Battle Born explains its battery thermal safety design involves inserting a thermoplastic between the bus bar and terminal to reduce pressure during overheating events, forming an aluminum oxide layer that interrupts current flow. This explanation addresses user-reported issues of poor contact and overheating but faces skepticism due to field failures showing loose connections from thermal creep, raising questions about the design's effectiveness and necessity over simpler solutions like a thermal fuse.
