Hey, @reelism I’ve also just acquired an “MKSESC 75100” from AliExpress and am wondering what firmware your device came with from the factory? Mine came with “Fw: v6.02, Hw: MKSESC_75_100_OLD” and I am curious if you have had any other issues using the v6.05 firmware for the 75_100_V2 hardware? Also, it appears my board is a slightly different, maybe newer, revision of the PCB, images below.
EDIT: Check my reply below for an update on firmwares: How to update firmware on the Flipsky 75100 & 75200 FOC ESC - #454 by JdogAwesome
EDIT 2: Just ran a test with this ESC and I am very impressed! Pulling 2-3kW for ~2 minutes showed only a ~14C increase from 32C to a max of 46C. Video of the run here: https://www.youtube.com/watch?v=1ZvEmQOlLgg
NOTE: I am happy to see the TO-220 FETs soldered to a thick aluminum PCB. I’d imagine this will provide much better thermal conductivity than the kapton insulators of the older Flipsky units. And nearly the entire top and bottom of the PCB is well conformal coated, another plus. However, these floating capacitors are crazy, probably going to design a brace for them, or epoxy pot the entire thing.
