48V450W mid drive motor kit with LCD&PAS for ebike 3speed brushless gear motor | eBay
$470 USD including shipping, and I'm about to throw it in the trash. 30 day returns on E-Bay but no way I'm attempting to ship back 17 lbs of junk to mainland China. I told myself that this may not work; it's so close, yet so far away. Just a good controller away from working...but I need to 'guess' on the correct controller!
Controller that came with the kit (if you can even call it a kit) is Brainpower XLD 48V 450W 23A limiting. Problem is that the connection to the battery is horrible. Display that came with it does not work at all, and zero identifying marks on it. Throttle light lit up very weakly (lights for low / medium / high battery level indicator on throttle), throttle itself did not work; now even the light doesn't turn on.
Tried a few other controllers, nothing. I've read the 46.3-48.0V coming from my battery with a voltmeter, and the battery is also used regularly on a different hub drive e-bike, so I know for sure this is an electrical issue. The battery is fine. It's finding the correct display and throttle for matching up to ANY 48V controller that actually has a good electrical connection to the battery.
There is only one controller/display that turns on: KT 36V/48V controller 12 mosfet

The display is the familiar LCD-3. However, this one is a lame duck and is on it's last breath from the other ebike. As in it will not read any battery power and the throttle doesn't work, etc. And even if I buy a new controller/display that is the same as above, there is no guarantee anything will work with the motor, including the throttle. That's the real issue: how much more money should I throw at this before giving up.
