Linking 12 Volt batteries in series is an easy way to create higher voltage 24V, 36V and 48V battery systems. Before linking batteries in series however it is helpful to first charge each battery individually. This is called balancing batteries in series, also known as voltage matching. Balancing batteries in series has two big benefits: The total capacity of the system will be higher. This means more runtime for your golf cart, trolling motor, solar battery bank, or whatever you are powering. The lifespan of each battery will be longer since the stress of running to empty is evening shared by all batteries instead of a single battery. Dakota Lithium Iron Phosphate (LiFePO4) batteries have a very long lifespan (typically...
