1. A power system using multiple, modular battery packs to generate an output electrical signal, the power system comprising:

  • a plurality of modular battery packs, wherein each of the plurality of modular battery packs comprises;

    a first housing;

    a plurality of battery cells enclosed in the first housing;

    a first interface that communicates information associated with the modular battery pack; and

    a second interface that transmits power from the plurality of battery cells;

    a power module comprising;

    a third housing that has a same form factor as the first housing of at least one of the plurality of modular battery packs;

    a waveform generation circuit enclosed in the third housing; and

    a processing system enclosed in the third housing that is configured to;

    receive the information from each of the plurality of modular battery packs, the information indicating electrical waveform characteristics for respective power received from each of the plurality of modular battery packs;

    cause the waveform generation circuit to aggregate the power received from each of the plurality of modular battery packs according to the respective electrical waveform characteristics; and

    cause the waveform generation circuit to generate the output electrical signal based on stored parameters wherein the stored parameters define at least a voltage of the output electrical signal; and

    a second housing configured to removably receive the plurality of modular battery packs and removably receive the power module, the second housing comprising;

    a plurality of openings in a front face of the second housing into which the plurality of modular battery packs and the power module can be inserted;

    a backplane on a back face of the second housing that is opposite of the front face, wherein each of the plurality of modular battery packs and the power module connect to the backplane when inserted through the plurality of openings.
