HOW TO – SERIES WIRING FOR 24V/48V UPS AND INVERTERS

Wiring LiFePO4 batteries in series is a common way to increase the voltage of a battery bank and create a higher voltage system. By connecting multiple batteries in series, the total voltage of the battery bank is equal to the sum of the individual battery voltages.

For example, to create a 24V system, you could wire two 12V LiFePO4 batteries in series. The positive terminal of one battery is connected to the negative terminal of the other battery, and the remaining positive and negative terminals are connected to the load or to the system's charging source. The total voltage of the battery bank is then 24V.

To create a 48V system, you would wire four 12V LiFePO4 batteries in series. The positive terminal of the first battery is connected to the negative terminal of the second battery, and so on, until the positive terminal of the fourth battery is connected to the load or charging source. The total voltage of the battery bank is then 48V.

It's important to note that when wiring LiFePO4 batteries in series, you need to ensure that the batteries are well-matched in terms of capacity, voltage, and internal resistance. This will help to ensure that the batteries are balanced and that they will deliver consistent performance and longevity over time. Additionally, a battery management system (BMS) is typically used to monitor the individual battery voltages and ensure that they are charged and discharged safely and efficiently.
