Moving forward with calculating the battery size for a 3000W Ebike, consider these key factors, which include voltage and amp-hours (Ah).

Voltage represents the electrical potential difference or the force behind the current flow. High voltage battery provides more speed and less voltage battery offers low speed.

Whereas, Amp-hours indicate your e-bike’s battery capacity or the amount of energy it can store in one single charge. A higher Ah battery gives more range and vice-versa.

When you multiply these two i.e., VxAh. You will get watt-hours.

Watt hours = Voltage (V) x Amp-hours (Ah)

Step 3: Calculating battery size using the motor’s wattage ratings

Finally, to calculate the battery size for a 3000w ebike, you would need to determine the current (in amperes) required by the motor to perform at its optimal level. So for that, divide the power (in watts) of the e-bike by the voltage (in volts).

For example, a 3000W e-bike with a voltage of 60V would require a current of approximately 50Amps (3000W ÷ 60V = 50A).

Congratulations! You have successfully determined the current flow needed for your 3000W e-bike battery. So, after establishing that value, consider the range or distance you want to ride on a single charge.

The reason is that a larger battery capacity, represented by higher amp-hours, provides a longer range before requiring a recharge.

Some essential things to consider are the battery management systems (BMS ) that usually come integrated with the pack. Since it ensures protection from overcharging or discharging and helps maintain the riding life of your e-bike battery.

Well, most electric bikes with 3000w motors have 60v batteries and some superfast ebikes have 72v batteries.

Check the voltage requirement of your 3000w motor. If it is asking for 60v, opt for a 60v battery. If it is asking for 72 volts, pair it with a 72v battery. You just have to match the voltage of the battery to the motor’s voltage.

And the next step is to decide the Amp-hours of the battery. Always select the Ah equal to the controller’s capacity. If the controller’s capacity is 50Ah, go with a 50Ah battery or less. Don’t go beyond this limit.

Amp-hours have nothing to deal with the e-bike’s speed. It only affects range. If you select a battery with higher Ah, you will get more range and vice-versa.

So, what size ebike battery do I need for a 3000w electric bike, a battery pack of 60v with 30Ah, 40Ah, or 50Ah is enough.

Here is the table showing the expected range for a 60v battery with different AHs when paired with a 3000w electric bike:

  • 60V 30Ah battery = 60-90 miles
  • 60V 40Ah battery = 70-100 miles
  • 60V 50Ah battery = 90-120 miles

Here is another table showing the expected range for a 72v battery with different AHs when paired with a 3000w electric bike:

  • 72V 20Ah battery = 40-70 miles
  • 72V 30Ah battery = 60-90 miles
