Abstract

A power management system and method are disclosed. The system can be a high availability power delivery system. The system can be GPS tracked. The system can have multiple batteries, multiple input power sources, and multiple loads. The system can switch between the multiple batteries and the power source to deliver power to the load. The system can ensure there will always be an input power source to power the load.
