1. A method of establishing a direct electrical bond between a bonding connector of a contact plate and a battery cell in a battery module, comprising:
placing the bonding connector into contact with a terminal of the battery cell;
applying a hold-down plate to secure the placed bonding connector onto the terminal, wherein the hold-down plate includes protrusions that are configured to be placed over a set of bonding connectors of the contact plate such that downward force results in the set of bonding connectors being bent downwards so as to be pressed down onto a corresponding set of terminals; and
laser-welding, during the applying, the placed bonding connector to the terminal.
