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.
To safely connect 12V lithium batteries in series, the following options should be considered: Customized high voltage protection board: 48V system requires a protection board with a voltage of at least 80V, and the MOSFET selection must match the total voltage.
If you have two 12V, 200Ah hour batteries and you need 12V system for installation. Simply, connect both of the batteries in parallel where the overall battery capacity would be 400Ah and the same voltage level i.e. 12V. Keep in mind that battery discharge quickly in parallel as compared to series batteries connection.
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.
This combined setup is necessary because relying solely on one method may not meet the power requirements. By combining series and parallel connections, battery packs can be customized to deliver the desired voltage and capacity. For simplicity, battery packs are labeled with abbreviations : “S” for series and “P” for parallel.
For example, 4 pieces of 3.7V lithium batteries connected in series can get an output voltage of 14.8V, but the capacity remains unchanged. Series connection is the most common method to make the battery pack reach the required operating voltage. Series connection is the best choice when you need more voltage rather than more capacity.
