Plates that hold the cell in place and restrict movement. They contain openings to allow for electrical connections to be made between the cells on the top and bottom sides.  |

The main current-carrying conductors in the module. They create connections between the cells and usually take the form of nickel strips or metal sheets that are spot-welded to the modules.     |

Balance taps measure the voltage of the cells within a module. They measure voltage to see how balanced a module is. If a module is not balanced (meaning the cells inside are at different voltages), the cells inside the module are at risk of cell degradation and even an explosion. Keeping tabs on the voltage of the cells in the module is important to flag any potential risks and safety hazards. The balance taps are typically a wire attached to the busbars (via soldering or crimps) that travel to the AFE board, so the board can measure the voltage and charge the cell accordingly if need be.
