A multi-battery flash charging system is described herein. The system is configured to reduce a power charging loss at a battery-operated device. This device includes multiple, distributed batteries. The process of reducing the power charging loss at the battery-operated device is achieved by generating a charge voltage at a charge voltage regulator that is required to be located externally relative to a housing of the battery-operated device. Reducing the power charging loss at the battery-operated device is further achieved by transmitting the charge voltage over a high resistance wire that couples the charge voltage regulator to the battery-operated device.

Flash charging parallel battery packs separated by a high resistance interconnect

A computer implemented method includes accessing a first status of a first battery pack interface coupled to a load via a first load switch and accessing a second status of a second battery pack interface coupled to the load via a second load switch. The first status and the second status are compared and the first and second load switches are controlled based on the comparing to balance remaining capacities of the first and second battery packs.
