14:00 Probably that the phase cables wired to the controller have huge impact on the heat transfer/ dissipation. Large wires = better heat transfer. Flat wires = better heat dissipations due to surface to cross section ratio. I bet that the heat transfer on the bottom of the pcb phases is less important than that.

Electrolytic construction isn't much different from NMC cell construction. NMC can be a jelly role for cylindrical cells or many thin sets of cells stacked together to get a pouch or rectangular cell. Caps in cans are just a jelly role, but they could be made with many thin layers as well so the cap is a rectangle. Ceramic caps are many thin sections of ceramic with aluminum deposited on the ceramic and many layers of that all stacked on top of each other to make a capacitor. Foil sheets and an insulator between them is done already. Thin film caps are made that way in rectangular shells.

I'm surprised that the industry seems to be moving towards voltages higher than 100v (nominal) due to the dangers that come with it. Obviously any voltage can be dangerous but 100 becomes deadly quick. I was planning to do an electric motorcycle build and go with the 96v route but I would need something like 1200 phase amps to get the power I want. Torque is the whole benefit of electric in my opinion anyways. I guess it's only a matter of time before PEV motor manufacturers start to make super low KV motors to take advantage of the high voltage controllers coming to the market.
@de-bodgery10 күн бұрын
Motors that operate at 131v/32S are already plentiful. 400v motors are pretty common too. There's plenty of options of motors designed with low enough KV's and tested for 400v applications. Never mind all the used motor market from electric or hybrid cars.
@eelcohoogendoorn804410 күн бұрын
I agree that low voltages are nice; but you dont really have much leeway in Kv/Kt actually; in practice there is a pretty hard floor due to the realities of practical motor construction. Im working right now on a design wound with a split pair of 2x3 phases, with two independent controllers on the same motor; effectively putting the controllers in series and getting double the effective voltage to tame your R and L. This is pretty common in electric aircraft for redundancy, but it also makes for very peppy light EVs while staying under the 75V legal limit for low voltage devices.

Regulations aside, im also happier with the lower voltage myself, as far as batteries I have to plug and unplug, let along actual work on something. Since phase currents are independent from all this; the only place the extra current might bother you is in the bus.

@de-bodgery10 күн бұрын
Yes it's possible, but unlikely, VESC is very resilient against bricking as a general statement. It has 2 storage locations in flash for firmware. It loads from one and then installs new firmware in the other. If something goes wrong, the CPU can still boot from the other storage location. This is never 100% sure, but it does add a layer of redundancy that most other firmware operations in other controllers lack! If the new firmware loads and boots successfully, only then does the backup older copy get over written with the new firmware. Having said that, you still have USB, UART and SWDIO for reflashing and recovery if they are bricked. Id try USB first...see if the PC based app can connect to them and then use VESCtool to update the firmware according to the video that Flipsky has on their channel. I've used that exact procedure many times on their controllers without issues. IF you need the firmware to use with an STlink and SWDIO, contact Flipsky to get that.

Stick with VESC first of all! STR500, Seven, Tronic are all repairable.
I am all for new VESC variants...especially with higher voltage...but I am still cautious since the 3Shul crap that burned up on me.... and some amateur-isch design choices can be seen here as well... Hope this will improve in the final design of the PCBs
Really... "Amateur-ish design choices"? Care to be specific instead of making an unqualified statement?
The inside of a KO controller looks like a kid’s science fair project
Is it that good?
no
looking to change the controllers in my scooter, i have the laotie ti30 with 2800 watt 11'' hub motors the old controllers are 45amp each square wave i believe. What setup would you recommend? two of these g300 would be expensive! tried flipsky low end 75100 but had very poor results.
Spintend is a little better than Flipsky.
dont like the tall connectors for phases. i see you need to get above component height, but why not move them to the other side of the board?
TOLT mosfets are 2.5MM thick. Even the added copper on the bottom of the SEVEN 30 which lays flat on the board has to be thinner than that. About all you can really do is lay some copper across the phase busses on the bottom of the board due to thickness constraints of the mosfet package.
What about XTAR VC4SL, is it better than Liitokala lii 600?
So you think your going to be getting one of Torp’s new tp50 motors?
Maybe, but it will a while if someone doesn't donate or lend one to me.
Any idea of the price points for the controllers? I don't think you mentioned it, could have missed it. Thanks!
I hope it works with 15 pole pairs motor ?!
Why wouldn't it? It's VESC after all.
Which one is better between two if them? Can the xtar dragon vp4+ or lii-600 discharge battery and show the real mAh?
Keep watching my videos. I answer this question.
In general, a spintend can be a higher quality product than a flipsky.
