Hello grace/flipsky

As you know I've just purchased the vesc 6.6 for a stand up scooter project so I will give updates to my progress with the board, but after our conversion unfortunately the motors you stock is too high a KV for my use on this occasion, and I can not get a hub in the 6.5 inch size so I will have to keep looking for a motor that suits my needs around 100kv or less and 3kw range.

Ideally what the ebike community need is a board with all the same specs that has double the output 24s and 120amp battery that would then tickle the tastebuds of many diy ebikers including myself to power our bigger hubs, If you could then link a small waterproofed screen to the board to display and modify the settings and the PC can be done away with they will sell like hotcakes.

I will give feedback on the vesc when it arrives, for me it suits my small projects perfectly 12s 3kw max is ideal and with the new dual vesc you have the small motor controller market on lock down keep at it decent value good job.

I don't think I need to say about the benifits of vesc motor control but for those that ain't heard about it check out vedder.se.

Prices?

That looks great for skateboards. Too bad it can't handle just a little more voltage. All of my bike packs are 14s.

I would have thought you can get away with 13s as long as you don't field weaken the motor beyond its 60v vs rpm/kv and then apply regen so the volts shoot through the roof but not played with one yet to say for sure or do I plan on going above 12s or near the regen vs kv limit.

Nice to see another Vesc 6 Controller.
By now the latest version was only available from Trampa, but thy were asking a crazy high price for this little thing of hardware (Trampa Vesc 6 costs about 300USD).
This one is available for about half the price, the amp rating seems to be similar and it looks well built.
Maybe the powerstage of the Trampa controller is a bit better with it's direct FET's (low inductance board with ceramic caps installed very close to the FET''s), while Flipsky is using differnt FET's, BUT twice as much!

The latest trampa model the 75/300 specs are impressive but it's a £1000 that's crazy price, And is the 240amp continuous battery's or phase ? If it's battery close on 20kw should be enough to cook most motors in seconds if it's phase it could be as little as a third so 80amps battery at 72v is still near 6kw constant and that looks more practical for a device of its size but makes the price even more shocking.
What are they building that for I thought they build mountain boards ?
I'm crazy but I wouldn't jump on a 20kw mountain board or even if its 6kw on a dual setup making 12kw would be :shock: to ride and on price

I wonder what market it's aimed at, the specs seem a little crazy to me it's got to use lipo to be on a board or there will be a giant 18650 stack alongside a minI esc just how many crazy people want a death board ?

Hi, Ian, glad to see you here. Yes, I'm sorry that disappoint you for your motor. We tried,but in reality , cannot do it just 1pc. we're here to get more professional suggestions from end users . Thank you for your sincere suggestion here. IF more peopole want the ESC with 24S/120A, we'll consider to design it ,but not base on VESC, 'casue VESC only support 13S max, but our new product base on vesc6 can reach 120A/150A, still support 12S as max . Thank you for all information!

No problem with the motor I understand, I may have an alternative lined up so no worries.

I see trampa board's has a vesc with 75v limit ?
Ever seen the film, field of dreams ?
Theres a saying in it "If you build it they will come" that's only true as long as it's reasonably priced with decent spec.
I'd test and buy such a product, by the way list your basic price's before admin throw a hissy fit.

Another nice feature would be to have a 1-4v analog throttle input. While skateboards would use a PWM RC receiver input, an ebike or scooter generally uses an analog hall effect throttle.

AFAIK it does have such input, but maybe Flipsky can confirm it.

I can confirm vesc 6 uses all types of throttle interface no modding required but older vesc and esc can use a hall throttle with a servo tester, Its as much about the software side of things as hardware with fully mappable throttle inputs and tons of features that I've not got a clue to say the full capability of, but I do believe with the built in terminal window a bit of code can be entered so an additional button flips the throttle into a regen lever, I need to have a dig about and a play when it arrives.

Ive got an old gs4 phone and the vesc project bluetooth app did not like android 5.0.1 so I had to install a custom firmware (lineage os 14.1) to get the app to run on the plus side I've got 7.1.2 installed now so I'll use that as a control and display, Its a nice clear bright 5inch oled can't fault it for the price they can be picked up for peanuts.

Motivated! actually , we have plan to design ESC with high voltage and big current, but still not decide some details. Pls wait, I will release it some day.

The vesc actually has two adc inputs. A third is also available but unused unless you want to code your own application for it. A button can also be configured on top of the two adc's.

The existing firmware allows for:
  • forward
  • forward reverse center
  • forward with button reverse
  • forward reverse on adc2 and button brake
  • forward brake center no reverse (tesla mode)
  • forward no reverse brake button
  • forward no reverse brake on adc2

Ok so it can do regen (brake) and go into revers.
Do you now if it can be configured so that it works like modern ebike controllers?
I mean one hall-throttle for throttle, and a second one for use as a variable e-brake.

Cheers district9prawn.
From what I gather on the current firmware to use the throttle as a regen lever ADC 1 is used for a hall throttle and then ADC 2 shorts RX to ground via a button to swap the throttle function to regen.

I Like this feature alot it will keep the handle bars bare but with loads of function, I like to use hydraulic brakes this way all I need is an extra button and a hall throttle along with 2 step ignition that turns the ride on the stage 2 activates lights, A good mobile phone holder to hold the dedicated galaxy s4 so I can use GPS map, video camera, while viewing the vesc's data and that's my Santa list full.

Just got to work out how to do video overlay with it like ackermaniac does.

Yes, this is possible. I do this on my ebike. The VESC-Tool software allows you to customize the voltage mapping for both throttle and brake so in theory a very wide range of analog signals could be used.

I did also try the configuration where you have a variable throttle which can be turned into variable brake when you hold the brake button. I didn't like this mode because pressing/releasing the button while the throttle is fully on makes the controller instantly switch between full brake / full acceleration. This caused a lot of stress to the belt drive system I was using at the time.

I took another look at the source code and you can actually use two adcs and two buttons. The buttons short rx and tx. I wonder if this could be a handy way to trigger field weakening. I've been looking for a crude way to implement it that is within my rather poor programming ability.

Other than the sudden inversion of power with button brake, I feel that it is also asking for accidental WOT woes. I don't think my uncoordinated brain could handle it.

I've read that rx to gnd flips the throttle to a brake and then tx to ground activates cruise control.

I never use cruise control so if that could be coded to a field weaken/turbo button all I need to do is bunny hop and knight industries ain't got shit on me, KITT who? I got more tech in a kiddies scooter.

Can not argue with that postage I ordered on Sunday and received it on Friday.
First impressions are the quality in hand feels good and the packaging it arrived in was as electro static with plenty of protection so i received with a perfectly non flawed finish to the device.
