[Battery Selection] Single battery or Two Batteries ?

To calculate battery capacity, we don't look at the number of batteries (one/two). The most practical thing is to look at voltage (V) x capacitance (Ah) = watt hour (Wh), that is, Watt per hour: refers to the power output. The larger the Wh number is, the more energy the battery contains and can travel further.
