Let‘s get started. First, what exactly does it mean to connect batteries in series or parallel? With a series connection, batteries link end-to-end by connecting the positive terminal of one to the negative terminal of the next battery. This increases the total system voltage, while maintaining the same capacity as an individual battery.
This increases the total system voltage, while maintaining the same capacity as an individual battery. In a parallel arrangement, the batteries sit side-by-side, with all positive terminals connected together and all negative terminals connected together.
Parallel wiring connects batteries side by side, linking all positive terminals together and all negative terminals together. This setup maintains voltage while increasing capacity. In parallel wiring, the total amp-hour (Ah) capacity adds up, but the voltage remains the same as a single battery. For example:
To wire multiple batteries in parallel, connect the negative terminal (-) of one battery to the negative terminal (-) of another, and do the same to the positive terminals (+). For example, you can connect four Renogy 12V 200Ah Core Series LiFePO4 Batteries in parallel. In this system, the system voltage and current are calculated as follows:
In a parallel arrangement, the batteries sit side-by-side, with all positive terminals connected together and all negative terminals connected together. This keeps the voltage consistent with an individual battery but sums the capacities together for a larger total capacity.
Do not connect batteries with different chemistries, rated capacities, nominal voltages, brands, or models in parallel, series, or series-parallel. This can result in potential damage to the batteries and the connected devices, and can also pose safety risks.
