Hello,
I have a brand new Bafang G311 kit that I purchased from Grin. I got it installed with their 10AH 36v bottle battery, standalone Baserunner contoller, and Cycle Analyst.
As soon as I got everything installed, with wheel circumference, poles, and PAS information set, the bike gets intermittent motor cutout, both with pedal assist and throttle. The CA does not power down, the motor just kind of blips off for an instant.
The speedometer is very erratic, moving so fast that it's hard to even register what speed is displayed. When I went to the "max speed" screen, I saw readings that would vary from 75-300mph. On the diagnostic screen the speed limiter was almost always capitalized, though I would estimate that I never got over 18mph. I've been through the settings several times and have tried the following hardware and software diagnostics:
-Tried second motor (I have another brand new G311 kit on hand)
-Tried second CA
-Tried second controller/battery (Reention downtube battery). This made it slightly better, but cutout still happened
-Adjusted Max Speed and DS gain values up and down. With the DS gain set to zero the diagnostic screen no longer popped a speed limiter, instead the power (W) began popping
-Adjusted Max Current, gain, Max power, gain settings up and down
-Confirmed integrity of Anderson connections to battery cradle
All these have been unsuccessful. I am concerned that this is somehow an ultra-noisy signal issue that I frankly am unsure how to rectify. I've done lots of ebike conversions but this is the first time venturing into the complexity level that the CA/Grin offers. I had hoped that their ready to roll kit would be a bit more...ready to roll but this has turned into a real head scratcher.
Thank you!
