1. A vehicle comprising:
a battery cell configured to power the vehicle; and
a battery management system in communication with the battery cell, the battery management system configured to:
generate a first discharge current limit estimation for operating the battery cell over a prediction time;
generate a second discharge current limit estimation for operating the battery cell over the prediction time; and
operate the battery cell to power the vehicle using the one of the first discharge current limit estimation or the second discharge current limit estimation associated with a lowest magnitude.
