Battery Welding Process: Expectations vs. Reality
The positive and negative connectors that transport the electrical current through the cells are known as battery tabs or terminals. Each tab is connected to a busbar (or collector plate) on the module, which redistributes positive and negative current to new terminals. The battery pack is made up of several modules connected in the same way.
