Popular Post Cress Posted July 4, 2022 Popular Post Share Posted July 4, 2022 (edited) I like the video - above - by e-Rides and I expect e-rides does very good work with the board-swap. Inmotion should think about how the V12 got to this point, a good design that will find lots of buyers has to be recalled because no knowledgeable person at Inmotion spoke up about a critical inappropriate component. Successful manufacturers incorporate review process and eliminate errors. Technical reviews save money. Technical review would have avoided the mess with swapping a motor controller and Inmotion wouldn't have the several, helpful videos about their motor controller viewed for years. Until and unless EUC Manufacturers learn why manufacturers of other, technical products have multiple points of review from design through production EUC mistakes will be interesting to watch, difficult to predict, and will not stop happening. You've got to wonder, 'What's next?' Edited July 4, 2022 by Cress /, space 5 Quote Link to comment Share on other sites More sharing options...
Paul g Posted July 4, 2022 Share Posted July 4, 2022 (edited) Nice: @Inmotion Global delivering boards without grinding low the pins so the chance of shortcut is high (min. 17:30). This might be one of the possible reasons why @adrianqbs’ and PET UK shortcuts happened! Thank you Kevin e-rides! I’m so grateful for the knowledge you share with us! You rock! 🤘🤘🤘 Edited July 4, 2022 by Paul g 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Paul g Posted July 4, 2022 Popular Post Share Posted July 4, 2022 This brings us again to the quality issues with InMotion! In no case is acceptable to send the boards to your costumers like that, when you must have known from your own assembly processes that you needed to grind them short. 3 1 Quote Link to comment Share on other sites More sharing options...

None of the V12 board replacements I've completed so far have had longer joints like this. I suspect quality control is under the pump right now since we are still not receiving the number of boards we require in a reasonable turnaround. 4 1 Quote Link to comment Share on other sites More sharing options...

One with very-very long handle for my aquarium - feeding. And very similar like these in video - they are very useful if you need to "lock" something in place while holding... Pff get on my level. 2 Quote Link to comment Share on other sites More sharing options...

It’s super easy to follow, but that is not the point, to my mind it will be quite off putting to a number of existing owners, let alone new owners with less experience or confidence. Not being a user of this wheel it is merely of passing interest to myself, but I got the firm impression that i) it is quite time consuming, ii) possibly a little stressful for those doing the changeover, and iii) quite possible to make the new board inoperable by a moment of incaution, whether grinding or cutting away excess solder, or reassembling the whole - in my view not perhaps an ideal starting point for a recently-invested-in new wheel owner to find themselves in. 3 Quote Link to comment Share on other sites More sharing options...
vBlitz Posted July 5, 2022 Share Posted July 5, 2022 Had a cutout yesterday, I filled the form. Here's a summary: V12 HS batch 2, original board dry flat dirt trail 40/45kph was at 74% battery at the start was at 59% battery at the time of the crash casual cruising, no strong acceleration rode about 10km before it happened the wheel has a total of 4250km (in 3 months) I usually ride it pretty hard So, it suddenly loss balance and I fell forward, sliding on my stomach for 5 meters. The wheel was still on, and keeps working. Only light injuries, and the wheel is intact. I rode it today (not exceeding 30kph), and seems to work like any other day. I will see to get a replacement board after all. I thought that it was ok after 4000km, but it seems not 3 13 Quote Link to comment Share on other sites More sharing options...
Popular Post Cress Posted July 5, 2022 Popular Post Share Posted July 5, 2022 Thank you @vBlitz for posting about the crash. It's a great advertisement for safety gear. We need to spread the word that no amount of testing insures the original motor-controller is safe. There isn't a guarantee that the motor-controller caused this failure but the original board is ABSOLUTELY GUARANTEED to have a short service life. Nobody needs extra opportunity to test safety gear, we're supporting that industry already. 5 1 Quote Link to comment Share on other sites More sharing options...

Screws on mosfets should tighten gently with hands. The lack of conductivity between mosfet body and radiator must be checked with tester.

