Battery builder here. That green cardboard/plastic stuff is called fishpaper. It's oil impregnated cardboard that's fire and abrasion resistance. I agree the corners are a weak point, if I were to build this battery I would use fiberboard then heat shrink around that. On the subject of no short circuit protection, that can be fine as long as a fuse is used, but I don't see a single one. If the BMS was used for short circuit protection it may have a problem with surge loads and high speed cutout, it may risk the battery but under no circumstances do you want the wheel to just shut down at 50mph. I disagree on the output pins being too close to each other. You would need full submersion to get enough current going between them to be a problem. Regarding MOSFET burn segment. I'm not quite sure what he is getting at, those MOSFETs are small, but will sacrifice themselves in the event of short circuit. I don't see a problem here. Oh, backtracking to mounting. Since the shell is plastic, even if the battery was worn through shrink wrap and cell wrap, it would not short. (But yes, water ingress is a concern in worn shrink wrap) 24:20, I think you mixed up some connectors here. From charge port to battery is an xt30, that's 30a max, not a concern since chargers top out at maybe 15a. From battery to controller (the bit you were holding) is xt60 for 60a. This is within spec, but I agree xt90 and thicker wire produces less heat and has greater current overhead. Overall there are just a few things I would change, add fuse, add more abrasion resistance on the outside of the pack, wire the charge port to c-, and add a simple diode to keep the charge port cold when charger is not present. These changes could be added as in-line adapters and packaged for users to easily install for maybe $20. Begode, hit me up, I've already got the design in my head.
@@pashko90 with the amount of power in that battery, any of those fets would be blown apart violently if they had a full drain, source, trigger short. Anything is a fuse given enough power.
What do you think about cell-level fuses? I think battery fires are way too common in EUCs. How would you prevent them? It seems like a cell-level fuse guarantees that the battery won't catch fire since it will only allow moderate amounts of current, which won't heat the pack enough for a runaway, and the only risk left are since cells shorting themselves inside or with the casing. Maybe using LFP or with better cooling, or temperature sensing?
Try taking apart KingSong battery packs (particularly pre-2021) and Veteran battery packs and notice how similar they are to Gotway. Inmotion and Ninebot always took there batteries and packaging more serious. But if you want to be fair you should peak under the hood at KingSong battery packs (and maybe Veteran, consisting of ex-Gotway employees). Things might not look so rosy there too. I can tell you for a fact that the Sherman and most of the KingSong wheel battery packs are packaged similarly with the same susceptibility to abrasion against the shell plastic. It's OK to dump on Gotway (I've done my fair share) but perhaps the same critical eye should be applied across the thousands of KingSong (14S, 16S, 18XL, etc) and Sherman wheels that have been produced. I may be surprised but I think there may be more similarities than not. How can you in good conscience sell these dangerous wheels to other riders? ;-)
Totally agree, it doesn't make sense about concerning safety of a Begode owner but selling it to others would be ok. Review like this is great though for we understand the technical issue and make the manufacturer learn and improve their product. I know Begode/Gotway improve already their quality but it's not there yet but they are and same with other manufacturers. I know Adam will consider Begode wheel again for I could still remember the face of enjoyment when he used a crappy quality Begode wheel😉
I’m planning to check those other wheels too. However the hot charge port and no battery current limit/short circuit protection on Battery/BMS is a trait only at GotWay.
@@mr_wrongway Agree about the charge port. Not sure about the short circuit protection - if you go 3+ years back (a lot of those wheels are still out there). But yeah, if you do have the opportunity, please apply the same level of criticism (in this sense, good and bad) levied against Gotway to the other brands. You might end up only owning a V12 ;-)
Great job Adam, really appreciate this deep-dive into battery safety. Quick PSA - for those who are concerned with improving safety for their older Begode battery packs, you can always add a 30A inline fuse for each pack too (just make sure they are disconnected first of course). Also for US riders, the vendor eWheels outsources their Begode battery pack assembly to LiTech and feature many safety improvements including imported Korean Samsung 50E cells, short detection/protection, inline fuses, voltage differential management for packs of unequal voltage, improved cell-holders for better survivability in the event of crash, and more. I wouldn't own an RS if it weren't for their safety investment efforts so I like to give them a shout-out when it's applicable.
this is dangerous and may cause cutouts because the mainboard doesn't take into account that there's fuses and will draw as much power as before. there should be oversized to decrease risk of a cutout, maybe 40 or 50amp IDK.
@@osimmac That's a good point, the maximum battery current limit set by the wheel's motor controller isn't really defined in a publicly published manual, at least from Begode wheels. Instead, we are assuming the Battery Current limit from the stated 2600W power limit for an RS as an example. That's 2600W/(3.2V LVC *24) = ~34A). 3.2V being roughly the Low Voltage Cutoff limit set by the motor controller. Since eWheels uses a 30A battery fuse for their LiTech packs for the RS, it can be inferred that Begode is limiting the battery current draw as the pack voltage goes below 50% SoC. This is consistent with the riding experience limiting power as the battery level approaches 0% SoC. For other wheels that haven't included battery main wire fuses, you could try emailing the manufacturer for their recommendations on fuse size. I agree with you though that over-sizing the fuse some probably wouldn't hurt if you don't know the exact Battery Current limit since it'd probably still break the circuit before thermal runaway and battery fire occurs in the event of a wire/connection short.
Thank you for addressing batteries and allowing conversational awareness to wheel maintenance in terms of battery safety. I learned a lot. Please next time address that the technology across all wheels are roughly the same and not isolated only to begode/gotway...you don't want people thinking that they can abuse an immotion/Sherman wheel expecting it to not catch in flames also.
Charger port pins will explode when you stick fork in the charge port. My 3 year old boy did try it. After that I bough screw on charge port covers from Ali..
It was a very good video, thank you for this. While it's interesting to look at one pack by itself, I think there is an inherent issue with the battery topology here with 2 packs directly wired in parallel. And this topology can result in cell ignition in a specific case which we've seen happening: 1/ one or more damaged cell groups in pack B. Pack A is fine. 2/ the BMS can't keep pack B balanced. 3/ the damaged cell group self-discharges, reducing the voltage of pack B. 4/ healthy pack A doesn't self-discharge, so its voltage is higher than pack B. Now, it's charging pack B. 5/ as the process continues, damaged cell group keep to discharging and lose voltage while every other cell group in series has its voltage going up 6/ some cells groups in pack B end up beyond 4.2V 7/ ignition, fire. And there is no mechanism to prevent that to happen in the BMS apparently. Or maybe only in some damaged BMS. So it's very important to disconnect packs from the board and each other if one of the EUC doesn't charge to the max voltage anymore. Otherwise this process will happen over two weeks, with a likely fire as a result.
