120V dual VESC for E-scooter

I’m willing to finance a 120-135V controller, that i need for my e-scooter prototype. I’d like to have a dual controller (like Stormcore 100D), but 120V version and somewhere up to 150 Amps

Nice one, Vadicus and all compliments for building it. I like all the features that you built in but i'd rather have a dual controller, due the limited space in the scooters body, besides every "gram" matters. We're building a hyper scooter here, with a goal to be the fastest on the planet, so please guys, help me out here and let's write our names in the history of hyper scooting :)

A step up scooter? Unlikely to make a history here. It's not hard to make them go 100km/h with 80-100v.  It's been done many times. Don't even need a high voltage controller or dual drive.

I reached 124km/h with a Chinese 96V controller, but it's to heavy and big and i lost a lot of space and had to make a smaller battery - thus shorter range. Goal is to reach above 150 km/h, therefore i'm looking for improvements. I'm really desperate to get some help.

Yep, and there is a reason for that, would you think? Here is some reality check. Building a high power controller is not a matter of swapping a few parts and call it a day. High voltage and currents require larger clearances, larger caps, more expensive parts, more complex power systems, isolation, etc. If you are serious about building it, I mean not a prototype that kind of works but a a reliable reproducible product, brace yourself for months if not years of designing, testing, failing, redesigning, blowing up things, flushing thousands of  down the toilet, thinking you are almost there, blowing up again, redoing, testing, rinse and repeat a few times. You'd better have tons of patience and a sizable budget. And all of that to go above 100kmh on a step up scooter with a smaller controller?

I got the point but i'm still gonna go for it.

An odd beginner question: - Regarding the more expensive parts, caps, etc - if i get all that, does the VESC software still stays the same, or it needs an upgraded code etc. as well ?
