    adding a 12 volt converter

    Has anyone added a 48 volt to 12 volt converter wired in parallel to their BBS02 battery connection for lights?
    I have been getting an intermittant er30 code with this set up but am not sure if the code is from adding the converter or from something else.
    I have checked and rechecked all the connections except for the connections inside the case for the controller.
    BBS02 still works when the code comes on but screen goes blank and the pal can't be changed.
    The error occurs sporadically after riding a few miles.

    So I changed my display from the stock Bafang to the Luna Mini and everything works has it should.Looks like a bad display was the culprit.