That's why the packs communicate between eachother with those extra wires. When one pack cuts the charger, then the other pack has to, too. If not the healthy pack would charge the overvoltage pack through the parallel output. When people make add-on packs for their gotways like 1600 to 2200wh, then they often forget this functionality = danger. The add-on pack could overcharge a bad pack in the system.
Another reason I love Ewheels. They had a third party put different and safer battery packs in the RS's before letting them go to the consumer. Also giving us a chance to choose different different battery options. Makes me feel a little better.
It does make some sense to have foam cushioning around the battery pack and allow some movement as this reduces the force experienced by the battery due to hitting pot holes or in a crash. This would be the equivalent of anti vibration mounts or crash protection, although in a simple form. The implementation could be better, for sure but it seems to me that the tight fit and use of double sided cushioning tape is sufficient to hold the units safely in place. Just my thoughts and feelings. A solid enclosure would lead to impact forces being transferred to the internals of each cell.
Always helpful!!💯👏👏 As we talking about safety... Do you know the most powerful and expensive e scoot RION, use BMS ONLY for charging....😲😬😤 You pay almost 10000 euros and they don't put a good, big, BMS for discharge... And we are taking almost a 100v... Made in USA... From Greece 🇬🇷 with love and Respect!!
as a person, who working over 15yrs with electronics, i can say, i l'm sad to see that. "BMS" looks very dangerous for me. This is not a smart BMS, cheapest thing what they can insall. I do not understand, what was been a problem to add a fuse to Charge and discharge sides? as well lack of casing and fiberglass laminate sheets on this sides, at least? Imho battaries needs to be glued to wheel case as well. No super-all way thru, but they adre not suppose to rattle aroind as well. Ant bms or any other smart bms should be a good choies for wheel like so. I'm really interested to see what is going on inside of this wheels. :/
C+ port has diodes so it allows the current to flow in only one direction. If it was used it would prevent sparking, short circuits on the charge port, and allow parallel battery pack connections without one battery pack charging the other pack. However those diodes have a finite current rating, and heat Dissipation before they burn out. Fast charging would be really bad for those components. Probably even charging when the batteries are discharged, and draw more current when charging. Normally this depends on the diodes used.
On the GW BMS the C+ port is DEAD…you can see arrows on the BMS….there SHOULD be the diode, but there is none. I have build packs with those GW BMS and i used the C+ port….the pack doesnt even charge then. I had to resold the c+ wire to b+ as that is the only way charging works here. (or one can fill the arrows with solder, but then the chargeport STILL would be hot)
Good video Adam. What conectors are used by other EUC manufacturers? XT60 are rated to 60A continous, not 30A. So 3 battery packs 60A*3=180A. More than enought. Easies and chepest way to fix the short circuit issue is to add fuse to each battery pack, as well as for charging port. But sure it is good to point all the weakness in the video. Hope it give Begode strong signal to improve.
Thank You very much, I still have to approach the EUCs world, but that's my intention :) so, I extremely appreciate all of Your efforts on doing such videos, therefore all of the community can make proper choices and be safer. Thank You (from Italy :)
Another great video, and the fact you are selling up is amazing. It will lead to Gotway sales dropping faster and faster, as I have said before Gotway will only change and develop if they are making a loss. To be honest I think that it is too late.... at the moment if you want a performance wheel you have the V12 and KS20 on the way, and within the next two years there will no zero reason to by a Gotway. I only hope the both Kingsong and Inmotion produce a 10" and a 14" wheel both massively important wheels. Tear downs by both you and Marty leave nothing to the imagination.
So good to see reviews regarding the safety of all this electric gear. This is still the wild west as far as manufacturing this stuff is concerned and companies need to know that if they cut corners and build potentially dangerous products, they are going to get exposed. THANK YOU.
I think your words and actions are justified. Hopefully others follow suit. Safety should always come first and now KS/Leaper/InMo are bringing us performance wheels with safety and proper engineering :D
There are certified battery specialists around, who make up custom battery packs from scratch. I know an RS19 owner who's looking at having 2 x 900wh Molicell battery packs made up. I assume that could include a more advanced, better wired BMS board & maybe better protective covers (if requested?). Considering the same for my 2019 Nik+. Possibly cheaper than a new wheel? 🤔
Cheaper than a new wheel, perhaps….depending! 2 x 48cells Molicell would not be 1800wh…it would be about 2 x 740wh. When you make those packs yourself you probably get cheaper, as the material is about 500euro cells plus 200euro BMSs. But letting a pro do it? depends on his work costs
One job I had was doing qual testing for life safety and security devices. This is why standards exist and if your product doesn't conform to them you may find yourself not only restricted from those markets where those standards apply but also under investigation if enough dangerous incidents are observed in a period of time. If your product ends up harming someone, in the US the Consumer Product Safety Commission may come knocking and not only does that just clobber your delivery schedules it costs you a lot of money to make them happy again, so you can return to shipping to the US.
If they're smart, they'll hire a couple very competent engineers, have a fast recall, cross ship people their replacement wheels/parts, designate regional shops that can help people perform recall services if they don't feel comfortable doing it by themselves, about the same thing Toyota had to do when the Lexus unintended acceleration thing was happening. As soon as it was publicized, they got on it and it got resolved (the government was watching). They need to do same here. It's the right thing to do anyhow, just do the right thing right is all. :-)
If you want to have two battery packs in parallel 'same port BMS' is the correct way to go. But - Usually there is a protection diode and charging fuse.
If you live in an apartment building, and you buy a begode. Is that even responsible at this point? If a neighbor in my building buys a begote, don't know how i would feel. Am I overreacting?
