The master software and its parameters have to be adapted to the special battery
configuration. In exceptional cases a slave module may be modified to control three or four
cells. Controlling less than three cells is not possible.

The Master module covers the following functions:
 Communicating with the connected slave modules
 Providing and supervising time
 Measuring of the total current drawn from the battery
 Controlling the main power relay
 Switching of climatic equipment, e.g. fans, Peltier elements or similar devices
