Abstract: A dual port charging architecture is generally disclosed. For example, the dual charging architecture may include a first board portion having a first battery port configured to be coupled to a first set of battery terminals of a battery, a second board portion having a second battery port configured to be coupled to a second set of battery terminals of the battery, a connection portion electrically coupled between the first board portion and the second board portion, a first power path coupling a power input port of the second board portion to the first battery port via the connection portion, and a second power path coupling the power input port to the second battery port.
