In simple terms, wiring batteries in series raises the system voltage but keeps the amp-hour (Ah) the same, while wiring in parallel keeps the voltage the same but increases total capacity, so your choice should always start from “do I need higher voltage or longer runtime?”

Should you connect a battery to an inverter in parallel?
Many people prefer to connect batteries and inverters in parallel. This is because there is less limitation on how many batteries you can connect to your inverter at once. The other thing to consider is your battery charger. The bigger your battery capacity and overall amperage, the more powerful your battery charger needs to be.
Should Inverter Batteries be wired in series?
If you decide to wire your inverter batteries in series it will increase the voltage and limit how many you can hook up to your inverter. Many people prefer to connect batteries and inverters in parallel. This is because there is less limitation on how many batteries you can connect to your inverter at once.
Can you connect a battery in parallel?
Connecting batteries in series increases the voltage (V), while connecting them in parallel increases the capacity (amp-hours, Ah). The total power (measured in watt-hours, Wh) available from the batteries remains the same in both configurations; it’s the delivery—voltage and current—that differs. Can you wire different batteries in parallel?
What is the difference between a series and a parallel battery?
Batteries wired in series will add their voltages while the current capacity stays the same. Conversely, batteries wired in parallel will have their current capacities added together while their voltage remains the same.