Yup...agreed...said that several times in this video.
Whats the mosfet package? I'm trying to look it up but cant find it
Watch the video...all in there!
14:00 Probably that the phase cables wired to the controller have huge impact on the heat transfer/ dissipation. Large wires = better heat transfer. Flat wires = better heat dissipations due to surface to cross section ratio. I bet that the heat transfer on the bottom of the pcb phases is less important than that.
Trampa STR500 uses those studs like you describe. They solder them in place too. Pretty sure they will never sheer off! The BAC8000 I have for repair, the phase solder pad is completely eroded away. Nothing to solder onto like you describe! I have to entirely depot the controller, remove it from the shell and then use a brass screw via the underside and some added copper foil on the top side to even get a decent current path back.
Yeaaahh nice to see my favourite electronics geek friends on every new controller video haha
9:35 I imagine that one day, just like prismatic cells, square electrolytic capacitors will exist and reach better fill factor on the pcb amd enable to even be closer to the fets for improved performance by reducing inductance and resistance...
Electrolytic construction isn't much different from NMC cell construction. NMC can be a jelly role for cylindrical cells or many thin sets of cells stacked together to get a pouch or rectangular cell. Caps in cans are just a jelly role, but they could be made with many thin layers as well so the cap is a rectangle. Ceramic caps are many thin sections of ceramic with aluminum deposited on the ceramic and many layers of that all stacked on top of each other to make a capacitor. Foil sheets and an insulator between them is done already. Thin film caps are made that way in rectangular shells.
@@de-bodgery Yes that's what i'm saying. I work in battery industry. Anode, separator and cathode.. in a roll or a stack.. but for the form factor, the joules of storage capacity per apparent surface on teh pcb would be better if square than round... this woudl allow to stack more joules or to stack then closer to the fets
@@Doctorbasss Yes...well can style electrolytics are abundant and cheap. Probably why you see them so much. I do agree that close as possible to the mosfets is best. I've been following your YT channel for years. Sometimes I watch your content more than others. I don't think I knew you worked on batteries for a living...just as a hobby.
@@de-bodgery I dont share my consultingwork on the internet. Only personnal projects. I indirectly worked on projects for Lucid, Tesla, Rivian, ZERO, Rimac, BRP and many others. Last time I was employe I was developping ultra quick laser welding machine for large EV battery production.
@@Doctorbasss Very cool! So laser welding...was that for the 4680? PRetty sure, what you've done...your battery experience is in high demand.
just a comment to add some algor1thm food. kind of a starter, who's adding a main course?
Thank you .
Thanks maaaate!!
Looks very exciting! Would love to upgrade a dualtron to something like that.
👍
😊
Hey man I'm an avid viewer of your content, love what you're doing. I'm a motor manufacturer based out of India, would love to connect and share a chat. 👍🏻
Hi...ping me on Facebook : Richard Gumfaw
I'm surprised that the industry seems to be moving towards voltages higher than 100v (nominal) due to the dangers that come with it. Obviously any voltage can be dangerous but 100 becomes deadly quick. I was planning to do an electric motorcycle build and go with the 96v route but I would need something like 1200 phase amps to get the power I want. Torque is the whole benefit of electric in my opinion anyways. I guess it's only a matter of time before PEV motor manufacturers start to make super low KV motors to take advantage of the high voltage controllers coming to the market.
Motors that operate at 131v/32S are already plentiful. 400v motors are pretty common too. There's plenty of options of motors designed with low enough KV's and tested for 400v applications. Never mind all the used motor market from electric or hybrid cars.
I agree that low voltages are nice; but you dont really have much leeway in Kv/Kt actually; in practice there is a pretty hard floor due to the realities of practical motor construction. Im working right now on a design wound with a split pair of 2x3 phases, with two independent controllers on the same motor; effectively putting the controllers in series and getting double the effective voltage to tame your R and L. This is pretty common in electric aircraft for redundancy, but it also makes for very peppy light EVs while staying under the 75V legal limit for low voltage devices.
@@eelcohoogendoorn8044 Low voltage means high current. Is rather have higher voltage. I run a 6 phase motor on dual controllers myself. They aren't in series. This is effectively 2 motors wound on the same stator in parallel. Where are you located that you can't exceed 75v? This isn't the case in the USA. I can build at whatever voltage I want here.
@@de-bodgery you can exceed 75v anywhere; but in the EU its no longer a low voltage device and different regulations apply. Regulations aside, im also happier with the lower voltage myself, as far as batteries I have to plug and unplug, let along actual work on something. Since phase currents are independent from all this; the only place the extra current might bother you is in the bus. It depends on the application I suppose but adding an extra mm2 of bus wire usually isnt the issue
@@de-bodgery The two motors wound on the same stator sounds like exactly the thing im talking about btw. Im calling that 'in series' since you have effectively half the L and R to push against per controller while the same phase current limits apply.
