Linking 12-volt batteries in series provides a convenient method for constructing higher voltage battery systems, such as 24V, 36V, and 48V. It is advisable to balance the batteries in series, also referred to as voltage matching, by charging each battery individually prior to linking.

Benefits of Balancing Batteries
When you balance batteries before connecting them, the system’s total capacity will be higher. This means more runtime for trolling motor, solar battery bank, or whatever you are powering.
The stress of discharging to empty primarily contributes to reduced battery lifespan.
By balancing the voltage across the series-linked battery configuration, the stress is evenly distributed among all batteries, thus extending the lifespan of each unit. Balancing batteries prior to connecting them in series optimizes performance and maximizes battery lifespan. This practice is essential to achieving maximum system output and longevity.
How to Balance Your Marine Batteries
For optimal results, use a 12V LiFePO4 compatible charger to individually charge each battery unit until it reaches 100% charge. This voltage balancing procedure should only be performed once prior to setting up the system. Subsequently, the entire system can be charged using the higher-voltage charger.
Upon completing individual battery charging, the units can be connected in series to establish a higher voltage system, such as 24V, 36V, 48V, etc. Implementing this configuration results in a balanced battery system.
Going forward, you should use a higher-voltage LiFePO4 charger to charge the complete battery series configuration. This approach increases efficiency by charging a 48V system with a 48V LiFePO4 charger. Do not use a higher voltage charger, such as 24V, 36V, or 48V, to charge an individual 12V battery pack.
How Often Should You Balance Your System?
You should perform voltage balancing procedures on batteries after extended storage periods exceeding three months or in the event of a noticeable decline in performance. Annual voltage balancing of the battery units is recommended as a preventative measure to enhance the battery system’s overall lifespan.
