Lead-acid battery bank balancing. 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.

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.

Lead Acid cells do not exceed 100% SoC (State of Charge) when overcharged but will outgas hydrogen at this point. Battery cells at lower SoC will continue to charge until they also reach 100% SoC. All cells will stop charging (and begin outgassing) at 100% SoC. This same feature is why lead acid batteries do not require cell balancing (see below).

Learn MoreThere are two main methods for battery cell charge balancing: passive and active balancing. The natural method of passive balancing a string of cells in series can be used only for lead-acid and nickel-based batteries. These types of batteries can be brought into light overcharge conditions without permanent cell damage.
One of the prime functions of this system is to provide the necessary monitoring and control to protect the cells from situations outside of normal operating conditions. There are two main methods for battery cell charge balancing: passive and active balancing.
With passive and active cell balancing, each cell in the battery stack is monitored to maintain a healthy battery state of charge (SoC). This extends battery cycle life and provides an added layer of protection by preventing damage to a battery cell due to deep discharging over overcharging.
Lead-acid batteries are widely used in a broad range of industries and applications. The telecom industry uses a series stack of four lead-acid batteries to provide a 48V stack.
The only way to ensure that all the batteries in a stack are at the same voltage is by employing a balancing solution in which overcharged batteries shed excessive charge, while undercharged batteries are given extra charge.
In all the examples, two or more lead-acid batteries are connected in series. When a single lead-acid battery in the stack fails, all the lead-acid batteries in the series stack need to be replaced to maintain battery stack performance. This is a considerable expense.
