Popular Post techyiam Posted April 5, 2022 Popular Post Share Posted April 5, 2022 2 hours ago, Chriull said: With the new bms firmware which does not reset itself after some overburden/short circuit the biggest problem should be resolved. So either the upgrade or otherwise unplugging the battery should make the S20 quite risk free - if the statement of KS is about true. In a reply to an e-mail, Jason showed that he doesn't trust Kingsong prowess, and insisted they get the wheel certified by a third party. Now, Kingsong has only promised to get their battery pack analyzed. But the results are not backed yet, since Kingsong hasn't shared the results with us yet. So what is Jason to do in the mean time. 80 battery packs are a lot of packs. The packs might have come separately already. If that is the case, he just may have to stored those packs outside separately, away from his regular warehouse and tech center. 4 Quote Link to comment Share on other sites More sharing options...

After beeing burnt once it'll be hard to rebuild trust And the prowess they just showed does not help rebuilding anything. The motherboard/microprocessor should never ever get into an uncontrolled state and _stay_ there forever- like this periodicly drawing huge currents. And a self reseting fuse with such short delay for a liion battery just blows ones mind... Unfortionately ks is not alone - it's just a matter of time until the next manufacturer surprises us again. 5 1 Quote Link to comment Share on other sites More sharing options...

DjPanJan Posted April 5, 2022 Share Posted April 5, 2022 Dont take any information seriously by ekolka.cz this seler stop sell veteran and begode wheels and start promoting selling V12 and S20 now after V12 mosfet drama and S20 fireball edition he is in trap with many euc in shiping state and he MUST sell what he receive or bankrupt this make him in bad situation.(not only him all selers worldwide) I personaly buy my sherman from ekolka.cz and i have nothing against this shop/owner they are good seller but not take this shop like official kingsong information source thats all. Ekolka.cz have only one official EUC service in our country and i am like EUC shop/repair is here in Czech Republic. Quote Link to comment Share on other sites More sharing options...
supercurio Posted April 5, 2022 Share Posted April 5, 2022 Okay @DjPanJan I hope EKOLKA will make it, they've been producing good quality content with even an effort to make it accessible by an international audience. Let's ask more distributors to see if they confirm that. Quote Link to comment Share on other sites More sharing options...
supercurio Posted April 5, 2022 Share Posted April 5, 2022 Thanks for the previous links, I'll paste the whole content here: Source from EKOLKA Facebook post Content (auto translated) Quote KingSong's management decided that starting today the S20 model will be named S22. KingSong S20 had a critical fault in the firmware, which in exceptional cases could cause a battery overheating and the following fire. In the new model, the error will be removed not only from the firmware, but additional elements will be used for electrical protection of the article itself and the battery as a whole. What do we think about it? No S20 has been offered to the public so far, so far we only had pre-production testing pieces, which are designed for testing in different modes and to solve all possible problems. It's good that we have a similar option before the launch of the big robot and that KingSong immediately responds to the reported problems Today our S20 was racing in quite aggressive modes (gas/brake), fell several times and everything still works as it should So far we do not know exactly what happened to the machine in America, but it had at least one crash, they also reported that maybe it was drowned. The baseboard is on its way back to China. The manufacturer should comment on this. Then they posted a copy of Kingsong's report, which does not include what EKOLKA says on "additional elements will be used for electrical protection of the article itself and the battery as a whole." They kind of discredit their own post however by saying "they also reported that maybe it was drowned", which was not the case. @DjPanJan, is this automatic CZ translation correct, with "drowned" ? 1 Quote Link to comment Share on other sites More sharing options...

Also, don't forget the 18L's had a glitchy start for the first 9 months (causing over current which required disassembly and battery disconnection). I had to take mine apart 2 times. 9 months is a long time to wait for a FW update to fix something. 1 Quote Link to comment Share on other sites More sharing options...

I believe "submerged in water" is used more often here on forum. As they are not native czechs, it could be a little "encrypted". Unfortunatelly Im unable to identify if their post was created first and immediately attached KS reaction (one message) or there was some time delay (assumption and reality), I saw it was same day (I expected 1 splitted message). 28th we talked about it and I gaved them our big sceptic feeling in case of only fw solution. They have good connection to China and imports more kind of different goods (higher ability to understand Chinglish? contacts?). But I can agree, V12 and S20 is worring more sellers. Long story short - I will ask them to verify the message. 2 2 Quote Link to comment Share on other sites More sharing options...