It could be related to a bad unit, or some glitch in the gyroscope signal processing. I did see an instagram video of Adam riding it up a tree. It was hugely impressive, as is Adams skill. But, I did wonder if this may have upset the wheel in some way as I doubt Mr INMOTION had ever thought someone might try a spot of tree climbing with a V12…HT or otherwise!

In no case is acceptable to send the boards to your costumers like that, when you must have known from your own assembly processes that you needed to grind them short. Kevin started his rambling about his new V12 driver board that had soldered legs that needed to be trimmed to his length of preference. Unfortunately, he then went further saying that they may be too long and thus could short on the heat sink. I happened to have received my new driver board, and had a chance to examine the area of concern. On the whole board, there are only three spots that may be of concern. And they are the three phase wires that were soldered in near the center of the board. For the rest, there are just ample clearances. On my original board, the legs were trimmed very short. In contrast, on the new board, they are longer, and they looked just like Kevin's. However, the lengths are still insufficiently long to cause shorting. Also, there would be thermal pad material between the end of the legs and the heatsink. I don't see an issue. Since they are phase wires, I prefer them to be longer in order to increase electrical contact surface area. For me, I don't see supporting evidence that there is a quality issue here. As I was removing the mosfet tab screws, I paid special attention to the tightening torque on all 12 mosfets. And I have to say, those screws are very lightly tightened. I wonder how many DIYers have cracked those plastic insulators. Incidentally, I went in person to pick up my board. It was given to me in a really protective, large bubble cushion packing material package. The board looks to be similar in quality as the original, and the 12 mosfets were basically perfectly aligned. 5 Quote Link to comment Share on other sites More sharing options...

The board looks to be similar in quality as the original, and the 12 mosfets were basically perfectly aligned. I also noticed the longer legs on some of the solder points. It doesn't seem to be an actual issue. There is a fair amount or (chunk) of compound between the board and the heat sync in these areas. What i found more interesting about the video, and maybe i missed it since i watched it quickly.. He didn't show testing of the the mosfet screws to the heatsync for conductivity.. So i just find it odd to mention a quality issue and totally leave out a step in the process all together. I do generally like his videos and they are very informative. I just think the talk about the v12 is on a negative track for a long time, so people are naturally looking for anything at this point to call it out on. I personally didn't find the board swap to be all that difficult or annoying.. Yes its a lot of screws, but really that is it. One thing is for sure, i would not tighten the mosfet screws down with any electric drill or screwdriver.. I broke enough of the plastic washers just applying normal pressure by hand. 4 Quote Link to comment Share on other sites More sharing options...

Cress Posted July 8, 2022 Share Posted July 8, 2022 (edited) Communication between EUC buyers and Inmotion is not transparent - but the video from e-Rides shows Inmotion was listening to good advice from someone, somewhere and Inmotion's choice deserves "thank you." 99.999% reliability in Manufacturing is a result of active choices.. If Inmotion changed the packaging because they listened to engineering we can hope Inmotion continues that kind of thinking. And 'thank you' e-Rides for good news through the video.

Should have been like this from the beginning of the replacements. I am glad they are adjusting and doing it more quickly now. This is the type of response needed to regain trust back to the brand. As long as these boards are actually trustworthy. We will know soon enough. I see tons of new riders and people getting their v12's all over facebook. If something is amiss i think we will know pretty quickly. I really hope this turns around for the v12. I honestly love the wheel. If they can get the quality controls back to where it needs to be, i will look forward to the v13 or whatever is coming next. I catch myself looking at the master and other wheels, which all look really good and fun. But they still look like garage projects to me. Which doesn't equate as a bad thing to me. I just cant bring myself to spend that kind of money for something like that. 5 Quote Link to comment Share on other sites More sharing options...

Popular Post James M Posted July 11, 2022 Popular Post Share Posted July 11, 2022 Hi Everyone! I'm new to euc riding and love it very much. I purchased a v12hs with a replaced board from Eeves. They stated they preemptively replaced it before sending. I'd love to ask you guys if there's anything I can do to limit the possibility of a cutoff on my V12. I already intend to limit the speed to about 40kmh would greatly appreciate any advice any of you have including settings and safety advice. Thanks so much! 5 Quote Link to comment Share on other sites More sharing options...
