Another nice feature of the OW BMS is the ability to actively balance as long as the charger is plugged in. A Daly completely cuts off as soon as the first cell reaches 4.25V. This way you will get a better overall balance, even with bad battery packs. So don't forget to unplug it after a couple of hours. ;-) Learned that in one of Marios Videos.
@@MrDmadness I don't think I'll be creating such schematics myself. This is something the community is working on though, check the Discord channels like discord.gg/BEMe3Gyt. There's also work underway on a VESC Onewheel Wiki page
Can you measure the thickness of the lid? I'm trying to DIY one of these and don't necessarily want to wait for flowglider to restock. He already uploaded the template for the lid, I just need to know how thick.
if you don't mod the BMS you cannot use the latching switch, you need to tell the BMS to turn the board on/off, hence the purple wire - there's diagrams on pev.dev and the spinningmagnets article
Will there ever be an Android version of Float Control or is there something equivalent? That's the one thing holding me back from changing my board to VESC. I'd love to jump in and help contribute to the firmware!
The Rx/Tx pins are 9 and 11 - but you do have to program it. You can use your vesc to do it. Benjamin Vedder himself shows you how to do it right here: ruclips.net/video/PFFiVxFHDM4/видео.html
Don't quote me but I think that the leads are just backwards. In DC red is typically the positive pole while black is negative, this differs from 120vac at the house where black usually carries the load and white is the neutral ( remember on a/c wires black is pirates .pirate = danger white flags are neutral ) so in essence the leads SHOULD be on a dc circuit red positive but red is negative on one wheel..
The switched polarity would be inside the battery box. But I haven’t had to open it up yet - at the controller end I use the makerspev connector with the XT60 coming out of it, it’s wired the normal way
@@surfdado so the leads on the battery are normal ( red hot )? And the polarity gets switched in the box ?? Are they using a protection circuit to make sure the pcb does not cascade error ? Or is the polarity switching a component of the re Gen? I'm curious what the purpose is
I will come back here when my XR will shows signs of wear.. VESC seems like the future for European onewheel rider. I will avoid this company (FM) as much as possible because of geographical distance..
Well, I think little focer v3, even being the best focer out there for a balancing vehicle, is VERY pricey, and is a shame that has problems with bluetooth and the pulldown resistors configuration is that bad. For such expensive device it should work PERFECT. I am very disappointed, I was about to get it, but not anymore. Both things should be correct since the very beginning, I wouldn't expect less.
Converting to VESC doesn't necessarily save you money and is not plug and play - very true. All VESCs today are still general purpose controllers, not Onewheel controllers. To me the most important factor is that a VESC is powerful and reliable. The rest is up to the builder.
Step by step… i watched part 1 and part 2 jumps to the whole thing being assembled, i thought it was going to go into actually step by step unless i jumped a video.
yeah, you're right - making decent RUclips videos is super hard and I just don't have time/resources to do it properly. Also, I'm not very good at DIY/hardware stuff so I decided against making the video where I put it all together, sorry
I hope you're aware you're ensuring the future of our one wheeled hobby. Thank you so much.
Haha, so much pressure
Excellent stuff. Your wire management looks clean, very nicely done sir.
Thanks - I think the camera angle was hiding the messy bits ;)
Amazing work! Thank you for sharing your progress. I hope to buy these components and build a FunWheel one day.
Very wise to use the metal plate as the controller module protection but also as heat exchanger.

I had no idea, good to know! Looks like I didn't pay enough attention when I watched Mario's video haha
Those thermal pads make a world of difference with the v3 focer.
Wish i had friends like you! Dam. I build- homes, motors, cars, not electronics!
Can you explain the whole bms thing, like pros and cons of keeping the bms?
This is not an easy subject to address. I should probably dedicate one entire video to this topic at some point...
@@surfdado this would be great for people who are converting with just a VESC to start.
Any wiring schematics ? Excellent work .
Wiring for what? The Bluetooth module? There’s a RUclips video on how to do it, look for VESC Bluetooth
@@surfdado an over all schematic. I'm familiar with that bt pcb I've used it on many arduino projects

I’ve measured 1.45mm thickness
He restocked
@@joejones6579 Thanks for the heads up.
Is there a wiring diagram for the momentary switch? So will this work with the latching switch that comes with it on a stock xr.
if you don't mod the BMS you cannot use the latching switch, you need to tell the BMS to turn the board on/off, hence the purple wire - there's diagrams on pev.dev and the spinningmagnets article
Will there be a video on how you've wired everything together?
I'll try to show that in my next video
@@surfdado Amazing, thanks for all the work you've done for the community!
Studying and about to order everything and make a xr pint hub growler ?!

The VESC Tool has an android app - but I’m not aware of anything like FloatControl or YoursTruly on Android
Great video as always! What thickness of the thermal pad or does that matter?
I chose the 1mm but I’m not really sure how other thicknesses would do in comparison- or if it matters much at all
What software do you need for the Bluetooth module
if you search for VESC NRF there's a youtube video from Benjamin Vedder explaining the process
@@surfdado awesome, thanks
Surfdado, how did you determine the NRF51822 bluetooth modules rx/tx pins? Did you have to load firmware?
The Rx/Tx pins are 9 and 11 - but you do have to program it. You can use your vesc to do it. Benjamin Vedder himself shows you how to do it right here: ruclips.net/video/PFFiVxFHDM4/видео.html
Do you not have the screws in to hold the controller in place?
Not with this flowglider enclosure
Any idea on what type or amp hour the 18650 cells are in the XR battery? And how many it holds.
What size and thickness thermal pad did you use?
Did you have to switch the power polarity? I've heard that it is backwards on the XR.
Don't quote me but I think that the leads are just backwards. In DC red is typically the positive pole while black is negative, this differs from 120vac at the house where black usually carries the load and white is the neutral ( remember on a/c wires black is pirates .pirate = danger white flags are neutral ) so in essence the leads SHOULD be on a dc circuit red positive but red is negative on one wheel..
@@MrDmadness That is what I thought. It was FMd. Best to check it before connecting to the VESC.
@@RafaelSaucedo Shouldn't matter if he's using the existing onewheel battery harness I suppose.

Would the momentary switch work on a stock/standard XR?
it probably would work, but you will void your warranty 😜
the soldering blobs on the main power leads look lil shady
lol, that was my first reaction too - idk what he was thinking there. I was tempted to go fix it myself 😂
I will come back here when my XR will shows signs of wear.. VESC seems like the future for European onewheel rider.
