Flipsky Dual FSESC6.6 Open Source Project fit with ESC6 Software Electronic Speed Controller with CAN Switch for E-Bike ESK8

I originally bought this ESC here on Amazon, but received what was obviously a returned item since the PPM wires were clipped off and the other wires and switch was missing. After that, I got a faulty unit. The third one I got secondhand, unused. It's been working fine for about 300 miles, on a 12sp setup. Battery current is set to 40 amps, -35 amps regen. Motor current is set to 55 amps.Built in switch works well, no issues yet. Heatsink works well also. I'm a 195lb rider, and after 3 successive trips up an unreasonably steep hill, the MOSFET temps only ever reached 69C. That was full throttle in a very small space in the enclosure.It's a good ESC. Not as good as something more premium like a Stormcore or Maker-X GO FOC, but this thing works, and is very small.I like buying on Amazon, since their return policy is amazing if you're buying it Fulfilled by Amazon. I'd recommend testing it immediately, so you have time to exchange it if it is indeed faulty. I built a small 12s2p battery from Samsung 25R cells just to test ESCs and motors when I get them. Only cost about $100 total and it's helpful.

As I was plugging in everything the ESC locked up and would not turn off until I manually unplugged the power. After turning it back on it would not respond and Locked up. I've ordered a new ESC but this is troubling because I didn't even get my board off the workbench before it had issues...I used the Flipsky 4.4 prior to this so far that hasn't had any issues. Fingers crossed this replacement works.

This is the third Flipsky Vesc6.6 that I have purchased and all 3 have been faulty out of the box. The slave esc is not recognized by the Pc via usb and undetected by the vesc tool when connected to the master esc. (And yes I made sure the CAN switch was on).I am very familiar with setting up and operating a VESC. And when I reached out to the support team they told me I’d need to flash the firmware using an st link. Ordered an ST link, and the day it was delivered the support team for this vesc emailed me again to say now they think my vesc is simply fried.If this were a $50 ESC this would be disappointing. But seeing as how this costs well over $200, this is unacceptable. They should be tested for quality before they are shipped to Amazon’s warehouse.At this point I can’t recommend Flipsky Vesc’s.

this product is new but it NEVER worked, never used it. but they offered to repair it "for free" but it's new so what happened here????....(by the way too expensive to not work)

Beware before ordering!!When your unit arrives dead, or in my case half dead as the hall sensors fail to be recognized by the vesc software. You're on your own, because no reply customer service.Well i probably geuss that 99% is ok on arrival but if it don't, money wasted.

First off, this fits perfectly against the heatsink from the original Evolve controller, (the full-size dual 6.6 does not.) I simply left the rubber heat transfer sheet in place, plopped this right on top of it, and had room to spare on the side for power connections. I am running sensorless at the moment, which requires that the board be moving forward (at least slightly) to begin accelerating. While this is annoying when waiting to cross a street, I've gotten used to it, and it will no longer be a problem once I wire up the hall sensors. Despite going from 175 to 200mm tires, acceleration is still brutal, and my range has increased from 20 to at least 22mi, or about 10% vs the previous setup, but this may be due only to the taller ratio, (in a car, a taller overall gear ratio = lazier acceleration, but better economy.) Braking performance is even better than with the original controller... Very easy to modulate anywhere between a slight drag and panic stop. Setup with VESC Tool was straightforward, and I was easily able to connect via their bluetooth adapter to the Android VESC Tool app too. I opted for a separate anti-spark switch, just in case it decided to fry, but given a do-over, I'd go for the plus version with this integrated to clean up wiring. These Flipsky VESC derivatives have the distinction of being AVAILABLE here on Amazon, the alternative being waiting weeks for shipment from afar, which scores bonus points. One last tip for anyone trying this in an Evolve board... There is plenty of room alongside the battery to locate both the remote and bluetooth receivers + their antennae. This gets them out of the way of the noise generated by the main power and motor phase wires, which can generate a massive field when accelerating or braking hard.
