A delicate board, the only thing that keeps you from crashing, doesn't even get a cardboard box?! They came inside a larger cardboard box. For any distributor playing along at home the Sherman mudguard box is a good shipping box for these being sent individually. Quote Link to comment Share on other sites More sharing options...
EUC Phenomenon Posted May 30, 2022 Share Posted May 30, 2022 (edited) It might be wise for everyone get in contact with their reseller and ask them if it's possible to put it in to a box. I've worked in a large parcel facility, over the Christmas period. It's a real eye opener how rough the parcels are handled. The parcels a tipped onto a conveyor belt and so there are parcels dropping onto other parcels. Amazingly though, most parcels are undamaged. But something like the controller board in a sealed air bag without a box, is asking for trouble.

The Brahan Seer Posted May 30, 2022 Share Posted May 30, 2022 Could it be the replacement of the MOSFET's has pushed the issue further down the line of the circuit board? So some other component or solder is now being over stressed? Watching the replacement board install although doable is asking an awful lot from customers to be able do it themselves without any issues. In the 1970's oil crisis it had such an impact on the availability of oil it affected the quality of fibreglass in yacht building. People today stay clear of boats built from 1973-onwards for a few years due to poor build quality. I think we may have a similar situation now with electronics due to the worlds disruptions etc etc. So unfortunately maybe now is not a good year for any EUC. 3 Quote Link to comment Share on other sites More sharing options...
Wolverine Posted May 30, 2022 Share Posted May 30, 2022 And I thought the situation couldn't get any worse. It turned out that it's possible. I really hoped that things would be resolved and that we could leave it behind and move forward. The manufacturer should buy all these V12 models back from the buyers so that we can forget this fiasco. Honestly, this is disappointing. 1 Quote Link to comment Share on other sites More sharing options...

For the good of the cause I hope everyone, including Distributors installing the new board keep a record of MOSFET temperature because if the Hunteck component can't be cooled enough the new board will have an unpredictable service life. The pictures, particularly the board posted by @evans036 , above, are concerning. Electric Unicycles put 'beta testing' in a unique perspective. Part of our post board swap testing is a 1km ride, checking the temps aren't spiking more than expected and the overall temps of the components that warm up are doing so at an expected and consistent rate. I am sure not every distributor will have enough time for this, so we will see more failures. 5 Quote Link to comment Share on other sites More sharing options...

If there is a heat issue we should see it first when the wheel is ridden up-hill (operating with a load and without fast air-flow to cool the heat sink). I hope Inmotion did test the Hunteck MOSFET pre-production but we'll know in a few days. /Richard Quote Link to comment Share on other sites More sharing options...

I also doubt other distributors will do such a test ride before shipping out the unit - based on information released by Inmotion so far, we are all supposed to assume the new board fixed everything...? Sure the spin test isn't perfect but it likely saved a bunch of people from eating pavement on defective batch 2 units. Perhaps its not a bad idea to repeat this with the new boards. We as riders need to be more proactive in protecting ourselves instead of putting anymore faith in this company.

Perfect for my needs, and as I believed, of a better quality and reliability than GW ... and then this sh*t happens with the wrong mos fets, or whatever it really was or is - still. And then everyone is happy anyway because there is a quick solution, but no no, that's not how it should be. It turns out that the new boards may be just as flawed as the ones they were supposed to replace - it's a farce. And now I have reached the point where the idea of a V12 has been put on the shelv - then I might as well buy an RS19 with a blackboard - and then just remember to charge it out in the open - if it should catch fire.

rolis Posted May 30, 2022 Share Posted May 30, 2022 Hey everybody! I have recieved my v12 today. Started it up and it stopped working in about 2 minutes. Internals still on, but no balancing, no input/output on the top panel, "please repair" screaming at me. It was just a glorified speaker with some LEDs. I tore the wheel apart, checked all connections, checked all mosfets and caps for values and nothing was wrong hardware wise. Then I turned it on and it worked until I connected via inmotion app for ios. Okay so long story short. When you get your new wheel, DO NOT USE AN IOS DEVICE. If you do, you will need to disconnect the batteries to reset the board and try again with an android phone. If you want some details on how I checked the wheel, go to our telegram channel:https://t.me/+KS5mOWU-yvQ4MzY8 2 Quote Link to comment Share on other sites More sharing options...

Paul g Posted May 30, 2022 Share Posted May 30, 2022 (edited) 19 hours ago, Brendan "nog3" Halliday said: I expressed to Inmotion that precisely this problem would happen in shipment if they didn't supply them already attached to heatsinks like every other driver board they supply. Vindication is not a good feeling here, sorry that you're having to deal with this. Ok, to be clear I want to know so I can identify if it happens to any of the 50 boards I'm replacing. Please, spill the beans. The guys tested the MOSFETs after the incident and were burned. The board failed on the same day it was mounted on. I’m so furious on InMotion. I can’t say too much. I’m waiting just as you to see what will other experience with the new boards, but definitely is not a good sign. InMotion has access to the logs from when the fail took place, they should provide us with more info. The more boards are tested the more info we gather. They do not have good engineering team for the boards. That becomes more and more clear to me. The “We trusted a lot the 100V MOSFETs and that’s why we used them in the 100.8V wheel” is not an argument that would come from an (well seasoned) engineer.

Silverfish Posted May 30, 2022 Share Posted May 30, 2022 So, how long realistically until there is a clearer picture of what is going on here? If these failures on the new boards are not just somehow outliers, what possible solution is there going to be after this? Is there any other realistic outcome than basically cutting my losses, tossing the thing in the garbage and moving on? (possibly riding it til it bricks first). I really like riding my v12, but if this doesn't work out I might just be done with EUCs. Quote Link to comment Share on other sites More sharing options...
Paul A Posted May 30, 2022 Share Posted May 30, 2022 Yes, paying thousands and then having to fix problems seems a bit unfair. KS18xl has never had a problem in all these years. The new wheels are surprisingly problematic. Quote Link to comment Share on other sites More sharing options...
