Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh. Such a configuration is called 4s2p, meaning four cells in series and two in parallel. Insulating foil between the cells prevents the
An EV battery pack comprises multiple modules, each containing many cylindrical or pouch-style lithium-based batteries. Cells are arranged in a combination of series and parallel configurations to create an output of 400V or 800V. The current trend is towards 800V packs, the key reason being the ability to achieve a quicker charge cycle for a given current.
