Endless Sphere

A few remarks/suggestions from the screenshots provided: -Cell High protect is ok at 4.2V, but cell high recover is a bit low, meaning if after charge the battery stabilizes at a voltage higher than this then the BMS will remain shut off, not allowing you to ride. I suggest you put is a bit closer t...

Built this over the winter with my 8 year old. He took every nut and bolt off the ski and did the fiberglass! So please give him a like and sub on youtube. :) Very cool build mate and kudos to the kid :thumb: Can't wait to see more videos with the new settings Couple things I could use some help wi...

Hi mate, I found this product page on the chinese version of alibaba, there are pictures that should help you determine all the wiring : https://item.taobao.com/item.htm?spm=a230r.1.14.1.79531b15lWqOxV&id=666636865981&ns=1&abbucket=1#detail Let me know if you can't access the link from w...

... please make sure that this is ok before everything else, if a motor burns it's far less drama than a battery ... Before starting to burn, there should be a remarkable rise of the battery temperature, no? I have 2 temperature sensors in the battery, which came with the BMS, and they didnt show A...

That's so cool, you guys are lucky.
If it wasn't so cold there and if you guys had better food I'd really consider going there

Hmm... I dont know what an expensive BMS costs, More than ten times this price.... :wink: Orion BMS for example. The maximum continuous current is limited to 100 A (because of the controller), and the maximum short term current is limited to 270 A (because of the battery). The BMS can support more ...

Good job on swapping your BMS, plus it seems to be an interesting one I haven't heard of before, which does active balancing, a relatively rare feature on cheap BMS :thumb: But don't forget what I told you before: you need to make sure your cells can deliver that kind of current safely. This means y...

You did see that the forks are held onto the steer tube with glue and pieces of plastic, yes? No, I did not. On the picture"2280D56B-4230-419D-8393-9A592AD1B3AD.jpeg" you can see what looks like welds between the steering colum, the transversal part and the bike forks. But I agree the pic...

Looks really cool, this minimalistic style. :thumb: What I am asking myself: Can you drive on the streets over there without a license plate ??? Nope. But problem is I cannot even get a license plate in the first place because there is no way to homologate a vehicle for the little guy, you have to ...

As I keep procrastinating on making the carbon fiber parts ( partly because it's very tedious, but also because I'm missing some stuff that can't get since the lockdown), I'm working on some details/accessory parts. Especially improving water protection. The bike is not intended to be ridden on the ...

haha, just ignore the haters man, it's a cool build so it would be a shame not to see more of it.

Thanks for the very nice comment mate, made my day too! :D Main reason I say it looks insanely dangerous is because of the gigantic amount of power this powertrain could deliver.... :shock: Right now you're still gently cruising at low power, but if you were to tune both APT controllers to their max...

Hi guys, 8) It's been a while, but I've been in lockdown for the past two months already. Still am today while writing this, and still no idea when it's gonna end, if ever. Anyway... At least it's been a great opportunity to find more time to work on the bike, and the good news is that it's done, ba...

We demand to see more pictures of the beast!!!

That looks insanely dangerous, but well done on the build!
I can't imagine how it would be possible for anyone to control that thing at full speed with such powerful motors and controllers though.

How much are they? how big? the main reason i was looking at the mobipus 72600 was because the programming looked easer and had the dash build it. it also was small enough to fit in the airbox of a crf450. i had heard of the password system but i thought you just got on password to use it, but now ...

Btw i'm converting the 75-5 of my 2013 ZERO XU to Hall sensor with that RMB29 pcb that i already have. This is for my XU converted to FX

Y'a moyen de suivre ca quelque part? ca a l'air cool ! si tu as un lien vers un thread ce serait top!

Does anyone know if a zero 75-7 will work with the mobipus 72600? No Idea for your specific question, sorry, but all I know is that you should avoid Mobipus, unless you got the passwords somehow (in which case please be nice and share it to the world XD). But, good news maybe, I know for sure the N...

Hey Dui, what vehicle did that LiFePO4 battery come from? Did you ever find out? I'm not so sure, there is a sticker on it saying "VTRUX". My brief search on google got me there, apparently Jay Leno tried one: https://www.youtube.com/watch?v=p5STy6HRZEQ Seem like it is some kind of hybrid...

Progress has been slowed a little bit, I broke my printer so I had to repair it first. Now everything's fixed and I can print again. :bigthumb: I've been experimenting with the wrinkle paint and finally got some decent results. For that, I had to try printing with new materials. So far I was almost ...

Nice report, thanks

Those are some tiny ridiculous phase wires for a 6kw motor.... My 2kw motor phase wires are at least five times beefier.
Weird.

But as long as it works then it probably doesn't matter!

The red cover of the ANT BMS-did you print that yourself? Yeah I designed the enclosure then printed it on my printers I am asking, because the ANT BMS you recommended in my build thread was "naked" (and that is what I need, because it must fit into the battery case). Yep unfortunately th...

Not a lot of progress these days, but at least some I really wanted to use wrinkle paint on the BMS box, but unfortunately all my attempts failed... The reason is that this paint needs to be baked, but plastic desn't really like the head and it just deforms and warps too much. Too bad because I quit...

Is there some kind of way to convert this motor to hall sensors without having to open it?
Like adding some kind of circuitry that could convert the sin cos position into hall sensor outputs?

Awesome work bro, Glad you got it street legal, well done!
