FlipSky 75100 Pro V2

[chuyskywalker]

Has anyone fitted one yet, I just ordered one hoping all goes well.

I've used this before on a escooter (fiido q1s, second picture, black box with blue tape around it) build and it does everything it says and well. It can be a bit to figure out what each connection is and how it should be wired up as the website docs are definitely english-as-translated, but they're a heck of a lot better than most other's I've seen in the same boat.

In re different switch/speed settings, I started off with a Flipsky 75100 three months ago and ended up upgrading to the V2 Pro after it blew a fet. Before that, I was using a Cycle Analyst / Phaserunner setup, the latter of which ended up failing. I explain all this because I still have the Cycle Analyst. Let me quote part of the user manual to help explain the relevance:



With that understanding, the analog signals being described / tapped into is both ends of the shunt resistor. The Cycle Analyst doesn't need that connection to take the input voltage from a typical three wire throttle and send whatever preconfigured throttle out voltage, which you connect to one of the ADC pins on the Flipsky. The only thing the Cycle Analyst really needs is V+ and V- from the battery, which I provide with a custom harness terminated with XT90s going to the Flipsky and 18AWG wires in parallel terminated with an XT30, which ends up terminating to a JST connector connected to the to the CA, but I digress.

The CA can be configured to take input from a digital switch and have it switch between different throttle settings/profiles that ultimately affect the throttle voltage signal on the pin connected to the ADC input on the Flipsky. Since I already had a CA kicking around and some general familiarity with how it works, this solution was easiest for me. It's also an extra $150 if you don't already have kicking around (CA-SA)

Though I might try taking a swing at coding a solution in LISP. I'm kind of annoyed this functionality isn't already baked into VESC as an ADC control type.

Hello, I understand that the flipsky throttle circuit operates on a 3.3v circuit. Can the cycle analyst by programmed to run on that voltage for the throttle? Or can the VESC also run ok the 5v signal?

Edited based on later posts:

The CA will allow you to map a 5v throttle input to output 3.3v.

 

[chuyskywalker]

The VESC is similar. It will take throttle input on the 3.3 or 5v circuit.

Eh, sorta. The vast majority of VESC ADC's will not explode if you feed it > 3.3v, but it will clamp the value at 3.3v. So if you take a regular throttle and feed the hall 5v, the typical 0.8-4.2v range will get a very large chunk of it just "missing". Just feed it from the 3v rail on the VESC, though, and most halls will work with that and adjust accordingly (or put a voltage divider on the signal line, but that's a lot more work.)

If it's going throttle -> ca -> vesc, then you'd just have the CA remap the throttle min/max to match the vesc's 3.3v max adc.

From a quick look of VESC schematic & F405 DS, feeding throttle signal powered by 5V (resulting in max 4.2) would cause the relevant STM pin to operate beyond absolute max ratings. Relevant ADC pins are not 5V tolerant & for pins that are not 5V tolerant, max allowed per spec is 4V.

3.3v or potential divider on 5V would be safe.

Hi, i have the 75100 v2 on order for a 52v power wheels project I’m building, wondered if anyone knows the voltage output on the power switch as I’m hoping to also throw a relay to activate my 52v to 24v converter for the legacy parts of the car at the same time, is it battery voltage or something else like 5v etc. I notice it’s 3-wire, is that for button illumination or volt readout I’ve seen on some handlebar switched throttle? If so could that help me?

According to Flipsky, the traces for GND and BAT+ pins can support 0.5a, so in your case about 25w. But the IGNITE pin should not care where the 52v comes from. So for accessories that need more than 0.5a, you can connect to the main input power cables, perhaps adding AWG16 wires with the AWG10 wires in the controller’s battery connector, then connect Battery+ to the input side of the key switch (if it has integrated volt meter), then the output goes to your DC/DC converter and to the IGNITE pin, and the AWG16 GND wire connects to the DC/DC (-) and the gnd wire of your switch if it has a voltmeter or display.

You don’t need a relay using this method assuming your switch + in and + out are of sufficient gauge.

This is assuming you didn’t add a Warn 5,000 lb winch on the Barbie Jeep, in which case you will definitely need a relay between the switch and the 100a DC/DC converter. Lol. Just checked the total load of all accessories and make sure the switch and wires are not overloaded.

Has anyone tried to install a gear switch? 1/2/3 for these vesc like a conventional ebike controller?

I would prefer having gears so that i wont overspeed / wheelie everytime i move off..

Ok, we know a typical ebike 3-speed switch can only send signals for low speed and high speed, and the controller knows that mid speed is default if there is no signal. Speed 2 is the same as disconnecting the switch.

The 3-speed switch has 3 terminals, 1-2-3. Position 1 connects 1-2, position 2 connects nothing, position 3 connects 2-3.

Connect the center contact to 5v+
Connect contact 1 to a voltage divider that turns 5v into 2.5v, connect that output to ADC15
Connect contact 3 directly to ADC15.

So now we have:
speed 1, 2.5v,
speed 2, 0v,
Speed 3: 5v.

From here it will require some code that I don’t know how to do but basically:
If ADC15 is 2v-3v, max amps and rpm set for low torque and speed.
If ADC15 is 0v-1v, max amps and rpm set for mid torque and speed
If ADC15 is >4v, max amps and rpm set for maximum performance.

On that controller there’s only 3 ADC channels and one ADC1 is throttle, ADC2 typically regen throttle, that leaves only ADC15.

Spintend has an ADC accessory that lets you plug in a ton of peripherals

Please Ebs1971,
Could you provide me with more details regarding your 52v 1500w motor.
Best Regards
ps: Hope my question is not too off topic.

Hi, sorry for the delay. This is what I’m using right now as a home made mobility scooter that I can also have some fun on The hub motor is from AliExpress and rated 48v 1500w and cost about £160.00 The battery is from Amazon 52v 19.2Ah and about £375 with LG 30700 4800mAh cells. The Flipsky 75100 pro v2 controller works well with this setup. I’m still learning about the settings on a daily basis for over a year now since I started with the 75100 that overheated constantly.

Hello everyone, i just placed an order on the "new" 75100 Pro V2 (apparently now the controller supports on/off switch and does not require an external anti spark switch thingy.)

Just wondering, has anyone already bought theirs and tested?
How is the performance, any overheating?
Any changes internally other than the on/off switch?

I mistakenly ordered the older version that has the traditional aluminum case around the PCB. I regret modifying the phase wires of I'd trade it in for that more modern looking V2.
I downloaded the free windows version of VESC tool. I need to research a bit more to successfully connect it to a bench test hub motor. I'm having issues with the settings and controls it has.
Wish me luck as well setting it up.

Thank you very much for your kind answer.
You mentionned £, so I guess you probably know
Brushless motors from UK
I am surprised not to see discusion regarding motors from this company, there is probably a good reason for that.
But of course as I am a bit rookie with ES I probably miss to discover the appropriate threads.
Cheers

Just feed it from the 3v rail on the VESC, though, and most halls will work with that and adjust accordingly (or put a voltage divider on the signal line, but that's a lot more work.)

I used voltage dividers in the past but yeah I do this now, the hall throttles I've tried so far work just fine when running off the 3.3v rail.

I've seen them mentioned a number of times, but there are a lot of companies that make (or sell OEM) motors like that and they are not that popular for Ebikes because they require more work to adapt. I do think there is some potential for high power outrunner brushless motors though.