Thats - in MY view- a bit overreacting. The reported Short circuits dont happen out of thin air! Control charging (dont leave it alone), plug off when ready with charging, and then while the wheel just standing their there is pretty much no pssibility of a short happening. The most GW fires still come from abusing the wheel/battery……so dont do that, too. Drive with „sense“. I for my part have a smoke detector directly over my wheels, and they are near the door……thats the best safety practices i can imagine. And be aware: a venting battery -just because of ONE cell becoming chemical bad - in the end that can happen on EVERY brand EUC. That is just THAT EXTREMLY seldom…..i dont even have that in my mond when thinking about battery safety. One who is THAT concerned….should nt carry a cell phone in his pocket, too!
@@ullle66 I'm not going to pretend I understand much about how, and why the fires happened. I hope you are right! Just don't want something bad to happen in an apartment building for example, and get us all banned for the city's and buildings. You know, they, the news, never differentiate the brands, it's going to be like "EUC dangerous" not begode.

Thanks a lot for taking the time to do such a great video. You got my like (not often given)
Someone wrote Another reason I love Ewheels. They had a third party put different and safer battery packs in the RS's before letting them go to the consumer. Also giving us a chance to choose different different battery options. Makes me feel a little better.
The takeaway seems to include: use these wheels in the wrooong waaay at your own risk and responsibility! It should maybe be borne in mind (in fairness to Begode) that the way you have ridden your own personal MSP could be shown as a very strong test of what the wheel’s battery packs have managed to withstand, and nobody (including Begode) have at any time endorsed either riding in wet conditions, nor riding in ways that could conceivably cause damage to the wheel or the battery packs inside: in essence, if you risk dropping or crashing your wheel, or damaging it by riding in any type of ‘hard riding style’, then you are personally risking a short circuit or fire. I absolutely get that the battery packs are not well designed in terms of passive safety, and indeed it would be good to see a redesign to address this potential danger, but this has to be tempered with the knowledge that it is not Begode’s responsibility for either the riding style or weather conditions chosen to ride in by all those using their products. I’m neither convinced that it is morally/ethically a great idea to sell on a wheel which you may have doubts about, it might be fair to inform the potential new owner as to the risks involved with the battery packs contained within the wheel, which would probably be reflected in the price that the wheel realised, but I feel it would be much better to either fit it with new and redesigned (safer) battery packs, or sell the unit minus the ‘risky’ battery packs, or with new BMS fitted to them. It seems there is a global shortage of cells at this point in time, maybe the fitting of new circuit protection to existing packs might be the path of least resistance (see what I did there!). Either way, I’ll carry on with my MSP HS and not take unnecessary or foolish risks, and have a fire blanket to cover the wheel when not in use. Thanks for your great work on this aspect, Adam, but maybe you could share with us your own outlook knowing what you know - will it change your riding style of your MSP, as you admit you’ve given it a pretty rigorous workout, and it is still here - maybe that is more about how good a rider you are, as much as how robust the wheel has been in the face of tough conditions and paths chosen, but I can understand that you may be moving away from Begode wheels more generally, and passing the potential for danger to the next rider, who anyway should have their own sense of acceptable risk level they are prepared to take on. My own take is if it passed the Wroong Waay testing grounds, then I as a (more conservative, touring type) rider should not have any greater risk of danger or problems, and though I hear your concerns about the battery pack designs on the older units, I temper that against my own much more conservative riding style. It may be that I consider replacing the older packs for newer, ‘designed for greater safety’ type packs if they become readily available, but considering the undoubtedly very high number of Begode wheels sold and still in daily use, the number of problems (of which the fuller background aspects have not been fully shared with the community) which have been recently flagged up must be a small overall percentage. I note too that other wheels have burned, probably owing to mechanical damage leading to short circuit, so the potential dangers are not exclusive to Begode, and the danger is inevitably built in to each and every cell and battery in all electric vehicles, so whilst it is good to hold Begode’s feet to the thermal runaway fire, we do need to remember that our mobile phone may just as easily catch fire if it takes a tumble. Thanks again, and let’s enjoy our great wheels without endangering ourselves, our wheels or others!
Fanboying Lol imagine hearing all about this and watching these videos and still going "I'll stick with my RS" lol. GL with all that. Looks like it was built by a blind 5 year old.
This is an very flawed take. These safety measures that were discussed are basic features that protect not just from user faults, but faults that can come from the factory. You cannot guarantee that the EUC rides safely, in ANY weather condition, without these features. Every single rider drops or crashes their wheel. Not all damage comes from just a hard riding style or bad weather. Not all short circuits come from water damage. Any of these can happen due to literally anything else like from a retailer shipping a faulty wheel. You are literally arguing that it's people's fault for their fucking house being burned down just because of a false assumption that "it's their responsbility" to somehow avoid any of these dangers. It's literally engineering 101 to understand your client and test your product so that they cannot ever damage it from use or from factory faults. In essence, it IS begode's responsibility so that at a bare minimum their houses aren't burned to the ground. And this isn't even going over the fact that the company is known for making wheels specifically for performance and high power, which your entire argument is completely based opposite of that. In hindsight, the issue with the fires WERE from a factory fault where the wheel didn't have the sufficient safety measures, resulting in the inferior performing M50LT battery cells discharging higher than its specs. It wasn't from the user "not taking responsibility."
Good home "noob" safety test is if after balance bateries by original gotway charger and turn EUC off and on app showw 100.8v this means battery is OK. Any sudent lost capacity mean some trouble and need check/investigate.🧨 My MSP 2500w have batery still great and in normal use is safe EUC to use no drama just use with brain and reponsibility.🤦🏻♀️ MSP etc. is still great powerfull machines what can make many smile on rider face. 👍🏻
BMS is one thing but why the short circuit happens at first place? Look that harness mess where power cables are going around sharp edges of heat sinks (that are conductive) without any restriction of movement.
I’m confused, if Wrong Way! says you’re doing it wrong, does that mean they’re doing it right? … but seriously thanks for all the work that you put into this, it’s very important and valuable information.
Regarding the waterproofing, iv commuted to work everyday on my MSP for over 1yr so regularly have to brave rain 🌧️ and it's never let me down but I do use a backpack rain cover over the top and sides so maybe that's a consideration for anyone that uses these machines as their only form of transportation
If you see this, can these problems be solved by replacing the battery packs with the improved ones/equivalent ones? (Like Samsung?) Or is the issue more in the wiring of the BMS itself and not just a battery pack issue? Could an electrician make changes to improve safety, or is that something you really don't want to mess with for safety/functionality of the wheel?
i did add a fuse on the power line of the charging port of my RS19 and my EXN because it is supposed to be there out of the factory... I use a 10amp slow blown !! But seriously selling your Gotway ?? you did made your own fear about Gotway wheel which will probably never happen to you and can happen even with a Kingsong, Inmmotion or Sherman.
