System and method of a mobile electrical system

A system, comprising:

• a motor/generator selectively coupled to a drive line of a vehicle, and configured to selectively modulate power transfer between an electrical load and the drive line;
• a battery pack;
• a DC/DC converter electrically interposed between the motor/generator and the electrical load, and between the battery pack and the electrical load;
• a covering tray positioned over a plurality of batteries of the battery pack, the covering tray comprising a connectivity layer configured to provide electrical connectivity to terminals of the plurality of batteries, and wherein the connectivity layer comprises a charging circuit allowing each of the plurality of batteries to be discharged individually;
• a plurality of battery microcontrollers, each of the plurality of battery microcontrollers associated with a corresponding one of a plurality of batteries of the battery pack;
• and
• a primary DC/DC controller configured to command operations of the DC/DC converter;
• wherein the plurality of battery microcontrollers are operationally coupled to the primary DC/DC controller.
