Controller question

[Sappho1949]

I have a Bafang bbs02 48v 750w, with UART protocol. I need a new controller, having trouble finding one specific to the UART protocol. Can the controller from a bbs02 motor with CAN protocol be used as a replacement for the motor that I have with UART protocol? The new versions of the controller all have connections for a headlamp, which my motor doesn’t have, as it seems to be an older version. It was purchased new from Bafang around 2016 or 2017. Any help would be appreciated!

No, the canbus won't work with your display. But it doesn't seem that hard to find a UART controller. This one says it will work with BBS02's newer than 2015. You don't have to use the light connector. https://www.amazon.com/BAFANG-Contr...8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1

I have only used a light kit once in the last eight or nine years. What I do is chop the light connector, strip off 5mm of outer insulation, pull the three wires back, and seal it with marine grade 1/4" heat shrink. It makes it neat and prevents a battery draining short. On those motors there is no good way to completely hide it. Maybe a slim zip tie around the entire base of the wires at the controller to prevent it from flopping. Some motors have a small hidden compartment with a cover plate for things like that. The second photo is a BBS02 build. The weird wire to the left is the dropper.