Well count me in for the after-market replacement batteries. hmmm I wonder if I can make them hot-swap like the batteries on my Dewalt tools. Maybe even use the same connector to connect them! Maybe the quick-swap could also solve the lack of a drain hole in the bottom too. Like if the connectors at the top self-guide, and a latch rather than screws on the bottom. hmmm Edited April 6, 2022 by Elliott Reitz Quote Link to comment Share on other sites More sharing options...
RayRay Posted April 6, 2022 Share Posted April 6, 2022 15 hours ago, PourUC said: Loads of wheels have had their batteries go into thermal runaway. The jet like affect isn't some super defect that KS have discovered. It's just thermal runaway inside an enclosure with a small exit for the fumes and flames Imagine a rider is momentarily stunned by being thrown off a wheel and can't get out of the jets way in time. KS may not have discovered, but the KS20 made us aware of super unlucky possible thermal runaways risks. 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Jon Stern Posted April 6, 2022 Popular Post Share Posted April 6, 2022 You can fix an issue that has shown up in your product, but what about the next one, and the one after that? Rather than focusing solely on the one failure, better to focus on the flaws in the process that allowed the failure to occur in the demo unit. Fix an issue and you eliminate one problem. Fix the process and you'll prevent a thousand problems down the line. I had an engineer working for me who had worked on Xbox. The infamous Red Ring of Death (maybe that's a good nickname for the KingSong S202 Eagle?) cost Microsoft a billion dollars. It would have killed a smaller company. In response, and to their credit, they instigated rigorous and comprehensive six-sigma training, brought in consultants including the excellent Philip Mayfield from SigmaZone, and overhauled every aspect of their product development process to avoid similar issues from happening again. This is what KingSong should do: train their people in design for Six Sigma, and study the automotive ISO26262 "Road Vehicles - Functional Safety" standard to see what aspects of it could be applied to their business. The overheads might add a little cost to their wheels, but it would help avoid the risk of them killing their company through mistakes of the magnitude we are discussing here. The costs could probably be more than offset by the marketing value of this new safety culture, in marked contrast to their competitors. 8 1 3 Quote Link to comment Share on other sites More sharing options...
Popular Post Tawpie Posted April 6, 2022 Popular Post Share Posted April 6, 2022 I want this culture to manifest itself in the EUC world... badly. But remember that we the consumers, have allowed it to persist. It sounds like eWheels is taking a stand, they've done it before. When we make purchasing decisions we are validating a company's practices as acceptable, this means we as individuals have responsibility as well. Processes need to change at all the manufacturers, even the performance leader—they don't get a break because their wheels go like the dickens, it sets a low bar that the rest are tempted to emulate. Maybe? we're seeing the start of changes. Openness. Independent design reviews. Delay shipping (or refuse to ship) if you need more time to fix something. Vote with your wallet, and be sure apply the same standard to whomever you choose to purchase from. 7 2 Quote Link to comment Share on other sites More sharing options...
Paul A Posted April 6, 2022 Share Posted April 6, 2022 There are valid criticisms of six Sigma. Refer to wiki. https://en.m.wikipedia.org/wiki/Six_Sigma#:~:text=Six Sigma (6σ) is a,to be free of defects. Six Sigma might not be beneficial to current EUC manufacturing. Small size of EUC manufacturers, small workforce, low production volume. Measurements and objectives of Six Sigma, might not be as well suited. Seems similar to Japanese Kaizen. Incremental improvements to well established processes. Great for companies like Motorola, Toyota, maybe not as well suited to EUC manufacturing currently. Might stifle large leaps in innovation/thinking. Wiki references failures of Six Sigma. Quote Link to comment Share on other sites More sharing options...

However, at the back of my mind, I thought something doesn't add up. Then I had a chance to hop on one. I can say that it has a premium, refined feel, that is higher than the V12, and many other wheels I have tried. Coming from a T3, it was more intuitive to ride than let say a V11. Despite what people say that it lacks a damper, when I jump up and down on it, the suspension action was clearly damped. Thanks for your review.