I got two cheap Jetson bolts scooters last year on a holiday sales. One of the battery packs died on me when I was riding it. It would not take a charge. I shopped found a high Amp hour battery packs . I inspect and dissected the older battery packs it turned out the battery BMS overheated and melted some chips on it. Luckily it don’t set the cells on fire. The other scooter battery still working fine. The battery pack it comes with is a 36v 6ah tiny compared to EUC battery packs. Most scooter and ebikes I have the battery in a metal case or positioned on the vehicle were it is least likely to have impacts. The newer EUC models roll cages are a trend.
If two batteries packs connected in parallel and one of the pack's cell start to short out, than pack voltage starts to drop. Damaged pack with lower voltage starts to take charge from good pack. So already damaged pack starts to take charge and this could cause fire 🔥
Thanks ! Few days ago I found out that Titan scooter factory has about 150 empoyees, of which 10-20 are RND ( buying right bolts and ordering right motors ) , that is stated on their Alibaba profile. Kingsong states it has 300-500 employees, of which 30 are RND. Begode could have eaven less. So for real there are only few people in China, maybe like 10 who really knows how to design EUCs. What looks like a huge change in urban transportation in reality is powered by a small garage companies. And all those wierd things in personal electric vehicles is a result of such small companies.
Nice video, thank you! Did the exn HT you reviewed not long ago has got new battery packs with short circuit protection? Sorry for this silly question... I am struggling to follow as it is not my field at all but it would help tremendously, thank you.
i wouldn't agree that there are more gotway wheels (without "performance" prefix) pretty sure that the cheaper ones like KS14D are the best sellers (heard this from ecodrift CEO in chat)
@@omidel.i like antbms from cheap, also people say nice things about heltec. There are also many expensive like Orion, Rec Batrium and active bms like QNBBM. But I’m not sure which one will be best for you’re application it must be consulted and made by pro.
The way you said gotway didn't know what they did or the procedure for the tests, really gave me a chuckle and an immediate feeling that they bribed the tester from whatever agency is supposed to test the electrical products. Lol. It's the only thing that makes sense. Or one other possibility is that they sent a beefed up better more safety feature filled wheel in for the test and then made wheels without the protections in place for production in an effort to save money. Idk I'm just being silly
So I live in Seattle. I’ve been riding a first edition nikola since it came out. Over 5000 miles. It’s a beast in the rain or whatever. What wheel do you think is best as far as build quality and waterproofing?? I need a Jew one and your opinion would be huge. Thanks for all the time you put into these videos
Today exploded my motherboard in my RS19 Hs.... Brand new, i went with him just 40km....no rain, no crash, just went out of the door, switched on, began to run forwards and backwards, then black smoke and a explosion sound.... Beautyful day:(
Regarding the internal resistance test: packs are 2p so isn't your friend testing the IR on two cells in parallel? Then it would mean that the IR of a single cell is twice the value measured. Please correct me if I missed something.
it still amazes me that Begode haven't realised battery safety is a primary concern with EUC's. If they get their sh!t together with that they will sell more units. With the KS S20 coming soon they have some serious competition.
Any extra safety feature is a great thing to have. Regardless of manufacturer though a short circuit protection won't stop batteries catching fire 100 percent. Anything electrical has the potential to start a fire and the majority of house fires are caused by appliances. Maybe we should all sell our wheels...toasters and washing machines...I'm keeping my kettle tho...cant live with coffee😁 on a serious note. Great video and insight into battery construction. Feel free to send me your unwanted gotway wheels for your safety 👍

@@marksac5080 naah , don't think so. it is just for the clicks and for the money. I cannot beleive he might think Gotway gives a dime on this kind of stuff. Should be smart enough to realize his limited position. I really liked his way and his humor. So sad.
Great topic. I've had two GotWay/Begode EUCs, they both got shorted on their own in less than a year each. Their wheels are crazy dangerous and poorly built ; the last short circuit was for me the last time I ever look at a GotWay wheel forever, these guys are incompetents.

How impossible would it be to do a motor/guts swap? like remove one of the badass begode/gotway motors, swap the L-Hangers and Motor cables for maybe the V11 or Veterans L-hangers and cables.

@@mr_wrongway EUCs are illegal to ride in Deutschland yet they do service! that's crazy! I'd love something closer to Warsaw though. Preferrably something where I can visit and talk to an engineer in person.
This is amazing. Love the deep dive with a skilled engineer and lots of research. Could you perhaps continue with this and dispel one myth - "Inmotion wheels don't have battery\cell balancing". Do they really? Their BMS doesn't have a "balancing group" for each individual cell like in this video, but perhaps it balances cell groups or smth?
Battery builder here. That green cardboard/plastic stuff is called fishpaper. It's oil impregnated cardboard that's fire and abrasion resistance. I agree the corners are a weak point, if I were to build this battery I would use fiberboard then heat shrink around that.
On the subject of no short circuit protection, that can be fine as long as a fuse is used, but I don't see a single one. If the BMS was used for short circuit protection it may have a problem with surge loads and high speed cutout, it may risk the battery but under no circumstances do you want the wheel to just shut down at 50mph.
I disagree on the output pins being too close to each other. You would need full submersion to get enough current going between them to be a problem.
Regarding MOSFET burn segment. I'm not quite sure what he is getting at, those MOSFETs are small, but will sacrifice themselves in the event of short circuit. I don't see a problem here.
Oh, backtracking to mounting. Since the shell is plastic, even if the battery was worn through shrink wrap and cell wrap, it would not short. (But yes, water ingress is a concern in worn shrink wrap)
24:20, I think you mixed up some connectors here. From charge port to battery is an xt30, that's 30a max, not a concern since chargers top out at maybe 15a. From battery to controller (the bit you were holding) is xt60 for 60a. This is within spec, but I agree xt90 and thicker wire produces less heat and has greater current overhead.
Overall there are just a few things I would change, add fuse, add more abrasion resistance on the outside of the pack, wire the charge port to c-, and add a simple diode to keep the charge port cold when charger is not present.
