why does Dr Prius app show only 14 modules when I thought there was 28?

    does each bar in the Dr Prius app equal two modules?

    Yes.
    There are 28 individual modules, each 7.2 volts nominal. Typical in use voltage 7.5-8.x volts.
    Each pair of modules forms a block, which is measured for overall voltage.
    There are 14 blocks, each consisting of 2 modules => nominal voltage 14.4 volts. Typical "in use" voltage 15-16.x volts
