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.
Lithium battery parallel connection is to connect the positive poles of multiple batteries together, and the negative poles together, so that the total capacity can be increased while keeping the voltage unchanged.
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.
Always use identical batteries—same voltage, capacity, and type. Mixing them can cause uneven charging, a risk I avoid at Minghong Power by offering matched lithium packs. Proper wiring also prevents hazards, ensuring reliable performance for your setup. How Do You Connect Two Batteries in Series and Parallel?
Connecting Batteries in Parallel Pros: Increased Capacity: When you connect batteries in parallel, their capacities (mAh or Ah) add up, providing longer battery life. Same Voltage: The voltage remains the same as a single battery, which can simplify compatibility with your device or system.
In a parallel connection, the batteries are linked side-by-side. This configuration keeps the voltage the same but increases the capacity. For instance, connecting two 3.7V 100mAh lithium cells in parallel will result in a total capacity of 200mAh while maintaining the voltage at 3.7V.
Nominal voltage is the standard operating voltage of a LiFePO4 battery pack cell, typically 3. In series, multiple cells increase voltage (e. This ensures compatibility with solar inverters or EV motors.
