1. A marine battery configured to removably connect to a load to power at least one electric motor, the marine battery comprising:
at least one battery cell;
a bidirectional port configured to provide current output to the load from the at least one battery cell and to receive a charge current from a battery charger to charge the at least one battery cell;
a charge only port configured to receive charge current from the battery charger to charge the at least one battery cell;
a plurality of switches positioned between the bidirectional port, the charge only port, and the at least one battery cell; and
a battery control system configured to detect a connection status of at least one of the bidirectional port and/or the charge only port and, based on the connection status, to control the plurality of switches to transition the marine battery between a power delivery mode where current can flow from the at least one battery cell out of the bidirectional port, a charge mode where current can from the bidirectional port or the charge only port to the at least one battery cell, and a disconnected mode where current cannot flow between the bidirectional port or the charge only port and the at least one battery cell.