These changes could be added as in-line adapters and packaged for users to easily install for maybe $20. Begode, hit me up, I've already got the design in my head.
FETs can go open circuit OR to be shorted thru. As well, i seen cases when all legs can.get shorted to each other. Aka Gate+drain+source.
@@pashko90 with the amount of power in that battery, any of those fets would be blown apart violently if they had a full drain, source, trigger short. Anything is a fuse given enough power.
@@pashko90 This was the case with my v11 controller that went south. 3 FETs completely shorted all gates.
@@marsrover001 Nope. Not allways a case.
What do you think about cell-level fuses? I think battery fires are way too common in EUCs. How would you prevent them?
It seems like a cell-level fuse guarantees that the battery won't catch fire since it will only allow moderate amounts of current, which won't heat the pack enough for a runaway, and the only risk left are since cells shorting themselves inside or with the casing.
Maybe using LFP or with better cooling, or temperature sensing?
Try taking apart KingSong battery packs (particularly pre-2021) and Veteran battery packs and notice how similar they are to Gotway.
Inmotion and Ninebot always took there batteries and packaging more serious. But if you want to be fair you should peak under the hood at KingSong battery packs (and maybe Veteran, consisting of ex-Gotway employees). Things might not look so rosy there too. I can tell you for a fact that the Sherman and most of the KingSong wheel battery packs are packaged similarly with the same susceptibility to abrasion against the shell plastic.
It's OK to dump on Gotway (I've done my fair share) but perhaps the same critical eye should be applied across the thousands of KingSong (14S, 16S, 18XL, etc) and Sherman wheels that have been produced. I may be surprised but I think there may be more similarities than not.
How can you in good conscience sell these dangerous wheels to other riders? ;-)
Totally agree, it doesn't make sense about concerning safety of a Begode owner but selling it to others would be ok. Review like this is great though for we understand the technical issue and make the manufacturer learn and improve their product. I know Begode/Gotway improve already their quality but it's not there yet but they are and same with other manufacturers. I know Adam will consider Begode wheel again for I could still remember the face of enjoyment when he used a crappy quality Begode wheel😉
I’m planning to check those other wheels too. However the hot charge port and no battery current limit/short circuit protection on Battery/BMS is a trait only at GotWay.
@@mr_wrongway Agree about the charge port. Not sure about the short circuit protection - if you go 3+ years back (a lot of those wheels are still out there). But yeah, if you do have the opportunity, please apply the same level of criticism (in this sense, good and bad) levied against Gotway to the other brands. You might end up only owning a V12 ;-)
the main difference is that battery configuration in gotway MSP is bad and also can cause battery leaks/fires
Very well said @ElectricUnicycles, but aaas always only bad things about the Gotway wheels
I vote Wrong Way for the European Commission For Wheel Safety president.
🤣 i will serve your needs 🤣✅
Great job Adam, really appreciate this deep-dive into battery safety.
Quick PSA - for those who are concerned with improving safety for their older Begode battery packs, you can always add a 30A inline fuse for each pack too (just make sure they are disconnected first of course).
Also for US riders, the vendor eWheels outsources their Begode battery pack assembly to LiTech and feature many safety improvements including imported Korean Samsung 50E cells, short detection/protection, inline fuses, voltage differential management for packs of unequal voltage, improved cell-holders for better survivability in the event of crash, and more. I wouldn't own an RS if it weren't for their safety investment efforts so I like to give them a shout-out when it's applicable.
this is dangerous and may cause cutouts because the mainboard doesn't take into account that there's fuses and will draw as much power as before. there should be oversized to decrease risk of a cutout, maybe 40 or 50amp IDK.
@@osimmac That's a good point, the maximum battery current limit set by the wheel's motor controller isn't really defined in a publicly published manual, at least from Begode wheels. Instead, we are assuming the Battery Current limit from the stated 2600W power limit for an RS as an example. That's 2600W/(3.2V LVC *24) = ~34A). 3.2V being roughly the Low Voltage Cutoff limit set by the motor controller.
Since eWheels uses a 30A battery fuse for their LiTech packs for the RS, it can be inferred that Begode is limiting the battery current draw as the pack voltage goes below 50% SoC. This is consistent with the riding experience limiting power as the battery level approaches 0% SoC. For other wheels that haven't included battery main wire fuses, you could try emailing the manufacturer for their recommendations on fuse size.
I agree with you though that over-sizing the fuse some probably wouldn't hurt if you don't know the exact Battery Current limit since it'd probably still break the circuit before thermal runaway and battery fire occurs in the event of a wire/connection short.
Thank you for addressing batteries and allowing conversational awareness to wheel maintenance in terms of battery safety. I learned a lot. Please next time address that the technology across all wheels are roughly the same and not isolated only to begode/gotway...you don't want people thinking that they can abuse an immotion/Sherman wheel expecting it to not catch in flames also.
Day 1 on EUC: Learn how to balance.
Day 400 on EUC: Making long form UA-cam videos explaining battery safety.
Charger port pins will explode when you stick fork in the charge port. My 3 year old boy did try it. After that I bough screw on charge port covers from Ali..
It was a very good video, thank you for this.
While it's interesting to look at one pack by itself, I think there is an inherent issue with the battery topology here with 2 packs directly wired in parallel.
And this topology can result in cell ignition in a specific case which we've seen happening:
1/ one or more damaged cell groups in pack B. Pack A is fine.
2/ the BMS can't keep pack B balanced.
3/ the damaged cell group self-discharges, reducing the voltage of pack B.
4/ healthy pack A doesn't self-discharge, so its voltage is higher than pack B. Now, it's charging pack B.
5/ as the process continues, damaged cell group keep to discharging and lose voltage while every other cell group in series has its voltage going up
6/ some cells groups in pack B end up beyond 4.2V
7/ ignition, fire.
And there is no mechanism to prevent that to happen in the BMS apparently. Or maybe only in some damaged BMS.
So it's very important to disconnect packs from the board and each other if one of the EUC doesn't charge to the max voltage anymore.
Otherwise this process will happen over two weeks, with a likely fire as a result.
That's why the packs communicate between eachother with those extra wires. When one pack cuts the charger, then the other pack has to, too. If not the healthy pack would charge the overvoltage pack through the parallel output.
