EUC

  1. Electric unicycle online communities have been vigorously discussing best practices for EUC storage in light of recent reports of wheels bursting into flames. Fire blankets being the most widely discussed method of protection. Begode even issued a letter to help alleviate public fear. YouTubers sponsored by eWheels began making calls to temporarily boycott Begode until the company addressed its quality control issues. However, Begode’s efforts weren’t satisfactory to eWheels owner Jason McNeil. According to Marty Backe, who runs the fourth most viewed YouTube channel about EUC’s in the U.
  2. Hey I'm an electronics engineer! My EUC has an 800Wh battery, and I have never used more than 50% in a single trip. I love going to coffee shops and parks to get work done, so why not tap into that enormous potential to power my laptop all day? That'd cover me for more than 8 hours, even on ridiculous workloads like VR gaming. So I bought a cheap power supply that can drive my laptop using 30-90V, which is more than the range of the battery pack. I'm using an MCM5, and I've found that charger pins 1 and 2 go directly to the battery for charging, but it appears that something (p
  3. Hi guys, Do any of you know the Continuous Current, and the Peak Discharge on the Tesla & Mten 3 batteries? It's my understanding that for each unit there are two batteries and they have a 84.7 Voltage. Thanks everyone!
  4. hi everyone, I got this battery and would be grateful if anyone could tell me where or what the extra black connecter is used for.
  5. I used my 41mb of my attachment limit, sorry here the link to photo tutorial for disassemble battery (Im not making money with my blog , there's only a google cookie inside Update June 02 2021 https://sites.google.com/view/mini-j-world/home/mini-tech-s-pro/parts-repairs/battery#h.p_EEG4HWiTF_7F
  6. Hi all, I have ordered 14D controller and the battery packs from ewheels. But when I try to install, the motor is not getting engaged. The controller is beeping. Also I checked the motor connection cables several times. Attaching the video regarding the same. Any help is highly appreciated. KS 14D.mp4 Adding another video.... KS 14d_2.mp4
  7. Hello, I bought my Segway Mini Plus the beginning of this year in US. I was working there, however I live in Chile. To take it back on the airplane, I took it aparat - stand board with wheels - direction handle - battery pack The Battery Pack i took appart in single Litium Batteries and then spot welded it at home together. Everything worked fine. However last week I washed it with my Kaercher Hydro Pressure Cleaner, and I think I screwed up the boards, that handle the Battery Charging. Does anybody know where to get those as spare parts? Michael
  8. I'd like to hope to see some of these ~500wh/kg ~1000wh/L ~1000cycle batteries find their way into EUCs by 2025. That would be sweet .. to about double the battery kwh of a EUC without an increase in weight. Expecting cost will probably be pretty 'orbital' https://sionpower.com/products/ https://sionpower.com/2020/sion-power-demonstrates-key-electric-vehicle-ev-battery-performance-requirements-in-its-lithium-metal-rechargeable-battery-cell-technology-2/ In the mean time .. I'd like to just get my hands on some 'test' samples
  9. Hi, I wonder if someone can help me. I have a hooverboard (from China) and it's always worked perfectly, though we've not used it much. However, I have encountered a problem..... the battery does not retain a charge, the first thing I noticed was that after charging the battery only lasted a very short time (now I think that there was no charge applied and the battery was just depleting more each time); if I plug in the charger, I get the correct flashing amber light (at least I think it's correct); but no charge is retained; now, if I unplug the charger the hover
  10. Hey everyone, I have a ninebot z10. Was my first and is my only wheel. I know many people experienced issues with their z10s. But i never had a real issue with mine. Unfortunately i have not ridden in a long time due to life being too busy. I tried to charge my wheel up the other day amd it doesn't respond. The charger light stays green. I tried disconnecting the battery but that didnt work. I tried charging the battery directly with a cable connected to the charger. But that hasn't work. I am going to retry this with different wires because they might not be connecting. Doe
  11. I took a screen shot of the battery percentage on both apps. EUC World showed 37% and Darknessbot showed 54%. That’s a big difference. Anyone know why this would be the case?
