Converting watt-hours to milliamp-hours takes one step: divide by the voltage. Ah = Wh \/ V, and mAh = (Wh \/ V) * 1000.<\/p>\n\n\n\n

The same 100 Wh battery equals 27 Ah at 3.7V, but only about 2 Ah at 48V. That is why voltage matters as much as the energy rating.<\/p>\n\n\n\n

Use the calculator below, or follow the worked examples.<\/p>\n\n\n\n\n\n\n\n\n\n
