Battery module / cell assembly
Organizes cells into a defined battery assembly where the architecture uses modules.
Within a compatible traction-battery design.
Mechanical support, electrical connections and sensing depend on the pack architecture.

A pack warning does not automatically identify a replaceable module.
Battery and drive components are assessed with system diagnostics and model-specific warranty and service guidance, not a universal expiry age.
High-voltage work requires trained facilities. A complete pack differs from a serviceable module, sensor or charging-port repair; no numeric quote is asserted.
Not every BMW battery architecture groups cells in the same way, so module serviceability must be verified.