I have 2 of these I can't get to work. Is it possible I bricked them with the vesc tool by allow them to try a firmware update? It's been months since I picked these up but when I did I was just clicking buttons. I have the tools to reprogram the processor but I don't know where to find the image.
Yes it's possible, but unlikely, VESC is very resilient against bricking as a general statement. It has 2 storage locations in flash for firmware. It loads from one and then installs new firmware in the other. If something goes wrong, the CPU can still boot from the other storage location. This is never 100% sure, but it does add a layer of redundancy that most other firmware operations in other controllers lack! If the new firmware loads and boots successfully, only then does the backup older copy get over written with the new firmware. Having said that, you still have USB, UART and SWDIO for reflashing and recovery if they are bricked. Id try USB first...see if the PC based app can connect to them and then use VESCtool to update the firmware according to the video that Flipsky has on their channel. I've used that exact procedure many times on their controllers without issues. IF you need the firmware to use with an STlink and SWDIO, contact Flipsky to get that.
Well the primary symptom I’ve identified is no USB. I’ve powered it with a lab supply and I get a blue light but nothing enumerates when I plug in USB. I’ve tried multiple boards, multiple cables and multiple computers. I hooked everything up and applied a signal through the servo input just to see if it would respond but the unit isn’t even drawing enough current to boot the processor.
@@lusher00 Ping me on facebook. USB applies 5v to the controller and then the 3.3v supply ought to power up to and that's what powers the CPU. At least LED's ought to light up! Seems you have something else going on possibly and not bricked CPU's from a bad flash.
@@de-bodgery I’m not sure how to ping you on Facebook. I’ll have to investigate. I don’t believe Vbus is connected on the supplied USB cables. They are only 3 wire so I would assume D+/- & ground. I have LED’s on when I supply power but I don’t know what a solid blue LED means.

Thank you for this! All options are good options! I'd try this out for my crf450 most defiantly!! 718
long time no see!
Yeah...a little over a month since my Spintend video...definitely slowed down video content with everything stolen! Lots of things I can't do anymore with no cameras, no electronics equipment, no EV parts, no machines to the tune of about $70,000!!! Watt Wheels claims "I ruined his business", when thanks to all my equipment he stole, if anything, I made his capabilities 10X better!!! In between time, I've got nothing but my laptop!!!
@@de-bodgery yeah that stunk. the universe always finds balance
@@lezbriddon So i must have been a royal shit in a past life if the "universe finds balance"! In this life, the "universe" for the second time has laid a world of hurt on me!
@@de-bodgery haha no I don't subscribe to the previous life thing I reckon the universe will get him in this one somehow
Scammer
To whom or what are you referring? I can tell you I'm no scammer. I firmly believe that if its wrong for it to happen to me, it's wrong for me to do it to others! I'm far from perfect at being non-hypocritical, but Its what I try to do with everything! As a result, I'm a strong supporter of Ukraine. I know I wouldn't want to be invaded, destroyed, robbed and killed...so it's equally WRONG to happen to them! If trying to be honest and truthful and true to my word and consistent in how I treat others vs myself makes me a scammer...if that's your implication...then so be it. I have to say, that's got to be the most bizarre definition of a "scammer" I've ever seen! You might want to look up what that word means.
@@de-bodgery I’m not sure why you would bring a political argument to this at all, particularly because the reality of your example is much more complicated than a 2d version you have laid out. Anyhow, I like your channel and find your efforts both useful and informative in other regards. Take care!
The only 2 options they have (as of the time of this writing) are the ECP4"lite" and something they're hyping up as "The One", which they claim is a combination of the "might of the Electro & Company EC4P V3 Motor with the strength and Braun of the EC5P Motor". I wonder how the quality of those stacks up and if it doesn't, how can they keep getting away with this? Other than ignorance, of course.
Yeah customer ignorance, hype marketing and total disregard for their customers! That's how.
Their website has stopped working for a long time, which is strange.
works for me
@@de-bodgery In Russia they cut off
@@vova4585 Yeah...get a VPN...plenty of those for free or cheap so you can circumvent your tyrannical government and hide your internet traffic.
I would like to measure the capacities and internal resistances of approximately 220 18650 lion batteries by first charging and then discharging them. Is there a charger you can recommend? I would appreciate it if you could answer me.
VP4+ will definitely do all of that for you
@@de-bodgery Thank you for your attention.
