The series and parallel connection of lithium batteries is a key technology to increase voltage and capacity, but it also contains safety risks. This article will analyze in detail the principles, methods and precautions of series and parallel connection of lithium batteries to help you avoid potential risks and build a battery system correctly.
Before proceeding with the parallel connection of lithium batteries, it is crucial to keep the following precautions and considerations in mind: Battery Compatibility: Ensure that all the batteries you plan to connect in parallel have the same voltage and capacity ratings. Mismatched batteries can lead to imbalances and potential damage.
Specific principles must be followed when charging parallel lithium battery packs: Use a matching charger: The voltage must be suitable for the nominal voltage of the individual batteries. The current setting is reasonable: usually 0.2-0.5C of the total capacity after parallel connection.
If your load requires more current than a single battery can provide, but the voltage of the battery is what the load needs, then you need to add batteries in parallel to increase amperage. Wiring batteries in parallel is an extremely easy way to double, triple, or otherwise increase the capacity of a lithium battery.
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.
Parallel lithium batteries have many advantages, including increased capacity, enhanced power output, and improved overall performance. When multiple batteries are connected in parallel, their individual ampere-hour (Ah) capacities add up, resulting in a higher total capacity.
