I've been quite happy using my Q100H (front wheel motor) for the last few years with the controller it came with from bmsbattery.com (S06S), but now I'd like to change the controller to run on 48V. I want a new controller for 3 reasons: first I'd like to get a better battery and have it work on both my bikes, secondly my existing controller overheats after about 1k feet of climbing while the motor isn't even warm, so I'd like a higher amperage controller. And third, a small speed and power boost for the Q100H would be a nice bonus. Ideally I want a controller rated for around 20 amps that I can limit to 15-17 amps (by modifying the shunt?) to eliminate my overheating problem entirely.
Is anybody using a Q100H at 48 volts without any issues? I was going to order a KU93 from bmsbattery.com but I found this thread about the new controllers shutting off at higher throttle:

The controllers from e-crazyman were also suggested, and this may be a decent option (though no PAS input):

I also have a question on Q100H maintenance. I've ridden it 2500 miles and over the last 500 or so, it has gotten noticeably louder (maybe 50% more, though still very quiet compared to my MAC setup) along with an increase in vibration. Is it worth disassembling it? I can't figure out how to get the case off. I have a gear puller but I want to be sure how to proceed before I start forcing things.
