15S support (and more amps)

I know this might be a ludicrous request or might have been discussed some where already (looked and searched around but couldn't find anything. apologies if so be).
But a vast majority of battery types being sold are 5S, and insane projects having even something between 8S-12S batteries.

I'm mostly curious if VESC will ever support up to 80V and perhaps up to 200-300A continiously? (So you could series a few batteries).
It might sound like a lot, but if you add weight to your project and using the ESC for anything but a quad/smaller planes, volts and amps are getting high pretty fast.

Again, sorry if this is either off topic or a silly request.
I'm amazed by this projects already flexible support and features

There are several high voltage / current VESCs around at the moment. 

Benjamin has been working on his 75/300 (75V 300A) which is still not released. https://www.trampaboards.com/the-most-powerful-vesc-yet-a-vesc-with-300a...

I am working on a second version of my popular A200S (75V 200A). https://vesc-project.com/node/339

There is also a 150kW VESC that Paltatech made for high voltage applications. https://vesc-project.com/node/144

As well as other lower power version such as the MINI4 https://vesc-project.com/node/246

Dual versions - SDRV https://vesc-project.com/node/349

That's amazing! I had no idea these threads existed or that people made their own high-powered versions of the design (I'm a bit new to this forum and community).
I'm not entirely sure I'll be able to do the soldering myself or find the time to learn or do it, so my best bet would be to wait for Benjamin or someone to sell their versions?

If nothing else, I'm extremely interested in using the VESC instead of the bulkier Mobipus controllers which seams hard to get where I live anyway.
My only other solution is to use Alien Power stuff, which has some programming alternatives, but not as feature rich as the VESC (at least to my knowledge).

Steer so clear from Alien Power System ESCs. Just don't even consider it. You'd be better off burning your cash in a bonfire, but the ESC soon will anyway.

Yeah Alien Power stuff is just generic china escs I don't think any of them are reliable.

Seeing my limited time to learn enough electro-engineering and what makes a ESC a ESC, Alien Power is the only searchable solution to my problem, which is controlling a 200A, 20S (peak 82V) motor.
I hear all you concerns tho and you confirm my suspicions, but unless I get a PCB file that I can order and a parts list for that PCB, I won't be able to solve this nut myself :)

The A200S is extremely tempting, and the closest thing that I feel that I can work with (mainly because lack of experience).

Aside from the inadvisability of buying a motor you can't control there are more than VESC based solutions.

https://www.mgm-controllers.com/ are very highly rated, I've used the TMM 25063-3 and it survived a 450A short before clamping it.

Of course they're far from cheap, but that's standard for these kinda power levels.

The TMM 25063-3 looks like a suitable solution! I appreciate the tip! Price isn't that big of an issue, so ~€600 for one ain't that bad.
Since you've used one, I have a question regarding it tho (and I'm aware this is a bit OT here), does it support FOC? I couldn't see any listing of it on the ESC.
Noise isn't really my biggest concern right now, controlling a high powered engine is hehe.

Just noticed, those controllers are rated for 15S, the motor is rated at 100V DC. I'm assuming the motor will still spin, just not at full power/potential.

Voltage ratings for motors isn't really a thing, there's just a point when the power (volts x amps) you're pushing though the windings generates too much heat and damages the motor. You get more heating from current than voltage so usually you try to increase the maximum voltage, and decrease the current for a given power rating.

You'll have to talk to MGM about FOC, we've used them with sensors though and I would highly recommend them. They also do industrial motor drives with the same/similar hardware.

Again, big thank you TheFallen for the info. I've been dreaming of building my project for about a year or two now and commercially available parts are starting to pop up that makes hobbyists like me able to build crazy stuff :)

I'll send MGM a message and see what they say, in the mean time I'd might put this project on hold until one of the more powerful VESC's models becomes accessible via payment of sorts.
Leaning towards a 4kW longboard in the mean time, the VESC v6 seams to hold up for the task.

(This is a amazing and friendly community btw, newcomers like me feel pretty welcomed!)
