When creating a lead-acid battery bank with a higher voltage, like 24 or 48V you will need to connect multiple 12V batteries in series. But there is one problem with connecting batteries in series, and this is that batteries are not electrically identical. They have slight differences in internal resistance.
2. Initial Top-Balancing of a LFP battery Combining multiple Cells in series is required to achieve voltages higher than 3.2V. Balancing basically means bringing all Cells (in a battery) to same SOC. In this case, top-balancing means bringing all cells to 100% SOC. Bottom balancing means 0% SOC.
When a lithium battery is full, trying to charge it more will cause damage. Conversely, in a car the "12 V" lead-acid battery is usually just charged with a fixed voltage of about 13.6 V. At that voltage it will take a small amount of charge current even when full, but unlike with a lithium battery, this does the lead-acid battery no harm.

Interpreting a lead-acid battery voltage chart is key to understanding the health and performance of your battery. For a 24V system (comprising two 12V batteries in series), voltage readings will be roughly twice those of a 12V system, while 6V batteries (typically used in golf carts or solar setups) will have half the reading of a 12V battery:
