    Hello,

    I am working on a class project and need help on how to regulate a 14.8v dc battery down to 12 volts and at least 6amps of current.

    Any help would be awesome,

    Mike

    Is this something that's going to be used in an automotive application?

    Usually, the batteries measure roughly 12.7v when charged, and the system voltage is roughly 13.8v-14v when the engine is running.

    What are you powering that requires 6A current?

    it is going to be an autonomous hovercraft and the levitation fan has a 5.5 amp draw.

    OK. It's a brushed DC motor then, right?

    Probably the easiest and most efficient way would be to use a PWM circuit. PWM stands for Pulse Width Modulation. This works very well for inductive loads like motors.
