    You have to wire the mess up until you make 200 volts .

    The fusion outage is 281V I wouldn't be afraid to try a whole pack like that in a Prius I've seen close voltages in a Prius . Probably won't hurt a thing If try it if I had the pack. There's some other things that plug up to the battery pack that may have to be sorted

    I'd just wire it up in a box in the hatch and see how it performs

    maybe rewrite the bus software to prevent an explosion, or maybe use the bus from ford
