Honestly, I felt bad to bother the sale of @Genex when I wrote my first post but when I’ve read “good vesc” I couldn’t resist to disagree. My 2 maytech V4.12’s are bad to the bone. I’ve tried them with 3 different FW. All with same settings and 20km test ride each. With FW 3.26 one motor got very hot and the other just warm. With FW 2.54 my master V4.12 had 20 ABS over current faults (135-150A) and the slave 1 DRV fault and 17 ABS over current faults, also sometimes weird behaviour.(see video below) and a lot of cut offs. Also when spinning the motors every 3-4 turns there was a strange noise and mechanical resistance on both motors (no matter which FW). With FW 2.18 and FW 3.26 i had no faults during riding, only on the bench some ABS current faults.
With my new V4.12 from @esk8 I never had any single fault nor any cut off nor any strange behaviour, the quality is top as expected, not a russian roulette like maytech! I use the same cables and settings on my new V4.12’s like before with maytech without problems.
Forgot to mention that both maytech V4.12 had the max current ramp step bug (also not easy to upload proper FW without bootloader), and one hall sensor pin had a cold solder joint, @JohnnyMeduse saw it with his eagle eyes on a picture.
@psychotiller @Genex here my evidence for the Maytech V 4.12 disaster:
I’ve ordered directly from maytech in china: 2x V4.12, 1x 6364 190kv and 2x steez remote. Including taxes and additional charges I’ve paid 590 € / 694 $ in the end. Beside the motor (but never tested) I lost a lot of money because I can’t use the V4.12’s and also want to swap the remotes because I love life, not death.
STEEZ remote has dangerous drop outs, here one example:
I was riding way too fast on the sidewalk approaching a street with about 35 km/h (strapped on my MTB) when my steez remote had a drop out and i couldn’t break, on both sides cars were driving. Well, I thought i’ll die or at least get bad injuries. I don’t know exactly what happened but with a ninja turn between driving cars i managed to get in opposing traffic without getting crushed and I could roll to a stop. People were looking like I’m a suicidal person. That was the most scary moment in my esk8 life yet.
I’ve claimed but never got an answer
I know I’m off topic because this is a sales thread and no discussion but I wanted to let you know why I am so much against maytech, this company is not acceptable for me, they should sell motors only!
Also I have no tree where money grows.
Again I’m sorry for bothering @Genex, I think you should make a new sales thread
