What is the key rating used to determine if a LiPo battery can be transported on a flight?

• A. Weight
• B. Dimensions
• C. Watt-hours (Wh)
• D. Color

Answer: (C)

Energy content measured in watt-hours is what airlines use to decide if a LiPo battery can be transported. This rating directly reflects how much energy is stored and thus the potential risk if a battery were to fail in flight. Since Wh combines both capacity (in mAh) and voltage, it’s the standard measure used for transport rules rather than weight, size, or color. To convert from mAh to Wh, multiply the capacity by the nominal cell voltage (for a typical LiPo this is about 3.7 V) and divide by 1000. For example, 5000 mAh at 3.7 V is about 18.5 Wh. The higher the Wh, the tighter the restrictions, which is why Wh is the deciding factor for air transportation.
