It’s both Volts (V) and Amp Hours (Ah) that matter, because together they determine the total energy a battery can deliver, measured in Watt-hours (Wh), which is simply volts times amp-hours. The voltage determines how much electrical "pressure" is available to push current through the motor, while the amp-hours indicate how much charge the battery can store.
