Best controller?

[BDamari]

I've been looking all over the internet for a nice high quality sine wave brushless controller, I saw the Sabvoton, Infineon and the Adaptto but I always find mixed reviews.
Some always say that they're great and some say it broke after a few miles, and they should've bought the other one.
I'm looking for a relatively small sized controller for a 48-72v setup, doesn't have to be able to deliver more than 60A.
I'd love to get some suggestions, thank you.

Kelly Controllers haven't let me down yet.

I would go with the 80A Version: http://kellycontroller.com/kls7218s24v-72v200asinusoidal-brushless-motor-controller-p-1401.html

This one is rated for 50A continuous:http://kellycontroller.com/kls7212s24v-72v120asinusoidal-brushless-motor-controller-p-1348.html
But the problem is that I can't cool it fast enough. On the 80A Controller a slow 140mm PC case Fan was enough to cool it, but not good enough for the 50A version. For that Controller I might have to add a big heatsink with fan.

Also Kellys don't have overspeed or flux weakening, but otherwise pretty good for the money.

Do I have to cool these controllers?
I've seen many builds where the controller is mounted on the belly of the bike so maybe the wind will be enough to cool it down?
What about the Adaptto?

Well I had them mounted in a closed space inside my scooter. The 80A version should work fine with the wind cooling it, but I'm not so sure about the 50A version since it also has a smaller footprint.

So I would go with the 80A version.

I've been searching around the internet for a tiny very compact black controller that I saw the other day on the street, I'm pretty sure it's not Adaptto but I know it was Russian made, any ideas?

Could it be "phaserunner" you're talking about?

No, I found out it was custom painted in black, which can mean it can be any controller.

That last bit has me pretty bummed out, I didn't know about that until after I bought both of my KLS7230S's. Overspeed/flux weakening would allow me to gear my motorcycle a bit lower without losing top speed. Or just leave the gearing the same and go 90mph, lol.

Oh well, it got pushed back to a winter project, so maybe I can figure out something clever (or just figure out what kind of controller I'd like to upgrade to in the future).

Here is another option I know nothing about this controller
