Abstract
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.
