How To Connect Batteries In Series and Parallel
If you have two sets of batteries connected in series, you can wire both sets into a parallel connection to make a series-parallel battery bank. In the images below we will walk
For systems requiring higher voltage, our 24V 100Ah model offers a versatile option, though for parallel connections, two 12V models remain a popular choice. Connecting two 12V lithium batteries in parallel is a straightforward process that can significantly enhance your system's capacity while maintaining a stable 12V output.
So, if you have two 12V batteries, each with a 100Ah capacity, connecting them in parallel will give you 12V at 200Ah. Why Does Parallel Connection Work? In a parallel connection, the current (amperage) is shared between the batteries, meaning they work together to power your system for a longer period.
This parallel wiring method is essential for 12V systems, including 12V charge controllers and inverters. Therefore, two or more solar panels and batteries (each rated at 12V DC) are connected in parallel to maintain system voltage while increasing current capacity.
Increases Capacity: The total amp-hour (Ah) rating is the sum of the individual batteries' capacities. For instance, connecting two 12V 100Ah batteries in parallel yields a 12V 200Ah system. Enhances Runtime: More capacity means longer operating time for your devices or appliances. Why Choose Lithium Batteries for Parallel Configurations?
