So they are there, I just hadn’t heard of them. Did either of those two result in a crash? Btw, how many mainboards have you or the manufacturer replaced under warranty last year?

Adv.Andrei Posted February 19, 2022 Share Posted February 19, 2022 Hi Gents, Bought a inmotion v11 In dec2020 but couldn t ride it due to health conditions. Want to start riding it and i was browsing through the internet avout the power pads and ended up at the bearings issue. Now, i live in uk where the weather is what it is. what s the best strategy to make the most out of it. I ve seen some 3d printed parts for the bearings. Thought might ask for a extension of the warranty, the wheel has less than a mile on the odometer, a few times around the living room. any advices? kind regards, Andrei 2 1 Quote Link to comment Share on other sites More sharing options...

It's all upside. I'd definitely add the seals, they do seem to help. And I would look carefully at the 'grease' that's in the bearings. I am probably misremembering which wheel shipped with an unfortunate choice of bearing 'grease', but while you're adding the seals it wouldn't hurt to check. BTW, glad your situation has improved to where you can start riding the thing! Edited February 19, 2022 by Tawpie 1 Quote Link to comment Share on other sites More sharing options...

(Even when you use those 3d printed parts.. Adding thick layer of grease "All around" will help. And when you add that grease, I MEAN IT.. add plenty. So that groove disappears in grease.

Although, it’s best to use grease as thin as reasonably possible under the bearing cover, since there is some friction going on. 1 Quote Link to comment Share on other sites More sharing options...

I'm a euc newbie No. I never had any pads. You can very well ride it without them and in the beginning even recommended. They help with braking and riding uphill. You can install them later when you know what you need. They help with more aggressive style which is not what you should go for as a newbie. 2 2 Quote Link to comment Share on other sites More sharing options...

I'm a euc newbie For a newbie, I recommend getting good at your wheel before getting power pads. You'll be able to try out different foot placement and body movement without restriction (test out what you like). I rode 300 miles before I got power pad (Clark Pads). I like them because they help give you better grip and stability. Good for jumping and high speed riding. Try getting "fly pads" first. They are foot peg that are helpful for added leverage. I used the thingiverse file to print my own (PLA or PETG, 90%-100% infill) and they worked great.

Popular Post Wolverine Posted February 23, 2022 Popular Post Share Posted February 23, 2022 Hi @YelJuw and welcome to the forum! You're right, most of the V11 owners uses power pads on their euc, and there are good reasons for this. First let´s talk about what is used. The most popular ones are Inmotion's own power pads and Clark Pads. Clark Pads offers special models for Inmotion V11 alongside with universal power pads and power pads made for the other euc´s. So why do people prefer to use power pads on V11? In case of V11, the difference between using a power pads and not using it is like difference between night and day. What causes it? It's actually quite simple, using a power pads gives you much better control over the V11 unicycle, improves stability, improves handling, and the one stays on the unicycle even when the situation gets hairy. By hairy situations I mean unexpected potholes, wobbles, emergency braking etc. As a separate bonus, you get better acceleration and better braking force. As braking becomes more effective and the braking distance decreases, great benefit has already gained in this area alone by using power pads. Of course, the more aggressively you ride, jump, go to forest, etc. the greater is the need for power pads. I recommend learning to ride a unicycle beforehand, and if that skill is achieved, it's a good idea to install pads, especially in case of V11. When you install power pads, please use Velcro to easily adjust when you feel so, and to place them as you wish. 3 1 Quote Link to comment Share on other sites More sharing options...

val4o Posted March 5, 2022 Share Posted March 5, 2022 What is the voltage that the v11 should reach at 100% battery? Also is there a problem if you leave it charging more than 3 hours after it reaches 100%? 1 Quote Link to comment Share on other sites More sharing options...
Tawpie Posted March 5, 2022 Share Posted March 5, 2022 Roughly 84V. Keep in mind that the wheel's internal voltmeter has its own inaccuracies, so 83.8 or higher is just fine. And absolutely, you should leave it charging for an hour or two after the light on the charger goes green. This balances the individual cells in the battery pack and extends its life. Don't pay too much attention to the % meter, it's typically optimistic. The voltage is what matters... 1 1 Quote Link to comment Share on other sites More sharing options...

Green light is not charging anyway, it's charged and charger not charging. (Unless the V11 is radically different than gotway/kingsong.)

Tawpie Posted March 8, 2022 Share Posted March 8, 2022 29 minutes ago, xorbe said: Doesn't this happen whether it's plugged into a charger or not. "sort of". As I understand the tribal lore, the BMS will bleed charge off of cells that are above 4.2V and continue to charge cells that aren't yet all the way to 4.2V. But in order for the slower-to-charge cells to 'catch up' you have to have the charger connected. Hence the advice to leave the wheel connected to the charger for an hour or two after the green light. Incidentally, the green light is optimistic and tends to go on 'early' anyway. Shorter time to green (or 100% indicated) is better, right? 3 Quote Link to comment Share on other sites More sharing options...
Richardo Posted March 8, 2022 Share Posted March 8, 2022 Does the green light have anything to do with the transition from constant current to constant voltage? Quote Link to comment Share on other sites More sharing options...
Popular Post RagingGrandpa Posted March 8, 2022 Popular Post Share Posted March 8, 2022 (edited) 16 minutes ago, Richardo said: Does the green light have anything to do with the transition from constant current to constant voltage? No. The CC->CV transition ("peak power point") happens much earlier than the green light. The green light on the charger activates always during the CV stage, when current has fallen below a threshold like 300mA, as shown below (green shaded region). All "standard" chargers provided with new EUC's today continue CV after the light is green (as shown below). Some EUC's (e.g.: Sherman) have internal circuits that disable the charging input after saturation and balancing are complete (a behavior implemented in the EUC, not the charger). And many aftermarket chargers (e.g.: all eWheels/JiaRui selectable fast chargers) are different, and do stop the CV output based on their own threshold.

Richardo Posted March 21, 2022 Share Posted March 21, 2022 @Paradox I won't be immediately helpful here, those partially threaded screws are sort of custom and I don't know how to identify it. I did ask my retailer if it's possible to order replacements or if they knew how to describe it in a search, though. 1 1 Quote Link to comment Share on other sites More sharing options...
Tawpie Posted March 21, 2022 Share Posted March 21, 2022 (edited) They're called "shoulder screws" or "shoulder bolts" and come in standard sizes. You'll need to measure the length and diameter of the shoulder, the length of the thread (or overall length) and the thread diameter and pitch. Eyeballing it, it looks like an M3 thread.
