    Explosion

    Dear All EUCers, This is my first post on the forum but hope this helps as a warning to all EUC riders, especially to those who purchased E+ in or before 2015 through a reseller, because apparently Segway will not care or investigate further into the case if it's not bought directly through them. Also, simply because Ninebot product lines have obtained UL2272 certification, this does not guarantee that it will not explode. I have been writing the similar content over and over, this time I will copy and paste what I sent to Segway last Wednesday (minor edits due to Personally Identifiable Information) to save some time... Thank you, Andy https://drive.google.com/file/d/1HZY4f_JJRP7TIymvoEtlwnwjcESeQbi_ ------- ------- Dear Segway, This is my second attempt to reach out to you. Hope you can respond as soon as possible. Below is the original text I submitted on Sunday through your technical support page. Please read and respond as soon as you can (screenshot of pictures below). Hope to hear from you soon, Andy -- Hi, I have been riding Ninebot One E+ to work everyday on it for the past 3.5 years in San Francisco Bay Area, and even take it to nearby beaches such as Half Moon Bay, Monterey or Big Sur when it's sunny here in Northern California. Today has been a very traumatizing and sad day for me as I lost my beloved 3 year old Ninebot One E+. Ninebot One was more than a leisurely device, but a major companion allowing me to live a smaller carbon footprint (don't have a car) lifestyle, my main mode of transportation and identity among my family, friends and neighbors. When it suddenly exploded and burnt in a vicious fire during non-energized state, I was luckily to be more than 5 feet away from it. I was extremely lucky and no one was hurt. This could have been much, much worse. I could have lost my right leg, I could have died or the entire apartment could have burnt down causing even more casualties. Please read on. It was a typical weekend--sleeping in and getting up pretty late. At around 11 AM, I took shower and had a breakfast. At around 11:45, I started hearing popping noise. Thinking it was coming from outside, I opened the door and saw but there was nothing. A few more minutes later, another pop. Then every minute or two, I started hearing the noise at a regular cadence. Then, my sensors became much more sensitive and started smelling something acrid. This is when I realized the sound--and potentially the smell too--was coming from my beloved 3 year long friend. My instinct now as sharp as blade, I knew I needed to do so something. 12:01PM (film available) 1) Before making any action, I felt strong need to document every single detail. I filmed 36-second long video to capture one more "pop" sound. 2) Being super safe, I first went to the power strip and turned it off, 3) then unplugged the cord from the power strip, 4) and then unplugged from the unit. ~12:03PM 5) I raised the handle bar and tried to grab it from the end of the handle bar as usual, but I didn't. 6) Instead, I grabbed the center of the handle and supported with my left hand under the foot pedal so I don't accidentally agitate the unit too much and trigger it to explode. (VERY RISKY) 7) (STILL FEELING VERY RISKY) I took it outside and leaned it against the immediate exterior wall I was able to get access to. ~12:05PM 8) then I started thinking about what to do (take it in? repair myself? don't ride and let it sit for a few days? disassemble and recycle properly? ~12:09PM 9) before I finished my thoughts--and my front door still wide open, I heard a bam and a small fire. Then one or two more KABOOMs with much larger fire, creating fizzing sound and burning everything the battery was wrapped in violently. This lasted for a minute. 12:10PM (photo available) 10) when the fire was weakening, the property manager luckily was outside and who saw this happening ran towards me to aid and grabbed the fire extinguisher. I knew I had to document this. I am thankful that there was no bodily injury to anyone involved in this incident; however, I'm still scared and extremely frustrated due to the life-threatening and traumatizing experience. Also, because of inhalation of toxic fluoride gases from burning Li-ion batteries, I am in distress and deeply concerned about my health. https://www.atsdr.cdc.gov/MMG/MMG.asp?id=1142&tid=250 For that reason, I am having to evacuate the unit and arrange temporary stay which is costly and inconvenient. Please give me a call at 510 634 9390 ASAP. I would like to share more in detail and discuss further. Thank you, Andy one more image