  12. My charge-and-ride backpack: Conclusion: This was a pain to build. It's useful now that it's complete. A 58.8V (14s) pack would have been better... But I should have just purchased the ~$800 KS-Power device. The good: It adds about 20 miles of range, in my typical on-road riding. It also lets me ride at ~30mph for 60 minutes straight, something that I couldn't do previously because of the slowly decreasing EUC voltage. Efficient: Since it's the same pack voltage as my 84V EUC, the boost convert
  13. I bought an IPS i5 245WH on 9/5/2018. I have been riding it since and enjoyed it very much! A few weeks ago, the wheel starts to beep constantly. And later on I discovered whenever I charge it, the charging light turned red and immediately turned back to green. It seemed the battery was no longer charging and low battery caused it to beep constantly. I contacted the manufacturer in China and showed them all the settings and voltages from the Android App. They said the battery cells are good, maybe just the connector was loose. I tried juggle the connector and no use. Today, the battery
  14. I have a Ninebot S that I have added M4M hybrid tires. I take it to the golf course and barely can make 18 holes with it and relatively flat courses, although I usually can make it. But it is surprisingly gets pretty darn close to depleting the battery. Last week, I barely got back to my car with the device beeping at me because I was at 7% battery left. I'm hoping if I swap out the stock battery (236 Wh / 4300mAh) with a MiniPro pre-2018 battery (310 Wh / 5700mAh) that this would now comfortably get me through a round of golf. I have read a few places that I would need to use the bigger
  15. The voltage on my monster battery pack is too low to charge with the included charger, is there any hope for the pack or is it basically trash? 😬
  16. Has anyone ever had a battery with a voltage reading too low to charge with the included charger? If so what did you do about it?
  17. I need help identifying a part or part number. I acctdently damaged the connector that connects the round batter Ninebot Model NEB1002-H to the control board. Here is the image of the part. https://www.facebook.com/photo/?fbid=178876496920532&set=a.178876516920530 If you could please email me sinor2018@gmail.com that would be great. I tried google image search to no avail. I hooked the battery up without that cable and got error message.

  21. Hi, does anyone knows what specs are the standard bms for the 20s from gotway? I'm looking specifically at the max current rating that I need for an extra battery pack. thank you
  22. I'm having a similar problem described in these threads. see context for all the details i have https://forum.electricunicycle.org/topic/7670-ks16s-stops-charging-at-76/ https://forum.electricunicycle.org/topic/15150-ks14s-stops-charging-before-100/ Unfortunaety i'm going to mexico for 10 days and wont' be able to troubleshoot. I've emailed Jason from ewheels, and he says it should be safe to ride but be more careful at lower voltage. I'm concerned my packs will become more out of balance or some of the cells might be charging beyond 4.2v to make up for a possibly bad cell
  23. Dear all, My Inmotion V5+ does not seem to charge full to 100% as indicated on the app anymore. While the light from the adapter (that rectagular block thing) switches from red to green, when I connect to the app the percentage is always only 90 something, never 100%. Moreover, when I connect to the app while charging the V5+, there seems to be no indication on the app to say that it is indeed charging. Any help? TIA
  24. Hey guys, just wanted to put this out there as my experience with a recent purchase of a Segway MiniLite. I purchased a new MiniLite from Pharmaprix/Shoppers Drug Mart in early December (2 weeks ago), and was excited to gift it to my brother for Christmas. However not wanting to give him a dud, I opened it up (kept all the plastic on it) and tried to turn it on (by pressing the ON button). Nothing happened. I tried to plug it in to the charger and received a green light on the charger. After several hours I attempted to turn on the MiniLite to no avail. As others have done, I
  25. Hello everybody. I want to clear my brain of some worries and listen to input about this from other riders who may have more knowledge on this than me. On a group ride in late Feb, I rode about 45km and returned home with 35% battery remaining. Pretty good for a day spent going up long hills as well as down them, in temps between 4-7C Just recently after that, I decided to get some Silicone and made a custom gasket for my sidepanels. Just as an insurance against any future water ingress. There's obviously been some water in my color LED's because on the left side they spaz out, even whe
