are totally fine.....

I'm pretty sure it's more about them doing the absolute least amount of work possible to get the wheel running fast and not exploding too often. That means omitting multiple safety measures in the electronics.

@@4nlimited3dition_4n3d There ARE the same safety measures as other producers have. Over/undervoltage, balancing, short circuit etc etc . These are all on the BMS they use. The only thing they dont have is a short circuit protection on the charge plug...which isnt the culprit for these burned wheels. Dont get me wrong...i am NOT protecting GW, they have a pretty lame quality control. But its hard to blame them for battery fires, these can occure with each and every Euc/Scooter/whatnot on the market. Its just that most riders are not aware this can happen.

​@@ullle66 You are speaking as if GotWay wheels were even close in terms of safety or quality compared to for example Inmotion or Ninebot. That is not the case, at all. Firstly, the GotWay battery and control board compartments are not insulated at all. They are literally just bare and exposed under the thin plastic shell, which itself isn't even fully weatherproof on most of their models. Secondly, the workmanship on the component level, soldering, circuit design and such, is also absolute horror, especially for a vehicle that relies on the board functioning 24/7 to stay upright. Thirdly, their quality control is non-existent. One batch might randomly have 3 explody wheels while the second batch could be using different caps or fets and have lower performance and none of that is even listed anywhere.

Ibanez RG1570 Prestige :) love that thing

@@mr_wrongway nice!

Not sure if there's really a statistic value of how many begode wheels have been destroyed due to fire, but id say it's pretty rare. Just take care of it, don't stuff it in super hot places, don't ride in the rain etc.

unfortunately my gotway MSP set my house on fire and my 16x, it had only 5 months of use and is not charging at the time of the accident. it was horrible, just despair. videos here on my channel.

Yeah I will do that :) Sherman has fuses and motherboard is separate. I rode in snow and it was fine :)

I have a extinguisher now and I will seal my wheels better. I can sleep

it doesn't depend ONLY on that, in fact too many other factors are more likely to cause this kind of issues

LGM50T 21700

Even the highest quality cells can explode and start a fire if shorted by external factors, such as moisture, or a control board failure.

​@@4nlimited3dition_4n3d yes it is correct. Do you remember when many of the v10f catch fire and v10 never. Same construction, same number of cells, just different one. Read about li-ion chemistry. Some are more dangerous then other and there are plenty of different types of li-ion battery.

​@@rerkey I only remember the early V10 models having waterproofing missing and thus some caught fire, because water got inside. But they recalled it and fixed it a long time ago. Still waiting for Begode to do the same for 3 years now.

Ask your seller :) but I think it might be normal :)

@@mr_wrongway Yh thank you

@@mr_wrongway also I was told I have the third batch which I received my wheel in November and I rode it in the rain a several times and now the wheel make a weird sound when riding it like a scraping sound like it needs crease not like how urs was but it’s still fully functional tho

No. Batt pack installed not by factory though but with exactly the same packs

Dude! It us not a submarine! Salt water is dangerous! Why do you think these machines are waterproof? Has this manufacturer ever claimed this?

@@telki5978 Only Begode wheels go boom every week. Other brands, it's much more rare. Wonder why.

Yes, sure, these are the safest cells, but than instead of 1800wh a GW RS would only have about 1000wh and would also weigh about 20% more.... Problem with LiFePo4 is that the energy density is MUCH less and the weight is even more...

With Sanyo GA cells I think so. Less voltage and I think better seal

I'm looking at getting a Tesla V2 or a inmotion V10 but this is swaying me towards the V10....

@@squeaksb4897 the Tesla has a completely different and much safer design than the MSP/MSX/RS. Check Tishawn’s in depth review in which he opens up the Tesla to examine the beautifully safer internal design 🙂

@@squeaksb4897 Also, notice how the batteries have their very own compartment - separated from each other AND from the Motherboard - which sits on its own metal shelf, which in turn, sits on top of a plastic shelf that separates it from everything else: a brilliant design that sets the Tesla’s apart from all that was unsafe and criticized in every other GW wheel before kzfaq.info/get/bejne/o6xpib2Cu9_WnY0.html
