A battery pack includes an enclosure assembly, a sensitive battery component housed inside the enclosure assembly, and a sacrificial battery component packaged outside of the enclosure assembly. The sacrificial battery component includes a pre-defined failure area configured to minimize the transfer of impact loads into the enclosure assembly. The sacrificial battery component may plastically deform and break at the pre-defined failure area in response to an impact loading event that exceeds a pre-defined load threshold of the pre-defined failure area.
