Do not connect batteries with different chemistries, rated capacities, nominal voltages, brands, or models in parallel, series, or series-parallel. This can result in potential damage to the batteries and the connected devices, and can also pose safety risks.
For example, you can combine two pairs of batteries by connecting them in series, and then connect these series-connected pairs in parallel. This arrangement is referred to as a series-parallel connection of batteries. In this system,
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:
This indicates thicker cables and more voltage drop. Batteries can be connected in a mixture of both series and parallel. This combination is referred to as a series-parallel battery. Sometimes the load may require more voltage and current than what an individual battery cell can offer.
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.
It’s worth noting that connecting batteries in a series doesn’t increase ampere capacity. The batteries are tethered end-to-end by connecting the positive terminal of one battery to the negative terminal of the next one. This way the voltage of the connected batteries is added together.
