Ok, so am not looking for one for myself, am a business and have a problem with the ones I tested so far.
Kelly and Sabvoton - Pure crap, especially Sabvoton with terrible reliability issues and zero customer service, both have the slowest acceleration on the planet that I can see objects standing still passing me.
Yuyangking - Pure garbage, terrible acceleration, horrible lag keeping throttle on for a sec after releasing the throttle and the worst app ever, not to mention they are bigger than my refrigerator.
ASI - Well, it started as OMG they are the gods of the ebike controllers since when they are dialed right they are amazing BUT! and a big BUT! Setting them up takes forever with the most complex and horrible interface ever and of course they don't have a manual for nothing, all the settings are mega weird and not self explanatory at all, the support you get is from this Alan Hu guy from facebook who don't give a crap about you and after you buy $5000 worth of controllers he will act like a chinese supplier "yes yes come back 2 weeks me busy."
Plus, the harnesses are built by this guy and ASI themselves told me that he is the only one building them and they always have contacts falling apart and the cheapest chinese level work.
AND recently I've had a good friend have 3 BAC4000 controllers burn for no reason, flicking the switch and no power all of a sudden and this mystery is very concerning since he has to wait 3 month for ASI to check it and of course pay shipping to canada.
Bottom line, I tried to tolerate the fact that they are very expensive to make a profit for but I won't ever work with them as a business since they are too complex, no manual, no support, the warranty procedure ensures that you get your issue fixed a little before you die of old age and you get crap harnesses that cause never ending problems and you can't build one yourself as it's not some common connector you just crimp.
Then came Nucular - Already spent all of your attention reading about ASI so am gonna spare you some time by just summing it up.
GOD OF ALL EBIKE CONTROLLERS AND IF YOU SAY ONE BAD WORD ABOUT THEM YOU WILL HAVE BAD THINGS COME INTO YOUR LIFE!
Yes, that good.
BUT! unfortunately, even more expensive than ASI, especially because they don't have an app but an LCD which adds $70 more to the price tag of over $400 for the 24Fet version which is the only one I need for my market.
That means, $400+70+shipping+import tax+adding tax for selling it locally = No one will buy it for that price.
So...
Any ideas?
btw, also looking for non programmable simple sinewave controllers up to 55A with acceptable acceleration for my more simple market.
