Do you have a link for the controller which is supposedly plug n play. Someone said there is one with the Bird Juliet connectors in it and there is no need for cutting splicing the motor drive cables, hallsensirs, etc.
Were you able to get your battery BMS output stage bypassed? I'm doing a Bird 590 now for the first time. I have a 350watt controller with the S866 LCD display. I gotta crack open the battery box next to bypass the output stage if the bms.
Anyways,. If you have a link for the controller that is supposedly plug n play, please email it, or reply here.
Here's a link for a replacement headlight
