    How to determine wiring of DC motor controller

    Disconnect the motor and controller.Power on the controller alone and measure the 4-pin connector's pins to identify the power supply connections. Look for a steady 24V DC output between two pins.

    Battery management circuit

    I cannot see any balancing circuit in the schematic. Add a balancing circuit for the 6 cells, either using an external IC (e.g., BQ76920 or BQ76200) or discrete components. Your battery pack is a 6-cell LiFePO4 configuration (3.2V nominal per cell), meaning a total nominal voltage of 19.2V and a...
