I don't think it really changes the nature of my question though. When you are designing a circuit and selecting a capacitor, you don't select a capacitor whose voltage rating matches the "nominal" voltage it will be exposed to – you select one whose voltage rating is (typically something like 1.5x higher than) the maximum voltage it will be exposed to. At 9:53 in the teardown, we see 160V rated DC bus capacitors. I still find that 108V controller rating a bit odd, although it probably doesn't really mean much in this case.

If you search the web for V13 images, you'll see that there are 4 screw holes located on the actual battery shell about level with the bottom of the flappy mudguard. If you also watch Bonheursurseine's french review he actually shows you a shot of them. 2 Quote Link to comment Share on other sites More sharing options...
soulson Posted January 15, 2023 Share Posted January 15, 2023 After further review, I see now that there are two fans in there. They're part of the headlight module and appear to be 40mm units. Looks like they pull air through heatsinks attached to the headlight and push toward the heatsink attached to the inverter. I wonder if they run at full blast whenever the headlight is on, even if the wheel isn't moving. 40mm fans tend to be pretty loud, and those look like 3-wire fan harnesses without PWM speed control. Glad to see that there are two, though. Quote Link to comment Share on other sites More sharing options...

Thanks for the information! The fans also look like they're positioned to cool the inverter heatsink in addition to the headlight. Do they also turn on when the board temp gets high, even if the headlight is off? Like when riding up a steep hill on a warm day? Quote Link to comment Share on other sites More sharing options...

Like when riding up a steep hill on a warm day? I have yet to hear the fans turn on when the headlight is off. The open bottom heatsink seems to be pretty adequate in cooling without any fans. I haven't ridden in really warm conditions enough, so I wouldn't know if the controller needs a fan or not.. I believe Marty made an overheat hill test, so I guess we can see if he noticed anything.. Will watch that in a few minutes. 🙂 Quote Link to comment Share on other sites More sharing options...

He said that he has never noticed them turn on unless the headlight is on. It would be funny if people do manage to start overheating the thing and the "fix" is just to ride with the headlight on for more airflow Edited January 15, 2023 by soulson 4 Quote Link to comment Share on other sites More sharing options...

Hellkitten Posted January 15, 2023 Share Posted January 15, 2023 The V11 has the option in the app to turn on the fan regardless of if you’re riding or not. I’m sure inmotion would have that feature on the V13 as well. 2 Quote Link to comment Share on other sites More sharing options...
techyiam Posted January 15, 2023 Share Posted January 15, 2023 (edited) Don't understand the FUD being spread regarding overheating of the V13. Raising overheating concerns out of thin air, from non-owners. Thankfully, Marty extended Overheat Stress Test has put this to rest.

soulson Posted January 15, 2023 Share Posted January 15, 2023 Sorry, my intention is not to spread FUD. I'm an engineer, and I just like to understand how things work. The headlight quip was a joke. 1 Quote Link to comment Share on other sites More sharing options...

Josiah Posted January 16, 2023 Share Posted January 16, 2023 (edited) One of these blips is our wheels. Not sure which one though. Go Jonny Go! If it left the port at Shenzhen about ten days ago then it’s about halfway. So it should be just north of Honolulu now. I posted this before but it makes me so happy looking at it.

It's the Michelin Street Pilot 2 in 80/90-16.. there's not many street tire options to swap out a 22x3" tire.. so the 80/90-16 is smaller than the stock knobby.. as a result, I get a little more torque, but lost top speed. The speedometer is now 15% incorrect.. at 55mph on the wheel, gps speeds show 48mph. As far as performance, besides the aforementioned torque, the street tire is a lot more smooth and quieter. 3 2 Quote Link to comment Share on other sites More sharing options...
