12V 200Ah LiFePO4 Batteries in Series and Parallel
If your battery system needs more voltage and ampere hour (Ah) capacity than one single battery can provide, connecting multiple batteries in series or parallel can help you reach your desired output. However, knowing when and how to use these configurations is important to ensure optimal performance and maximum longevity for your battery pack. Let’s take a look at how and when to connect batteries in series and parallel, as well as the effects of each method on your system’s overall energy production (measured in watt-hours).
When battery cells or batteries are connected in series, their voltages add together but their Ah capacities remain the same. For example, two 12v 200ah lifepo4 battery wired in series would output 24 volts with a combined 200 Ah capacity (12 volts + 100 volts = 24 volts). The same is true for batteries connected in parallel; their total voltage increases, but their individual amp-hour (Ah) ratings stay the same.
Whether you are using a single battery or multiple, it is important to avoid mixing battery chemistries when wiring them in series or parallel. This can cause the batteries to discharge and charge at different rates, leading to premature failure. For this reason, it is recommended to always use batteries with the same voltage and Ah rating when connecting them in either series or parallel.
Connecting Multiple 12V 200Ah LiFePO4 Batteries in Series and Parallel
It’s also important to keep in mind that the older a battery gets, both in terms of age since manufacture and usage, the more it loses its ability to hold its original voltage and Ah capacity. This is especially the case if the battery is regularly used for high-demand applications, such as an RV or solar power setup, where it will often be charged and discharged to its peak performance.
In these situations, replacing an old battery with a new one may help restore its original voltage and amp-hour capacity. The same is not true for connecting multiple batteries of the same age to each other in series; doing so can lead to over-discharge and over-charging damage to the other batteries.
The best way to maintain the lifespan of your battery system is to properly monitor its performance and condition on a regular basis. This includes testing the resistance between each battery and its BMS connection, as well as performing a watering regimen. It’s also a good idea to replace your battery at the first sign of visible degradation or if you have been using it for high-demand applications.