When people make add-on packs for their gotways like 1600 to 2200wh, then they often forget this functionality = danger. The add-on pack could overcharge a bad pack in the system.
Bro loved this video. Was really amazing as always.
Good on you Adam, for talking straight - giving us the honest picture.
Another reason I love Ewheels. They had a third party put different and safer battery packs in the RS's before letting them go to the consumer. Also giving us a chance to choose different different battery options. Makes me feel a little better.
It does make some sense to have foam cushioning around the battery pack and allow some movement as this reduces the force experienced by the battery due to hitting pot holes or in a crash. This would be the equivalent of anti vibration mounts or crash protection, although in a simple form. The implementation could be better, for sure but it seems to me that the tight fit and use of double sided cushioning tape is sufficient to hold the units safely in place. Just my thoughts and feelings. A solid enclosure would lead to impact forces being transferred to the internals of each cell.
Always helpful!!💯👏👏
As we talking about safety...
Do you know the most powerful and expensive e scoot RION, use BMS ONLY for charging....😲😬😤
You pay almost 10000 euros and they don't put a good, big, BMS for discharge...
And we are taking almost a 100v... Made in USA...
From Greece 🇬🇷 with love and Respect!!
great content...thx for your afforts...
as a person, who working over 15yrs with electronics, i can say, i l'm sad to see that. "BMS" looks very dangerous for me. This is not a smart BMS, cheapest thing what they can insall. I do not understand, what was been a problem to add a fuse to Charge and discharge sides? as well lack of casing and fiberglass laminate sheets on this sides, at least? Imho battaries needs to be glued to wheel case as well. No super-all way thru, but they adre not suppose to rattle aroind as well. Ant bms or any other smart bms should be a good choies for wheel like so. I'm really interested to see what is going on inside of this wheels. :/
C+ port has diodes so it allows the current to flow in only one direction. If it was used it would prevent sparking, short circuits on the charge port, and allow parallel battery pack connections without one battery pack charging the other pack.
However those diodes have a finite current rating, and heat Dissipation before they burn out.
Fast charging would be really bad for those components.
Probably even charging when the batteries are discharged, and draw more current when charging.
Normally this depends on the diodes used.
On the GW BMS the C+ port is DEAD…you can see arrows on the BMS….there SHOULD be the diode, but there is none.
I have build packs with those GW BMS and i used the C+ port….the pack doesnt even charge then. I had to resold the c+ wire to b+ as that is the only way charging works here. (or one can fill the arrows with solder, but then the chargeport STILL would be hot)
@@ullle66 Oh Gotway! SO it's PCB print with no soldered diodes. And probably those would have to be 5A diodes which are quite fat...
Good video Adam. What conectors are used by other EUC manufacturers? XT60 are rated to 60A continous, not 30A. So 3 battery packs 60A*3=180A. More than enought. Easies and chepest way to fix the short circuit issue is to add fuse to each battery pack, as well as for charging port. But sure it is good to point all the weakness in the video. Hope it give Begode strong signal to improve.
Thank You very much, I still have to approach the EUCs world, but that's my intention :) so, I extremely appreciate all of Your efforts on doing such videos, therefore all of the community can make proper choices and be safer. Thank You (from Italy :)
Another great video, and the fact you are selling up is amazing. It will lead to Gotway sales dropping faster and faster, as I have said before Gotway will only change and develop if they are making a loss. To be honest I think that it is too late.... at the moment if you want a performance wheel you have the V12 and KS20 on the way, and within the next two years there will no zero reason to by a Gotway. I only hope the both Kingsong and Inmotion produce a 10" and a 14" wheel both massively important wheels. Tear downs by both you and Marty leave nothing to the imagination.
So good to see reviews regarding the safety of all this electric gear. This is still the wild west as far as manufacturing this stuff is concerned and companies need to know that if they cut corners and build potentially dangerous products, they are going to get exposed.
THANK YOU.
I think your words and actions are justified. Hopefully others follow suit. Safety should always come first and now KS/Leaper/InMo are bringing us performance wheels with safety and proper engineering :D
i can't believe the sloppy work of their battery pack, thank you for high lighting this
Well done for putting some facts into the frame. So much suspicion and hearsay re. Begode wheels, the EUC community needed his video! 👍
Always love seeing the intro shot of you ripping around the corner.
There are certified battery specialists around, who make up custom battery packs from scratch. I know an RS19 owner who's looking at having 2 x 900wh Molicell battery packs made up. I assume that could include a more advanced, better wired BMS board & maybe better protective covers (if requested?). Considering the same for my 2019 Nik+. Possibly cheaper than a new wheel? 🤔
Cheaper than a new wheel, perhaps….depending!
2 x 48cells Molicell would not be 1800wh…it would be about 2 x 740wh. When you make those packs yourself you probably get cheaper, as the material is about 500euro cells plus 200euro BMSs. But letting a pro do it? depends on his work costs
thanks dear...
One job I had was doing qual testing for life safety and security devices.
This is why standards exist and if your product doesn't conform to them you may find yourself not only restricted from those markets where those standards apply but also under investigation if enough dangerous incidents are observed in a period of time. If your product ends up harming someone, in the US the Consumer Product Safety Commission may come knocking and not only does that just clobber your delivery schedules it costs you a lot of money to make them happy again, so you can return to shipping to the US.
If they're smart, they'll hire a couple very competent engineers, have a fast recall, cross ship people their replacement wheels/parts, designate regional shops that can help people perform recall services if they don't feel comfortable doing it by themselves, about the same thing Toyota had to do when the Lexus unintended acceleration thing was happening. As soon as it was publicized, they got on it and it got resolved (the government was watching). They need to do same here. It's the right thing to do anyhow, just do the right thing right is all. :-)
Very well-analyzed material and the market situation
If you want to have two battery packs in parallel 'same port BMS' is the correct way to go. But - Usually there is a protection diode and charging fuse.
If you live in an apartment building, and you buy a begode. Is that even responsible at this point? If a neighbor in my building buys a begote, don't know how i would feel. Am I overreacting?
Hm for most cases the wheel is fine but in certain conditions it might become dangerous…I don’t really know
I find myself putting my RS in my garage that's surrounded by cement cuz I'm afraid of a fire breaking out 🤷🏾♂️
Thats - in MY view- a bit overreacting. The reported Short circuits dont happen out of thin air!
