1. A transport climate control system for use in a transport vehicle, the system comprising:
an electric load;
a controller; and
a battery pack voltage configurator circuit configured to provide an output voltage to drive the electric load, the battery pack voltage configurator circuit includes:
a first battery bank providing a first voltage and a first current,
a second battery bank providing a second voltage and a second current, and
a plurality of switches including a first switch, a second switch, and a third switch,
wherein when the electric load has a first load, the controller is configured to control the first switch and the third switch to be opened and the second switch to be closed so that the first battery bank connects to the second battery bank in series,
wherein when the electric load has a second load, the controller is configured to control the first switch and the third switch to be closed and the second switch to be opened so that the first battery bank connects to the second battery bank in parallel,
wherein when the electric load has a third load, the controller is configured to at least one of:
control the second switch and the third switch to be opened and the first switch to be closed, and
control the first switch and the second switch to be opened and the third switch to be closed,
so that the first battery bank or the second battery bank is disconnected from the battery pack voltage configurator circuit.
