How to Connect Lithium Batteries in Series and Parallel?
A series-parallel connection combines both configurations to increase both voltage and capacity. For example, connecting four 3.7V 100mAh lithium cells in a series-parallel
If you need any help with configuring batteries in series, parallel or series parallel please get in contact with one of our battery experts. Many brands of lithium batteries can not be connected in series or parallel due to their PCM or BMS configuration.
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.
) First connect in series according to the capacity of the lithium battery cell, such as 1/3 of the capacity of the entire group, and finally connect in parallel, which reduces the probability of failure of the large-capacity lithium battery module; first connect in series and then it is of great help to the consistency of the lithium battery pack.
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.
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.
Now you have two sets of three batteries, simply, connect two sets of three batteries in series and then connect the two set in parallel (as shown in fig above) where the overall battery capacity would be 600Ah and level of voltages would be 24V.