Control charging (dont leave it alone), plug off when ready with charging, and then while the wheel just standing their there is pretty much no pssibility of a short happening. The most GW fires still come from abusing the wheel/battery……so dont do that, too. Drive with „sense“.
I for my part have a smoke detector directly over my wheels, and they are near the door……thats the best safety practices i can imagine.
And be aware: a venting battery -just because of ONE cell becoming chemical bad - in the end that can happen on EVERY brand EUC.
That is just THAT EXTREMLY seldom…..i dont even have that in my mond when thinking about battery safety. One who is THAT concerned….should nt carry a cell phone in his pocket, too!
@@mr_wrongway If you don't know. I have no chance 🤣. The last videos are getting better and better. Thanks
@@ullle66 I'm not going to pretend I understand much about how, and why the fires happened. I hope you are right! Just don't want something bad to happen in an apartment building for example, and get us all banned for the city's and buildings. You know, they, the news, never differentiate the brands, it's going to be like "EUC dangerous" not begode.
Thanks a lot for taking the time to do such a great video.
You got my like (not often given)
I’ve bought an RS less than a week ago :( Now I’m afraid to ride it…
Someone wrote Another reason I love Ewheels. They had a third party put different and safer battery packs in the RS's before letting them go to the consumer. Also giving us a chance to choose different different battery options. Makes me feel a little better.
Nothing will save you if cell itself has short circuit inside. Plastic housing of Inmotion wheel is also useless in this case :-).
Thanks Adam. Very very usefull info.
The takeaway seems to include: use these wheels in the wrooong waaay at your own risk and responsibility! It should maybe be borne in mind (in fairness to Begode) that the way you have ridden your own personal MSP could be shown as a very strong test of what the wheel’s battery packs have managed to withstand, and nobody (including Begode) have at any time endorsed either riding in wet conditions, nor riding in ways that could conceivably cause damage to the wheel or the battery packs inside: in essence, if you risk dropping or crashing your wheel, or damaging it by riding in any type of ‘hard riding style’, then you are personally risking a short circuit or fire.
I absolutely get that the battery packs are not well designed in terms of passive safety, and indeed it would be good to see a redesign to address this potential danger, but this has to be tempered with the knowledge that it is not Begode’s responsibility for either the riding style or weather conditions chosen to ride in by all those using their products. I’m neither convinced that it is morally/ethically a great idea to sell on a wheel which you may have doubts about, it might be fair to inform the potential new owner as to the risks involved with the battery packs contained within the wheel, which would probably be reflected in the price that the wheel realised, but I feel it would be much better to either fit it with new and redesigned (safer) battery packs, or sell the unit minus the ‘risky’ battery packs, or with new BMS fitted to them. It seems there is a global shortage of cells at this point in time, maybe the fitting of new circuit protection to existing packs might be the path of least resistance (see what I did there!).
Either way, I’ll carry on with my MSP HS and not take unnecessary or foolish risks, and have a fire blanket to cover the wheel when not in use. Thanks for your great work on this aspect, Adam, but maybe you could share with us your own outlook knowing what you know - will it change your riding style of your MSP, as you admit you’ve given it a pretty rigorous workout, and it is still here - maybe that is more about how good a rider you are, as much as how robust the wheel has been in the face of tough conditions and paths chosen, but I can understand that you may be moving away from Begode wheels more generally, and passing the potential for danger to the next rider, who anyway should have their own sense of acceptable risk level they are prepared to take on. My own take is if it passed the Wroong Waay testing grounds, then I as a (more conservative, touring type) rider should not have any greater risk of danger or problems, and though I hear your concerns about the battery pack designs on the older units, I temper that against my own much more conservative riding style. It may be that I consider replacing the older packs for newer, ‘designed for greater safety’ type packs if they become readily available, but considering the undoubtedly very high number of Begode wheels sold and still in daily use, the number of problems (of which the fuller background aspects have not been fully shared with the community) which have been recently flagged up must be a small overall percentage. I note too that other wheels have burned, probably owing to mechanical damage leading to short circuit, so the potential dangers are not exclusive to Begode, and the danger is inevitably built in to each and every cell and battery in all electric vehicles, so whilst it is good to hold Begode’s feet to the thermal runaway fire, we do need to remember that our mobile phone may just as easily catch fire if it takes a tumble.
Thanks again, and let’s enjoy our great wheels without endangering ourselves, our wheels or others!
Fanboying
Lol imagine hearing all about this and watching these videos and still going
"I'll stick with my RS" lol.
GL with all that. Looks like it was built by a blind 5 year old.
Thank you for that post. I could not agree more. Adam has lost his objectivity when talking about EUC's.
This is an very flawed take. These safety measures that were discussed are basic features that protect not just from user faults, but faults that can come from the factory. You cannot guarantee that the EUC rides safely, in ANY weather condition, without these features. Every single rider drops or crashes their wheel. Not all damage comes from just a hard riding style or bad weather. Not all short circuits come from water damage. Any of these can happen due to literally anything else like from a retailer shipping a faulty wheel.
You are literally arguing that it's people's fault for their fucking house being burned down just because of a false assumption that "it's their responsbility" to somehow avoid any of these dangers. It's literally engineering 101 to understand your client and test your product so that they cannot ever damage it from use or from factory faults. In essence, it IS begode's responsibility so that at a bare minimum their houses aren't burned to the ground. And this isn't even going over the fact that the company is known for making wheels specifically for performance and high power, which your entire argument is completely based opposite of that.
In hindsight, the issue with the fires WERE from a factory fault where the wheel didn't have the sufficient safety measures, resulting in the inferior performing M50LT battery cells discharging higher than its specs. It wasn't from the user "not taking responsibility."
Good home "noob" safety test is if after balance bateries by original gotway charger and turn EUC off and on app showw 100.8v this means battery is OK.
Any sudent lost capacity mean some trouble and need check/investigate.🧨
My MSP 2500w have batery still great and in normal use is safe EUC to use no drama just use with brain and reponsibility.🤦🏻♀️
MSP etc. is still great powerfull machines what can make many smile on rider face.
👍🏻
What.
@@tadeuszzielinski8798 what what?
Thank you Adam!
BMS is one thing but why the short circuit happens at first place? Look that harness mess where power cables are going around sharp edges of heat sinks (that are conductive) without any restriction of movement.
