Battery Management System — the small board bonded to the battery tabs. It protects the cell and reports capacity and cycle data to the phone.

Will the phone show a battery warning?

With a replacement board, usually yes, because it has not been authenticated for that phone. Reusing the customer's original board is what avoids it.

iPhone 11 Pro Battery Management System (BMS) Flex Cable.

The battery management board and connector flex — the piece that bonds to the cell tabs and reports to the phone. It handles cell protection and fuel gauging.

You need it when rebuilding a pack from a bare cell, or when the original board is damaged by liquid or a torn flex. Note that a replacement board has not been authenticated for that phone, so iOS will show the battery service warning; reusing the customer's original board is what avoids it.

For rebuilding a pack from a bare cell
Spot welding or tab transfer required

What this is used for

Rebuilding a battery from a bare cell
Replacing a corroded battery board
