Understanding the Lifespan of 4 Parallel 12V 100Ah Lithium Batteries

Lithium batteries have become a preferred choice for energy storage due to their reliability, long lifespan, and efficiency. When discussing the lifespan of a configuration such as four 12V 100Ah lithium batteries connected in parallel, it is essential to consider various factors such as usage, load, and environmental conditions. This article explores the basics of parallel battery configurations, factors influencing runtime, and highlights OKMO's LiFePO4 battery system capabilities.

Basics of a Parallel Connection

In a parallel connection, batteries of the same voltage are connected together to increase the total capacity while maintaining the original voltage. For instance, connecting four 12V 100Ah batteries in parallel results in a total capacity of 12V and 400Ah. This setup is ideal for applications requiring extended runtime without increasing voltage.

Calculating Battery Runtime

The runtime of a battery system depends on the total capacity and the load connected to it. The formula to estimate the runtime is as follows:

For a 12V 400Ah system, if the load draws 10A:

If the load increases to 50A:

It’s important to note that these calculations are theoretical and assume 100% depth of discharge (DoD). In practice, it is recommended to limit DoD to around 80% for lithium batteries to extend their lifecycle.

Factors Influencing Battery Runtime

Several factors affect the runtime and performance of lithium batteries:

1. Load Profile: A higher current draw reduces the runtime significantly. Maintaining an optimized load can enhance efficiency.

2. Temperature: Lithium batteries perform best between 15°C and 35°C. Extreme temperatures can reduce capacity and performance.

3. Battery Age: Over time, the battery's capacity decreases due to wear and tear.

4. State of Charge (SoC): Charging and discharging rates impact the battery’s available energy.

5. Balancing and Maintenance: Proper balancing of cells and regular maintenance prevent uneven aging and ensure longer runtime.
