[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 way is to look at Voltage (V) x Amp-hours (Ah) = Watt-hours (Wh), which refers to power output. The higher the Wh number, the more energy the battery contains, and the further it can travel.

• Watt-hours (Wh) calculation formula:
• Power Watt-Hours (Wh) = Voltage (V) × Amp-Hours (Ah)
• For example, if a lithium battery is labeled as 24V and 10Ah, its capacity is 240Wh.
• For instance, one 24V 20Ah = 480Wh is greater than > two 24V 6Ah = 288Wh
• Therefore, by looking at V, Ah, or Wh, we can make a real comparison.
