FAQs about Cylindrical lithium battery series connection skills
Why are lithium batteries connected in series?
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.
When should a lithium battery be connected in series?
You should connect lithium batteries in series when your device requires a higher voltage than a single battery can provide. For example, if your device operates at 7.4V, connecting two 3.7V batteries in series would be appropriate. This setup is commonly used in applications like electric scooters, drones, or other high-voltage devices.
What is a series battery connection?
A series connection involves linking batteries end-to-end to increase the total voltage while keeping the same capacity (measured in milliampere-hours, or mAh). For example, connecting two 3.7V 100mAh lithium cells in series will yield a total voltage of 7.4V, but the capacity remains 100mAh.
What are the characteristics of a series battery connection?
Characteristics of Series Connection: Voltage: Sum of individual voltages (e.g., 3.7V + 3.7V = 7.4V). Capacity: Remains the same (e.g., 100mAh). Usage: Suitable for devices requiring higher voltage. Connecting Batteries in Series Pros: Increased Voltage: Connecting batteries in series adds their voltages together.