Here we are again :) ⚡️❤️ good decision with selling this “fire catchers” 👏
I’m confused, if Wrong Way! says you’re doing it wrong, does that mean they’re doing it right?
… but seriously thanks for all the work that you put into this, it’s very important and valuable information.
Regarding the waterproofing, iv commuted to work everyday on my MSP for over 1yr so regularly have to brave rain 🌧️ and it's never let me down but I do use a backpack rain cover over the top and sides so maybe that's a consideration for anyone that uses these machines as their only form of transportation
I waterproofed my V8F, but always have a plastic bag in my backpack just in case.
If you see this, can these problems be solved by replacing the battery packs with the improved ones/equivalent ones? (Like Samsung?) Or is the issue more in the wiring of the BMS itself and not just a battery pack issue? Could an electrician make changes to improve safety, or is that something you really don't want to mess with for safety/functionality of the wheel?
Very good & very informative video! Thank you!
i did add a fuse on the power line of the charging port of my RS19 and my EXN because it is supposed to be there out of the factory... I use a 10amp slow blown !! But seriously selling your Gotway ?? you did made your own fear about Gotway wheel which will probably never happen to you and can happen even with a Kingsong, Inmmotion or Sherman.
Very informative. Excellent. Thanks.
I like how the metal zipper is dangling near the BMS )
Professor has started his lecture... Class, listen!
How good are electric scooter batteries? Would be interested in a video on them. Many Thanks!
I got two cheap Jetson bolts scooters last year on a holiday sales. One of the battery packs died on me when I was riding it. It would not take a charge. I shopped found a high Amp hour battery packs . I inspect and dissected the older battery packs it turned out the battery BMS overheated and melted some chips on it. Luckily it don’t set the cells on fire. The other scooter battery still working fine. The battery pack it comes with is a 36v 6ah tiny compared to EUC battery packs. Most scooter and ebikes I have the battery in a metal case or positioned on the vehicle were it is least likely to have impacts. The newer EUC models roll cages are a trend.
If two batteries packs connected in parallel and one of the pack's cell start to short out, than pack voltage starts to drop. Damaged pack with lower voltage starts to take charge from good pack. So already damaged pack starts to take charge and this could cause fire 🔥
possibly at home? where else can you store it?
What type of cells did inmotion say are in the V12?
great and interesting video. is rs19 safer?
Thanks ! Few days ago I found out that Titan scooter factory has about 150 empoyees, of which 10-20 are RND ( buying right bolts and ordering right motors ) , that is stated on their Alibaba profile. Kingsong states it has 300-500 employees, of which 30 are RND. Begode could have eaven less. So for real there are only few people in China, maybe like 10 who really knows how to design EUCs. What looks like a huge change in urban transportation in reality is powered by a small garage companies. And all those wierd things in personal electric vehicles is a result of such small companies.
Thanks Adam. A recall from a Chinese company? LOL. Now you're a comedian? A man of many talents.
You said there is no communication with the motherboard from the BMS, where is the extra cables (black connector) going?
Black connector is communicating between batteries
Thanks Adams, top Info
Nice video, thank you!
Did the exn HT you reviewed not long ago has got new battery packs with short circuit protection?
Sorry for this silly question... I am struggling to follow as it is not my field at all but it would help tremendously, thank you.
Yes sir this exn was different however it still had a “hot” charge port.

Who knows maybe videos like this will hurt gotway revenue enough that they implement better safety practices.
i wouldn't agree that there are more gotway wheels (without "performance" prefix)
pretty sure that the cheaper ones like KS14D are the best sellers (heard this from ecodrift CEO in chat)
Is it possible to open a pack and change the begode Bms with Dali or something better?
Yes but it’s a big hassle and you’d need a professional to do that
Easiest way is to add fuse to each battery pack. Normal BMS is not design for EUC and can make more harm than good.
Dali are not that good, I’m not saying bad, but still cheap passive one.

Good awareness vid for the community.
The way you said gotway didn't know what they did or the procedure for the tests, really gave me a chuckle and an immediate feeling that they bribed the tester from whatever agency is supposed to test the electrical products. Lol. It's the only thing that makes sense. Or one other possibility is that they sent a beefed up better more safety feature filled wheel in for the test and then made wheels without the protections in place for production in an effort to save money.

Thank you for sharing this content
Regarding the internal resistance test: packs are 2p so isn't your friend testing the IR on two cells in parallel?
Then it would mean that the IR of a single cell is twice the value measured.
Please correct me if I missed something.

Now.. please do a kingsong battery safety review.
Thanks again for the Shout Out! Great video, now ;-)
nice to see this plain honesty from youtubers keep it up. Also yeah Murphy Law specially for gotway wheels
it still amazes me that Begode haven't realised battery safety is a primary concern with EUC's. If they get their sh!t together with that they will sell more units. With the KS S20 coming soon they have some serious competition.
So that means my Monster 100v 1845wh and tesla v2 can burst into flames anytime?
I have a MCM5 v2 purchased in September, do you know if these wheels came with the short circuit protection?
Well i guess ill be selling my Tesla and MSX in the near future.
Any extra safety feature is a great thing to have. Regardless of manufacturer though a short circuit protection won't stop batteries catching fire 100 percent. Anything electrical has the potential to start a fire and the majority of house fires are caused by appliances. Maybe we should all sell our wheels...toasters and washing machines...I'm keeping my kettle tho...cant live with coffee😁 on a serious note. Great video and insight into battery construction.

I've had two GotWay/Begode EUCs, they both got shorted on their own in less than a year each. Their wheels are crazy dangerous and poorly built ; the last short circuit was for me the last time I ever look at a GotWay wheel forever, these guys are incompetents.

good
This is amazing. Love the deep dive with a skilled engineer and lots of research.
Could you perhaps continue with this and dispel one myth - "Inmotion wheels don't have battery\cell balancing". Do they really? Their BMS doesn't have a "balancing group" for each individual cell like in this video, but perhaps it balances cell groups or smth?
That a myth! Sure IM has individuell cell balancing!
I did à tear down on a V10f the battery is well protected and have a well protected BMS
Wow, glad I didn't buy a Begode...
Nice shirt! Do you play video games? Any favourites? :D
Thank you! I got the shirt from my GF :) I don’t play games anymore because I get addicted too quickly…
