Can a lithium battery pack be used in series?
In solar energy storage systems, for example, multiple lithium battery packs are often connected in series to store the energy generated by solar panels. The higher voltage
Connecting Lithium Solar Batteries in Series: To connect lithium solar batteries in series, you simply link the negative pole of one battery to the positive pole of the next battery. This ensures that the same current flows through all the batteries. The total voltage of the series connection is the sum of the individual voltages.
Connecting Lithium Solar Batteries in Parallel: When connecting batteries in parallel, the positive terminals are connected together, and the negative terminals are connected together. The ampere-hour capacity of the individual batteries adds up, while the total voltage remains the same as the individual batteries.
The main purpose of connecting lithium solar batteries in series is to increase the output voltage. By adding up the voltages of the individual batteries, you can power devices that require higher voltage amounts. For example, connecting two 24V 100Ah batteries in series will result in a combined voltage of 48V while maintaining the same capacity.
Lithium batteries are connected in series when the goal is to increase the nominal voltage rating of one individual lithium battery - by connecting it in series strings with at least one more of the same type and specification - to meet the nominal operating voltage of the system the batteries are being installed to support.
