Mindspkr Posted March 28, 2022 Share Posted March 28, 2022 Is there a max temperature for the V12 that I should be monitoring and looking out for before stopping and letting it cool down? How hot can I let it get. I’m going for a ride up to Mount Baldy on Glendora Mountain Rd., California. We’re taking 2 V12s. Quote Link to comment Share on other sites More sharing options...

Please do not do this because V12 is not safe at this moment and even manufacturer has said that we should avoid riding with those things. They also said that if we are eager to ride, then the speed must be low. Eventually the cut out will happen with the current V12s, the only question is when it will happen. 1 5 Quote Link to comment Share on other sites More sharing options...
Popular Post rolis Posted March 30, 2022 Popular Post Share Posted March 30, 2022 Hey everybody. I asked my dealer about the v12 HS boards and the HT: ”… The V12 HS will be available for deliveries in the middle of May. InMotion just informed us that they have delayed the production of motherboards and the motherboards will be ready at the end of April, instead of the end of March as they initially promised. InMotion told us that they will probably be ready with the production of the HT by the end of April. …” 4 1 5 Quote Link to comment Share on other sites More sharing options...

Are the pedals sky high? I doubt they are taller than the V11 pedals and those are still OK after one gets a bit used to them. Quote Link to comment Share on other sites More sharing options...
StudentOfTheWheel Posted April 1, 2022 Share Posted April 1, 2022 i rode my wheel in some moderate rain 2 days ago for about 30 minutes total, think i could have some water damage but not sure the next day, i had a cutout (i think) during my ride. rode for about 5 minutes, stopped at a stop light, and when i started riding again the wheel just turned off. i dont think there was a beep or anything, and the wheel turned back on afterwards and i kept riding it with no issues. since it worked fine afterwards im thinking i might've just over-torqued it? but the wheel was at nearly 100% and i've never over-torqued it once in 300+ miles later on in that same ride the wheel said "please repair" so i pulled over and ran diagnose on the inmotion app but it said there were no problems? so im just confused. seems weird that these two things coincidentally happened the day after i rode it in the rain for the first time. i didn't use the kickstand after riding in the rain by the way, since i've seen people recommend against that what do you guys think? regardless im happy my sherman max is arriving next week so i can let the v12 sit until the new mosfets are ready, and i can probably just have them check for water damage while they replace the board Quote Link to comment Share on other sites More sharing options...

It's tough to say... the V12 is supposed to be pretty water resistant but when you add water to a known issue it's a total guessing game. Your plan to ask them to check for water problems when the board is replaced is the one I'd go with if I were in your situation. 1 Quote Link to comment Share on other sites More sharing options...

Tesla cars batteries are also sealed, but they have a valve that lets gases vent out of the battery pack, that is because the LiIon batteries are releasing gases during their lifetime and you need to provide an escape route for those gases. It is also important in the case when one, or more, of the battery cells fails and it starts burning. That’s when the battery pack needs a venting valve. All EUC producers must provide one in every pack they build as a safety feature (and I know at this point the notorious No guy will comment, saying that if the new EUCs will have this feature then they will cost too much, so he’s not happy with it. I want to reassure him that Begode will still build wheels, so he should not worry as he will be catered in the future as well 😂). 1 Quote Link to comment Share on other sites More sharing options...

Would be hilarious If they post a video of how inmotion V12 handles a failure and also a thermals runaway battery fire failure... You know, to show battery containment performance. Probably won't happen though, would be too much of a confidence flex and a not-so-subtle diss at all the competition. Sigh. Quote Link to comment Share on other sites More sharing options...
Paul g Posted April 1, 2022 Share Posted April 1, 2022 Does anyone knows if any V11 had a battery fire until now? The packs seems to be similar to V12 in the way they’re built. Quote Link to comment Share on other sites More sharing options...

The packs seems to be similar to V12 in the way they’re built. No known V11 or V12 battery fires. There was for V10 at the beginning due to inconsistent sealing with shrink-wrap + silicon, around which they retrofit a plastic battery box which protected it from water which could come from the top. Then it looks like none of their wheel caught fire (on their own) 3 Quote Link to comment Share on other sites More sharing options...

All li-ion cells are completely sealed and never vent any gases during their lifetime unless there has been an catastrophic fault. Then either the venting disk cracks open (for round cells) or the pouch cell splits open to release the excess pressure. Once this happens the cell is ruined as now the liquid inside the cell, the “electrolyte” will evaporate and the cell cannot function. This simple “venting” doesn’t generate more than a puff of gas though and can't generate a lot of pressure in a sealed pack. But as you mentioned, a cell on fire (in “thermal runaway”) can release a LOT of gas and that means the pack must have a way to release that internal pressure. I’ve read that up to 2 liters of gas can be created for every Ah of capacity for a cell in thermal runaway. That can mean 8-10 liters of gas per cell in a fire! The pack enclosure must release this pressure, hopefully in a controlled direction that can’t endanger the rider, or otherwise the pack can burst quite violently.

Paul g Posted April 2, 2022 Share Posted April 2, 2022 (edited) Ups, you’re right, thanks for your prompt observation. I mixed up my knowledge about other types of battery with the one about Li-Ion. The Li-Ion battery cells are completely sealed indeed, unlike other types of battery. With all that being said you need a way out for the gases and that’s when the valves come in handy. Sandy Munro teardown of Tesla battery pack is down bellow if you want to see how Tesla make their valves: https://www.youtube.com/watch?v=TYFyiiEwOFI Edit: In one of the S20 teardown I remember I saw that at the top of the battery pack there is a hole where the wires pass through so that hole must have been blocked with flying debris or something??? I also noticed an other safety feature in Tesla battery pack: each cell is connected to the collector by a thin wire which acts as a fuse which burns out in case of a faulty cell, making the pack more resilient.

Paul g Posted April 4, 2022 Share Posted April 4, 2022 Update: King Song thought about adding a ( as in “one”) fuse for each battery pack. Please stop thinking about Tesla standards, you are not allowed 🚫 https://www.youtube.com/watch?v=XgythTYgqr4 3 1 Quote Link to comment Share on other sites More sharing options...

Popular Post jimjam.nyc Posted April 12, 2022 Popular Post Share Posted April 12, 2022 I am not 100% sure i would call this Chooch fail an unexpected cutout. He was pretty much riding at the limits of 37mph offroad. Sorry he took a spill at that speed. its pretty insane, but not sure i would blame the wheel for this one. I guess good news is, the MOS didnt blow up, and neither did the entire wheel. Thankfully he isn't too chewed up from the fall. 5 1 Quote Link to comment Share on other sites More sharing options...

Looks like a clear case of rider error - did not maintain wheel balance while airborne, which is common cause of wipe outs on jumps. Best case you get a massive free spin tire burnout upon landing, worst case you hit free spin cut out and wheel dies before landing leading to much harder crash. Remainder of video seemed like a very long cryfest starting with the ouchie, then leading into sales pitch on gear and then more complaining about his % commission on the S20 being lower. 2 3 Quote Link to comment Share on other sites More sharing options...

Silverfish Posted April 15, 2022 Share Posted April 15, 2022 I just had my first big bail on my v12. Completely my fault, and I ran it out. Meanwhile the wheel bounced on its side a few times and spun until it turned off. But then it started playing alert noise after alert noise. It seemed like there were a couple of dozen of them one after another. All different. Mostly siren type noises, and one "please repair" in there. It went on for a comically long time. Worked just fine after. Is that just what a v12 does on a hard fall? Quote Link to comment Share on other sites More sharing options...

Better than silence and magic smoke! 2 Quote Link to comment Share on other sites More sharing options...
