How to balance the voltage of batteries
Cell balancing is the act of making sure all cells in a battery are at the same voltage. When building a lithium-ion battery, the process involves connecting many cells together to form a singular power source. In ideal circumstances, brand-new cells will all be at the same voltage level. This, however, is not always the case. There are several ways this can be achieved. Batteries can be top-balanced or bottom-balanced. They can be actively balanced or passively. Top balance is when the cell groups in a battery are balanced during the charging process. There are many applications that are well suited for top balancing, but the best example of such in. To manually bottom balance a battery pack, you will need access to each individual cell group. Let's imagine that we have a 3S battery and the cell voltages are 3.93V, 3.98V, and 4.1V. Bottom balancing, as you would expect, is pretty much the opposite of top balancing. Bottom balancing is used when getting the absolute most out of each discharge cycle is the most important.

What happens if a battery is not balancing?
Without balancing, when one cell in a pack reaches its upper voltage limit during charging, the monitoring circuit signals the control system to stop charging, leaving the pack undercharged. With balancing, the Battery Management System (BMS) continuously monitors voltage differences and upper voltage limits.
