  1. That BEC, you multiplied the input voltage by the output current.
    You should have multiplied the 15A by the 6.5V output voltage, that’s still a low of power, 97.5W. The input voltage of 50.4V is 12 lithium cells in series.

    The blue thing, that’s a brushless speed control for an RC car.

  2. Have you tried to put on cell over another to see what the combined output might be?

  3. This web site truly has all the information and facts I wanted concerning this subject and didn’t know who to ask.