Your video was very informative, thank you. I am stuck between XTAR Dragon VP4 Plus and XTAR DRAGON VP4L Plus charger, which one should I buy?
I've never tried the 4L or taken one apart...I don't have an opinion on it.
How many amps does this controller produce at 75V? 200? I couldn’t find the information anywhere, and the official website doesn’t work.
"Spintend 85-250" and discussing it in the video pretty much says it all.
Hello richard gumfaw , cloud you help me pliz , i have aproblem with my memo design evo 9
Is it possible to put a lighter spring in it?
probably, but I don't know if such a spring exists.
@@de-bodgery do you think that if i cut one circle of the spring, it will be lighter to twist?
@@niklaspalmlof2005 You have to wind up the spring a full turn to get the tension it has from the factory. I think if you don't wind it all, you'll have that softer pull you want.
I'm new to this programming and stuff so much need to learn, i can only do micro soldering and that's it nothing more
micro soldering is a skill in itself and way more than most people can do.
can backup firmware em150
IF I had the controller...
One of the studs broke off my KO controller. I see what you're saying toward the end. Anyway to reattach?
Did you see my repair video for a KO Pro controller? It's not different for the FSPEC or Rush controllers, but I can do that for you. Hit me up on FB.
i think you can cut a small thermal pad to sandwich between the top plate and board part rubbing?
I used kapton tape
You forgot to mention that the software for PC is crap.
I liked my C4-12 but two of the springs have recently failed, like I told they would do!
HEELO, WE ARE ANT BMS FACTORY, SHALL WE GET CONNECTIONS?
Hi Jimmy...I believe I've already reached out to you on Facebook....aka Richard Gumfaw. If not, ping me please.
How many number of turns did you put?
Watch the videos...all in them
I have been doing solar/wind/EV's for over 40 years. I never had to load an app to get anything of mine to work or see what it is doing. Presently I am building a LiFePO4 battery with a JBD BMS which came with absolutely no instructions on how to install or use. I am having to scour YT videos and blogs to try to figure it out. What a sad state alternative energy has progressed to.
I think you've missed the point of smart BMS! This isn't sad, it's excellent! Your dumb BMS can't tell you anything about pack status or be programmed for differing charge and discharge and balancing profiles...all things you can do with a smart BMS! Your dumb BMS can't tell you state of charge or if your pack is performing badly. You have no logging capability either, but you do with a JBD smart BMS! For these reasons, I'll never use a dumb BMS again!
@@de-bodgery I have missed no points. I don't believe you even read my posting. Complicated technology, no instructions, no independence security. This is my first battery bank where I had to install any kind of BMS, dumb or smart. I always used a voltmeter, load tester and performed an equalization charge when I could. Simple. The worst of all is if we in the US ever get into a conflict with China, my system could be shut down.
@@ForbiddTV I read your entire comment more than once. You are entitled to your opinion about smart hardware being "inferior" due to its robust feature set, but I can also say that everything you need to do externally, a smart BMS does itself. As someone that has been using smart BMS's since 2015, I'd never go back! If you are looking for someone to fight with, I'm not going to argue with you. What I will say however is that smart BMS's are far superior to dumb ones or no BMS every day of the year! Do yourself a favor and learn how to use a smart BMS. It's not rocket science and frankly once you do, you won't be going back to whatever you use now.
@@de-bodgery I'm trying to learn how to set it up, they sold me this piece of junk with 28 wires sticking out of it with not one wiring diagram or word of instructions, even in Chinese. "Everything you need to do externally, a smart BMS does itself". Not if it can't even be hooked up. None of my other previous batteries ever needed a BMS, in fact no such thing even existed. We are going backwards in technology.
@@ForbiddTV Did you contact the seller for wiring instructions? Did you google for them? Wiring a BMS to a pack is pretty easy. I rarely look at the wiring diagram since the silk screening on the BMS itself tells you what each wire does. Probably best bet for you is to go back to horse pulled wagons and oil lamps since this is all "too advanced" for you!
Wasn't RDS on resistance lower on low side mosfets?
I think you mean N-channel mosfets. They are used for both low side and high side current switching. The same can be done with P-channel mosfets, but they are used much less commonly. Rds is very dependent on the mosfet. You can have high or low Rds in any kind of mosfet.....N-channel or P-channel.
Can this be used for surron ultra bee?
yes
Haven't seen anyone complaining about bright buttons and blue LCD backlight ruining night vision and distance vision during scotopic/ectopic conditions. Should be orange or red-amber like in a BMW and airplanes.
That's because they are RGB LEDS. Set them to what you want. LCD backlight changes with ambient light.
