Wiring batteries in series is a method of connecting batteries to increase the voltage while maintaining the same amperage. This is achieved by connecting the positive terminal of one battery to the negative terminal of the next battery, and so on. The voltage of the series circuit is the sum of the voltages of the individual batteries.
Wiring batteries in series has several benefits, including increased voltage, longer runtime, and reduced cost. Increasing the voltage of a battery pack can make it suitable for powering higher-voltage devices or applications. Wiring batteries in series can also extend the runtime of a battery pack by providing a greater total capacity. Additionally, wiring batteries in series can be more cost-effective than purchasing a single battery with the same voltage and capacity.
