Hi All,
This forum got us pretty far in our first electric bike build, but it seems we may have hit a hurdle. I've tried to look for a similar problem and couldn't find anything, unless the search terms I used weren't correct.
The battery we're using is a 21S 18650 pack running a Cromotor V3, an 18fet infineon based controller with a CAv3DP. Current is set to 60A on the controller and 60A on the CAv3. R shunt is 1.232ohms
Tried different phase combinations, and about to try different hall sensor combinations, although all the wire colours matched up as per this post http://endless-sphere.com/forums/viewtopic.php?f=2&t=48099
Need to test the voltage off the throttle plugged into the CA, but it does register on the display. The other thing is once the CA is reset and turned on, regen just continues to climb till it hits 999.99%. There are some images below.
The motor doesn't freewheel smoothly, and on every rotation I manually pedal when it's off the ground, the CA display brightness flickers. Not sure what's going on here and any help is appreciated.
No throttle applied
