The battery voltage needs to match the motor rating. The controller voltage rating needs to be the same or higher. The battery AH rating should be chosen based on the motor power rating ÷ motor voltage rating x 1hr. A 48V 500W motor should be paired with a 48V battery that has an AH rating of at least 500W ÷ 48V x 1hr = 10.4AH.
Amp-hour (Ah): This tells you how much energy the battery can store. The higher the Ah rating, the more energy is stored and the longer the electric bike can work. For example, a 10Ah battery pack means that it can supply 10 amps for 1 hour. It also means it can supply 1 amp for 10 hours, and any other variation using the same scale of 10Ah.
