Why does VESC offer more power on the same hardware?

we can only speculate why FM limits power - could be cost, could be fear of not meeting regulations (trying to fit into the 750W PEV limit), could be because it’s designed for the worst case dumb user and to avoid lawsuits, could be a combination of the above… but why VESC has more is simple:

  1. brushless motors always can deliver more power than they’re rated for as long as you keep an eye on temperatures
  2. low end torque is limited by the controller, not by the battery - so a stronger controller can easily produce more low speed torque with the “same hardware”
  3. it’s a DIY community so many people are happy to accept smaller safety margins than they maybe should (even though FM seems to have questionably small margins as well recently, see 120V mosfets on 113V board on the GTS)
  4. lastly any speed increase from a VESC controller is mainly because we can change whether/when/how pushback occurs while the true top speed of the motor is still dictated by the battery (this is why XRV’s don’t let you break speed records set long ago by XR riders)

we actually dont have to speculate. it is obvious.

check it: Future Motion is a worldwide company that is authorized to retail potentially dangerous products, build and store them without oversight, ship them in the mail, in airplanes, and overseas. speaking of overseas, thats where all their pcb manufacturing and lithium battery cells are sourced and imported from(china). companies need to be insured in order to operate. whether the insurance that covers employees or a physical space where explosive batteries packs are assembled and stored, to individual five or six figure component shipments.

also regulatory bodies that govern company status: IRS, FCC, FAA, USPS, DOT, CPSC, equivalent Californian agencies, possible international trade oversight agencies require you to be insured in order to license you. no insurance, no sales, no product no company.

insurance companies, on the other hand, are governed by actuarial math and underwriters that: do not want to take risks and don’t have to. this in practice gives the insurance company damn near unlimited and infinite ability to force a company to do just about anything they demand as a liability concession. you cant really fault onewheel CEbrO guy. his hands are tied. hes living his dream, making these things, employing people, doing as much as hes allowed to. but the company its infrastructure turned out to ya know, not exactly how he imagined when it began, as each regulatory hurdle clears, the independent, “this is my business, ill do it how i want” atmosphere, the start up culture that once was, erodes. compromises are made. and any one of us would do the same.

and one day, vow, and indyspeed, and fungineers are going to draw the attention of the to whoevers job it is to enforce H.R. 973, or Reese’s Law, or someone will sue them after thekr kid dies (and these companies will be absolutley gutted by high powered personal injury lawyers during litigation. when they are compared to the gold standard in limiting liability for PEV manufacturers –Future Motion–in court, they will have no grounds to claim they did anything whatsoever to try and keep their consumers safe and alive.

given enough time and scale, sometime between building a board in your garage and selling it to a stranger and becoming and international vehicle for savage house firesand and snapped collarbones, any similar company will have to pay, make similar decisiona, or find a new gig to make their nut.

Future Motion and Kyle Doerksen get a lot of flak but its important to realize: there was no option to do it differently. the limiting of the power of boards, etc, were not descisions made. they were demands acquiesced.

source: 10 years of doing Drug Harm Reduction Outreach at the largest music festivals across the country discovering the complex interplay of competing agencies, regulators, and the underwriters of mandatory insurance agencies and how descions that put people at risk are not made by event organizers, and not negotiable. because liability.

liability is the cornerstone of the legislative and justice systems, and is the reason you cant have a medium rare burger at a chain restaurant, why you cant provide safe spaces for people having difficult psychedelic experiences at events, cant have end-user modifiable pevs. hell its why the stigma around drug use, addiction, treatment & recovery looks like it does..

This would have been a valid point until 18 months ago - but since GTS/GTS-XL they decided to massively increase the power output with the same old motor and with a battery that on paper is weaker than the GT battery…
