    help installing andersons on controller

    Hullo all. I have just received a 36v 12a lifepo4, persino controller (sensorless) and a bafang jewel. The battery and charger came pre-equipped with andersons, which is what I wanted. The controller, however, has a strange three pronged connector for the power-in (a plastic housing with what...
