This may or may not have been discussed here. If so I apologize.
I have a 75/100 pro V2. It came with FW6.02 75/300r2 installed which limits voltage to 72V max…
Because Im using a 20s 84V max battery I needed to use a no HW limits version FW. I upgraded to 6.05 75/300r2 NO HW limits.
I have to say that Im very impressed with this controller compared to previous versions made by FS. The motor commutates perfectly. Absolutly silent and powerful, The torque produced is so addictive. No desyncs, no cogging, no fault trips, Im getting 6800W peaks in a escooter hub motor. I love looking over data logs, Im seeing much more of that power is going into producing torque/speed than previous versions of both FW and HW. Basically its another way of saying the controller and FW give me the best efficiency yet.
Last week I stumbled upon a YouTube vid of a guy showing how to update the 75/100 pro V2 to FW 6.05. I wasn’t even going to watch it as I already upgraded and was happy but, I just had to read the video description. He had a link to FW 6.05 75/100 V2 not FW 6.05 75/300r2. Got me thinking maybe I screwed something up even thought I knew the stock fw was 75/300r2. After all, the designation of 75/100 V2 did make a lot more sense than 75/300R2… I just couldn’t help myself so I decided to give it a try.
I always start fresh after flashing FW, I reset everything to default then run the FOC wizard with exactly the same settings. After running the wizard I noticed the motor was noiser and things definitely were not as smooth/powerful as they were with the 75/300R2 FW… I would get many annoying timeout faults that I just couldn’t tune out. My data logs were showing less power. Quite honestly, not that long ago I would of found the performance awesome but after running with 75/300R2 for a short time I was spoiled by its performance. It was obvious that FW 6.05 75/100 V2 was not the correct version for the flipsky 75/100 pro V2. I reflashed back to 75/300R2, and repeated setup, this gave me my fix of the smooth/powerful performance that I crave.
Flipsky makes a 75/100 V2 and a 75/100 pro V2. I never had the Al heatsink 75/100V2 so I cant say for sure but it doesn’t take a stretch to assume that FW 6.05 75/100 V2 would be the correct FW for it.
The pro version has bluetooth integrated into the PCB but given the difference in performance there have to be other differences as well.
Could this be the filter/s b1996 mentioned above? I actually tried disabling filters as he alluded to but it didn’t seem to change performance. Im confused because Id think disabling filters would degrade performance back to what I was experiencing with my FW debacle explained above…
Basically for flipsky 75/100 pro V2 use FW 6.05 75/300R2… Even if it seems logical do not use 6.05 75/100 V2 on this specific controller. Even though that will work, it won’t be optimal… For me the difference to me is extremely palpable but remember I have a 10" hub motor. That said I cant see why those benefits won’t transfer to other motor types…
Im sort of a motor connoisseur lol, like an audiophile, very pick and striving for the best performance but never seem to get there no matter how much $$$$, gotta say if using the correct FW that unscratchable itch doesn’t bother me much. Withj new controllers and or FW updates Ive felt similar to this in the past but definitely not to this extent. With FW 6.05 75/300R2 It really does feel like my motor is tuned to perfection.
Jesus, just read after posting… Holy fuck! Long winded habits don’t die easily, it also sounds like Im a shill for FS, nope, just want to help others avoid problems.
