Uneven electrical current distribution in a parallel-connected lithium-ion battery pack can result in different degradation rates and overcurrent issues in the cells. Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections.
The cells are connected in parallel to fulfill higher current capacity requirements if the device needs a higher current, but there is not enough space available for the battery. That device can use the parallel configuration to fit high-current capability in a small space.
To wire multiple batteries in parallel, connect the negative terminal (-) of one battery to the negative terminal (-) of another, and do the same to the positive terminals (+). For example, you can connect four Renogy 12V 200Ah Core Series LiFePO4 Batteries in parallel. In this system, the system voltage and current are calculated as follows:
In contrast to batteries in series, batteries in parallel only increase the amp capacity rather than voltage. This means you can power your devices for much longer. Here are the advantages and disadvantages of connecting your batteries in parallel.
This will ultimately increase their duration (how long batteries can last) when powering equipment. But the increase in amp capacity also means that batteries in parallel take much longer to charge compared to those in the series combination. You can reduce the charge time by faster charging.