  2. Hi, I am new to EUCs but have done some extensive research on them and am purchasing for my first wheel quite soon. I would like some input on whether or not there are incidents of EUC explosions and fire. I know hoverboards have been banned on college campuses around the US due to these incidents. Bans aside, I would like to know the frequency of such incidents compared to those of hoverboards. I know that the consumer population for hoverboards is/was larger than that of the EUC, and if that isn't the case, then there is much more widespread news coverage of hoverboard fire accidents. Any thoughts? Thanks!
  3. Are the Inmotion devices such as the V5F and V8 UL certified? Have there ever been any reports of fires or battery explosions with their products? I've been trying to decide between a V5F+ and a Segway S1 which is UL 2272 certified, but the Inmotion website doesn't mention any sort of safety certifications. The V5F definitely has preferable specs to me, but I'm concerned about safety after seeing so many reports of hoverboard fires.
  4. Hi. I was in the process of rebuilding my 340wh Lhotz, adding a standard 180wh battery with its own BMS to have 520wh total. I accidentally shorted the charge wires with catastrophic result. Batterypack started to smoke, the plastic melted and the charge wires started to melt. Luckily the chargewires didnt melt completely before I managed to separate the short, if i hadn't I'm sure a batteryfire was imminent. So now to my question, doesn't all BMS have short protection on the charge wires? To me it's mental not to have. It's just as dangerous as not having it on the output wires. How is it that I could draw this high current from the charge wire anyhow? feels like a faulty design. Is this standard manufacturing practice or is this BMS a really bad one? Batterypack in question. https://m.aliexpress.com/s/item/32686348373.html?trace=wwwdetail2mobilesitedetail&productId=32686348373&productSubject=32686348373&shortkey=VJ77Vfia&addresstype=600
  5. Please take a look at the product demonstration here With hoverboard fires being a huge concern for some people, all of us here at SegYourWay have teamed up to bring a simple, yet effective Fire Resistant Hoverboag. This bag has been designed to contain any explosion that a hoverboard can produce. This bag is also layered with a special carbon fiber coating which helps the bag to maintain its shape during an explosion or fire. The Hoverbag can be used for charging, and storing of all 6.5 inch hoverboards. Arrives in 3-5 business days! Instructions: Plug in the hoverboard and place one end of the hoverboard in the Hoverbag. Then hold the Hoverbag while pushing the hoverboard into the bag until the board reaches the back of the Hoverbag. Once reached, grab both ends of the Velco strip, pull tight (apart), and seal. It is important that the Velcro has a flush seal to get full potential of the Hoverbag. Made in the USA Size: 35" long and 16" wide Equipped with a wide heavy duty Velcro strip Open charger wholes on both sides for user preference Light weight and portable For a video demonstration visit https://www.youtube.com/watch?v=Q0WvEJXB8Ao Have an 8 or 10 inch hoverboard? Send us an email to pre-order the new upcoming bigger sized Hoverbags.
  6. So, I bought this really cheap hoverboard ($80) on Aliexpress. Can someone tell me if it is reliable, i.e will it explode? Also considering its so cheap im worried that it won't show up. Any thoughts? This is it: http://www.aliexpress.com/item/2-Wheel-Balancing-Scooter-Smart-Electric-Balance-Scooter-Self-Unicycle-Balance-Board-Drift-Scooter-hoverboard-Outdoor/32586044909.html
  7. There's a posting on Craigslist offering an aftermarket service to service pre-owned boards to make them 85% safer from fire through a $50 retro-fit. I wrote to them asking what exactly they're doing for $50 and why it's 85% less likely to catch fire, but received a non-discript reply. http://philadelphia.craigslist.org/ele/5356419116.html Here's a snip of what they responded via email: "We have developed a way to reduce the heat that is generated by the battery when in use and when charging. We also check to make sure the battery has falt protection but even with this protection the battery still has the potential to ignite and explode." Anyone know what this is referring to? Are there add-on parts/fuses that can regulate the battery/internal workings?

    Is this a safe board?

    I really want to buy a hoverboard for Christmas but I have heard that a lot of brands don't use safe batteries and result in the board catching fire. I have done research for almost days trying to find a safe board to get. The 1 im looking at currently has a 36V,4.4ah Samsung Li-ion battery. Can someone please tell me if thats a safe battery and it for sure wont catch on fire? Thanks!
