    basic power consumption question

    This is not a light build but I know you guys can answer the question :-)

    I have a 12VDC fan that draws .15A or 150mA. If I run in series 4 x 3.2v 18650 2400mAH batteries to power the fan. Will I be able to power the fan for 9600mAH / 150ma = 64 hours?

    Thanks,

    David

    Nope. Your battery will only still have 2400mAh capacity because they are series connected. About 16 hours run.
