Could you please alert the user Waulnut tho, he didn't complete the test correctly, his wheel could still fail. Quote Link to comment Share on other sites More sharing options...

Battery was at 100% when tested and miles was 500, we don't know what batch/firmware though. Im charging my wheel to 100% now and will test it later Edited January 5, 2022 by spitfire1337 Quote Link to comment Share on other sites More sharing options...

Note that lead solder is less brittle than lead-free, and can make a more reliable connection. Also, tawpie had a bunch of good info Also note that you need remove any old solder before using a quality lead solder like cardas quad. Its well known that mixing types of solder can lead to less than idea connection durability. 3 1 Quote Link to comment Share on other sites More sharing options...

Popular Post spitfire1337 Posted January 5, 2022 Popular Post Share Posted January 5, 2022 Well damnit man, I was charging up to be able to do the test. Wheel was functional prior. After a while I went to check on it and the screen was off and wouldn't respond. Took it off the charger to try and power it up with no luck. Wheel has resistance trying to spin so sounds like blown mosfets. Adding it to the tracker. @rolis if you want to add it to yours here's the info: Firmware 1.5.0 Batch 2 Battery somewhere between 70%-100% as it died while on the charger. Miles ~120miles 5 Quote Link to comment Share on other sites More sharing options...
ESB Posted January 5, 2022 Share Posted January 5, 2022 Are any of these attempts correct? I've been doing this for the last 30-40 mins and finally feel like I sort of got the hang of it but I'm tired now, lol. https://1drv.ms/v/s!AuTwFMSJBw0gmbJnvrDJR8erXBDvVw Something that definitely helped was to increase the speed limit. I originally had it set to a low 20mph since I was still learning and the wheel only has a few miles on it. So the tests were hard because it would start tilting back / alarming way too early. Raising the speed limit + alarms gave me more control while doing the tests. 2 Quote Link to comment Share on other sites More sharing options...

Raising the speed limit + alarms gave me more control while doing the tests. Not ideal executions as the wheel spins out at max speed and prepares to shut off. Ideally, you increase the tilt angle progressively to keep the speed in control, like 60kph constant and now you yank it the other way. It'll apply the stress without shutting off, and you can repeat this as many times as you want.

ESB Posted January 5, 2022 Share Posted January 5, 2022 (edited) ok thanks. I'll give it another go later. Thing is heavy and my arms are tired now. It's such a joke that we/customers are being asked to do this on a $2000 product. Feels like a basic test case that shouldv'e been done at the factory /rant Edited January 5, 2022 by ESB 2 Quote Link to comment Share on other sites More sharing options...
supercurio Posted January 5, 2022 Share Posted January 5, 2022 @ESB couldn't agree more. There's no doubt a % of customers will not be able to run this test perfectly enough, as well as enough successive times to trigger the fault. Then crash and get hurt. 2 Quote Link to comment Share on other sites More sharing options...

Right 😝 On a side note, I've seen somewhere someone suggested their wheel drained the batteries after the controller died. I'd suggest if your wheel failed the test to disassemble and disconnect the batteries so that one problem doesn't end up turning into another down the road. Who knows how long it's going to take us to get replacement boards. 3 Quote Link to comment Share on other sites More sharing options...

EUC Phenomenon Posted January 6, 2022 Share Posted January 6, 2022 Will it be okay to test my wheel with zero miles on it, I got the wheel yesterday. Should I also do the test in the opposite direction? This is my first wheel. 2 Quote Link to comment Share on other sites More sharing options...

I don't know that the direction change will make any difference—other than the test operator may be better/worse doing the 'fast tilt in the opposite direction' going one way or the other. I'd do it both ways. Can't hurt, when riding you'll be accelerating then braking and going from braking to acceleration so in real life you'll stress it in both directions. Welcome to the insanity BTW, once you're over this hurdle and tackle the learning part, I think you'll enjoy yourself immensely. It requires a certain stubbornness to learn, and wearing quality gear to help keep you uninjured, but in my opinion, it's worth all that and then some! (the usual caution about saving for wheel #2, and wheel #3-... applies) 6 Quote Link to comment Share on other sites More sharing options...

So true. I'd do this outside on the grass by the way. The wheel is heavy as lead and if you drop it it'll 1) leave a skid mark, 2) might break the MOSFETs because the wheel stopped too suddenly or 3) run through your house and put a hole in the wall after it knocks over a couple tables and chairs. If you're on grass you don't care about the skid mark, the grass will be easier on the MOSFETs because the wheel won't quite instantly stop (that has been known to fry 'good' parts), the grass will not make as many marks on its beautiful shell, and you won't wreck your living room.

Popular Post spitfire1337 Posted January 6, 2022 Popular Post Share Posted January 6, 2022 (edited) I've been in the process of tearing down my V12. Interestingly looks like a bit changed from B1. There's now a separate LED driver board on top of the controller. The one with the aluminum brackets is from wrongways teardown of a production model, and the one with the controller is from mine. Editing to note that wheel now free spins with the phase wires disconnected. Edited January 6, 2022 by spitfire1337 4 Quote Link to comment Share on other sites More sharing options...
